Transformers in RNA structure prediction: A review

Deep learning - Fri, 2025-04-11 06:00

Comput Struct Biotechnol J. 2025 Mar 17;27:1187-1203. doi: 10.1016/j.csbj.2025.03.021. eCollection 2025.

ABSTRACT

The Transformer is a deep neural network based on the self-attention mechanism, designed to handle sequential data. Given its tremendous advantages in natural language processing, it has gained traction for other applications. As the primary structure of RNA is a sequence of nucleotides, researchers have applied Transformers to predict secondary and tertiary structures from RNA sequences. The number of Transformer-based models in structure prediction tasks is rapidly increasing as they have performed on par or better than other deep learning networks, such as Convolutional and Recurrent Neural Networks. This article thoroughly examines Transformer-based RNA structure prediction models. Through an in-depth analysis of the models, we aim to explain how their architectural innovations improve their performances and what they still lack. As Transformer-based techniques for RNA structure prediction continue to evolve, this review serves as both a record of past achievements and a guide for future avenues.

Comparative Analysis of nnUNet and MedNeXt for Head and Neck Tumor Segmentation in MRI-Guided Radiotherapy

Deep learning - Fri, 2025-04-11 06:00

Head Neck Tumor Segm MR Guid Appl (2024). 2025;15273:136-153. doi: 10.1007/978-3-031-83274-1_10. Epub 2025 Mar 3.

ABSTRACT

Radiation therapy (RT) is essential in treating head and neck cancer (HNC), with magnetic resonance imaging (MRI)-guided RT offering superior soft tissue contrast and functional imaging. However, manual tumor segmentation is time-consuming and complex, and therefore remains a challenge. In this study, we present our solution as team TUMOR to the HNTS-MRG24 MICCAI Challenge which is focused on automated segmentation of primary gross tumor volumes (GTVp) and metastatic lymph node gross tumor volume (GTVn) in pre-RT and mid-RT MRI images. We utilized the HNTS-MRG2024 dataset, which consists of 150 MRI scans from patients diagnosed with HNC, including original and registered pre-RT and mid-RT T2-weighted images with corresponding segmentation masks for GTVp and GTVn. We employed two state-of-the-art models in deep learning, nnUNet and MedNeXt. For Task 1, we pretrained models on pre-RT registered and mid-RT images, followed by fine-tuning on original pre-RT images. For Task 2, we combined registered pre-RT images, registered pre-RT segmentation masks, and mid-RT data as a multi-channel input for training. Our solution for Task 1 achieved 1st place in the final test phase with an aggregated Dice Similarity Coefficient of 0.8254, and our solution for Task 2 ranked 8th with a score of 0.7005. The proposed solution is publicly available at Github Repository.

Head and Neck Tumor Segmentation for MRI-Guided Radiation Therapy Using Pre-trained STU-Net Models

Deep learning - Fri, 2025-04-11 06:00

Head Neck Tumor Segm MR Guid Appl (2024). 2025;15273:65-74. doi: 10.1007/978-3-031-83274-1_4. Epub 2025 Mar 3.

ABSTRACT

Accurate segmentation of tumors in MRI-guided radiation therapy (RT) is crucial for effective treatment planning, particularly for complex malignancies such as head and neck cancer (HNC). This study presents a comparative analysis between two state-of-the-art deep learning models, nnU-Net v2 and STU-Net, for automatic tumor segmentation in pre-RT MRI images. While both models are designed for medical image segmentation, STU-Net introduces critical improvements in scalability and transferability, with parameter sizes ranging from 14 million to 1.4 billion. Leveraging large-scale pre-training on datasets such as TotalSegmentator, STU-Net captures complex and variable tumor structures more effectively. We modified the default nnU-Net v2 by adding additional convolutional layers to both the encoder and decoder, improving its performance for MRI data. Based on our experimental results, STU-Net demonstrated better performance than nnU-Net v2 in the head and neck tumor segmentation challenge. These findings suggest that integrating advanced models like STU-Net into clinical work-flows could remarkably enhance the precision of RT planning, potentially improving patient outcomes. Ultimately, the performance of the fine-tuned STU-Net-B model submitted for the final evaluation phase of Task 1 in this challenge achieved a DSCagg-GTVp of 0.76, a DSCagg-GTVn of 0.85, and an overall DSCagg-mean score of 0.81, securing ninth place in the Task 1 rankings. The described solution is by team SZTU-SingularMatrix for Head and Neck Tumor Segmentation for MR-Guided Applications (HNTS-MRG) 2024 challenge.

