Expression levels of ghrelin, apoB, xpo4, pin1, penk1, and prdx2 genes by qPCR.

aThe RNAs from stomach (ghrelin, apoB, xpo4, and pin1 genes) and brain (penk1 and prdx2 genes) were analyzed for indicated genes by qPCR.
bThe ΔCT value is determined by subtracting the average CT of GAPDH from that of target gene. The standard deviation of the difference is calculated from the standard deviations of the target gene and GAPDH.
cThe calculation of ΔΔCT involves subtraction by the ΔCT calibrator value. This is a subtraction of an arbitrary constant, so the standard deviation of ΔΔCT is the same as the standard deviation of the ΔCT value.
