In addition, the serum FABP4 level was significantly higher (P=0.022; Figure 5D) in patients with advanced pathological T (pT) PCa stage (≥ pT3; 18.2 ± 10.1 ng ml-1; n=34) compared with those with a more localized disease (≤ pT2; 15.8 ± 3.7 ng ml-1; n=70). Here, FABP4 is linked to glycogen storage disease VI.
