BNIP3 and skin basal cell carcinoma: In BCC, significant correlations between CAIX and GLUT1 (r = 0·369, P = 0·024), CAIX and pS6 (r = 0·522, P = 0·001) and CAIX and PHD2 (r = 0·426, P = 0·007) were detected as well as between PHD2 and BNIP3 (r = 0·485, P = 0·003) and PHD2 and pS6 (r = 0·399, P = 0·012).
