UNASSIGNED The incidence of colorectal cancer (CRC) is increasing, with metastasis of newly diagnosed CRC reported in a large proportion of patients. However, the effect of Korean Red Ginseng extracts (KRGE) on epithelial to mesenchymal transition (EMT) in CRC is unknown. Therefore, we examined the

Only registered users can translate articles

To investigate the effects and underlying mechanisms of Panax quinquefolium saponin (PQS) on energy deficiency in hypoxia-reperfusion (H/R) induced cardiomyocytes.The H/R injury involved hypoxia for 3 h and then reperfusion for 2 h. Cardiomyocytes recruited

Inhibitory effects of ginseng total saponins on hypoxia-induced dysfunction and injuries of cultured astrocytes.

Only registered users can translate articles

The effects of ginseng total saponins (GTS) on hypoxic damage of primary cultures of astrocytes were studied. Hypoxia was created by placing cultures in an air tight chamber that was flushed with 95% N(2)/5% CO(2) for 15 min before being sealed. Cultures showed evidence of significant cell injury

[Effects of Radix Ginseng and Radix Notoginseng formula on expressions of vascular endothelial growth factor receptor-2 and hypoxia-inducible factor-1alpha in ischemic myocardium of rats with acute myocardial infarction].
