Androgen receptor (AR) signalling contributes to male predominance in hepatocellular carcinoma (HCC), which is more pronounced in HBV-endemic areas. Cell cycle-related kinase (CCRK) is essential for AR-induced hepatocarcinogenesis but its molecular function in HBV-associated HCC remains obscure. To determine the

DCs contribute to immune homeostasis under physiological conditions and regulate the immune activation during infection. The deubiquitinase A20 inhibits the activation of NF-κB-dependent immune reactions, and prevents the hyperactivation of DCs under steady-state conditions. However, the role of DC-specific A20

A new type of enzyme hydrolyzing the elastase substrate succinyl-L-alanyl-L-alanine-4-nitroanilide has been found in cell-free rheuma todi synovial fluid. Normal plasma and osteoarthritic synovial fluid contained relatively little enzyme. The pH optimum was 8.0. Unexpectedly, the enzyme activity was not

The olfactory system of fish comprises several classes of olfactory sensory neurons (OSNs). The odourants L-alanine and taurocholic acid (TCA) specifically activate microvillous or ciliated OSNs, respectively, in fish. We recorded electro-olfactograms (EOG) in fathead minnows (Pimephales promelas; a laboratory-reared
