ROLE of THYROID HORMONE in MOUSE INTESTINAL DEVELOPMENT and REGENERATION.
Thyroid hormone (T3) is known to be critical for postembryonic development in mammals (around birth). This laboratory has been taking a multi-faceted approach to investigate the function of T3 and T3 receptors (TRs) in vivo by using Xenopus and mouse as models. A major recent focus is on how T3 regulates adult stem cell function during mouse postembryonic intestinal maturation and regeneration. We have shown earlier that System L amino acid transporter can influence gene regulation by TR through cellular uptake of T3 in a cell line and frog occytes. In addition, the TR coactivator PRMT1 is upregulated during mouse intestinal maturation. Yun-Bo Shi is recruiting two postdoctoral fellows to use knockout mice to study whether they play a role in the function of T3 in the intestinal maturation and regeneration.
