Purpose:
Cofilin 1 is a type of cytoskeletal protein. The overexpression of this gene has been regarded to hold a special relationship with the development and progress of some cancers. However, the detailed position of Cofilin 1 in human bladder cancer has not been investigated intensively.
Methods:
In this study, we mainly explored the relationship between human bladder cancer and the expression of Cofilin 1. The expression of Cofilin 1 in bladder cancer tissues and paracancerous tissues of patients was evaluated with quantitative polymerase chain reaction, Western blot, and immunohistochemical staining. Downregulation of Cofilin 1 expression model was established with siRNA in human RT4 bladder cancer cell line, and the changing cell viability was analyzed to determine the role of Cofilin 1 in human bladder cancer.
Results:
Our results showed that the expression of Cofilin 1 was much higher in both RNA level and protein level in human bladder cancer tissues than paracancerous tissues for 3 patients. Downregulation of Cofilin 1 expression could inhibit cell proliferation, cell migration, cell adhesion, and colony formation ability, and increase the percentage of cell apoptosis in RT4 cells.
Conclusions:
Our study indicates that Cofilin 1 holds an important position in the development and progression of human bladder cancer, and this gene might become a novel target in the diagnosis and treatment of human bladder cancer.
