Cyclophilin a knokdown inhibits cell migration and invasion through the suppression of epithelial-mesenchymal transition in colorectal cancer cells

Abstract

Enhanced expression of cyclophilin A (CypA) in colorectal cancer (CRC) was reported; however, how CypA influences CRC progression is not clear. Therefore, we examine the effects of CypA on CRC cell progression. Knockdown of CypA in SW480 cells significantly inhibited cell migration and invasion but had no effect on cell proliferation. In addition, upregulation of E-cadherin and downregulation of N-cadherin and Snail expression were observed by CypA knockdown. These results suggested that CypA knockdown inhibited cell migration and invasion by suppressing epithelial-mesenchymal transition. CypA knockdown was also associated with increased p38 phosphorylation, and the p38 inhibitor treatment led to increase in the number of invasive CypA-knockdown SW480 cells. Therefore, CypA may be a potential therapeutic target in preventing CRC metastasis.
