Mechanism of Chinese Herbal Monomers Against Cisplatin-induced Resistance of Ovarian Cancer： A Review / 中国实验方剂学杂志

ABSTRACT

Because the early symptoms of ovarian cancer are not typical and there is a lack of effective screening methods， most patients are diagnosed at an advanced stage， which seriously endangers the health of modern women. Platinum-based chemotherapy after tumor reduction is the first choice for patients with advanced and recurrent ovarian cancer， but almost all patients with recurrent ovarian cancer will eventually develop platinum resistance. Therefore， the search for natural， safe， and effective chemotherapeutic sensitizers has become an urgent and important topic in the study of ovarian cancer. With the increasingly extensive application of traditional Chinese medicine （TCM） in the treatment of cancer， the research on Chinese herbal monomers is also deepening， and the mechanisms of Chinese herbal monomers in intervening in cisplatin （DDP）-induced resistance of ovarian cancer is becoming increasingly clearer. Based on the research status of Chinese herbal monomers available in many Chinese and English databases， it was found that Chinese herbal monomers were involved in the reversal of DDP-induced resistance of ovarian cancer via many routes， mainly through increasing the intracellular drug concentration， reversing the blocked apoptosis， correcting the abnormal intracellular signaling pathway， enhancing DNA damage and inhibiting DNA repair， regulating intracellular autophagy， and suppressing epithelial mesenchymal transition （EMT）. Chinese herbal monomers weaken the resistance of ovarian cancer to DDP from multiple targets and enhance the toxicity of DDP to ovarian cancer cells in vitro and transplanted tumors in vivo. Therefore， Chinese herbal monomers are expected to become natural sensitizers for ovarian cancer chemotherapy with DDP. However， the current studies on Chinese herbal monomers are still confined to the single experimental type， and their action mechanisms and toxic and side effects remain to be further clarified. The application of Chinese herbal monomers for sensitizing DDP chemotherapy still needs to be verified by multi-target， multi-level experimental studies and large-scale clinical studies in the future.
