MYO5A35号外显子跳跃对头颈鳞状细胞癌患者的预后相关研究

扫码查看
目的:探讨 MYO5 A基因在头颈鳞状细胞癌(head and neck squamous cell carcinoma,HNSCC)中作为预后分子标志物的潜力.方法:从TCGA数据库下载 HNSCC队列的 RNA-Seq数据及相应的临床数据,单变量 Cox回归分析 MYO5 A与患者预后之间的关系.从TCGA SpliceSeq数据库下载 MYO5 A 基因的可变剪接类型,根据剪接百分比(percent spliced in,PSI)值识别差异性表达的MYO5 A基因的可变剪接,并分析其与 HNSCC患者预后的相关性.最后通过 RT-PCR和 Sanger测序在细胞系及徐州医科大学附属医院临床样本中进一步验证.结果:MYO5A基因在 HNSCC队列中显著高表达,但 MYO5A基因整体表达水平并不能作为独立的 HNSCC预后风险指标.MYO5A 35 号外显子跳跃在 HNSCC中发生频率增加,且与预后密切相关.MYO5A 35 号外显子跳跃在细胞系及临床样本中均得到了验证.结论:MYO5A 35 号外显子跳跃而不是 MYO5A基因整体表达水平可作为 HNSCC预后独立的分子标志物.
Prognostic Correlation Study of MYO5 A Exon 35 Skipping in Head and Neck Squamous Cell Carcinoma
Objective:To explore the potential of MYO5 A gene as a prognostic molecular marker in head and neck squamous cell carcinoma(HNSCC).Methods:RNA-Seq data and corresponding clinical data were downloaded from the TCGA database for the HNSCC queue,and the relationship between MYO5 A and patient prognosis was ana-lyzed using univariate Cox regression.The variable splicing types of the MYO5 A gene were downloaded from the TCGA SpliceSeq database,the variable splicing of the differentially expressed MYO5 A gene was identified based on the percentage spliced in(PSI)value,and its correlation with the prognosis of HNSCC patients was analyzed.Fi-nally,RT-PCR and Sanger sequencing were validated in clinical samples from cell lines and affiliated hospitals of Xuzhou Medical University.Results:The MYO5 A gene was significantly overexpressed in the HNSCC cohort,but the overall expression level of the MYO5 A gene could not be used as an independent prognostic risk indicator for HNSCC.The frequency of MYO5 A exon 35 hopping was increased in HNSCC and was closely related to prognosis.The jump of MYO5 A exon 35 was validated in both cell lines and clinical samples.Conclusion:The jump of MYO5 A exon 35 rather than the overall expression level of MYO5 A gene can serve as an independent molecular marker for the prognosis of HNSCC.
