Regulation of the gene expression of glucose transporter in liver and kidney of lactating cows by bovine growth hormone and bovine growth hormone-releasing factor.
Our objective was to study the effects of recombinant bovine growth hormone and bovine growth hormone-releasing factor on gene expression of glucose transporters in the liver and kidney of lactating cows. Primiparous cows received 29 mg/d of bovine growth hormone or 12 mg/d of bovine growth hormone-releasing factor by continuous intravenous infusion or no treatment (control) from 118 to 181 d postpartum. Growth hormone or growth hormone-releasing factor did not influence the mRNA abundance of the liver-type glucose transporter in the liver or kidney. Similarly, neither growth hormone-releasing factor nor growth hormone altered the mRNA abundance of the erythrocyte-type or the intestinal-type glucose transporter in the kidney, but large individual differences were observed in the mRNA abundance of the intestinal-type glucose transporter in liver.
