Tumor volume, SUVmax and SUVmean were significantly higher in lesions with high PBK protein expression (p≤0.03 for all; Supplementary Table 5) and PBK mRNA expression was significantly anti-correlated to ADC value in low grade endometrial cancer and CAH (p=0.03, data not shown). The gene discussed is PBK; the disease is congenital adrenal hyperplasia.
