This research identifies a self-contained ketogenic pathway that is essential for the survival of leukemic stem cells (LSCs) in acute myeloid leukemia. While ketone production is typically associated with the liver, these malignant cells utilize fatty acid oxidation to generate the ketone body BHB, which acts as a protective shield against cell death. This metabolic process works by epigenetically...

This research explores how hyocholic acids (HCAs), a primary bile acid produced by the fetal liver, act as a vital immunological buffer during early development. While HCAs are scarce in adults, they dominate neonatal meconium and serum, playing a central role in establishing immune tolerance by promoting anti-inflammatory Treg cells while suppressing pro-inflammatory Th17 cells. This metabolic wi...

A major discovery is that Sertoli cells possess an intrinsic...

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...

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...

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...

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...

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...

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...
