富含丝氨酸/丝氨酸的剪接因子(serine/case-rich splicing factors,SRs)属于富含丝氨酸的蛋白质家族,在前体RNA的剪接过程中起着极其重要的作用。SR识别前体RNA上的剪接元件,然后募集和组装剪接体,以促进或抑制剪接事件的发生。在肿瘤中,SRs的异常表达引起RNA的异常剪接,有助于肿瘤细胞的增殖、迁移和凋亡抵抗。本文综述了SRs在各种肿瘤中的重要作用,并讨论了分析肿瘤中mRNA选择性剪接事件的前景。此外,我们强调了挑战,并讨论了通过SRs家族成员识别癌症治疗新的潜在靶点的前景。
The serine/arginine-rich splicing factors (SRs) belong to the serine arginine-rich protein family, which plays an extremely important role in the splicing process of precursor RNA. The SRs recognize the splicing elements on precursor RNA, then recruit and assemble spliceosome to promote or inhibit the occurrence of splicing events. In tumors, aberrant expression of SRs causes abnormal splicing of RNA, contributing to proliferation, migration and apoptosis resistance of tumor cells. Here, we reviewed the vital role of SRs in various tumors and discussed the promise of analyzing mRNA alternative splicing events in tumor. Further, we highlight the challenges and discussed the perspectives for the identification of new potential targets for cancer therapy via SRs family members.
