NOS2 and lung carcinoma: We observed that both VDAC1 (Pearson’s r = 0.556, p<0.041) as well as iNOS (Pearson’s r = 0.64, p<0.016) correlated with EPOR expression and concluded that EPOR-expressing lung cancer cells showed an increased expression of iNOS and the mitochondrial marker, VDAC1 (Figure 6B).
