doi: 10.3390/ijms242417528
Figure Lengend Snippet: Figure 7. Downregulation of paxillin by OFD1 knockdown inhibits melanocyte adhesion to the ECM. (a,b) Adhesion assays performed on fibronectin or type IV collagen-coated culture dishes with immunofluorescent microscopy for nuclei (a) or mCherry (b) using cultured melanocytes with control RNA (control sgRNA) or OFD1 knockdown (OFD1 sgRNA) in the presence (paxillin) or absence (mock vector) of mCherry-fused PXN overexpression or nontransfected control (−vector), and cells with mCherry-fused PXN overexpression (bar = 0.05 mm). (c) Western blot analysis of the relative ratios of paxillin, FAK, and integrin β1 in cultured melanocytes with or without OFD1 knockdown in the presence or absence of PXN overexpression. (d,e) Adhesion assay performed on fibronectin- or type IV collagen-coated culture dishes using cultured melanocytes with control sgRNA or PXN knockdown (PXN sgRNA) (d) and cells with IFT88 knockdown (IFT88 sgRNA) (e). β-actin was used as an internal control in the Western blot analysis. The nuclei for immunofluorescence staining were stained with Hoechst 33,258 (bar = 0.05 mm). The data from cultured melanocytes in each graph represent the mean ± SDs of six independent experiments. * p < 0.05 and ** p < 0.01 vs. control, # p < 0.05 and ## p < 0.01 vs. sample without PXN overexpression.
