Natural melatonin fluctuation and its minimally invasive simulation in the zebra finch [PDF]
PeerJ, 2016 Melatonin is a key hormone in the regulation of circadian rhythms of vertebrates, including songbirds. Understanding diurnal melatonin fluctuations and being able to reverse or simulate natural melatonin levels are critical to investigating the influence

Melatonin, Melatonin Receptors and Melanophores: A Moving Story [PDF]
Pigment Cell Research, 2004 Melatonin (5‐methoxy N‐acetyltryptamine) is a hormone synthesized and released from the pineal gland at night, which acts on specific high affinity G‐protein coupled receptors to regulate various aspects of physiology and behaviour, including circadian and seasonal responses, and some retinal, cardiovascular and immunological functions.

Advanced Science, EarlyView.Orally administered recombinant human type III collagen protects the gastric mucosa from ethanol‐induced injury by coordinating redox homeostasis, epithelial barrier repair, and arachidonic acid–prostaglandin metabolism. Gastric digestion releases the pentapeptide GPAEF, which interacts with the Pla2g4a promoter G‐quadruplex in a structure‐dependent ...

Advanced Science, EarlyView.Melatonin engages MT1/MT2 receptors to suppress STAT1‐driven USP18 upregulation, thereby redirecting PKM2 ubiquitination from K33‐linked autophagic degradation toward K27‐linked nuclear translocation. This prevents PKM2‐mediated proinflammatory gene expression in the heart, alleviating doxorubicin‐induced cardiotoxicity without compromising antitumor ...

Engineered Chiral Probiotics Ameliorate MASH via Gut–Liver Axis
Advanced Science, EarlyView.A chiral gold nanozyme was coated onto the gut commensal bacterium Faecalibacterium duncaniae (F. duncaniae) to create an engineered probiotic. In mouse models of MASH, this orally administered living therapeutic protected the bacterium against oxidative stress, enhanced its gut colonization, reversed steatosis, inflammation, and fibrosis, and improved
