Catalase, an endogenous antioxidant enzyme, is thought to have rescue effects on hepatic fibrosis. In this study, the regulation of catalase in CCl₄-induced hepatic fibrogenesis was investigated. Our results indicated that catalase expression was decreased upon CCl₄ treatment in a time-dependent manner, while the expression of several profibrosis and proangiogenic factors, including transforming ...

TEK, or TIE-2, is a receptor tyrosine kinase (RTK) that is known as a functioning molecule of vascular endothelial cells. TEK comprises a subfamily of RTK with TIE, and these two receptors play critical roles in vascular maturation, maintenance of integrity and remodeling. We generated mAb against the extracellular domain of human TEK protein to elucidate its expression pattern in human hematop...
