Figure 2: (a) qRT-PCR analysis of Mmp2, Bhlhb9, Fn1, and Src mRNA expression normalized to Gapdh in Dunn and LM8 cells. For comparison the fold-change values calculated from the microarray data are indicated above the graph. (b) Representative western blots of MMP2 protein levels in FCS-free supernatant of Dunn and LM8 cells and (c) quantitative analysis of three independent western blots experiments. Results are shown as the means ± SEM.
