Identification of melatonin receptor in human embryonic peripheral tissue / 第二军医大学学报

@#Objective: To determine protein binding characteri stic and signal transmission pathway of melatonin（Mel） receptor(MR) in human e mbryonic peripheral organ tissues. Methods: MR was measured by radio ligand-binding assay and the effect of GTPγS on melatonin specific bindi ng was studied. Results: Mel specific binding sites were det ermined in 16 kinds of human embryonic tissue and this binding could be inhibit ed by GTPγS, supporting the theory that MR is coupled to inhibitory G-proteins system. Conclusion: MR is measured in human embryo tissue, the se results provide experimental data for elucidating the mechanism of the effect of Mel.

Immunohistochemical detection of melatonin receptor subtype in the adrenal corte x of the human embryo / 第二军医大学学报

@#Objective: To investigate the potential role of me latonin in the adrenal cortex of human embryo. Methods:Specifi c melatonin receptors was localized and characterized in the adrenal cortex of h u man embryo by means of immunohistochemistry. Results: mt1 （Me l1a）and MT2 （Mel1b）subtype of melatonin receptors was principally localize d to cytoplasm in zona glomerulosa， fasciculata and reticularis. Conclu sion: It is possible that mt1 and MT2 subtype of melatonin receptors co-exist in the adrenal cortex of human embryo.

Detecting melatonin receptor in thyroid of human embryo with immunohistochemistr y and in situ hybridization / 第二军医大学学报

Objective: To make it clear whether there exists m elatonin receptor in the thyroid of human embryo. Methods: Thyr oid was collected and sliced up to be stained with methods of immunohistochemis try and in situ hybridization. Results: The thyroid tissue w as p ositively dyed, melatonin receptor mt1 and MT2 were with both immunohistoche mistry and in situ hybridization while brown granules dep osited in the membrane, plasma and nuclear of the thyroid cell were with the imm unohitochemistry. Conclusion: There exists melatonin rece ptors in human embryo thyroid, either mt1 or MT2, and they exist in the memb rane, plasma and nuclear.
