Figure Lengend Snippet: A Immunofluorescence staining of Foxq1,EGFR,VE-cadherin,MMP2, and MMP9 in Foxq1 dysregulated 5–8F, and CNE1; Scale bars represent 50 μm. qRT-PCR (above) and western blot (down) were used to monitor the expression of EGFR signaling pathway and VM-related genes in 5–8F, and CNE1 after Foxq1 downregulation ( B , C ) or overexpression ( D , E ). F The binding motif of Foxq1 from the JASPAR database. G A diagram showing the relationship of full-length (FL) and mutant EGFR promoters. H 293 T cells were transfected with Foxq1 overexpressing or control vector. The luciferase reporter gene vectors carrying FL or EGFR promoter mutant were co-transfected respectively for 36 h. Then, the dual-luciferase activity was detected. I The CHIP-PCR assay was used to assess the binding of Foxq1 to the EGFR promoter region. J Anti-Foxq1-pulled down chromatins were analyzed by qRT-PCR. Data are presented as mean ± SD of three independent experiments.
Article Snippet: The membrane was incubated with polyclonal antibodies against EGFR (AF6043, Affinity, China), phospho-EGFR (AF3047, Affinity, China), MMP2 (AF0577, Affinity, China), MMP9 ( AF5228 , Affinity, China), VE-Cadherin (AF6265, Affinity, China), AKT (bsm-33282M, Bioss, China), phospho-AKT (bs-0876R, Bioss, China), Foxq1 (PA1-31951, Invitrogen, USA) or GAPDH (AC033, Abclonal, China) at a dilution of 1:1000, then incubated with species-specific HRP-conjugated secondary antibodies at a dilution of 1:5000.
