Fig. 4From: Lactobacillus paracasei and Lactobacillus plantarum strains downregulate proinflammatory genes in an ex vivo system of cultured human colonic mucosaValidation of microarray data. qPCR results (black bars) of selected genes using total RNA from colonic explants (pooled data of samples from 3 patients used in microarray hybridizations (RSL-6, RSL-10 and RSL-21)) and comparison with microarray data (gray bars). Fold changes are calculated relative to Control tissue and normalized to B2M expression. Expression values of each individual patient obtained by qPCR and microarray hybridization are shown in Online Resource 3Back to article page
