Investigate the effect of in ovo leptin administration on hepatic expression and activity of iodothyronine deiodinases, in association with early posthatch growth rate and hepatic expression of GHR and IGF-I.
Furthermore, chicken embryo hepatocytes (CEHs) were treated with leptin in vitro to reveal the direct effect of leptin on hepatic expression and activity of iodothyronine deiodinases.