Deep learning - Fri, 2025-04-11 06:00

Front Digit Health. 2025 Mar 27;7:1557467. doi: 10.3389/fdgth.2025.1557467. eCollection 2025.

ABSTRACT

BACKGROUND: Type 2 Diabetes Mellitus (T2DM) remains a critical global health challenge, necessitating robust predictive models to enable early detection and personalized interventions. This study presents a comprehensive bibliometric and systematic review of 33 years (1991-2024) of research on machine learning (ML) and artificial intelligence (AI) applications in T2DM prediction. It highlights the growing complexity of the field and identifies key trends, methodologies, and research gaps.

METHODS: A systematic methodology guided the literature selection process, starting with keyword identification using Term Frequency-Inverse Document Frequency (TF-IDF) and expert input. Based on these refined keywords, literature was systematically selected using PRISMA guidelines, resulting in a dataset of 2,351 articles from Web of Science and Scopus databases. Bibliometric analysis was performed on the entire selected dataset using tools such as VOSviewer and Bibliometrix, enabling thematic clustering, co-citation analysis, and network visualization. To assess the most impactful literature, a dual-criteria methodology combining relevance and impact scores was applied. Articles were qualitatively assessed on their alignment with T2DM prediction using a four-point relevance scale and quantitatively evaluated based on citation metrics normalized within subject, journal, and publication year. Articles scoring above a predefined threshold were selected for detailed review. The selected literature spans four time periods: 1991-2000, 2001-2010, 2011-2020, and 2021-2024.

RESULTS: The bibliometric findings reveal exponential growth in publications since 2010, with the USA and UK leading contributions, followed by emerging players like Singapore and India. Key thematic clusters include foundational ML techniques, epidemiological forecasting, predictive modelling, and clinical applications. Ensemble methods (e.g., Random Forest, Gradient Boosting) and deep learning models (e.g., Convolutional Neural Networks) dominate recent advancements. Literature analysis reveals that, early studies primarily used demographic and clinical variables, while recent efforts integrate genetic, lifestyle, and environmental predictors. Additionally, literature analysis highlights advances in integrating real-world datasets, emerging trends like federated learning, and explainability tools such as SHAP (SHapley Additive exPlanations) and LIME (Local Interpretable Model-agnostic Explanations).

CONCLUSION: Future work should address gaps in generalizability, interdisciplinary T2DM prediction research, and psychosocial integration, while also focusing on clinically actionable solutions and real-world applicability to combat the growing diabetes epidemic effectively.

Plant stem and leaf segmentation and phenotypic parameter extraction using neural radiance fields and lightweight point cloud segmentation networks

Deep learning - Fri, 2025-04-11 06:00

Front Plant Sci. 2025 Mar 27;16:1491170. doi: 10.3389/fpls.2025.1491170. eCollection 2025.

ABSTRACT

High-quality 3D reconstruction and accurate 3D organ segmentation of plants are crucial prerequisites for automatically extracting phenotypic traits. In this study, we first extract a dense point cloud from implicit representations, which derives from reconstructing the maize plants in 3D by using the Nerfacto neural radiance field model. Second, we propose a lightweight point cloud segmentation network (PointSegNet) specifically for stem and leaf segmentation. This network includes a Global-Local Set Abstraction (GLSA) module to integrate local and global features and an Edge-Aware Feature Propagation (EAFP) module to enhance edge-awareness. Experimental results show that our PointSegNet achieves impressive performance compared to five other state-of-the-art deep learning networks, reaching 93.73%, 97.25%, 96.21%, and 96.73% in terms of mean Intersection over Union (mIoU), precision, recall, and F1-score, respectively. Even when dealing with tomato and soybean plants, with complex structures, our PointSegNet also achieves the best metrics. Meanwhile, based on the principal component analysis (PCA), we further optimize the method to obtain the parameters such as leaf length and leaf width by using PCA principal vectors. Finally, the maize stem thickness, stem height, leaf length, and leaf width obtained from our measurements are compared with the manual test results, yielding R 2 values of 0.99, 0.84, 0.94, and 0.87, respectively. These results indicate that our method has high accuracy and reliability for phenotypic parameter extraction. This study throughout the entire process from 3D reconstruction of maize plants to point cloud segmentation and phenotypic parameter extraction, provides a reliable and objective method for acquiring plant phenotypic parameters and will boost plant phenotypic development in smart agriculture.

