**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.
