Abstract:Objective: To explore the role and possible mechanism of CIAPIN1 in bladder urothelial carcinoma. Methods: Bladder urothelial cancer cell lines J82, T24, UM-UC-3 and human bladder epithelial immortalized cells SV-HUC-1 were used as the research objects. qRT-PCR was used to detect the expression level of CIAPIN1 mRNA in the cells; Western blot was used to detect the expression levels of CIAPIN1 p-ERK1/2 and ERK1/2 protein in cells; 5-ethynyl-2'-deoxyuridine (EdU) labeling test was used to detect cell proliferation; cell scratch test was used to detect cell migration; Transwell test was used to detect cell invasion. Results: Compared with SV-HUC-1 group, the expression levels of CIAPIN1 mRNA and protein in cells of T24, UM-UC-3 and J82 groups were significantly increased (P<0.05). Cells in T24 group had the most obvious changes, so T24 cells were selected for subsequent experiments. Compared with the NC group, the number of EdU-positive cells, cell migration distance, and invasive cells in the si-CIAPIN1 group were significantly reduced (P<0.05), and protein expression level of p-ERK1/2/ERK1/2 was significantly increased (P<0.05) ; Compared with the si-CIAPIN1 group, the number of EdU positive cells, migration distance, and number of invasive cells in the si-CIAPIN1+ U0126 group were significantly increased (P<0.05), and the protein expression level of p-ERK1/2 / ERK1/2 was significantly reduced ( P<0.05). Conclusion: CIAPIN1 promotes the proliferation and metastasis of bladder urothelial cancer cells by inhibiting ERK1/2 pathway phosphorylation.