Recent progress in exosomal non-coding RNAs research related to idiopathic pulmonary fibrosis

Idiopathic Pulmonary Fibrosis - Fri, 2025-04-11 06:00

Front Genet. 2025 Mar 27;16:1556495. doi: 10.3389/fgene.2025.1556495. eCollection 2025.

ABSTRACT

Idiopathic Pulmonary Fibrosis (IPF) is a progressive interstitial lung disease characterized by unknown etiology and limited therapeutic options. Recent studies implicate exosomal non-coding RNAs (ncRNAs) as crucial regulators in IPF. These ncRNAs, including long non-coding RNAs (lncRNAs), microRNAs (miRNAs), and circular RNAs (circRNAs), are involved in cellular processes through various mechanisms of selective packaging, intercellular communication, and signaling pathway integration. LncRNAs such as LINC00470 and PVT1 exhibit pro-fibrotic effects, while others like lnc-DC and THRIL show inhibitory roles; some, including UCA1 and MALAT1, demonstrate bidirectional regulation. In miRNAs, pro-fibrotic agents (e.g., miR-486, miR-223) contrast with inhibitory miRNAs (e.g., miR-34a, miR-126), while miR-21 and miR-155 display dual functions. Similarly, circRNAs such as circ_0000479 and circ_0026344 promote fibrosis, whereas circ_0000072 and circ_0000410 act as inhibitors, with certain circRNAs (e.g., circ_002178 and circ_0001246) exhibiting complex regulatory effects. Exosomal ncRNAs modulate key pathways, including TGF-β and Wnt/β-catenin, influencing IPF progression. Despite their potential, challenges remain in exosome isolation, functional characterization of ncRNAs, and clinical translation. Addressing these barriers through innovative research strategies is essential to leverage exosomal ncRNAs in the management and treatment of IPF. This review comprehensively examines the roles of exosomal ncRNAs in IPF, elucidates their mechanisms and pathway interactions, and discusses future perspectives to enhance understanding and therapeutic strategies for this disease.

Systems Biology - Fri, 2025-04-11 06:00

Front Bioeng Biotechnol. 2025 Mar 27;13:1527084. doi: 10.3389/fbioe.2025.1527084. eCollection 2025.

ABSTRACT

INTRODUCTION: Genetically enhanced microorganisms have wide applications in different fields and the increasing availability of omics data has enabled the development of genome-scale metabolic models (GEMs), which are essential tools in synthetic biology. Bartonella quintana str. Toulouse, a facultative intracellular parasite, presents a small genome and the ability to grow in axenic culture, making it a potential candidate for genome reduction and synthetic biology applications. This study aims to reconstruct and analyze the metabolic network of B. quintana to optimize its growth conditions for laboratory use.

METHODS: A metabolic reconstruction of B. quintana was performed using genome annotation tools (RAST and ModelSEED), followed by refinement using multiple databases (KEGG, BioCyc, BRENDA). Flux Balance Analysis (FBA) was conducted to optimize biomass production, and in-silico knockouts were performed to evaluate growth yield under different media conditions. Additionally, experimental validation was carried out by testing modified culture media and performing proteomic analyses to identify metabolic adaptations.

RESULTS: FBA simulations identified key metabolic requirements, including 2-oxoglutarate as a crucial compound for optimal growth. In-silico knockouts of transport genes revealed their essentiality in nutrient uptake. Experimental validation confirmed the role of 2-oxoglutarate and other nutrients in improving bacterial growth, though unexpected decreases in viability were observed under certain supplemented conditions. Proteomic analysis highlighted differential expression of proteins associated with cell wall integrity and metabolic regulation.

