目的 甲状腺激素 (TH) 在垂体功能中发挥重要作用。它们调节垂体前叶激素的分泌,也是垂体细胞增殖和分化的关键决定因素。脱碘酶作为 TH 作用的前受体调节剂,其关键作用在很大程度上仍未被探索。三种脱碘酶代谢活性和非活性 TH,从而确定生物活性配体三碘甲腺原氨酸 (T3) 的组织浓度。我们假设垂体肿瘤中脱碘酶的异常表达和/或酶活性的改变可能会改变 TH 的组织浓度并影响其生长和分泌特性。
objective Thyroid hormones (THs) perform essential roles in pituitary function. They regulate anterior pituitary hormone secretion and are also key determinants of pituitary cell proliferation and differentiation. The critical role of deiodinase enzymes, which serve as prereceptor regulators of TH action, remains largely unexplored. Three deiodinase enzymes metabolize active and inactive THs and thereby determine tissue concentrations of the biologically active ligand, tri‐iodothyronine (T3). We hypothesized that aberrant expression of deiodinase enzymes and/or altered enzyme activity in pituitary tumours may change tissue concentrations of THs and influence their growth and secretory characteristics.
