A c-Met inhibitor tivantinib is a candidate anticancer agent for patients with hepatocellular carcinoma (HCC), and CYP2C19 is the key metabolic enzyme for tivantinib. Previous Japanese phase I studies in patients with solid tumors (except HCC) recommend 360 mg twice daily (BID) and 240 mg BID for CYP2C19 extensive metabolizers (EM) and poor metabolizers(More)
Transforming growth factor-β1 (TGFβ1) plays a pivotal role in fibrosis in various organs including the lung. Following pulmonary injury, TGFβ1 stimulates conversion of fibroblasts to myofibroblasts that are mainly characterized by up-regulation of α-smooth muscle actin (αSMA) expression, and the resulting excess production of extracellular matrix proteins(More)
Increases in the level of cyclooxygenase (COX)-2 and prostanoids such as prostaglandin E(2) (PGE(2)) are considered biomarkers of colorectal cancer. Therefore, non-steroidal anti-inflammatory drugs (NSAID) have been used to reduce the risk of cancer development by reducing prostanoid biosynthesis as COX inhibitors. Along with their activity as COX(More)
