mRNA expression levels of the brain-derived neurotropic factor (BDNF) gene in heat-killed lactic acid bacteria (LAB) treated HT-29 cells using RT-PCR. The fold change was calculated based on normalization with GAPDH gene expression. Control group was treated with PBS. L. rhamnosus GG, heat-killed L. rhamnosus GG; L. fermentum 200060, heat-killed L. fermentum KU200060; L. delbrueckii 200171, heat-killed L. delbrueckii KU200171; and L. buchneri 200793, heat-killed L. buchneri KU200793. All values are expressed as mean ± standard error of triplicate experiments. Different superscript letters on each bar represent significant differences (p < 0.05).
