Project description:Melatonin is a well-known agent that plays multiple roles in animals. Its possible function in plants is less clear. In the present study, we tested the effect of melatonin (N-acetyl-5-methoxytryptamine) on soybean growth and development. Both spraying of leaves and seed-coating with melatonin significantly promoted soybean growth as judged from leaf size and plant height. This enhancement was also observed in soybean production and their fatty acid content. Melatonin increased pod number, seed number and seed weight. However, the 100-seed weight was not influenced by melatonin application. Melatonin also improved soybean tolerance to salt and drought stresses. Transcriptome analysis revealed that melatonin up-regulated the expression of many genes and alleviated the inhibitory effects of salt stress on gene expressions. Further detailed analysis of the affected pathways documents that melatonin likely achieved its promotional roles in soybean through enhancement of genes involved in cell division, photosynthesis, carbohydrate metabolism, fatty acid biosynthesis and ascorbate metabolism. Our results demonstrate that melatonin has significant potential for improving of soybean growth and seed production. Further study should uncover more about the molecular mechanisms of melatoninM-bM-^@M-^Ys function in soybeans and other crops. Four different treatments were chosen, water, salt, 100M-BM-5M melatonin and salt plus 100M-BM-5M melatonin. The comparison of salt/melatonin-treated sample versus water-treated sample reveals salt or melatonin induced transcriptome changes. The comparison of melatonin plus salt treated sample versus salt-treated sample reveals melatonin induced changes when salt exists.

Project description:Melatonin has been reported to play crucial roles in regulating meat quality, improving reproductive properties and maintaining intestinal health in animal production, but whether it regulates skeletal muscle development in weaned piglet is rarely studied. This study was conducted to investigate the effects of melatonin on growth performance, skeletal muscle development and lipid metabolism in animals by intragastric administration of melatonin solution. Twelve 28-day-old DLY (Duroc × Landrace × Yorkshire) weaned piglets with similar body weight were randomly divided into two groups: control group and melatonin group. The results showed that melatonin supplementation for 23 days had no effect on growth performance, but significantly reduced serum glucose content (P<0.05). Remarkably, melatonin increased longissimus dorsi muscle (LDM) weight, eye muscle area and decreased the liver weight in weaned piglets (P<0.05). In addition, the cross-sectional area of muscle fibers was increased (P<0.05), while triglyceride (TG) levels were decreased in LDM and psoas major muscle (PMM) by melatonin treatment (P<0.05). Transcriptome sequencing showed melatonin induced the expression of genes related to skeletal muscle hypertrophy and fatty acid oxidation. Enrichment analysis indicated that melatonin regulated cholesterol metabolism, protein digestion and absorption and mitophagy signaling pathways in muscle. Gene set enrichment analysis (GSEA) also confirmed the effects of melatonin on skeletal muscle development and mitochondrial structure and function. Moreover, quantitative real-time polymerase chain reaction (qPCR) analysis revealed that melatonin supplementation elevated the gene expression of cell differentiation and muscle fiber development, including paired box 7 (PAX7), myogenin (MYOG), myosin heavy chain (MYHC) ⅡA and MYHC ⅡB (P<0.05), which was accompanied by increased insulin like growth factor 1 (IGF1) and insulin like growth factor binding protein 5 (IGFBP5) expression in LDM (P<0.05). Additionally, melatonin regulated lipid metabolism and activated mitochondrial function in muscle by increasing the mRNA abundance of cytochrome c oxidase subunit 6A (COX6A), COX5B and carnitine palmitoyltransferase 2 (CPT2) and decreasing the mRNA expression of peroxisome proliferator activated receptor gamma (PPARG), Acetyl-CoA carboxylase (ACC) and fatty acid binding protein 4 (FABP4) (P<0.05). Together, our results suggest that melatonin could promote skeletal muscle growth and muscle fiber hypertrophy, improve mitochondrial function and decrease fat deposition in muscle.

Project description:Melatonin, a natural phytohormone present in most plants, plays multiple roles in plant growth and stress responses. Although melatonin biosynthesis-related genes have been suggested to possess diverse biological functions, their roles and functional mechanisms in regulating rice grain yield remain largely unexplored. Here, we revealed that a rice caffeic acid O-methyltransferase (OsCOMT) gene is involved in melatonin biosynthesis through in vitro and in vivo evidences. Transgenic assays show OsCOMT significantly delays leaf senescence at the grain filling stage, and then improves photosynthesis efficiency. Further experimental and transcriptomic data suggest that OsCOMT inhibits the degradation of chlorophyll and chloroplast, which in turn delay leaf senescence. Histological analysis also reveals the role of OsCOMT in the development of vascular bundle system in rice. The levels of melatonin and cytokinin were significantly increased in the culm of OsCOMT-overexpression plant relative to those of the wild-type (WT). In the OsCOMT-overexpression line, the cytokinin-biosynthesizing genes were up-regulated and the cytokinin-degrading genes were down-regulated, thereby increasing the cytokinin levels compared with the WT. Thus, OsCOMT-mediated vascular patterning may result from the crosstalk between melatonin and cytokinin. More importantly, OsCOMT significantly increased grain number and yield production of rice in various background, including Nipponbare (NIP) and Suken118 (SK118). Our findings show novel insights into melatonin-mediated leaf senescence and vascular patterning, and provide a new strategy to enhance rice yield production.

