The increased hepatic MT protein in diabetic rats was not associated with the metal levels, but was associated with the oxidative damage.

TBI in rats resulted in lower levels of MT1 and MT2; replication of these findings is necessary as is evaluation of the consequences of lower receptor levels.
Title: Brain injury results in lower levels of melatonin receptors subtypes MT1 and MT2.
Although,there is induction of metallothionein due to arsenic toxicity, the sequestration of arsenic(III) ions by metallothionein was not observed. Therefore, it can be concluded that the sequestration of arsenic by metallothionein in liver is not the mechanism for providing protection in case of acute arsenic toxicity unlike cadmium and other toxic heavy elements.

An inhibitory effect of melatonin on oxytocin secretion from the rat hypothalamo-neurohypophysial system is mediated through a subtype MT1 membrane receptor and its action is independent of subtype MT2 receptor. However, for the stimulatory effect of pharmacological concentration of the pineal hormone on oxytocin release, probably mechanisms other than membrane MT1/MT2 receptor(s)-dependent are involved.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
