Gene expression of exocrine pancreas-specific genes. Expression of exocrine pancreas-specific genes (Cel, Cpb1, Ctrb1, Pnlip, Ppp1r3c and Amy2) in pancreatic homogenates from animals fed ad libitum (ad lib; n = 35) and exposed to rRF20 (n = 35). The data from samples collected around the clock (data shown in Fig. 3c) were pooled to compare the expression levels between both groups because none of the gene expression profile exhibited circadian variation (data not shown). Data are expressed as individual values and mean ± SEM, *P < 0.05; ***P < 0.001
