p16 Stimulates CDC42-dependent migration of hepatocellular carcinoma cells.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide. Tumor dissemination to the extra-hepatic region of the portal vein, lymph nodes, lungs or bones contributes to the high mortality seen in HCC; yet, the molecular mechanisms responsible for HCC metastasis remain unclear. Prior studies have suggested a potential link between accumulated cytoplasm-localized p16 and tumor progression.

Single-step protein purification by back flush in ion exchange chromatography.

Ion exchange chromatography, one of the major procedures for protein purification, seldom provides single-step purification due to a lack of specific affinity. In this work, a novel and simple method called "back flush" (i.e.
