    Abstract:
    OBJECTIVE: We aimed at investigating the expression of Long non-coding RNA (LncRNA) PGM5-AS1 and its facilitating effects on proliferation and invasion of colorectal cancer by sponging miR-100-5p. PATIENTS AND METHODS: qRT-PCR was performed to detect the expressions of PGM5-AS1 and SMAD4 in human colorectal cancer tissues and cells. CCK-8 assay was performed to evaluate the SW403 cells proliferation and transwell assay was performed to evaluate the SW403 cells migration. The correlation between miR-100-5p and PGM5-AS1 was detected by statistical analysis. Bioinformatics prediction and Luciferase assay were performed to explore the interaction and binding site of PGM5-AS1 and miR-100-5p, miR-100-5p and SMAD4, respectively. RESULTS: We found that both PGM5-AS1 and SMAD4 were downregulated in human colorectal cancer tissues and cells. qRT-PCR and CCK-8 assay showed that PGM5-AS1 expression is associated with the proliferation of colorectal cancer cells. Transwell assay showed that PGM5-AS1 regulated the migration ability of colorectal cancer cells. The bioinformatics prediction and Luciferase assay demonstrated that by sponging miR-100-5p, PGM5-AS1 can serve as a molecular sponge to further regulate the expression of SMAD4. CONCLUSIONS: In this study, we found that lncRNA-PGM5-AS1 was low expressed in human colorectal cancer cells, which could promote tumor proliferation, migration and invasion by serving as a molecular sponge and by modulating the inhibitory effect of miR-100-5p on tumor suppressor gene SMAD4.
