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:Breast cancer (BC) is the most prevalent and lethal tumor among women worldwide.
Although the antitumor effects of melatonin are well documented, its precise molecular
mechanisms in specific breast cancer subtypes remain unclear. This dataset provides
proteomic data from total protein extracts of two breast cancer cell lines [MCF-7
(ER+and PR+) and MDA-MB-468 (triple negative) treated with melatonin. The aim of
the study was to identify melatonin-induced changes in global protein expression and to
assess its potential as a therapeutic modulator in hormone-responsive and triple-negative
breast cancer.

Project description:This microarray data was assessed in CNOT knockdown or non-treated non small lung cancer cells (A549 and H1299). This microarray data was assessed in melatonin treated compared to non-treated glioblastoma stem like cells (XO1 and XO2).

Project description:Melatonin plays a potential role in multiple plant developmental processes and stress response. However, there are no reports regarding exogenous melatonin promoting rice seed germination under salinity and nor about the underlying molecular mechanisms at genome-wide. Here, we revealed that exogenous application of melatonin conferred roles in promoting rice seed germination under salinity. The putative molecular mechanisms of exogenous melatonin in promoting rice seed germination under high salinity were further investigated through metabolomic and transcriptomic analyses. The results state clearly that the phytohormone contents were reprogrammed, the activities of SOD, CAT, POD were enhanced, and the total antioxidant capacity was activated under salinity by exogenous melatonin. Additionally, melatonin-pre-treated seeds exhibited higher concentrations of glycosides than non-treated seeds under salinity. Furthermore, exogenous melatonin alleviated the accumulation of fatty acids induced by salinity. Genome-wide transcriptomic profiling identified 7160 transcripts that were differentially expressed in NaCl, MT100 and control. Pathway and GO term enrichment analysis revealed that genes involved in the response to oxidative stress, hormone metabolism, heme building, mitochondrion, tricarboxylic acid transformation were altered after melatonin pre-treatment under salinity. This study provides the first evidence of the protective roles of exogenous melatonin in increasing rice seed germination under salt stress, mainly via activation of antioxidants and modulation of metabolic homeostasis.

Project description:To explore the role of melatonin in hepatocellular carcinoma,we performed high-throughput mRNA sequencing (mRNA-seq) with HepG2 cells treated with 1 mM melatonin for 24 h and 48 h separately. We then performed gene expression profiling analysis using data obtained from RNA-seq of HepG2 cells at two time points.

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:Mice are 4 weeks old on a C57Bl/6N background strain, hearts were collected at ZT15, following 1 week daily administration of melatonin at 4mg/L (human equivalent of 5mg dose) in the drinking water from ZT12-15. The microarray approach allows the investigation of gene expression changes of all genes in WT control vs. WT melatonin-treated hearts.

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.
