Geniposide, derived from Gardenia jasminoides Ellis, shows anti-tumor effect against multiple cancers. This study investigates the role of geniposide in migration and angiogenesis of NSCLC cells. Geniposide reduces NSCLC cell proliferation, migration, and angiogenesis, possibly through regulation of PPARγ/VEGF-A pathway.
Geniposide, an iridoid glycoside derived from traditional Chinese herb, Gardenia jasminoides Ellis, exerts antitumor effect against distinct cancers. The role of geniposide in the migration and angiogenesis of non-small cell lung cancer (NSCLC) cell was investigated in this study. Cancer cells were incubated with various concentrations of geniposide, and proliferative ability was detected by Cell Counting Kit-8 (CCK-8) and 5-ethynyl-2'-deoxyuridine (EdU) staining. Wound healing and transwell were used to assess cell migration and invasion, respectively. Tube formation assay was performed to investigate angiogenesis. Geniposide reduced NSCLC cell proliferation, and suppressed NSCLC cell migration and invasion in a dosage-dependent manner. Angiogenesis of NSCLC was also inhibited by geniposide. Geniposide increased the protein expression of peroxisome proliferator-activated receptor gamma (PPAR gamma) and decreased vascular endothelial growth factor-A (VEGF-A) protein expression in NSCLC cells. Incubation with a PPAR gamma antagonist, GW9662, attenuated geniposide-induced up-regulation of PPAR gamma and down-regulation of VEGF-A. Over-expression of VEGF-A weakened geniposide-suppressed cell proliferation, migration, and angiogenesis of NSCLC. Geniposide exerted antitumor and anti-angiogenic actions on NSCLC through regulation of PPAR gamma/VEGF-A pathway.
