title: Effects of raspberry phytochemical extract on cell proliferation, apoptosis, and serum proteomics in a rat model.
abstract: The red raspberry extract possesses potent antioxidant capacity and anticancerous activity in vitro and in vivo. The objective of this study was to determine whether red raspberry extract affected the cell cycle, angiogenesis, and apoptosis in hepatic lesion tissues from a rat model induced by diethylnitrosamine (DEN) as well as changes of serum proteomics. Rats were treated with red raspberry extract (0.75, 1.5, or 3.0 g/kg of body weight) by gavage starting 2 h after DEN administration and continued for 20 wk. Red raspberry extract inhibited cell proliferation, vascular endothelial growth factor VEGF expression, and induced apoptosis in the hepatic lesion tissues. In addition, 2 protein peaks (2597.93 and 4513.88 m/z) were identified to differentially express in the 3.0 g/kg body weight and positive control groups by serum proteomics. These results suggest that a dietary supplement with red raspberry effectively protects against chemically induced hepatic lesions in rats.
