人乳头瘤病毒(HPV)感染是发生宫颈癌的先决条件,其中大约一半与HPV 16型有关。HPV 16编码三种癌基因:E5、E6和E7,其中E5迄今为止研究最少。它在调节 HPV 复制和发病机制中的作用尚不完全清楚。在这里,我们利用高通量筛选来协调研究E5对宿主蛋白编码和microRNA基因表达的影响。 MicroRNA 形成一类具有调节活性的 22nt 长非编码 RNA。在改变的细胞 microRNA 中,我们重点关注 E5 诱导 96 小时的时间间隔内 miR-146a、miR-203 和 miR-324-5p 及其靶基因表达的变化。我们的结果表明,HPV 感染和随后的转化是通过宿主细胞中基因表达的复杂调控模式发生的,其中部分是由 E5 蛋白调控的。
Human papillomavirus (HPV) infection is a prerequisite of developing cervical cancer, approximately half of which are associated with HPV type 16. HPV 16 encodes three oncogenes, E5, E6, and E7, of which E5 is the least studied so far. Its roles in regulating replication and pathogenesis of HPV are not fully understood. Here we utilize high-throughput screening to coordinately investigate the effect of E5 on the expression of host protein-coding and microRNA genes. MicroRNAs form a class of 22nt long noncoding RNAs with regulatory activity. Among the altered cellular microRNAs we focus on the alteration in the expression of miR-146a, miR-203 and miR-324-5p and their target genes in a time interval of 96 hours of E5 induction. Our results indicate that HPV infection and subsequent transformation take place through complex regulatory patterns of gene expression in the host cells, part of which are regulated by the E5 protein.