DISCUSSION: This study represents a step toward developing B. quintana as a viable chassis for synthetic biology applications. The reconstructed metabolic model provides a comprehensive understanding of B. quintana's metabolic capabilities, identifying essential pathways and growth limitations. While metabolic predictions align with experimental results in key aspects, further refinements are needed to enhance model accuracy and optimize growth conditions.

Apico-basal intercalations enable the integrity of curved epithelia

Systems Biology - Fri, 2025-04-11 06:00

Comput Struct Biotechnol J. 2025 Mar 19;27:1204-1214. doi: 10.1016/j.csbj.2025.03.011. eCollection 2025.

ABSTRACT

Non-invasive force inference based on imaging data has significantly advanced our understanding of the mechanical cues driving morphogenesis. In 2D studies of confluent tissues, these methods allow for the computation of forces acting on cells by analyzing their geometrical features. Here, we present a novel approach for 3D force and energy inference in curved epithelia. Specifically, we focus on tubular epithelia, which form the foundation of many vital organs, including the lungs, kidneys, and vasculature. Our technique analyzes the average mechanical behavior of cells along their apico-basal axis and is based on an optimal parametrization of a vertex model aimed at obtaining effective tissue parameters. We apply our method to in silico data to investigate the mechanical consequences of different 3D cellular packing scenarios. Our results reveal that in squamous epithelia, prismatic cellular shapes are mechanically stable. However, in cubic/columnar tubes, prismatic shapes are incompatible with the adhesion required to maintain tissue integrity. In conclusion, this study indicates that in cubic/columnar epithelia, stability can only be achieved if cells undergo apico-basal intercalations and adopt an alternative shape: the scutoid.

Ultra-processed food consumption affects structural integrity of feeding-related brain regions independent of and via adiposity

Systems Biology - Fri, 2025-04-11 06:00

NPJ Metab Health Dis. 2025;3(1):13. doi: 10.1038/s44324-025-00056-3. Epub 2025 Apr 8.

ABSTRACT

Consumption of ultra-processed foods (UPFs) increases overall caloric intake and is associated with obesity, cardiovascular disease, and brain pathology. There is scant evidence as to why UPF consumption leads to increased caloric intake and whether the negative health consequences are due to adiposity or characteristics of UPFs. Using the UK Biobank sample, we probed the associations between UPF consumption, adiposity, metabolism, and brain structure. Our analysis reveals that high UPF intake is linked to adverse adiposity and metabolic profiles, alongside cellularity changes in feeding-related subcortical brain areas. These are partially mediated by dyslipidemia, systemic inflammation and body mass index, suggesting that UPFs exert effects on the brain beyond just contributing to obesity. This dysregulation of the network of subcortical feeding-related brain structures may create a self-reinforcing cycle of increased UPF consumption.

Anterior hypothalamic nucleus drives distinct defensive responses through cell-type-specific activity

Systems Biology - Fri, 2025-04-11 06:00

iScience. 2025 Mar 12;28(4):112097. doi: 10.1016/j.isci.2025.112097. eCollection 2025 Apr 18.

ABSTRACT

Innate defensive behaviors are essential for survival, allowing animals to appropriately respond to predatory threats. The anterior hypothalamic nucleus (AHN), a key region in the medial hypothalamic defense system, contains both GABAergic and glutamatergic neurons, reflecting a sophisticated balance between inhibitory and excitatory signaling. However, the specific behavioral functions of these neuronal populations have not been systemically examined. Here, we utilized fiber photometry and optogenetic stimulation to investigate the roles of AHN GABAergic, glutamatergic, and CaMKIIa+ neuronal activities in mediating innate defensive behaviors. Our results indicate that AHN GABAergic neurons mediate anxiety-associated investigatory behaviors, while AHN glutamatergic neurons drive escape and freezing responses. The AHN CaMKIIa+ neurons, which exhibit significant heterogeneity, suggest a more nuanced role, potentially balancing escape and freezing responses. Our study provides a foundation for future investigations into the neural circuits underlying innate defensive behaviors and its dysregulation in neuropsychiatric conditions including PTSD and panic disorder.

SciLinker: a large-scale text mining framework for mapping associations among biological entities

Systems Biology - Fri, 2025-04-11 06:00

Front Artif Intell. 2025 Mar 19;8:1528562. doi: 10.3389/frai.2025.1528562. eCollection 2025.

