Evaluation of the cytotoxic anticancer effect of polysaccharide of Nepeta septemcrenata
Beni-Suef University Journal of Basic and Applied Sciences(2021)
Abstract
Background Promoting cancer cells apoptosis is one of the effective methods to treat cancer. Human hepatocellular carcinoma (HepG2) and colorectal cancer (HCT-116) cell lines were used in the present study to evaluate the cytotoxic and anticancer properties of Nepeta septemcrenata Polysaccharide (NSP). Result Treatment of the two examined cells with NSP displayed a significant cytotoxicity towards HepG2 in a dose-dependent manner; meanwhile, its effect on HCT-116 was obtained under the influence of low doses. The quantitative real- time PCR (QRT-PCR) investigation revealed that NSP significantly up-regulated the expression levels of p53, p16, Fas, Fas-L, Bax, caspases-3, caspase-9, and TNF-α in association with down-regulation of cyclin D1, TERT, and BCL2. These findings declare the apoptotic characteristic of NSP.NSP, can also inhibit the development of cancer cells through the down-regulation of TGF-β and VEGF. Conclusions Our results suggested that the polysaccharides isolated from N . septemcrenata possess anticancer properties that could be explored for the development of novel anticancer agents.
