Abstract
- The incidence rate, recurrence and metastasis rate and mortality of colorectal cancer (CRC) are high. Therefore, clinical has been looking for better treatment. Ampelopsin (AMP) has obvious inhibitory effect on some tumors. However, there is no report on the effect and mechanism of AMP on rectal cancer. To investigate the effect and mechanism of AMP on the proliferation, migration and invasion of colorectal cancer cells, at first, different concentrations of Ampelopsis japonica group (10μM, 25 μM, 50 μM), control group (without AMP), pcDNA group, pcDNA-ZFPM2-AS1 group, si-NC group, si-ZFPM2-AS1 group, miR-NC group, miR-515-5p group, AMP+pcDNA group, AMP + pcDNA-ZFPM2-AS1 group were set up. Then the expression levels of miR-515-5p and ZFPM2-AS1 were detected by QRT-PCR, protein expression was detected by Western blot, cell proliferation inhibition rate was detected by MTT method, cell invasion and migration were detected by Transwell and fluorescence activity was detected by double luciferase reporter gene assay. The results show that compared with the control group, the proliferation inhibition rate of SW480 cells in different concentrations of AMP increased and the number of migration and invasion decreased significantly. Moreover, the expression levels of CyclinD1, MMP-2 and MMP-9 were significantly lower than those in the control group, while the expression of p21 was significantly increased. The expression level of miR-515-5pin SW480 cells treated with AMP was significantly increased, while the expression level of ZFPM2-AS1 was significantly decreased. Inhibition of ZFPM2-AS1 expression or miR-515-5p overexpression could inhibit the proliferation, migration and invasion of SW480 cells and then ZFPM2-AS1 overexpression reversed the inhibitory effect of AMP on the proliferation, migration and invasion of SW480 cells. Therefore, AMP affects the proliferation, migration and invasion of colorectal cancer cells by regulating the expression of lncRNA ZFPM2-AS1/miR-515-5p, which provides a new target and new idea for the prevention and treatment of colorectal cancer.
