Wilcoxon rank-sum tests (two-sided) with Bonferroni-Holm’s correction were applied to panels ad. Data in bar graphs are medians ± 25th and 75th percentiles; Boxplots present medians as dots, interquartile boxes from 25th to 75th percentile, whiskers from smallest to largest values; *P < 0.05; n.s not significant.
