Effect of Autophagy in Treatment of Tumors with Traditional Chinese Medicine / 中国实验方剂学杂志

ABSTRACT

The cure of tumors is a difficulty in the world, and both the quality of life and the survival rate of patients remain low. Therefore, it is very meaningful to find a drug target to inhibit the occurrence and development of tumors. In recent years, autophagy or self-phagocytosis has become a hotspot of medical research. It can remove damaged or excess organelles from cells, be survived from external environmental pressures, and affect the survival, metabolism, differentiation, aging and death of tumor cells. The biological behavioral process plays important roles in remodeling and maintaining the dynamic balance of cell survival, especially in close relations to tumor development. Autophagy is also a double-edged sword in effect on a single tumor cell and the entire tumor. When the autophagy of the tumor cells is abnormal, or the cells are unable to remove the damaged substances in time under the conditions of hypoxia and nutrient deficiency, autophagy is beneficial to the proliferation and survival of the tumor cells. Contrarily, moderate autophagy acts as an inhibitor of tumors and has an anti-tumor effect. Traditional Chinese medicine (TCM) has a long history of controlling tumors, with the advantages of low toxicity and multiple targets. Through overall and local therapies, it has a comprehensive therapeutic effect in cancer. With the deepening of tumor autophagy research, in addition to western medicine researches on tumor autophagy, there are also domestic and foreign researches on the autophagy in single herb and TCM compounds. The latest insights into the molecular mechanism of autophagy have led to the discovery of potential drug targets. At the same time, TCM researches have made some progress in tumor autophagy. The authors review the research progress of autophagy in TCM and the research progress of effect of TCM in regulating tumor autophagy, in the hopes to provide useful reference for effect of TCM in the treatment of autophagy.
