Quiescent stem cells contribute to tissue homeostasis and repair in adult mammals. We identified a tumor suppressor PRDM2, as an epigenetic regulator induced in quiescent muscle stem cells as well as in cultured quiescent myoblasts. To delineate the functions of PRDM2 in muscle cells, we compared the gene expression profiles of control and PRDM2 knockdown myoblasts in growing, differentiating and quiescent conditions (GEO accession number: GSE 58676). To identify the direct targets of PRDM2 and the promoters co-associated with H3K9me2 (mark catalyzed by PRDM2), ChIP-Chip analysis was performed (GSE58748). In this report we discuss in detail the methodology used to identify PRDM2 regulated genes and classify them into potential direct and indirect targets.

Multiple investigations have demonstrated the crucial involvement of T-cell exhaustion (TEX) in anti-tumor immune response and their strong correlation with prognosis. This study aimed at creating a strong signature using TEX for gastric cancer through bioinformatics analysis and experimental validation. We utilized data from The Cancer Genome Atlas (TCGA) databases to retrieve RNA-seq data from patients with stomach adenocarcinoma (STAD).

Article Synopsis
  • The study investigates DNA methylation changes in individuals with hepatocellular carcinoma (HCC), looking at saliva samples from patients and matched controls to explore their potential for HCC screening.* -
  • Out of 25 candidate genes linked to HCC, 16 showed detectable differences in DNA methylation between HCC cases and controls, indicating possible biomarkers for the disease.* -
  • The findings suggest that using saliva for DNA testing could be a convenient and effective alternative to blood tests for HCC screening, warranting further research in this area.*

Oxygen and nutrient deprivation are common features of solid tumors. Although abnormal alternative splicing (AS) has been found to be an important driving force in tumor pathogenesis and progression, the regulatory mechanisms of AS that underly the adaptation of cancer cells to harsh microenvironments remain unclear. Here, we found that hypoxia- and nutrient deprivation-induced asparagine endopeptidase (AEP) specifically cleaved DDX3X in a HIF1A-dependent manner.

Background: Colorectal cancer (CRC) is the third most deadly and fourth most diagnosed cancer worldwide. Despite the progress in early diagnosis and advanced therapeutic options, CRC shows a poor prognosis with a 5 year survival rate of ~ 45%. PRDM2/RIZ, a member of PR/SET domain family (PRDM), expresses two main molecular variants, the PR-plus isoform (RIZ1) and the PR-minus (RIZ2).
