FABP12 and cancer: When comparing FABP expression levels (in z-scores of mRNA) based on metastatic status of cancer tissues from the same PCa patient population [44], we found 24.5x (p = 0.05), 5.2x (p < 0.001), 6.5x (p = 0.003), 2.2x (p = 0.08) and 1.7x (p = 0.09) increases in metastatic tumors compared to primary tumors for FABP12, FABP4, FABP9, FABP8 and FABP5, respectively (Figure 1D).
