The SMARCA4 mutation facilitates chromatin remodeling and confers PRMT1/SMARCA4 inhibitors sensitivity in colorectal cancer.

Genomic studies have demonstrated a high frequency of genetic alterations in components of the SWI/SNF complex including the core subunit SMARCA4. However, the mechanisms of tumorigenesis driven by SMARCA4 mutations, particularly in colorectal cancer (CRC), remain largely unknown. In this study, we identified a specific, hotspot mutation in SMARCA4 (c.

Avoidance of urinary drainage during perioperative period of open elective colonic resection within enhanced recovery after surgery programme.

Background: Urinary catheterization (UC) is a conventional perioperative measure for major abdominal operation. Optimization of perioperative catheter management is an essential component of the enhanced recovery after surgery (ERAS) programme. We aimed to investigate the risk factors of urinary retention (UR) after open colonic resection within the ERAS protocol and to assess the feasibility of avoiding urinary drainage during the perioperative period.

PRMT1-mediated H4R3me2a recruits SMARCA4 to promote colorectal cancer progression by enhancing EGFR signaling.

Background: Aberrant changes in epigenetic mechanisms such as histone modifications play an important role in cancer progression. PRMT1 which triggers asymmetric dimethylation of histone H4 on arginine 3 (H4R3me2a) is upregulated in human colorectal cancer (CRC) and is essential for cell proliferation. However, how this dysregulated modification might contribute to malignant transitions of CRC remains poorly understood.