ABSTRACT

INTRODUCTION: The biomedical literature is the go-to source of information regarding relationships between biological entities, including genes, diseases, cell types, and drugs, but the rapid pace of publication makes an exhaustive manual exploration impossible. In order to efficiently explore an up-to-date repository of millions of abstracts, we constructed an efficient and modular natural language processing pipeline and applied it to the entire PubMed abstract corpora.

METHODS: We developed SciLinker using open-source libraries and pre-trained named entity recognition models to identify human genes, diseases, cell types and drugs, normalizing these biological entities to the Unified Medical Language System (UMLS). We implemented a scoring schema to quantify the statistical significance of entity co-occurrences and applied a fine-tuned PubMedBERT model for gene-disease relationship extraction.

RESULTS: We identified and analyzed over 30 million association sentences, including more than 11 million gene-disease co-occurrence sentences, revealing more than 1.25 million unique gene-disease associations. We demonstrate SciLinker's ability to extract specific gene-disease relationships using osteoporosis as a case study. We show how such an analysis benefits target identification as clinically validated targets are enriched in SciLinker-derived disease-associated genes. Moreover, this co-occurrence data can be used to construct disease-specific networks, providing insights into significant relationships among biological entities from scientific literature.

CONCLUSION: SciLinker represents a novel text mining approach that extracts and quantifies associations between biomedical entities through co-occurrence analysis and relationship extraction from PubMed abstracts. Its modular design enables expansion to additional entities and text corpora, making it a versatile tool for transforming unstructured biomedical data into actionable insights for drug discovery.

Surface Modification of Mesoporous Silica Nanoparticles as a Means to Introduce Inherent Cancer-Targeting Ability in a 3D Tumor Microenvironment

Systems Biology - Fri, 2025-04-11 06:00

Small Sci. 2024 Jul 8;4(9):2400084. doi: 10.1002/smsc.202400084. eCollection 2024 Sep.

ABSTRACT

Mesoporous silica nanoparticles (MSNs) have emerged as promising drug carriers that can facilitate targeted anticancer drug delivery, but efficiency studies relying on active targeting mechanisms remain elusive. This study implements in vitro 3D cocultures, so-called microtissues, to model a physiologically relevant tumor microenvironment (TME) to examine the impact of surface-modified MSNs without targeting ligands on the internalization, cargo delivery, and cargo release in tumor cells and cancer-associated fibroblasts. Among these, acetylated MSNs most effectively localized in tumor cells in a 3D setting containing collagen, while other MSNs did so to a lesser degree, most likely due to remaining trapped in the extracellular matrix of the TME. Confocal imaging of hydrophobic model drug-loaded MSNs demonstrated effective cargo release predominantly in tumor cells, both in 2D and 3D cocultures. MSN-mediated delivery of an anticancer drug in the microtissues exhibited a significant reduction in tumor organoid size and enhanced the tumor-specific cytotoxic effects of a γ-secretase inhibitor, compared to the highly hydrophobic drug in free form. This inherent targeting potential suggests reduced off-target effects and increased drug efficacy, showcasing the promise of surface modification of MSNs as a means of direct cell-specific targeting and delivery for precise and successful targeted drug delivery.

Mechanistic Insights Into the Assembly of Functional CRL3 Dimeric Complexes

Systems Biology - Fri, 2025-04-11 06:00

Bioessays. 2025 Apr 10:e202400175. doi: 10.1002/bies.202400175. Online ahead of print.

ABSTRACT

The assembly of Cullin3-based RING E3 ubiquitin ligase (CRL3) complexes is orchestrated in two consecutive steps: the formation of the dimeric BTB domain core and the recruitment of CUL3-RBX1 subunits. Each step is tightly regulated to ensure the formation of complete and functional dimeric CRL3s. The first assembly step is regulated by two mechanisms: "co-co assembly" and proteasome-dependent degradation of aberrant heterodimers. The second step is facilitated by a conserved CUL3 N-terminal assembly (NA) motif. The CUL3 NA motif contributes to the assembly of CRL3s in two aspects: interacting with both BTB domain-containing protein protomers to facilitate complete dimeric assembly, and enhancing the stability of CRL3s by overcoming the tensions generated by conformational entropy during ubiquitin transfer. Given that all Cullin proteins contain N-terminal extensions, we postulate that these extensions, similar to the CUL3 NA motif-contributed assembly, play an important role in the functional regulation of CRLs and thus warrant further investigation.

