Fig. 1From: Breed differences in the expression levels of gga-miR-222a in laying hens influenced H2S production by regulating methionine synthase genes in gut bacteriaMorphological characteristics of exosomes and significantly expressed miRNAs. Morphological characteristics of exosomes in Lohmann cecal contents (A) and in Hy-line cecal contents (B). White arrows indicate exosomes. C Ten differentially expressed miRNAs between the two breeds. Asterisk indicates a significant difference in an miRNA between the two breeds, and significant differences between the means were determined by Tukey’s test. Differences were considered significant at P < 0.05, and the bar graph in C shows the expression level of these 10 miRNAs. The bars on the “0” X axis indicate upregulation in the Hy-line hens compared to the Lohmann hens, and the bars under the “0” X axis indicate downregulation in the Hy-line hens compared to the Lohmann hensBack to article page
