Project description:This study was designed to investigate the effect of a novel model of early life stress (MMS) on DNA methylation within the hypothalamus
Project description:Bipolar disorder (BD) is a severe mental disorder characterized by repeated mood swings. Although genetic factors with small effect sizes are collectively associated with the pathophysiology of BD, the underlying molecular mechanisms, especially how environmental factors affect the brain genome, remain largely unknown. We revealed neuronal cell-type-specific, pathophysiology-related DNA methylation changes in the prefrontal cortex (PFC) of BD patients, highlighting the importance of the neural epigenome for understanding BD.
Project description:Polyploidy has been implicated in genome instability and tumorigenesis. We use Schizosaccharomyces pombe diploids as a model for studying the consequences of whole genome duplications on genome integrity. In this study, our aim is to investigate the transcriptional profile between haploid and diploid S. pombe in unperturbed and MMS treated conditions (0.0075% MMS, 4 hours @ 32 degrees Celsius in YES media).
Project description:The cellular response to treatment with DNA-damaging substances at low concentrations which are genotoxic but do not have a strong cytotoxic effect are of special interest. In addition, environmental variations that influence growth conditions, e.g. different media, and individual fitness, e.g. different strains, are likely to influence and modulate the adverse effects of individual DNA damaging substances. At sub-cytotoxic levels, DNA damaging substances play an important role in the accumulation of genomic mutations. In longer living organisms, like humans and other mammals, exposure to DNA damaging substances over extended period of time is a critical factor that contributes to the development of various diseases and in particular of tumors. The aim of our work was to study how strain background and growth conditions influence respond to DNA damage caused by low doses of MMS and which part of these changes is responsible for their sensitivity to toxic conditions. We analyzed sensitivity of two yeast strains FF18984 and BY4742 to MMS in media with limited and full nutrient availability. Keywords: Yeast, S.cerevisiae, MMS, stress response, DNA damage
Project description:We are investigating the transcriptional response of Anc1 deficient yeast under basal and MMS exposed conditions We used microarrays to detail the global programme of gene expression underlying the MMS response in WT and Anc1 deficient yeast Keywords: dose
Project description:We are investigating the transcriptional response of Anc1 deficient yeast under basal and MMS exposed conditions; We used microarrays to detail the global programme of gene expression underlying the MMS response in WT and Anc1 deficient yeast Experiment Overall Design: Yeast strains either WT or Anc1 deficient were exposed or unexposed to MMS
Project description:This is transcription analysis of genes regulated by the INO80 chromatin remodeling complex in S-phase of the cell cycle after MMS treatment. Wildtype and ino80 mutant cells were first synchronized at G1 using alpha-factor, the cells were released in to S-phase in the presence of 0.02% MMS. After 45 minutes, total RNA was isolated and analyzed to identify genes that are regulated by INO80 under such conditions.