Systems biology approach delineates critical pathways associated with papillary thyroid cancer: a multi-omics data analysis

Systems Biology - Fri, 2025-04-11 06:00

Thyroid Res. 2025 Apr 11;18(1):15. doi: 10.1186/s13044-025-00230-1.

ABSTRACT

BACKGROUND: Papillary thyroid cancer (PTC) is the most prevalent follicular cell-derived subtype of thyroid cancer. A systems biology approach to PTC can elucidate the mechanism by which molecular components work and interact with one another to decipher a panoramic view of the pathophysiology.

METHODOLOGY: PTC associated genes and transcriptomic data were retrieved from DisGeNET and Gene Expression Omnibus database respectively. Published proteomic and metabolomic datasets in PTC from EMBL-EBI were used. Gene Ontology and pathway analyses were performed with SNPs, differentially expressed genes (DEGs), proteins, and metabolites linked to PTC. The effect of a nucleotide substitution on a protein's function was investigated. Additionally, significant transcription factors (TFs) and kinases were identified. An integrated strategy was used to analyse the multi-omics data to determine the key deregulated pathways in PTC carcinogenesis.

RESULTS: Pathways linked to carbohydrate, protein, and lipid metabolism, along with the immune response, signaling, apoptosis, gene expression, epithelial-mesenchymal transition (EMT), and disease onset, were identified as significant for the clinical and functional aspects of PTC. Glyoxylate and dicarboxylate metabolism and citrate cycle were the most common pathways among the PTC omics datasets. Commonality analysis deciphered five TFs and fifty-seven kinases crucial for PTC genesis and progression. Core deregulated pathways, TFs, and kinases modulate critical biological processes like proliferation, angiogenesis, immune infiltration, invasion, autophagy, EMT, and metastasis in PTC.

CONCLUSION: Identified dysregulated pathways, TFs and kinases are critical in PTC and may help in systems level understanding and device specific experiments, biomarkers, and drug targets for better management of PTC.

Algorithms and tools for data-driven omics integration to achieve multilayer biological insights: a narrative review

Systems Biology - Fri, 2025-04-11 06:00

J Transl Med. 2025 Apr 10;23(1):425. doi: 10.1186/s12967-025-06446-x.

ABSTRACT

Systems biology is a holistic approach to biological sciences that combines experimental and computational strategies, aimed at integrating information from different scales of biological processes to unravel pathophysiological mechanisms and behaviours. In this scenario, high-throughput technologies have been playing a major role in providing huge amounts of omics data, whose integration would offer unprecedented possibilities in gaining insights on diseases and identifying potential biomarkers. In the present review, we focus on strategies that have been applied in literature to integrate genomics, transcriptomics, proteomics, and metabolomics in the year range 2018-2024. Integration approaches were divided into three main categories: statistical-based approaches, multivariate methods, and machine learning/artificial intelligence techniques. Among them, statistical approaches (mainly based on correlation) were the ones with a slightly higher prevalence, followed by multivariate approaches, and machine learning techniques. Integrating multiple biological layers has shown great potential in uncovering molecular mechanisms, identifying putative biomarkers, and aid classification, most of the time resulting in better performances when compared to single omics analyses. However, significant challenges remain. The high-throughput nature of omics platforms introduces issues such as variable data quality, missing values, collinearity, and dimensionality. These challenges further increase when combining multiple omics datasets, as the complexity and heterogeneity of the data increase with integration. We report different strategies that have been found in literature to cope with these challenges, but some open issues still remain and should be addressed to disclose the full potential of omics integration.

Impacts of prenatal nutrition on metabolic pathways in beef cattle: an integrative approach using metabolomics and metagenomics

Systems Biology - Fri, 2025-04-11 06:00

BMC Genomics. 2025 Apr 10;26(1):359. doi: 10.1186/s12864-025-11545-6.

