This study investigated the receptor mechanism(s) by which the hormone melatonin directly affects ovarian function. Expression of MT1 and MT2 melatonin receptor mRNA was detected in the rat ovaries both by reverse transcriptase-polymerase chain reaction and in situ hybridization with digoxigenin-labeled oligoprobes. Specific 2-[125I]iodomelatonin binding(More)
This study assessed the state of melatonin MT(1) receptor coupling in sections of male rat caudal arteries by [35S]GTPgammaS binding autoradiography. The melatonin MT(1) receptor inverse agonist 4-phenyl-2-propionamidotetraline (4P-PDOT) (0.1-1 microM) significantly decreased [35S]GTPgammaS binding compared to basal, strongly suggesting the presence of(More)
In rat caudal artery, contraction to melatonin results primarily from activation of MT(1) melatonin receptors; however, the role of MT(2) melatonin receptors in vascular responses is controversial. We examined and compared the expression and function of MT(2) receptors with that of MT(1) receptors in male rat caudal artery. MT(1) and MT(2) melatonin(More)
Tumors or chronic inflammatory lesions of the occipital condyle may cause occipital pain associated with an ipsilateral hypoglossal nerve injury (occipital condyle syndrome). We describe a young woman with recurrent otitis media and occipital condyle syndrome associated with a limited form of Wegener's disease.
