title: Knockdown of PFTAIRE Protein Kinase 1 (PFTK1) Inhibits Proliferation, Invasion, and EMT in Colon Cancer Cells.
abstract: PFTK1 is a member of the cyclin-dependent kinase (CDK) family and is upregulated in many types of tumors. However, its expression and role in colon cancer remain unclear. In this study, we aimed to investigate the expression and function of PFTK1 in colon cancer. Our results showed that PFTK1 was highly expressed in colon cancer cell lines. The in vitro experiments demonstrated that knockdown of PFTK1 inhibited the proliferation, migration, and invasion of colon cancer cells as well as the epithelial-to-mesenchymal transition (EMT) progress. Furthermore, knockdown of PFTK1 suppressed the expression of Shh as well as Smo, Ptc, and Gli-1 in colon cancer cells. Taken together, these results suggest that knockdown of PFTK1 inhibited the proliferation and invasion of colon cancer cells as well as the EMT progress by suppressing the Sonic hedgehog signaling pathway. Therefore, these findings reveal that PFTK1 may be a potential therapeutic target for the treatment of colon cancer.
