Summary: | Exploring the roles of long noncoding RNAs (lncRNAs) in tumorigenesis and metastasis could contribute to the recognition of novel diagnostic and therapeutic targets. LINC02870 is a novel lncRNA, whose role in tumors has not been reported. Herein, we focused on the function and mechanism of LINC02870 in human hepatocellular carcinoma (HCC). We first carried out a pan-cancer study of LINC02870 expression and its relationship to prognosis, and LINC02870 was determined to be a possible oncogene in HCC. Upregulated expressions of LINC02870 were also found in our HCC samples compared to the para-tumor samples. Moreover, overexpression of LINC02870 promoted the growth, migration, and invasion of HCC cells. Subsequently, binding proteins of LINC02870 were identified by a number of in silico analyses, including correlation analysis, signaling network analysis, and survival analysis. Intriguingly, the most promising binding protein of LINC02870 was predicted and confirmed to be eukaryotic translation initiation factor 4 gamma 1 (EIF4G1), an important component of the eukaryotic translation initiation factor 4F complex that initiates cap-dependent translation. Further investigation showed that LINC02870 increased the translation of SNAIL to induce malignant phenotypes in HCC cells. Additionally, HCC patients with higher expression levels of LINC02870 and EIF4G1 had shorter survival times than those with lower expression levels. Thus, our findings suggested that LINC02870 induced SNAIL translation and correlated with poor prognosis and tumor progression in HCC. |
