In depth review of how deficiency of butyrate and melatonin compromise gut and overall mitochondrial function and lead to lower levels of other key molecules in cellular metabolism like sirtuins, PGC-1α and NAD+.
People with psoriasis tend to have lower levels of melatonin than average at 2 a.m and higher than average at 6am, 8 am & noon.
Melatonin supplementation benefits male hypertensive and female obese rats due to suppression of metabolic disorders and lethal arrhythmia risk. Arrhythmia is a problem with the rate or rhythm of your heartbeat. Protection against arrhythmia may attributed, at least in part, to up-regulation of myocardial Cx43, which is a protein that is essential for the formation of heart structures.
Single-center, open-label, randomized clinical trial done on Covid patients in Iraq to study melatonin supplementation for Covid treatment. All 158 patients got standard care, 82 of those patients ate 10mg melatonin each night. Thrombosis and sepsis developed significantly less in melatonin group. 13 patients in control group died vs 1 person in the melatonin group.
The role of TRPV4 channel present in human ciliary body epithelial cells in AANAT production was studied. AANAT, Aralkylamine N-acetyltransferase seems to be the key enzyme involved in producing melatonin from serotonin. In rodents, transcriptional activation of aanat gene is the classical mechanism to induce melatonin biosynthesis. TRPV4 is present in the human ciliary body and ciliary body epithelial cells. Activating TRPV4 channel increases the expression of AANAT, which elevates the concentration of NAS and melatonin
In various studies where patients are treated for gastric ulcers, those on melatonin did better.
Melatonin plays a key role in intracellular membrane integrity, especially when a cell is in under stress. Melatonin plays role in maintaining a high ATP:ADP ratio, which suppresses glycolysis. Supplemental melatonin shown to accumulate in all cells, accumulates 10x in membrane compared to mitochondria. Plays unique role in fat/water interfaces, as it can combine with both. Biomolecular condensates play a big role in brain disorders and are shaped by complex relationships between membraneless organelles, membranes/lipid rafts, ATP, RNA, and most of all, stress. Melatonin’s intimate association with each of these decisive influencers may position it as an important mediator of sorting out of these condensates in health and disease via ATP-dependent mechanisms.
Red blood cells exposed to oxidative stress will consume melatonin and use it for protect against deterioration.
Studies show that melatonin ameliorates hyperinsulinemia, insulin resistance, and insulin sensitivity.
Supplementing mice with melatonin increases butyrate production in their gut via bacteria, conversely antibiotics severely impair this butyrate production. When mice are poisoned with titanium nanoparticles to induce bone deterioration, butyrate has a protective effect against bone loss. This protective effect is specifically dependent on the GPR109A receptor that seems to be activated by the butyrate enriched gut microbiota.
This paper investigates the production melatonin in the gut, notably it being unrelated to the day/light cycle and how eating patterns affect its production, and what the produced melatonin may be used for.
