Polysaccharides Derived From Balanophora Polyandra Significantly Suppressed The Proliferation Of Ovarian Cancer Cells Through P53-Mediated Pathway

Ovarian cancer (OC) is ranked the first among the cancers threatening women's health. It attracts tremendous attention of cancer researchers because of its extremely high mortality rate. Recent studies have indicated that traditional herbal medicines ( THMs) can play a pivotal role in cancer prevention and treatment. THMs are gaining popularity as a source of anti-cancer agents. The plant of Balanophora polyandra, which has been used as a traditional herbal medicine, has been known for exhibiting potential haemostatic, analgesic, anti-inflammatory and anti-cancer properties. However, few studies on inhibitory effect of B. polyandra on OC have been performed. In the present study, we found that B. polyandra polysaccharides (BPP) induced cell cycle arrest at S phase, triggered apoptosis and inhibited migration and invasion of OC cells. Furthermore, we also found that there was a potential and close relationship between BPP and P53-mediated pathway. Overall, these findings suggest that BPP can be a potential therapeutic agent for the treatment of OC.
