JAK2 Mediates the Regulation of Pept1 Expression by Leptin in the Grass Carp () Intestine.

Oligopeptide transporter 1 (Pept1) is located on the brush border membrane of the intestinal epithelium and plays an important role in dipeptide and tripeptide absorption from protein digestion. In this study, we cloned and characterized the cDNA sequence of Janus kinase 2 (JAK2) from . The expression patterns of JAK2 in various tissues and developmental stages were characterized by quantitative real-time PCR (qRT-PCR).

Angiogenesis inhibition in vascular endothelial cells by terpenoid compounds from Bletilla striata is via apoptosis pathway.

The inhibitive effects on angiogenesis and the potential mechanism by terpenoids from Bletilla striata were investigated in the study. Terpenoids were separated and purified from Bletilla striata by extraction and chromatography. The terpenoid and its crude extracts were used to treat on blood vessel of chick chorioallantoic membrane (CAM), as well as human umbilical vein endothelial cell (HUVEC).