ABSTRACT

BACKGROUND: This study assessed the long-term metabolic effects of prenatal nutrition in Nelore bulls through an integrated analysis of metabolome and microbiome data to elucidate the interconnected host-microbe metabolic pathways. To this end, a total of 126 cows were assigned to three supplementation strategies during pregnancy: NP (control)- only mineral supplementation; PP- protein-energy supplementation during the last trimester; and FP- protein-energy supplementation throughout pregnancy. At the end of the finishing phase, blood, fecal, and ruminal fluid samples were collected from 63 male offspring. The plasma underwent targeted metabolomics analysis, and fecal and ruminal fluid samples were used to perform 16 S rRNA gene sequencing. Metabolite and ASV (amplicon sequence variant) co-abundance networks were constructed for each treatment using the weighted gene correlation network analysis (WGCNA) framework. Significant modules (p ≤ 0.1) were selected for over-representation analyses to assess the metabolic pathways underlying the metabolome (MetaboAnalyst 6.0) and the microbiome (MicrobiomeProfiler). To explore the metabolome-metagenome interplay, correlation analyses between host metabolome and microbiome were performed. Additionally, a holistic integration of metabolic pathways was performed (MicrobiomeAnalyst 2.0).

RESULTS: A total of one and two metabolite modules associated with the NP and FP were identified, respectively. Regarding fecal microbiome, three, one, and two modules for the NP, PP, and FP were identified, respectively. The rumen microbiome demonstrated two modules correlated with each of the groups under study. Metabolite and microbiome enrichment analyses revealed the main metabolic pathways associated with lipid and protein metabolism, and regulatory mechanisms. The correlation analyses performed between the host metabolome and fecal ASVs revealed 13 and 12 significant correlations for NP and FP, respectively. Regarding the rumen, 16 and 17 significant correlations were found for NP and FP, respectively. The NP holistic analysis was mainly associated with amino acid and methane metabolism. Glycerophospholipid and polyunsaturated fatty acid metabolism were over-represented in the FP group.

CONCLUSIONS: Prenatal nutrition significantly affected the plasma metabolome, fecal microbiome, and ruminal fluid microbiome of Nelore bulls, providing insights into key pathways in protein, lipid, and methane metabolism. These findings offer novel discoveries about the molecular mechanisms underlying the effects of prenatal nutrition.

D-chiro-inositol effectively counteracts endometriosis in a mouse model

Systems Biology - Fri, 2025-04-11 06:00

Mol Med. 2025 Apr 11;31(1):134. doi: 10.1186/s10020-025-01178-6.

ABSTRACT

BACKGROUND: Endometriosis, a common condition affecting 5-10% of women of reproductive age, is the growth of endometrial-like tissue outside the uterus, leading to pain and infertility. Current treatments, such as surgery and hormonal therapy, offer limited long-term benefits. This study investigated the potential of D-chiro inositol (DCI), a natural compound that influences ovarian steroidogenesis, to treat endometriosis and compared its efficacy with a progestin drug such as Dienogest (DG).

METHODS: We established a non-surgical mouse model of endometriosis in CD1 mice. Uterine horns were removed from donor mice, cut into fragments and inoculated in recipient mice by intraperitoneal injection. Endometriosis progression was assessed at 15, 21 and 28 days after transplantation, with the 28-day window being the most effective. The mice were then randomly assigned to four experimental groups, which received for 28 days: water (EMS); DCI 0.4 mg/die (DCI); DCI 0.2 mg/die and Dienogest 0.33 ng/die (DCI + DG); DG 0.67 ng/die (DG). At the end of the treatments, endometriotic lesions, ovaries and circulating estradiol levels were analyzed.

RESULTS: The results showed that treatment with DCI, both alone and in combination with DG, significantly reduced the number, size and vascularization of endometriotic lesions compared to the EMS control group. Histological analysis confirmed a decrease in endometriotic foci across all treatment groups, with the most pronounced effects in the DCI group. To investigate the underlying molecular mechanisms, we found that DCI led to a significant reduction in the expression of Sirt1 and an increase in E-Cadherin, indicating a reduction in EMT transition relevant for lesion development. In addition, DCI decreased cell proliferation and,blood vessel formation, as evaluated by PCNA and CD34, respectively. Futhermore, in the ovary, DCI treatment downregulated the expression of aromatase (Cyp19a1), the enzyme critical for estrogen biosynthesis, and increased the number of primordial to antral follicles, suggesting a beneficial effect on ovarian folliculogenesis.

