Diet-induced rewiring of the Wnt gene regulatory network connects aberrant splicing to fatty liver and liver cancer in DIAMOND mice
DIAMOND mice develop HCC in the context of obesity and insulin resistance To investigate in depth the genome-wide transcriptional and epigenetic changes that occur during development of MAFLD and obesity-related hepatocellular carcinoma (HCC), we performed RNA-sequencing (RNA-seq) and Chromatin ImmunoPrecipitation-sequencing (ChIP-seq) of liver tumours (HCC) and liver control tissue (FL)…
Novel Rett syndrome variant shines light on n
Rett syndrome is a rare devastating neurological disorder that primarily affects young girls and manifests as an impaired ability to walk and talk, along with characteristic ‘hand-wringing’ movements, seizures, and cognitive disability. This incurable condition results from mutations in the methyl-CpG binding protein 2 (MECP2) gene that impairs the role…
epialleleR: an R/Bioconductor package for sensitive allele-specific methylation analysis in NGS data | GigaScience
Abstract Low-level mosaic epimutations within the BRCA1 gene promoter occur in 5–8% of healthy individuals and are associated with a significantly elevated risk of breast and ovarian cancer. Similar events may also affect other tumor suppressor genes, potentially being a significant contributor to cancer burden. While this opens a new…

Decoding Life’s Secrets: Researchers Solve Protein Mystery
Proteins in human cells commonly undergo N-terminal acetylation, a modification by the enzyme group N-terminal acetyltransferases (NATs), the function of which has been largely mysterious. Recent research using CRISPR-Cas9 technology and collaborative studies in fruit flies reveal that this modification protects proteins from degradation, playing a crucial role in longevity…
