Melatonin Function and Crosstalk with Other Phytohormones under Normal and Stressful Conditions

Genes, 2022
Melatonin was discovered in plants in the late nineties, but its role, signaling, and crosstalk with other phytohormones remain unknown. Research on melatonin in plants has risen dramatically in recent years and the role of this putative plant hormone ...

Discovery of H2 Receptor Antagonists as Colistin Enhancers by Targeting Acid Stress Response

Advanced Science, EarlyView.
This study identifies YqgB as a key target for restoring colistin susceptibility in mcr‐positive pathogens under acidic conditions by remodeling phospholipid composition and reducing LPS modification. Deep learning‐based screening reveals H2 receptor antagonists as novel colistin adjuvants. Further investigations indicate that ranitidine and famotidine

Melatonin Signaling Controls the Daily Rhythm in Blood Glucose Levels Independent of Peripheral Clocks. [PDF]

PLoS ONE, 2016
Melatonin is rhythmically secreted by both the pineal gland and retina in a circadian fashion, with its peak synthesis occurring during the night. Once synthesized, melatonin exerts its effects by binding to two specific G-protein coupled receptors ...

Seasonal Variation of Melatonin Concentration and mRNA Expression of Melatonin-Related Genes in Developing Ovarian Follicles of Mares Kept under Natural Photoperiods in the Southern Hemisphere

Animals, 2023
This study investigated the seasonal variations in mRNA expression of FSH (Fshr), LH (Lhr) receptors, melatonin (Mt1 and Mt2) receptors, melatonin-synthetizing enzymes (Asmt and Aanat) and melatonin concentration in developing follicles from mares raised

Rapid Remodeling of the Human Gut Microbiome in Response to Short‐Term Animal Product Restriction and Associations with Host Molecular Phenotypes

Advanced Science, EarlyView.
A real‐world model of structured animal product restriction practiced for religious reasons reveals the dynamic adaptability of the human gut microbiome to dietary change and uncovers reductions in diversity and rare taxa loss. Integrated microbiome, metabolomic, and proteomic analyses uncover coordinated taxonomic and molecular shifts and identify ...

Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System

Advanced Science, EarlyView.
Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...

Melatonin Modulates the GABAergic Response in Cultured Rat Hippocampal Neurons

Journal of Pharmacological Sciences, 2012
In the present study, we investigated the effect of melatonin on the GABA-induced current (IGABA) and GABAergic miniature inhibitory postsynaptic currents (mIPSCs) in cultured rat hippocampal neurons using the whole-cell patch-clamp technique.
