Breed differences in the expression levels of gga-miR-222a in laying hens influenced H₂S production by regulating methionine synthase genes in gut bacteria.

ABSTRACT:

Background

The microbiota in the cecum of laying hens is crucial for host digestion, metabolism, and odor gas production. The results of recent studies have suggested that host microRNAs (miRNAs) can regulate gene expression of the gut microbiota. In the present study, the expression profiles of host-derived miRNAs in the cecal content of two laying hen breeds; Hy-line Gray and Lohmann Pink, which have dissimilar H₂S production, were characterized; and their effects on H₂S production by regulating the expression of gut microbiota-associated genes were demonstrated.

Results

The differential expression of microbial serine O-acetyltransferase, methionine synthase, aspartate aminotransferase, methionine-gamma-lyase, and adenylylsulfate kinase between the tw
