乳腺癌已成为全球女性患者最大的癌症负担。在中国,近10%的女性乳腺癌患者发病与遗传相关,受多个易感基因调控。乳腺癌患者存在多发性内分泌肿瘤1型(multiple endocrine neoplasia type 1,MEN1)基因显著突变,MEN1突变女性患乳腺癌风险...乳腺癌已成为全球女性患者最大的癌症负担。在中国,近10%的女性乳腺癌患者发病与遗传相关,受多个易感基因调控。乳腺癌患者存在多发性内分泌肿瘤1型(multiple endocrine neoplasia type 1,MEN1)基因显著突变,MEN1突变女性患乳腺癌风险显著增加,发病年龄提前。关于MEN1影响乳腺癌发病与进展的系统研究仍然有限。因此,本文将基于MEN1基因和MEN1编码的menin蛋白的结构、功能作一概述,以探讨MEN1与menin在乳腺癌发生发展及内分泌治疗中的作用机制,并介绍了基于menin的乳腺癌潜在治疗靶点,旨在为乳腺癌的早期筛查及个体化防治提供理论支持和科学指导。展开更多
