Long non-coding RNAs (lncRNAs) are emerging as pivotal regulators in human cancer. LINC01082 was expressed as decreased in colon cancer by previous lncRNA-seq result and TCGA database, however, the role and function of LINC0182 is not clear in colon cancer. Here, we aimed to explore the role of LINC01082 in colon cancer for exploring the etiopathogenesis of colon cancer. RT-qPCR for LINC01082 expression in tissues (colon cancer vs. their matched adjacent non-cancerous tissues, ANT, n = 39) and cells (colon cancer cells vs. normal colon cells, n = 4) were performed. CCK-8 assay for proliferation of colon cancer, Transwell assay for migration and invasion were carried out in sw480 and sw620 cells. The results revealed that LINC01082 was significantly decreased in tissues and cell lines of colon cancer. Overexpressed LINC01082 significantly suppressed the proliferation ability of colon cancer cells. The migration and invasion of colon cancer cells were also suppressed after LINC01082 overexpression. These findings demonstrated that LINC01082 may act in suppressing the incidence and development of colon cancer via suppressing cell proliferation, migration and invasion, indicating that LINC01082 may act as a new tumor suppressor and may be a promising therapy target for colon cancer.