Project description:Physiologically based pharmacokinetic (PBPK) models were developed using MATLAB Simulink(®) to predict diurnal variations of endogenous melatonin with light as well as pharmacokinetics of exogenous melatonin via different routes of administration. The model was structured using whole body, including pineal and saliva compartments, and parameterized based on the literature values for endogenous melatonin. It was then optimized by including various intensities of light and various dosage and formulation of melatonin. The model predictions generally have a good fit with available experimental data as evaluated by mean squared errors and ratios between model-predicted and observed values considering large variations in melatonin secretion and pharmacokinetics as reported in the literature. It also demonstrates the capability and usefulness in simulating plasma and salivary concentrations of melatonin under different light conditions and the interaction of endogenous melatonin with the pharmacokinetics of exogenous melatonin. Given the mechanistic approach and programming flexibility of MATLAB Simulink(®), the PBPK model could provide predictions of endogenous melatonin rhythms and pharmacokinetic changes in response to environmental (light) and experimental (dosage and route of administration) conditions. Furthermore, the model may be used to optimize the combined treatment using light exposure and exogenous melatonin for maximal phase advances or delays

Project description:Objective: Melatonin and auxin are both tryptophan-derived indole molecules. Much attention has been given to proposed auxin-like activities of melatonin (regulating growth concentration-dependently). However, it still largely remains unclear whether melatonin and auxin regulate signalling pathways in a similar fashion. The purpose of this study is to directly compare the transcriptome response of Arabidopsis with melatonin or auxin. Method: mRNA profiles of 12-day old rosettes treated for a further of 3 days with +/- melatonin (5µM, 1005µM) or NAA(4.5µM) were generated by RNA-sequencing in triplicates (three independent biological experiments), using Illumina NextSeq 550 technology. Results: Comparative global transcriptome analysis conducted on Arabidopsis rosette treated with melatonin or NAA under exact same set of experimental conditions revealed differential number of genes and type of pathways. While auxin (4.5µM) regulated a large number of genes and elicited a diverse response, melatonin (100µM) showed a modest effect on transcriptome with only few genes significantly regulated whereas none regulated at approximately equimolar concentration with NAA (5µM) as compared to untreated solvent control (0.1% EtOH). Interestingly, the most prominent category of genes regulated by melatonin trended towards biotic stress defense pathways. Conclusions: These findings indicate that melatonin and auxin act quite differently toward signaling pathways in Arabidopsis. Melatonin has its own set of mechanisms to exert its functions, with strong inclination toward biotic defense pathways.

Project description:Melatonin is a known modulator of follicle development, it acts through several molecular cascades via binding to its two high-affinity, G-protein coupled receptors MT1 and MT2. Even though it is believed that melatonin can modulate granulosa cell (GC) functions, there is still limited knowledge of how it can act in human GC through MT1 and MT2 and which one is the major receptor implicated in the effects of melatonin on the metabolic processes in the dominant follicle. To better characterize the roles of the MT1 and MT2 receptors on the effects of melatonin on follicular atresia and the regulation of proliferation and differentiation of granulosa cells during the antral stage, human granulosa-like tumor cells (KGN) were treated with specific melatonin receptor agonists and antagonists, and gene expression was analyzed with RNA-seq technology. Following appropriate normalization and the application of a fold change cut-off of 1.5 (FC 1.5, p ≤ 0.05) for each treatment, lists of the principal differentially expressed genes (DEGs) are generated. Analysis of major upstream regulators suggested that the MT1 receptor may be involved in the melatonin antiproliferative effect by reprogramming the metabolism of human GC by activating the PKB signaling pathway. Our data suggest that melatonin may act complementary through both MT1 and MT2 receptors to modulate human GC steroidogenesis, proliferation, and differentiation. However, MT2 receptors may be the ones implicated in transducing the effects of melatonin on the prevention of GC luteinization and follicle atresia at the antral follicular stage through stimulating the PKA pathway.
