Expression of p53 is not correlated with G1 checkpoint function. A. p53 protein expression was determined by western immunoblot. Pixel intensities of p53 expression were normalized to expression of gamma-tubulin which served as a loading control. Normalized p53 expression in melanoma cell lines was expressed relative to the NHM16 culture. The immunoblot image was cropped to remove non-essential lanes. B. G1 checkpoint function in melanoma cell lines (fraction evading G1 arrest) was expressed relative to levels of expression of p53 protein (normalized pixel intensities). The Spearman correlation coefficient was 0.04, P=0.9).
