RESUMEN
Aim To explore the effects of the expression of the transcription faetor Glil of Hedgehog ( Hh ) signaling pathway and the 6-Shogaol mediated Hedge- hog/Glil pathway on the proliferation, invasion and migration in MDA-MB-231 eells of triple negative breast eaneer.Methods MDA-MB-231 eells were transfected by lentiviral vectors to stably overexpressed Glil gene.The overexpression efficiency of Glil was verified by qRT-PCR and Western blot.CCK-8 and EdlJ assays were used to detect the effect of Glil expression and 6-Shogaol on cell viability.Cell scratch assay and Transwell assay were used to detect the ability of migration and invasion.Western blot was used to detect the proteins expression of Hedgehog signaling pathway and other related genes.Results MDA-MB- 231-Glil overexpression cell line was successfully established.When Gli 1 gene was overexpressed, the invasion and migration ability of cells was significantly improved, anrl the expression of Hh signaling pathway gene Glil , EMT marker gene Vimentin, Hippo signaling pathway genes YAP and TEAD4 inereased.When the expression of Glil was inhibited by the Hh/Gli pathway inhibitor Gant61 , the proliferation, invasion and migration abilities were suppressed.When the eells were treated with 6-Shogaol, the abilities of proliferation, invasion and migration were inhibited as well as the proteins expression of Glil , Vimentin, YAP and TEAD4 deereased.Conclusions Glil gene ean promote the invasion and migration of MDA-MB-231 eells.6-Shogaol ean inhibit proliferation, invasion and migration of breast eaneer eells through Hedgehog signaling pathway, suggesting that transcription factor Glil may be one of the targets of 6-Shogaol.
