abstract：:Hepatitis C Virus core protein (HCVc) plays important roles in the development of intrahepatic cholangiocarcinoma (ICC). MicroRNAs (miRNAs) contribute to tumor progression by interacting with downstream target genes. However, the regulation and role of miRNAs in HCV-related intrahepatic cholangiocarcinoma (HCV-ICC) is...

Despite their discovery as tumor suppressors, we demonstrated that all these proteins are phospholipid-metabolizing enzymes, such as phospholipase (PL) A1 /A2 and acyltransferase. We thus proposed to rename HRASLS1-5 as PLA/ac...
