Figure 2.
CFH and FH-L Expression in cSCC is Increased. Immunofluorescent microscopy of cells cultured from cSCC tissue show CFH staining (green) in cytosolic vesicles (A). Bands at the expected molecular weight for CFH and Factor H-like (FH-L) are detected in both adjacent normal tissue and cSCC samples (B). The ratio of CFH and FH-L band intensities, normalized to histone H3 intensity, was higher in cSCC tissue compared to ANT [(C), p=0.031 & (D), p=0.034, respectively]. In paired samples for non-invasive cSCC, CFH levels normalized to GAPDH are not significant. When CFH levels in ANT are compared to invasive cSCC, the difference is highly significant [(E), p<0.0001]. (*p<0.05; ***p=0.0001; ****p<0.0001; ns, not significant).