CONCLUSIONS: By modulating proliferation, EMT transition and aromatase activity, DCI emerges as a promising compound for endometriosis treatment.

Drug-induced kidney stones: a real-world pharmacovigilance study using the FDA adverse event reporting system database

Drug-induced Adverse Events - Fri, 2025-04-11 06:00

Front Pharmacol. 2025 Mar 27;16:1511115. doi: 10.3389/fphar.2025.1511115. eCollection 2025.

ABSTRACT

OBJECTIVE: This study aims to identify the drugs most commonly associated with kidney stone-related adverse events using data from the FDA Adverse Event Reporting System (FAERS), providing insights for clinical reference regarding the use of these drugs.

METHODS: We utilized the Medical Dictionary for Regulatory Activities (MedDRA 26.0) preferred term "nephrolithiasis" to identify drug-related adverse events (ADEs) for kidney stones reported in FAERS from Q1 2004 to Q1 2024. Reporting odds ratio (ROR) was used to quantify the signal strength of these ADEs, and new risk signals for kidney stones were compared with drug labeling information to identify any previously unreported risks.

RESULTS: Out of 21,035,995 adverse events reported in FAERS, 38,307 were associated with kidney stones. The top 5 drugs most frequently linked to kidney stone cases were adalimumab (2,636 cases), infliximab (1,266 cases), interferon beta-1a (920 cases), sodium oxybate (877 cases), and teriparatide (836 cases). Notably, certain drugs like lansoprazole (ROR 7.2, 95% CI 6.62-7.84), Xywav (ROR 7.1, 95% CI 6.03-8.35), and teduglutide (ROR 5.54, 95% CI 4.83-6.36) showed significant risk signals. Of the 50 drugs identified, 33 were not previously labeled as carrying a risk of kidney stones.

CONCLUSION: Our analysis of FAERS data revealed new risk signals for kidney stones not indicated in the labels of 33 drugs. Close monitoring is recommended when using these medications, and further research is needed to investigate the mechanisms behind drug-induced kidney stone formation.

Incidence and risk factors for dermatologic adverse events following apalutamide use: a real-world data analysis in the Korean population

Drug-induced Adverse Events - Fri, 2025-04-11 06:00

Prostate Int. 2025 Mar;13(1):10-14. doi: 10.1016/j.prnil.2024.10.002. Epub 2024 Oct 26.

ABSTRACT

PURPOSE: This study aimed to assess the incidence, severity, and onset of dermatologic adverse events (dAEs) in Korean patients treated with apalutamide for metastatic hormone-sensitive prostate cancer (mHSPC) and to identify clinical and laboratory predisposing factors.

MATERIALS AND METHODS: We retrospectively analyzed data of patients treated with apalutamide for mHSPC at a tertiary referral center in Korea between April 2023 and March 2024. Patients with a radical prostatectomy history or insufficient data were excluded. The onset, severity, and management of dAEs were evaluated and compared between patients with and without dAEs. Clinical and laboratory data from 1 month prior to apalutamide administration were collected. Logistic regression was performed to identify predictors of dAEs, and the predictive value of serum albumin levels was analyzed using the receiver operating characteristic (ROC) curve.

RESULTS: Twenty-six (40.0%) of the 65 patients developed dAEs, including nine (13.8%) with Grade ≥3 events. The median onset of dAEs was 66.5 (45-78) days. Patients with dAEs had significantly lower initial prostate-specific antigen levels (70.4 vs. 301.6 ng/mL), higher Eastern Cooperative Oncology Group Performance Status (ECOG-PS; 30.8% vs. 5.1%), and lower serum albumin levels (3.8 vs. 4.1 g/dL). Logistic regression identified elevated Eastern Cooperative Oncology Group-Performance Status (ECOG-PS) and hypoalbuminemia as significant predictors of dAEs. ROC analysis for serum albumin levels produced an area under the curve of 0.739, with a cutoff value of 3.85 g/dL, yielding a sensitivity and specificity of 65.4% and 74.4%, respectively.

CONCLUSION: dAEs are prevalent in Korean patients treated with apalutamide for mHSPC, with ECOG-PS and serum albumin levels identified as significant risk factors.
