melatonin receptor
In vitro

Melatonin interacts with the highly toxic hydroxyl radical with a rate constant equivalent to that of other highly efficient hydroxyl radical scavengers. It reportedly neutralizes hydrogen peroxide, singlet oxygen, peroxynitrite anion, nitric oxide and hypochlorous acid.

This compound is believed to scavenge the highly toxic hydroxyl radical, the peroxynitrite anion, and possibly the peroxyl radical. It reportedly scavenges the superoxide anion radical and it quenches singlet oxygen. The substance stimulates mRNA levels for superoxide dismutase and the activities of glutathione peroxidase, glutathione reductase and glucose-6-phosphate dehydrogenase (all of which are antioxidative enzymes), thereby increasing its antioxidative capacity.

This chemical in cell-free systems has been shown to directly scavenge H2O2, singlet oxygen (1O2) and nitric oxide (NO*), with little or no ability to scavenge the superoxide anion radical (O2*-) in vitro. It also directly detoxifies the peroxynitrite anion (ONOO-) and/or peroxynitrous acid (ONOOH), or the activated form of this molecule, ONOOH*. Melatonin acts as a direct free radical scavenger with the ability to detoxify both reactive oxygen and reactive nitrogen species.

It inhibits cAMP accumulation in most of the cells examined, but the indole effects on other messengers have been often observed only in one type of the cells or tissue, until now. This compound also regulates the transcription factors, namely, phosphorylation of cAMP-responsive element binding protein and expression of c-Fos.

In vivo Melatonin ameliorates necrotizing enterocolitis by preventing Th17/Treg imbalance through activation of the AMPK/SIRT1 pathway

H2O2 activates JNK through the RAC1/MAP2K7 pathway, which is inhibited by melatonin treatment. (A) GCs grown in medium containing 10 μM melatonin for 24 h were rinsed using PBS, and then incubated with 0.2 mM H2O2 for 2 h. For the inhibition of RAC1, the RAC1 specific antagonist NSC 23766 (10 μM) was added 1 h prior to H2O2 exposure. The cell lysates were collected for GST-PAK1-PBD pulldown assay of RAC1 activation (GTP-bound RAC1 levels) and immunoblotting analysis of total RAC1. (B) Western blot analysis of phosphorylated MAP2K7 (p-MAP2K7) and total MAP2K7 in GCs with the indicated treatments as described above. TUBA1A served as the control for loading. (C) The detection of JNK activity in GCs subjected to the treatments as mentioned earlier. Data represent mean ± s.e.; n = 3. **Represents P < 0.01 vs control group. ##Represents P < 0.01 vs H2O2 group. N, not significant, P > 0.05. (D) GCs transfected with scrambled control siRNA (SC siRNA) or Map2k7 siRNA were cultured with 10 μM melatonin for 24 h, washed in PBS, and then grown in medium containing 0.2 mM H2O2 for 2 h. The expression of phosphorylated MAP2K7 (p-MAP2K7) and total MAP2K7 was determined by Western blotting. TUBA1A served as the control for loading. (E) GCs transfected with scrambled control siRNA (SC siRNA) or Map2k7 siRNA for 48 h were cultured with or without 0.2 mM H2O2 for 2 h. Cell lysates were collected for Western blot analysis of RAC1 activation (GTP-RAC1 levels) by GST-PAK1-PBD pulldown and of total RAC1 levels. (F) GCs transfected with scrambled control siRNA (SC siRNA) or Map2k7 siRNA for 24 h were cultured for another 24 h in the presence or absence of 10 μM melatonin before 2 h of H2O2 (0.2 mM) incubation. Cells were then processed for JNK determination. Data represent mean ± s.e.; n = 3. **Represents P < 0.01 vs control group. ##Represents P < 0.01 vs H2O2 group. N, not significant, P > 0.05.
