Downregulation of CDKL1 suppresses neuroblastoma cell proliferation, migration and invasion.

ABSTRACT:

Background

Cyclin-dependent kinase-like 1 (CDKL1) is a member of the cell division control protein 2-related serine-threonine protein kinase family. It is known to occur in various malignant tumors, but its role in neuroblastoma (NB) remains unclear.

Methods

We constructed a CDKL1-silenced NB cell strain (SH-SY5Y) and used real-time PCR and western blotting to confirm the silencing. Functional analyses were performed using the MTT, colony-formation, FACS, wound-healing and transwell invasion assays.

Results

The expression of CDKL1 was significantly upregulated in NB tissue as compared to the adjacent normal tissue. CDKL1 knockdown significantly suppressed cell viability and colony formation ability. It also induced cell cycle G0/G1 phase arrest and apoptosis, and supp
