Fig. 3.
mRNA expression of the BDNF gene (A), Bax gene (B), Bcl-2 gene (C), and the Bax/Bcl-2 ratio (D) in oxidatively stressed SH-SY5Y cells treated with heat-killed lactic acid bacteria–conditioned medium (LAB-CM). Oxidative stress was induced by H2O2 (50 μM). A, Lactobacillus rhamnosus GG; B, Lactobacillus delbrueckii KU200170; C, Lactobacillus plantarum KU200661; D, Lactobacillus lactis KC24. The error bars indicate standard deviations from three independent experiments. The letters on each bar exemplify significant differences (p < 0.05)
