Fig. 3From: GABA selectively increases mucin-1 expression in isolated pig jejunumRelative expression levels of mucin-1 mRNA in buffer control and in GABA- or glutamine-treated jejunum tissue samples. Original data were normalized to beta-2 microglobulin and beta-actin and were calibrated to the mean of the control group. Box plots show 25/75 percentiles and medians. Asterisks indicate statistically significant differences between treatment and control (P < 0.05). n = 9Back to article page
