Abstract:
Long noncoding RNAs lncRNAs play an essential role in the epigenetic regulation of colorectal cancer CRC. However, the biological function of lncRNA Long Intergenic Noncoding RNA 00511 LINC00511 in the CRC is unclear. Here, present research found that LINC00511 was significantly up-regulated in the CRC tissue samples and cell lines. Consistently, LINC00011 overexpression was correlated with larger tumor size and advanced tumor stage. Functionally, LINC00511 promoted the proliferation and reduced the apoptosis of CRC cells in vitro, and LINC00511 knockdown repressed tumor growth in vivo. Mechanistically, hypoxia-inducible factor 1α (HIF-1α) bound the promoter region of LINC00511 to active tits transcription. Moreover, LINC00511 functioned as the miR-153-5p sponge in the cytoplasmic portion, and miR-153-5p also targeted the 3'-UTR of HIF-1α. In conclusion, this study identifies the roles of LINC00511 in CRC progression and uncovers the positive feedback loop of HIF-1α/LINC00511/miR-153-5p in CRC, providing a potential therapeutic target.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
