Primary liver cancer, specifically hepatocellular carcinoma (HCC), is a major global health concern. GCNT3 has been identified as an oncogene in various human malignancies. This investigation aimed to discover the GCNT3 function in HCC. The present study employed integrated bioinformatics analyses to assess the expression pattern, prognostic implications, and putative function of GCNT3 in HCC. Transwell flow cytometry, CCK-8, and wound healing assays were performed to examine HCC cell growth, cell cycle, apoptosis, invasion, and migration. In addition, the epithelial-mesenchymal transition (EMT) markers and PI3K/AKT mechanism markers were examined via western blot analysis to elucidate the underlying mechanisms. In HCC, GCNT3 was significantly overexpressed, which was connected with enhanced tumor aggressiveness and an unfavorable prognosis of individuals. In vitro experiments demonstrated that elevated levels of GCNT3 promoted cell growth, migration, cell cycle development, and invasion, in addition to EMT, while suppressing apoptosis. Conversely, knockdown of GCNT3 exerted the opposite effects. GCNT3 overexpression increased PI3K/AKT phosphorylation in HCC cells, and LY294002 counteracted the impacts of upregulated GCNT3 on cell cycle, migration, invasion, proliferation, and EMT in HCC. The investigation showed that GCNT3 may enhance HCC progression and EMT by stimulating PI3K/AKT mechanism.
原发性肝癌,特别是肝细胞癌(HCC),是全球主要的健康问题。GCNT3已被确定为多种人类恶性肿瘤中的一种癌基因。本研究旨在发现GCNT3在肝癌中的功能。本研究采用综合生物信息学分析方法,评估GCNT3在肝癌中的表达模式、预后意义及潜在功能。通过Transwell实验、流式细胞术、CCK-8实验和伤口愈合实验检测肝癌细胞的生长、细胞周期、凋亡、侵袭和迁移情况。此外,通过蛋白质免疫印迹分析检测上皮-间质转化(EMT)标志物和PI3K/AKT信号通路相关标志物,以阐明其潜在机制。在肝癌中,GCNT3显著高表达,这与肿瘤侵袭性增强及患者预后不良相关。体外实验表明,GCNT3水平升高促进细胞生长、迁移、细胞周期进展和侵袭,同时抑制凋亡,此外还促进EMT;相反,敲低GCNT3则产生相反的效果。GCNT3过表达增加肝癌细胞中PI3K/AKT的磷酸化水平,而LY294002可抵消GCNT3上调对肝癌细胞周期、迁移、侵袭、增殖和EMT的影响。研究表明,GCNT3可能通过激活PI3K/AKT信号通路促进肝癌进展和EMT。
