摘要 目的:研究调控前体mRNA(pre-mRNA)可变剪切的原癌基因SRSF3对细胞有丝分裂的重要功能蛋白SPAG5的外显子3的可变剪切的调控作用。方法:在人口腔鳞状上皮细胞癌细胞系CAL 27中应用RNAi技术降低SRSF3的表达,通过逆转录PCR(RT-PCR)检测SPAG5外显子3的可变剪切。结果:在CAL 27细胞中抑制SRSF3表达时,抑制了全长的SPAG5的表达,增加了较短的SPAG5的剪切异构体的表达。结论:SRSF3可以调控SPAG5外显子3的可变剪切,并可能影响了SPAG5蛋白的表达水平和有丝分裂。 Objective.. To study the effect of SRSF3 on alternative splicing of SPAG5 exon3 in oral squamous cell carcinoma (OSCC). Methods.. SRSF3 was knocked down using siRNA in OSCC CAL27 cells. Alternative splicing of SPAG5 exon3 was analyzed by RT--PCR. Results: Knockdown of SRSF3 inhibited the expression of full length SPAG5 and increased short spliced product of SPAG5 in CAL27 cells. Conclusion: SRSF3 could down--regulate the expression of SPAG5 protein and interfere with mitosis in OSCC.
