Figure Lengend Snippet: A) Representative WB analysis of ADAM9 and MMP7 target genes (left); cell growth proliferation analysis (right). B) WB analysis of ADAM9 and MMP7 (left), cell growth proliferation (middle) and migration (right). Actin was utilized as internal loading control.

Article Snippet: ADAM9 and MMP7 silencing was performed by using 4 unique 29-mer shRNA constructs in retroviral GFP vector, #TG314947 for ADAM9, #TG311438 for MMP7 and #TR30013 for scrambled negative control (OriGene Technologies, Rockville, MD, USA). miRCURY locked-nucleic-acid (LNA) Power Inhibitor knockdown probes for miR-126 and -126* were obtained from Exiqon (Copenhagen, Denmark), (Product numbers #426717-00 and #426718-00).

Figure Lengend Snippet: Representative Western blot of A) ADAM9, MMP7 and OPN in normal human melanocytes (NHEM) and in a panel of melanoma cell lines, B) ADAM9 isoforms (left), MMP7 and OPN (middle) and corresponding secreted forms (right) in miR-126&126* versus empty vector-transduced Me665/1 and A375M cell lines. C) Representative Real-time PCR analysis of ADAM9 (left), MMP7 (middle) and OPN (right) mRNAs in the A375M cell line. The unresponsive short isoform of ADAM9 mRNA does not carry miR-126&126* binding sites in its 3′UTR. D) Relative expression values obtained by western blot analysis of ADAM9 (left), MMP7 (middle) and OPN (right) in A375M cells transfected with oligomers mimicking mature miR-126 or miR-126* vs non targeting (no Targ); GAPDH and actin were internal loading controls in RT-PCR and WB, respectively. Columns, of a minimum of two independent experiments; ** P <0.001; * P <0.05.
