Cancer cells seed distant tissues and remain dormant before re-entering the cell cycle to form metastases. How tumor dormancy is maintained and how cells exit dormancy is poorly understood. A study shows that the lncRNA MALAT1 reactivates dormant cancer cells by upregulating serpin protease inhibitors in tumor cells to evade CD8+ T cells.

MALAT1 保护休眠肿瘤细胞免遭免疫消除

癌细胞在远处组织中播种并保持休眠状态，然后重新进入细胞周期形成转移。人们对肿瘤休眠如何维持以及细胞如何退出休眠知之甚少。一项研究表明，lncRNA MALAT1 通过上调肿瘤细胞中的丝氨酸蛋白酶抑制剂来逃避 CD8+ T 细胞，从而重新激活休眠的癌细胞。
