Background: LncRNAs are found to be aberrantly expressed in human cancers and could function as potential oncogenes or tumor suppressor genes. LINC00265 is a newly discovered LncRNA and its function in colorectal cancer (CRC) remains unknown. Methods: Comprehensive bioinformatics analysis were performed to investigate the expression, clinical significance and potential biologic functions of LINC00265 in CRC based on the data from the Cancer Genome Atlas (TCGA). To further investigate the potential role of LINC00265 in CRC, we knocked down the LINC00265 expression in HT29 cells. The cell proliferation, invasion, cycle distribution, and apoptosis were evaluated in control, NC and siRNA groups. Additionally, effect of LINC00265 on the expression of EGFR was also measured. Results: The expression level of LINC00265 is increased in CRC tissues. Elevated level of LINC00265 is correlated with lymph node metastases and advanced pathological stage. We obtained 269 LINC00265 related genes; the results of functional analysis of these genes revealed that LINC00265 might involve in carcinogenesis of CRC. In addition, further experiments indicated that LINC00265 knockdown impaired cell proliferation and invasion, promoted cell cycle distribution and apoptosis in HT29 cells. Moreover, Western blot analysis revealed that downregulation of LINC00265 suppressed the expression of EGFR. Conclusion: Our results indicate that LINC00265 induces cell proliferation, migration and inhibits CRC cells apoptosis by targeting EGFR. LINC00265 could be served as a diagnostic factor and therapeutic target for CRC patients.
