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:TNF-alpha has a number of pro-atherogenic effects in macrovascular endothelial cells, including induction of leukocyte adhesion molecules and chemokines. We investigated the role of acyl-CoA synthetase 3 (ACSL3) in the response of cultured human macrovascular endothelial cells to TNF-alpha. TNF-alpha induced ACSL3 both in human umbilical vein endothelial cells (HUVECs) and in human coronary artery endothelial cells (HCAECs). RNA sequencing demonstrated that knockdown of ACSL3 had no marked effects on the TNF-alpha transcriptome in HCAECs. Instead, ACSL3 was required for TNF-alpha-induced lipid droplet formation from fatty acids.

Project description:We quantified differential gene (mRNA) expression in human coronary artery cells treated with native HDL, reconstituted HDL, lipid-free apolipoprotein A-I, small unilamellar vesicles, or PBS control. These data were used to determine which genes are regulated by native HDL compared to components of HDL and categorize data based on shared sets of genes and distinct sets of genes regulated by each component. Each group had a n=5 and gene expression changes for each condition were compared to control PBS-treated HCAECs

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.

Project description:Background: Melatonin is considered to be a polyfunctional master regulator in animals and higher plants. Exogenous melatonin inhibits plant infection by multiple diseases; however, the role of melatonin in cucumber green mottle mosaic virus (CGMMV) infection remains unknown. Results: In this study, we demonstrated that exogenous melatonin treatment can effectively control CGMMV infection. The greatest control effect was achieved by 3 days of root irrigation at a melatonin concentration of 50 µM. Exogenous melatonin showed preventive and therapeutic effects against CGMMV infection at early stage in tobacco and cucumber. We utilized RNA sequencing technology to compare the expression profiles of mock-inoculated, CGMMV-infected, and melatonin+CGMMV-infected tobacco leaves. Defense-related gene CRISP1 was specifically upregulated in response to melatonin, but not to salicylic acid (SA). Silencing CRISP1 enhanced the preventive effects of melatonin on CGMMV infection, but had no effect on CGMMV infection. We also found exogenous melatonin has preventive effects against another Tobamovirus, pepper mild mottle virus (PMMoV) infection. Conclusions: Together, these results indicate that exogenous melatonin controls two Tobamovirus infection and inhibition of CRISP1 enhanced melatonin control effects against CGMMV infection, which may lead to the development of a novel melatonin treatment for Tobamovirus control.

Project description:The proper response to shear stress involves multiple cell components of the vascular wall including endothelial cells (ECs), smooth muscle cells (SMCs), and the intercellular communications between them. Mounting evidence indicates that retinoid acid receptor-related orphan receptor-α (RORα) mediates many biological activities of melatonin including transactivation of transcriptional factors, and anti-inflammation. In this study we investigated the effect of melatonin on endothelial cells-derived exosomal miRNA expression. We used microarrays to detail the global program of gene expression underlying melatonin treatment and identified distinct classes of dys-regulated genes during this process.
