Expression levels of cell proliferation marker genes following the HCl/ethanol treatment. Total RNA was extracted from the stomachs of mice subjected to HCl/ethanol treatment and analyzed by quantitative RT-PCR for expression of c-fos and c-myc genes, general markers for cell proliferation. Mean values±s.e.m. at each time point for c-fos gene (a) and c-myc gene (b), normalized to the internal references (β-actin). N=6 pairs per time point. *P<0.05.
