肿瘤及其微环境源性外泌体miRNAs在致癌机制、肿瘤诊断和治疗中的研究进展

摘要

Exosomal miRNAs, derived from tumor cells or their microenvironment, could promote the proliferation, migration and invasion of tumor cells;and enhance tumor metastasis via regulating information exchange between tumor cells and immune cells or metastatic target organs;and induce tumor resistance to cisplatin and gemcitabine;meanwhile, detecting the exosomal miRNAs in the serum and saliva of cancer patients suggested the potential of application in cancer diagnosis and prognosis assessment.%肿瘤及其微环境来源的外泌体miRNAs可以促进肿瘤细胞增殖和侵袭运动;通过介导肿瘤细胞与免疫细胞、转移靶器官间的信息交流促进肿瘤细胞定向转移;诱发肿瘤细胞对顺铂和吉西他滨等的耐药;同时针对肿瘤患者血清和唾液中外泌体miRNAs的检测显示出应用于肿瘤诊断和预后判断的潜在重要价值.
