... profiles of HO-1 and HO-2 in eight human cell lines by northern and western blot analyses (Fig. 1A,B). Expression of HO-1 mRNA was detected in five of these cell lines, but hardly at all in the other ... contrast, HO-2 mRNA and protein were both expressed in all eight cell lines (Fig. 1A,B). We also measured the heme content of these cell lines: it was about twofold higher in YN-1 and K56...
