Classification of tropomyosin components into an alpha-like or a beta-like family by partial peptide mapping.

abstract：:The role of the RNA-binding protein human antigen R (HuR) in hepatocarcinogenesis is still elusive. By employing short hairpin (sh)RNA-dependent knockdown approach, we demonstrate that lymphotoxin α (LTα) is a target of posttranscriptional gene regulation by HuR in hepatocellular carcinoma (HepG2) cells. Consequently,...
