摘要：

The secretion pattern of putuitary growth hormone (GH) in rodents is sexually dimorphic and regulates the expression of some hepatic genes. We report cloning of mouse glycine N-methyltransferase (GNMT) cDNA. The mouse GNMT mRNA is expressed at much lower levels in male than in female livers. Hypophysectomy in male mice resulted in as a high level of the expression as in female mice. Treatment with GH of hypophysectomized male mice twice a day for 5 days decreased the expression. These results indicate that the sex difference of the mouse GNMT expression is regulated by GH secretion patterns.
