METTL3-Mediated m6A Methylation of USP21 Contributes to Hepatocellular Carcinoma Progression by Stabilizing H2BFS Through Deubiquitination.

Deubiquitinases play essential roles in hepatocellular carcinoma (HCC) progression, however, the role of ubiquitin-specific peptidase 21 (USP21) in HCC development remains unclear. The present work aims to analyze the effect of USP21 on tumor property of HCC cells and the underlying mechanism. mRNA expression levels of USP21 and H2BFS were analyzed by quantitative real-time polymerase chain reaction.

Presentation of gallbladder torsion at an abnormal position: A case report.

Background: Gallbladder torsion is a rare acute abdominal condition that requires emergency surgery. It occurs more commonly in elderly people and in women in the adult population. Diagnosis is a challenge as non-specific symptoms and signs have been reported on ultrasonography, computed tomography and magnetic resonance imaging.
