Researchers have identified a novel long non-coding RNA named HOTSCRAMBL, which plays a vital role in regulating human hematopoietic stem cells (HSCs). A specific inherited genetic variant, rs17437411, disrupts this RNA’s structure and impairs its ability to recruit the splicing factor SRSF2 to the HOXA9 gene. This structural failure leads to inefficient HOXA9 splicing, which reduces the self-rene...去小宇宙查看完整单集简介

This study utilizes MERFISH spatial transcriptomics to create a near-complete molecular atlas of the mouse primary olfactory system, mapping the expression of approximately 1,100 olfactory receptors. The researchers identified two distinct spatial gradients in the olfactory epithelium—central-to-peripheral and apical-to-basal—which directly correspond to organized projection axes in the olfactory ...去小宇宙查看完整单集简介

This article reveals that the mammalian nose utilizes a sophisticated spatial map to organize the sense of smell, challenging previous theories of random receptor distribution. Research demonstrates that approximately 1,100 olfactory receptors are expressed at specific, predictable locations along the dorsoventral axis of the nasal tissue. This precise organization is governed by a transcriptional...去小宇宙查看完整单集简介

This research presents a comprehensive map of the human genetic interaction network by utilizing CRISPR-Cas9 technology to analyze approximately four million gene pairs in HAP1 cells. The study identifies roughly 89,000 high-confidence interactions, revealing a hierarchical organization that connects genes to specific protein complexes, pathways, and cellular processes. By comparing these results ...去小宇宙查看完整单集简介

This research identifies how cancer cells develop resistance to tri-complex inhibitors (TCIs), which are molecular glues designed to neutralize oncogenic RAS signaling. By analyzing patient samples and preclinical models, the authors discovered that specific mutations disrupt the RAS-inhibitor-CYPA synthetic complex. Some alterations, like those at KRAS residue Y64, physically prevent the drug fro...去小宇宙查看完整单集简介

This paper presents PathSeq-T2T, a highly precise computational pipeline designed to identify microbial DNA within human tumor samples while rigorously removing host genetic material and environmental contaminants. By applying this technology to over 16,000 cancer genomes, researchers discovered that orodigestive cancers—such as those in the mouth, stomach, and colon—harbor complex, multi-kingdom ...去小宇宙查看完整单集简介

The paper introduces Multi-Embed, a new computational framework designed to bridge the gap between physical disease structures and complex molecular data. While traditional methods often struggle with transparency or limited data scales, this self-supervised learning tool creates a shared digital space to align tissue images with genetic and protein profiles. By utilizing an auto-encoder architect...去小宇宙查看完整单集简介

The research examines how the spatial positioning of leukaemic stem cells (LSCs) within different bone marrow regions fundamentally dictates their survival and disease progression. Studies using mouse models demonstrate that LSCs remain quiescent and stem-like when localized in the metaphysis, whereas moving to the central marrow induces cell-cycle activity and therapeutic vulnerability. This loca...去小宇宙查看完整单集简介

This technical report introduces a transgene-free human embryo model known as the peri-gastrulation trilaminar embryonic disc (PTED) embryoid. Created from primed human pluripotent stem cells, these 3D structures successfully mimic the self-organizing properties of the critical human peri-gastrulation phase. The models feature a trilaminar disc situated between an amniotic-like sac and a yolk sac-...去小宇宙查看完整单集简介
