Effect of L. plantarum C88 on decreased apoptosis of liver. a The levels of Bax, Bcl-2 and Caspase-3 in liver were measured. b FAS, FADD, TRADD and Caspase-8 gene expression was measured by RT-PCR. c Expression of FAS, FADD, TRADD, Caspase-8 and β-actin was detected by Western blot analysis. β-actin was used as a housekeeping control. d DNA was extracted and analyzed by agarose gel electrophoresis to analyze the DNA fragmentation. The different letters in the same rows mean significant difference (P < 0.05), the same letters in the same rows mean insignificant difference (P > 0.05).
