MicroRNA (miRNA) loaded Argonaute (AGO) complexes regulate gene expression via direct base pairing with their mRNA targets. Previous works suggest that up to 60% of mammalian transcripts might be subject to miRNA-mediated regulation, but it remains largely unknown which fraction of these interactions are functional in a specific cellular context. Here, we integrate transcriptome data from a set of miRNA-depleted mouse embryonic stem cell (mESC) lines with published miRNA interaction predictions and AGO-binding profiles. Using this integrative approach, combined with molecular validation data, we present evidence that < 10% of expressed genes are functionally and directly regulated by miRNAs in mESCs. In addition, analyses of the stem cell-specific miR-290-295 cluster target genes identify TFAP4 as an important transcription factor for early development. The extensive datasets developed in this study will support the development of improved predictive models for miRNA-mRNA functional interactions.

Background: Acupuncture is a widely recognized complementary therapy with proven therapeutic benefits; however, concerns regarding patient safety persist due to adverse events ranging from minor complications to severe outcomes like pneumothorax and nerve injury.
Objective: This study aims to identify common adverse events in acupuncture, propose innovative risk mitigation strategies, establish standardized best practices, enhance practitioner training, and examine global disparities in safety protocols.
Design: Comprehensive review of existing literature, clinical case studies, and international safety guidelines.

Background: Lung cancer remains the leading cause of cancer-related mortality globally, primarily due to late-stage diagnosis, molecular heterogeneity, and therapy resistance. Key biomarkers such as EGFR, ALK, KRAS, and PD-1 have revolutionized precision oncology; however, comprehensive structural and clinical validation of these targets is crucial to enhance therapeutic efficacy.
Methods: Protein sequences for EGFR, ALK, KRAS, and PD-1 were retrieved from UniProt and modeled using SWISS-MODEL to generate high-confidence 3D structures.

Background: Spinal cord injury (SCI) often leads to severe motor and sensory impairments, and current treatment methods have not achieved complete neural repair. In recent years, exosomes have become a research focus in the treatment of nerve injuries due to their important roles in intercellular information transfer, immune regulation, and neural repair. Our study conducts a scientometric analysis to map the research landscape related to exosomes in SCI.
