Colorectal cancer (CRC) is a common cancer and the function of long noncoding RNA (lncRNA) AB073614 in CRC mainly unclear. Here, the expression of lncRNA AB073614 in CRC tissues was evaluated by quantitative real-time PCR (qRT-PCR). CCK-8 assays were conducted to explore the impact of AB073614 on cell proliferation. The effects of AB073614 on cell migration, invasion and apoptosis were evaluated by a Transwell in vitro assay. Apoptosis-related molecular marker expression levels were detected by Western blot analysis. In the present study, we confirmed that AB073614 was significantly upregulated in CRC tissues. A difference analysis in the lncRNA AB073614 expression in CRC patient group suggested that the expression of lncRNA AB073614 was independently associated with higher possibilities of high grade (P = 0.0005), tumor size (> 5 cm) (P = 0.0001), distant metastasis (P = 0.0009), and differentiation level (P = 0.0037). In vitro studies demonstrated that the knockdown of {“type”: “entrez-nucleotide”, “attrs”:{“text”: “AB073614”, “term_id”: “51555790”, “term_text”: “AB073614”}}AB073614 suppressed SW480 cell proliferation. Meanwhile, the overexpression of {“type”: “entrez-nucleotide”, “attrs”:{“text”: “AB073614”, “term_id”: “51555790”, “term_text”: “AB073614”}}AB073614 in SW480 cells accelerated cell growth and invasion, and suppressed cell apoptosis. In conclusion, our results suggest that AB073614 may function as a tumor promoter in CRC. Our findings may provide a therapeutic approach for the future treatment of CRC. |
