Regulation of Pyroptosis in Gastric Cancer by Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

ABSTRACT

Pyroptosis， a new type of inflammatory programmed cell death， is different from apoptosis， necrosis， cytosis， ferroptosis， and autophagy. Pyroptosis is dependent on the activation of cysteine aspartate-specific protease （Caspase）， which cleaves key mediator proteins to form pores in the cell membrane and induces the maturation and release of the proinflammatory cytokines interleukin-1β and interleukin-18 into the extracellular environment， resulting in a cascade of inflammatory reactions. Gastric cancer as a malignant tumor of the digestive tract is refractory and has poor prognosis， and the chemoradiotherapy of this disease may lead to a variety of complications. At present， the pathogenesis of gastric cancer remains unclear. Studies have proved that pyroptosis is associated with the occurrence and development of gastric cancer， which has attracted wide attention. Pyroptosis is a double-edged sword for gastric cancer. On the one hand， it can release the contents of proinflammatory cells to amplify or maintain inflammation and induce the "inflammation-cancer" transformation of cells. On the other hand， pyroptosis can enhance the sensitivity of drugs for chemotherapy to improve the therapeutic effect and survival. In recent years， the anti-tumor mechanism of traditional Chinese medicine （TCM） has become a research hotspot as TCM has demonstrated significant effects in clinical application. Therefore， the regulation of pyroptosis by TCM may be a new direction for the treatment of gastric cancer in the future. Based on the available studies， this paper introduces the roles of pyroptosis-associated key proteins in the occurrence and development of gastric cancer. Furthermore， this paper summarizes the effects of TCM prescriptions and active ingredients on alleviating gastric mucosal damage， reducing the incidence of gastric cancer， and preventing tumor metastasis and recurrence by mediating pyroptosis pathways， aiming to provide new ideas for deciphering the mechanism of pyroptosis and exploring the TCM treatment of gastric cancer in the future.
