I/R-induced changes of HAS2 expression in the rat small intestine myenteric plexus. (A–I) Confocal images showing co-localization of HAS2 with HuC/D in myenteric neurons of CTR animals (A–C), after I/R injury (D–F) and in the 4-MU-treated I/R group (G-I). HAS2 stained the soma of ovoid myenteric neurons. Panel J shows the percentage of myenteric neurons co-staining for HuC/D and HAS2. Bar 50 μm. ***P < 0.001 vs. CTR, ###P < 0.001 vs. sham-operated by one-way ANOVA with Tukey’s post hoc test. N = 5 rat/group. (K) mRNA levels of HAS2 in LMMP preparations obtained from the different experimental groups. Histograms show HAS2 relative gene expression determined by comparing 2−ΔΔCt values normalized to β-actin. ***P < 0.001 vs. CTR, ###P < 0.001 vs. sham-operated, §§P < 0,01 vs. I/R by one-way ANOVA with Tukey’s post hoc test. N = 5 rat/group.
