EPOR and squamous cell carcinoma: When we analyzed biopsies of lung cancer patient subgroups, we found that EPOR positively correlated with VDAC1 expression in human adenocarcinoma lung tumors (Pearson’s r = 0.4568, p<0.0001) as well as in human squamous cell carcinoma lung tumors (Pearson’s r = 0.553, p<0.0001), while no correlation was found in human large cell carcinoma biopsies (Figure 6D).
