Figure 7. Validation of differential expression of 11 FRGs in tissues using PCR. Bar graphs show differential expression of CAPG (A), RRM2 (B), and SLC3A2 (C) was higher whereas that of SLC2A12 (D), CDO1 (E), JDP2 (F), MAFG (G), SLC2A3 (H), VDAC2 (I), GCH1 (J), and ANGPTL7 (K). * represents p-value less than 0.05, ** represents p-value less than 0.01, and *** represents p-value less than 0.001.
