This research utilized spatial transcriptomics to map the complex temporal and physical organization of spermatogenesis in mouse testes. By analyzing nearly 900,000 cells at single-molecule resolution, the authors reconstructed the seminiferous epithelial cycle, identifying a circular transcriptional topology that governs tissue timing. A major discovery is that Sertoli cells possess an intrinsic ...去小宇宙查看完整单集简介

Using transcriptome-wide CRISPR-Cas13 screens, researchers identified nearly 800 essential long noncoding RNAs (lncRNAs) that are critical for human cell survival and proliferation across various cell lines. While most of these molecules function in a cell-type-specific manner, a core group of 15 lncRNAs was found to be essential across multiple contexts. Significantly, the study demonstrates that...去小宇宙查看完整单集简介

This research examines the critical link between chronic inflammation and accelerated biological aging. By analyzing four diverse groups of people, scientists discovered that inflammatory proteins related to the interferon pathway do not just correlate with aging but actually serve as causal drivers of epigenetic age acceleration. The findings highlight that epigenetic clocks focused on health spa...去小宇宙查看完整单集简介

Researchers have developed ChromBERT, a genomic foundation model designed to decode the complex "syntax" of interactions among over 1,000 transcription regulators. By pre-training on a massive dataset of human ChIP-seq profiles, the model creates interpretable representations of regulatory networks that function across diverse cell types. ChromBERT excels at cistrome imputation, accurately predict...去小宇宙查看完整单集简介

Researchers utilized CRISPR activation screens to identify the genetic mechanisms that drive cancer-associated glycome remodeling, specifically the production of Siglec ligands that help tumors evade the immune system. By systematically upregulating thousands of genes, the study discovered that hypersialylation is not controlled by a single master regulator but emerges from a complex network of co...去小宇宙查看完整单集简介

This review examines the challenge of identifying cellular points of convergence in autism spectrum disorder (ASD) by utilizing brain transcriptomics and artificial intelligence. The researchers propose an AUC-based framework to quantify the trade-off between a gene’s cell-type specificity and sensitivity, revealing that most ASD-linked genes are broadly expressed across various brain regions rath...去小宇宙查看完整单集简介

This study utilizes CRISPR activation (CRISPRa) screening to identify the genetic drivers behind cancer glycome remodeling, a process where tumors alter their surface sugars to evade the immune system. By forcing the overexpression of thousands of genes, the researchers mapped how specific enzymes and "professional ligands" like CD44 and CSPG4 facilitate binding to inhibitory Siglec receptors on i...去小宇宙查看完整单集简介
