Project description:Blastocyst vitrification has significantly changed the embryo transfer method.Vitrification of human blastocysts may result in higher implantation success rates and heavier birth weightsin subsequent frozen embryo transfer cycles. This study investigated the effects of vitrification onthe transcriptome profiles and implantationof mouse blastocysts. First, a fold-change cutoff of±2 was used to distinguish differentially expressed genes. Transcriptomic analysis indicatedthat differentially expressed genes of vitrified–warmed blastocysts were mainly related to cell development, proliferation, projection,motility,and calcium-binding protein and MAPK-related signaling pathways.Second, we performed reverse transcriptase-quantitative polymerase chain reaction to verify the gene expression in the next-generation sequencing results, including increased genes such as GPR132, CDK6, FOS, and NFAT2and decreased genes such as DKK3 and MAPK10. Finally, blastocysts may communicate with the maternal uterine via microRNA to regulate gene expression in the embryo and endometrium. Prediction of microRNA candidateswas performed using the results of next-generation sequencing transcriptomicanalysis and validatedthroughmicroRNA assay. A total of 12 validated blastocyte microRNAs may affect uterine epithelial cell adhesion, trophectoderm development, invasive capacity, or immune responses to increase pregnancy success rates. In conclusion, vitrification alters the transcriptome of mouse blastocysts, resulting in small changes in gene expression and an increased implantation success rate.

Project description:Melatonin (N-acetyl-5-methoxytryptamine) is a ubiquitous indolamine that plays important roles in biological processes in different organisms. Recently, it has been found to have a important role in the antioxidant response in yeast. In this study the transcriptomic response to mild oxidative stress driven by Saccharomyces cerevisiae strain QA23 supplemented to different concentrations of melatonin (5 and 25 µM) is assessed.

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:Blastocyst vitrification has improved embryo transfer methods, leading to higher implantation success rates and better pregnancy outcomes in subsequent frozen embryo transfer cycles. In this study, we used mouse blastocysts as a model to simulate the transcriptional changes caused by vitrifying human blastocysts and to further investigate their effects. Utilizing a human vitrification protocol, we implanted both vitrified and fresh embryos into mice and observed a higher implantation success rate for the vitrified embryos. Transcriptomic analysis revealed that vitrified-warmed blastocysts exhibited differential gene expression primarily associated with thermogenesis, chemical carcinogenesis-reactive oxygen species, oxidative phosphorylation, immune response, and MAPK-related signaling pathways. To validate the next-generation sequencing results, we performed reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR), which confirmed increased expression of genes such as Cdk6 and Nfat2, and decreased expression of genes such as Dkk3 and Mapk10. Among these pathways, immune responses and MAPK-related signaling pathways indicate that embryos need to communicate with the external environment, likely through microRNAs. We used gene-microRNA interaction predictions to anticipate potential embryonic microRNA expressions and conducted an analysis of embryonic microRNA expression. Twelve microRNAs exhibited expression patterns consistent with the predicted results, potentially affecting uterine epithelial cell adhesion, trophectoderm development, invasive capacity, or immune responses. Our findings suggest that vitrification induces transcriptomic changes in mouse blastocysts, and even small changes in gene expression can increase implantation success.

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:Changes in gene expression induced by the Cryotop vitrification procedure in bovine blastocysts using Agilent EmbryoGENE microarray slides. Bovine in vitro-produced embryos at the blastocyst stage (144 to 156 hours post insemination) were vitrified using the Cryotop system and compared with non-vitrified (control) embryos. After vitrification, the embryos were warmed and cultured for an additional 4 hours. Embryos that re-expanded or developed to the expanded blastocyst stage were used for microarray analysis. Four pools of vitrified embryos were hybridized against four pools of control embryos in a dye-swap design.
