Abstract

HHLA2 has been recently demonstrated to play multifaceted roles in several types of cancers. However, its underlying mechanism in the progression of human ovarian cancer (OC) remains largely unexplored. In the present study, we aimed to determine whether downregulation of HHLA2 inhibited malignant phenotypes of human OC cells and explore its specific mechanism. Our results revealed that downregulation of HHLA2 by transfection with a lentiviral vector significantly suppressed the viability, invasion, and migration of OC cells. Interaction study showed that downregulation of HHLA2 in OC cells reduced the expression of CA9 and increased the expressions of p-IKKβ and p-RelA. Conversely, the viability, invasion, and migration of HHLA2-depleted OC cells were increased when CA9 was upregulated. In vivo, we found that downregulation of HHLA2 significantly inhibited tumor growth, which was reversed by CA9 overexpression. In addition, downregulation of HHLA2 inhibited the OC progression via activating the NF-κB signaling pathway and decreasing the expression of CA9. Collectively, our data suggested a link between HHLA2 and NF-κB axis in the pathogenesis of OC, and these findings might provide valuable insights into the development of novel potential therapeutic targets for OC.

下调HHLA2通过NF-κB信号通路抑制卵巢癌进展,抑制CA9的表达
HHLA2最近已被证明在几种类型的癌症中发挥多方面的作用。然而,其在人类癌症(OC)进展中的潜在机制在很大程度上尚未探索。在本研究中,我们旨在确定HHLA2的下调是否抑制人类OC细胞的恶性表型,并探讨其具体机制。我们的结果显示,通过用慢病毒载体转染下调HHLA2显著抑制OC细胞的活力、侵袭和迁移。相互作用研究表明,下调OC细胞中HHLA2可降低CA9的表达,增加p-IKKβ和p-RelA的表达。相反,当CA9上调时,HHLA2耗竭的OC细胞的活力、侵袭和迁移增加。在体内,我们发现HHLA2的下调显著抑制了肿瘤生长,而CA9的过表达逆转了这一点。此外,HHLA2的下调通过激活NF-κB信号通路和降低CA9的表达来抑制OC的进展。总之,我们的数据表明,HHLA2和NF-κB轴在OC的发病机制中存在联系,这些发现可能为开发OC的新的潜在治疗靶点提供有价值的见解。
