宫颈癌是妇女癌症的第三大常见原因,在临床治疗方面具有重大挑战。人乳头瘤病毒(HPV)是宫颈癌的主要病因。在这里,我们发现异质核核糖核蛋白A1 (HNRNPA1)在hpv相关宫颈癌细胞(包括HeLa, Caski和SiHa细胞)中的表达水平升高,特别是在HeLa细胞中。我们提供的证据表明,HNRNPA1的表达与HeLa细胞的增殖、侵袭和迁移密切相关。新出现的证据表明,组蛋白修饰可以解释基因表达。此外,我们的研究结果表明,HNRNPA1可以通过p300介导的赖氨酸巴丁酰化被p300调节。抑制p300可下调赖氨酸巴丁酰化水平和HNRNPA1的表达。p300介导的赖氨酸巴丁酰化参与HNRNPA1对HeLa细胞增殖、侵袭和迁移的调控。总之,我们的研究发现p300介导的赖氨酸巴丁酰化可以增强HNRNPA1的表达,从而促进HeLa细胞的增殖、侵袭和迁移。
Cervical carcinoma is the third most common cause of cancer in women with a significant challenge in clinical treatment. Human papillomavirus (HPV) is strongly responsible for cervical carcinoma. Here, we show the increased expression level of heterogeneous nuclear ribonucleoprotein A1 (HNRNPA1) in HPV-associated cervical cancer cells including HeLa, Caski, and SiHa cells, especially in HeLa cells. We provide the evidence that the expression of HNRNPA1 is closely related to HeLa cell proliferation, invasion, and migration. Emerging evidence show that histone modifications account for gene expression. Moreover, our results indicate that HNRNPA1 could be regulated by p300 through p300-mediated lysine crotonylation. Inhibition of p300 downregulated both the lysine crotonylation level and the HNRNPA1 expression. And p300-mediated lysine crotonylation participates in the regulation of HNRNPA1 on HeLa cell proliferation, invasion, and migration. Collectively, our study uncovers that p300-mediated lysine crotonylation enhances expression of HNRNPA1 to promote the proliferation, invasion, and migration of HeLa cells.
