[Abstract]:[objective] to observe the proliferation of human basal breast cancer cells (HCC1937) induced by minimal RNA-194 (miR-194). Migration and invasion ability and the effect of epithelial-mesenchymal transformation (EMT). [methods] using lentivirus as vector (MOIX50) carrying miR-194 sequence to infect basal breast cancer cell HCC1937 as experimental group, and carrying CON157 lentivirus to infect breast cancer cell HCC1937 as negative control group. Untreated HCC 1937 cells were blank control group. Cell proliferation ability was detected by cell count kit (CCK-8) and transwell chamber assay. Western blot assay was used to detect the expression of EMT related protein E-cadherininN-cadherin. [results] the proliferative ability of the experimental group was (44.81 鹵0.11), and the expression of EMT related protein E-cadherinn- cadherin was detected by Western Blot assay, and the cell proliferation ability of the experimental group was (44.81 鹵0.11), and that of the experimental group was (44.81 鹵0.11). It was significantly lower than that in the negative control group (104.29 鹵0.13)% and the blank control group (100 鹵0) in the Transwell chamber migration test. The number of cells on the surface of the lower ventricle in the experimental group was respectively: 1: 47 鹵2.35; in the negative control group: 94 鹵4.53; in the blank control group: 10 89 鹵5.67. In the invasion experiment, The number of cells in the subventricular surface of the experimental group was: 31 鹵1.64 in the experimental group; that in the negative control group was 65 鹵6.39; and that in the blank control group was 72 鹵2.48. The expression of E-cadherin protein in the experimental group was significantly lower than that in the negative control group and the blank control group (P0.05). The expression of E-cadherin protein in the experimental group was significantly lower than that in the negative control group (0.175 鹵0.053). The expression of N-cadherin protein in the control group (0.516 鹵0.032) and the blank control group (0.433 鹵0.047): the expression of 0.342 鹵0.012 protein in the experimental group was significantly higher than that in the negative control group (0.137 鹵0.007) and the blank control group (0.142 鹵0.021) P0.001.Conclusion MiR-194 can inhibit the proliferation of basal cell-like breast cancer cell line HCC1937. Migration and invasion ability and EMT.
