Abstract
The pleiotropic second messenger adenosine 3',5'-cyclic monophosphate (cAMP) regulates a myriad of biological processes under both physiological and pathophysiological conditions. Exchange protein directly activated by cAMP 1 (EPAC1) mediates the intracellular functions of cAMP by acting as a guanine nucleotide exchange factor for the Ras-like Rap small GTPases. Recent studies suggest that EPAC1 plays important roles in immunomodulation, cancer cell migration/metastasis, and metabolism. These results, coupled with the successful development of EPAC-specific small molecule inhibitors, identify EPAC1 as a promising therapeutic target for cancer treatments.
摘要
多效性第二信使3',5'-环磷酸腺苷（cAMP）在生理和病理生理条件下调节无数生物过程。cAMP直接激活的交换蛋白1（EPAC1）通过充当Ras样Rap小GTP酶的鸟嘌呤核苷酸交换因子来介导cAMP的细胞内功能。最近的研究表明，EPAC1在免疫调节、癌细胞迁移/转移和代谢中发挥重要作用。这些结果，再加上EPAC特异性小分子抑制剂的成功开发，将EPAC1确定为癌症治疗的一个有前景的治疗靶点。
