Accordingly, when we analyzed the paired tumor/adjacent normal adrenal samples, livin was consistently higher in tumors (in both ACC and ACA) than in adjacent adrenal tissues (0.101 ± 0.131 vs 0.008 ± 0.016 and 0.001 ± 0.002 vs 0.0003 ± 0.0018 in ACC and ACA vs adjacent NAG, respectively; Figure 1B and 1C). This evidence concerns the gene BIRC7 and adrenal cortex carcinoma.
