In order to investigate whether the effects of HQS, RP, or RA on the depressed liver energy and cholestasis were related to the expressions of CFTR and α-ENaC, we used real-time RT-PCR analysis to examine the expression levels of CFTR and α-ENaC in liver, pancreas, and colon (Figures 1(c)–1(e)). Here, CFTR is linked to cholestasis.
