BACKGROUND: Non-small cell lung cancer is a lethal malignancy with a high
mortality rate. Deguelin displays an anti-tumor effect and inhibits metastasis in
various cancers. The aberrant expression of NIMA-related kinase 2 (NEK2)
indicates poor prognosis and induces epithelial-to-mesenchymal transition (EMT)
and metastasis processes. However, the underlying mechanism between deguelin and
NEK2 has remained elusive. METHODS: NSCLC cell lines were treated with deguelin.
Wound-healing and invasion assays were applied to study the inhibitory effect of
deguelin on NSCLC cells. EMT markers, E-cadherin and Vimentin, were also detected
by Western blot. NEK2 protein and messenger RNA expression levels were evaluated
when NSCLC cells were treated with different concentrations of deguelin. The
effect of NEK2 on NSCLC cell metastasis was evaluated through NEK2 knockdown. To
investigate whether deguelin induced EMT by regulating NEK2, we overexpressed
NEK2 in both NCI-H520 and SK-MES-1 cell lines, and then used real time-PCR to
study the E-cadherin and Vimentin messenger RNA expression in both NSCLC cells.
RESULTS: Deguelin inhibited migration and invasion processes in NSCLC cell lines
and decreased NEK2 expression in a concentration-dependent manner. Furthermore,
NEK2 knockdown inhibited NSCLC cell migration and invasion. Finally,
overexpressing NEK2 in NCI-H520 and SK-MES-1 cells could restore the inhibition
of metastasis induced by deguelin. CONCLUSIONS: Deguelin could inhibit EMT and
metastasis, while overexpression of NEK2 promotes these processes. Deguelin could
decrease NEK2 expression, while NEK2 overexpression could restore
deguelin-induced inhibition of metastasis.
