IQGAP3 interacted with GLI1 of Hedgehog pathway in lung cancer. (A) Volcano plot showing the differentially expressed genes between the IQGAP3 down-regulated H1299 cells and control group according to RNA-sequencing. (B) Heatmap showing the reduction in GLI1 expression after the knockdown of IQGAP3 in H1299 cells. (C) Validation experiments via RT-qPCR confirming mRNA expression changes in Hedgehog pathway and EMT-associated genes in A549 and H1299 cells after IQGAP3 down-regulation. (D-E) Representative images and quantified data from western blotting validating protein expression changes in Hedgehog pathway and EMT-associated genes in A549 and H1299 cells following IQGAP3 down-regulation. original blots/gels are presented in Supplementary Fig. 3 .(F) Co-immunoprecipitation assays demonstrating the interaction between endogenous IQGAP3 and GLI1 in A549 and H1299 cells. original blots/gels are presented in Supplementary Fig. 3.
