拷贝数变异(CNV)是结直肠癌(CRC)的关键驱动因素。我们以前的研究表明,蛋白质O-岩藻糖基转移酶1(POFUT 1)的过度表达是由CNVs在CRC的发展。POFUT 1在CRC中的潜在作用和潜在机制尚未研究。在这项研究中,我们分析了POFUT 1在大肠癌中的表达,从宇宙和TCGA数据库,并证实POFUT 1是高表达的大肠癌。我们使用充分表征的CRC细胞系,包括SW 620和HCT 116,以建立模型POFUT 1敲低细胞系。使用这些细胞,我们研究了POFUT 1在CRC中的作用。我们的数据显示,在CRC细胞中沉默POFUT 1抑制细胞增殖,减少细胞侵袭和迁移,阻止细胞周期进程,并刺激CRC细胞凋亡。我们进一步证明,POFUT 1沉默显着抑制CRC肿瘤的生长和体内移植。我们还揭示了POFUT 1在CRC过程中的作用的新机制,通过证明POFUT 1沉默抑制Notch 1信号传导。总之,我们的研究结果表明,POFUT 1是CRC发展过程中的肿瘤激活基因,通过激活Notch 1积极调节CRC肿瘤进展。
Copy number variations (CNVs) are key drivers of colorectal cancer (CRC). Our previous studies revealed that protein O-fucosyltransferase 1 (POFUT1) overexpression is driven by CNVs during CRC development. The potential role and underlying mechanisms of POFUT1 in CRC were not investigated. In this study, we analyzed the expression of POFUT1 in CRC from cosmic and TCGA databases and confirmed that POFUT1 is highly expressed in CRC. We used well characterized CRC cell lines, including SW620 and HCT116 to establish a model POFUT1 knockdown cell line. Using these cells, we investigated the role of POFUT1 in CRC. Our data revealed that silencing POFUT1 in CRC cells inhibits cell proliferation, decreases cell invasion and migration, arrests cell cycle progression, and stimulates CRC cell apoptosis in vitro. We further demonstrate that POFUT1 silencing dramatically suppresses CRC tumor growth and transplantation in vivo. We additionally reveal new mechanistic insights into the role of POFUT1 during CRC, through demonstrating that POFUT1 silencing inhibits Notch1 signaling. Taken together, our findings demonstrate that POFUT1 is a tumor activating gene during CRC development, which positively regulates CRC tumor progression through activating Notch1.
