Temporal expression patterns of GHSR/ghrelin during acute colitis induced by DSS. C57/BL6 mice were given 2% DSS aqueous solution instead of normal drinking water for 7 days. Mice were sacrificed at day 0, 3, 7 and 11; colons, MLNs and spleens were harvested for gene expression analysis. The RNA levels of GHSR (A) and ghrelin (B) were quantified by rRT-PCR. Each point represents the mean ± SEM; *p < 0.05 and **p < 0.01.
