Targeting LIMK1 with luteolin inhibits the growth of lung cancer in vitro and in vivo.

ABSTRACT: Lung cancer is the leading cause of cancer-related deaths. LIM domain kinase (LIMK) 1 is a member of serine/threonine kinase family and highly expressed in various cancers. Luteolin, a polyphenolic plant flavonoid, has been reported to suppress tumour proliferation through inducing apoptosis and autophagy via MAPK activation in glioma. However, the mechanism of luteolin on suppressing lung cancer growth is still unclear. We found that luteolin targeted LIMK1 from the in silico screening and significantly inhibited the LIMK1 kinase activity, which was confirmed with pull-down binding assay and computational docking models. Treatment with luteolin inhibited lung cancer cells anchorage-independent colony growth and induced apoptosis and cell cycle arrest at G1 phase. Luteolin also decreased t
