RNA结合蛋白Musashi1在结直肠癌中的表达及临床意义

Expression and clinical significance of RNA-binding protein Musashi1 in colorectal cancer

Musashi1（Msi1）是一种进化保守的RNA结合蛋白,同时它是肠道、神经等多种组织中的干细胞标志物,对于维持自我更新与分化之间的平衡具有重要作用.近年来研究发现Msi1在多种肿瘤组织尤其是结直肠癌中高表达,参与调控细胞周期、增殖、凋亡等过程,逐渐成为多种癌变的关键调节剂,有望成为肿瘤治疗的新靶点.

Musashi1 （Msi1） is an evolutionary conservative RNA-binding protein （RBP）,and it is a stem marker in a variety of organizations,including intestinal,neural system.Msi1 maintains the balance between self-renewal and differentiation.Recently,many researchers report that Msi1 is overexpressed in many types of tumors,especially in colorectal neoplasms,participating in the regulation of cell cycle,proliferation,apoptosis and so on.Msi1 becomes a key regulator of many cancers,which is expected to turn into a new target for cancer therapy.
