Nowadays, pancreatic cancer has been recognized as one of the most fatal malignancies worldwide, the molecular mechanism of which is still not fully understood. In this study, we aimed to uncover the fundamental functions of the eukaryotic translation initiation factor 3H subunit (EIF3H) in the development and progression of pancreatic cancer. Firstly, the results of immunohistochemical (IHC) staining revealed that EIF3H was highly expressed in pancreatic cancer. Moreover, lentiviruses were used to deliver shRNAs into pancreatic cancer cells for silencing EIF3H. Furthermore, the loss-of-function assays demonstrated that knockdown of EIF3H could inhibit the progression of pancreatic cancer cells by reducing proliferation capacity, promoting apoptosis, arresting cell cycle in G2 and suppressing cell migration. In summary, EIF3H may play a critical role in the development and progression of pancreatic cancer, which possesses the potential to act as a therapeutic target for pancreatic cancer treatment.
如今,胰腺癌已被公认为全球最致命的恶性肿瘤之一,但其分子机制仍未完全阐明。在这项研究中,我们旨在揭示真核翻译起始因子 3H 亚基(EIF3H)在胰腺癌发生和发展中的基本功能。首先,免疫组织化学(IHC)染色的结果表明 EIF3H 在胰腺癌中高表达。此外,我们还使用慢病毒将 shRNAs 递送至胰腺癌细胞中以沉默 EIF3H。此外,功能丧失实验表明,EIF3H 的敲低通过降低增殖能力、促进细胞凋亡、将细胞周期阻滞在 G2 期以及抑制细胞迁移,从而抑制了胰腺癌细胞的进展。综上所述,EIF3H 可能在胰腺癌的发生和发展中发挥关键作用,有望成为胰腺癌治疗的潜在治疗靶点。
