MTIM affects retinal ganglion cells through PI3K/AKT signaling pathway.
Title: MTIM affects retinal ganglion cells through PI3K/AKT signaling pathway.
The increased hepatic MT protein in diabetic rats was not associated with the metal levels, but was associated with the oxidative damage.
Title: Diabetes Mellitus induces alterations in metallothionein protein expression and metal levels in the testis and liver.
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.
Title: Metallothionein does not sequester arsenic(III) ions in condition of acute arsenic toxicity.
acute attack of experimental autoimmune encephalomyelitis was followed by increased expression of metallothioneins in molecular and granular cell layer of hippocampus.

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.

After passing middle age we observe a huge increase in MT3 transcripts in both cortical and hippocampal areas, while the MT1/2 mRNA content increases slightly

The recurrent seizures plus normal diet group showed worse performances in neurological reflex tests and reduced latencies to myoclonic seizures induced by penicillin compared with the control, which was concomitant with altered expressions of ZnT-7, MT-1, MT-2, and ZIP7.

These data indicate that maternal zinc deficiency resulted in an elevated incidence of fetal heart malformations, which was associated with significant decreases in placental MT-1 and ZnT-1 mRNA expressions

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.
