P2X7受体与乳腺癌发生发展关系的研究进展

Recent progress on the relationship between P2X7R and breast cancer

P2X7受体(P2X7 purinergic receptor,P2X7R)属于双跨膜阳离子通道型受体,在体内受ATP门控,激活后可产生诸如阳离子通道开放、信号通路激活、炎症介质释放和细胞凋亡等效应,在多种肿瘤及炎症性疾病的发生发展过程中发挥重要作用。研究表明,P2X7R在乳腺癌中表达异常,并通过激活一系列信号通路,影响乳腺癌的发生和发展;多种microRNA也可通过调节P2X7R基因的表达而促进乳腺癌的发生发展。文章对P2X7R的研究进展及其异常表达与乳腺癌的关系进行了综述。

As the P2X receptor family has become a research hotspot in recent years, the study on P2X7 receptor has also received extensive attention. P2X7 receptor (P2X7R) is a dual-transmembrane cation-channel receptor, which is gated in vivo by adenosine triphosphate (ATP) and can be activated. Activated P2X7 receptor can produce such effects as cationic channel opening, signal pathway activation, inflammatory mediator release and cell apoptosis. It plays an important role in the development of various tumors and inflammatory diseases. Studies have shown that the abnormal expression of P2X7 receptor affects the occurrence and development of breast cancer by activating a series of signaling pathways, which is expected to become a new target for designing anti-breast cancer drugs. Other studies have shown that multiple microRNAs can promote the occurrence and development of breast cancer by regulating the expression of P2X7 receptor gene. In this review, we reviewed the recent research advances of P2X7 receptor and the relationship between breast cancer and its abnormal expression.
