Project description:Animal nutrition considerably affects milk composition that influences its nutritional quality. Milk component synthesis and secretion by the mammary gland involve the expression of a large number of genes whose nutritional regulation remains poorly defined. In this study, 16 lactating goats received 4 experimental diets differing in either forage to concentrate ratio (high forage, HF, or low forage, LF) supplemented, or not, with lipids (whole rapeseeds, RS, or sunflower oil, SO) in a 4 x 4 Latin Square design. To investigate the pathways regulated by nutrition, we examined the effect of these diets on the expression of approximately 8400 genes in caprine mammary gland using a bovine oligonucleotide microarray.

To investigate the pathways regulated by nutrition, we examined the effect of these diets on the expression of approximately 8400 genes in caprine mammary gland using a bovine oligonucleotide microarray. Due to the limited quantity of mammary RNA available, equal amounts of total RNA sample from mammary gland of each goat belonging to the same Latin Square group were mixed together before labeling. Each mammary pooled sample (4 by dietary treatment) was then co-hybridized with a standard reference corresponding to a mixture of purified total RNA from several caprine tissues. Each hybridization was repeated in a dye-swap manner for a total of 32 slides (8 slides and 4 independent comparisons by dietary treatment).

Project description:In this study, we investigated the molecular regulatory mechanisms of milk protein production in dairy cows by studying the miRNAomes of five key metabolic tissues involved in protein synthesis and metabolism from dairy cows fed high- and low-quality diets. In total, 340, 338, 337, 330, and 328 miRNAs were expressed in the rumen, duodenum, jejunum, liver, and mammary gland tissues, respectively. Some miRNAs were highly correlated with feed and nitrogen efficiency, with target genes involved in transportation and phosphorylation of amino acid (AA). Additionally, low-quality forage diets (corn stover and rice straw) influenced the expression of feed and nitrogen efficiency-associated miRNAs such as miR-99b in rumen, miR-2336 in duodenum, miR-652 in jejunum, miR-1 in liver, and miR-181a in mammary gland. Ruminal miR-21-3p and liver miR-2285f were predicted to regulate AA transportation by targeting ATP1A2 and SLC7A8, respectively. Furthermore, bovine-specific miRNAs regulated the proliferation and morphology of rumen epithelium, as well as the metabolism of liver lipids and branched-chain AAs, revealing bovine-specific mechanisms. Our results suggest that miRNAs expressed in these five tissues play roles in regulating transportation of AA for downstream milk production, which is an important mechanism that may be associated with low milk protein under lowquality forage feed.
