Project description:The project is aimed at characterizing the secretome of a human opportunistic fungal pathogen Candida glabrata. Additionally, the effect of loss of a family of eleven aspartyl proteases (Cg Yapsins) on the Candida glabrata secretome is studied.
Project description:We report that full length TET1 (TET1-FL) overexpression fails to induce global DNA demethylation in HEK293T cells. The preferential binding of TET1-FL to hypomethylated CpG islands (CGIs) through its CXXC domain leads to its inhibited 5-hydroxymethylcytosine (5hmC) production as methylation level increases. TET1-FL-induced 5hmC accumulates at CGI edges, while TET1 knockdown induces methylation spreading from methylated edges into hypomethylated CGIs. However, TET1 can regulate gene transcription independent of its dioxygenase catalytic function. Thus, our results identify TET1 as a maintenance DNA demethylase that does not purposely decrease methylation levels, but specifically maintains the DNA hypomethylation state of CGIs in adult cells.

Project description:Plants are subjected to perpetual fluctuations of light intensity and spectral composition in their natural growth environment, particularly due to movement of clouds and upper canopy leaves. Sudden exposure to intense light is accompanied by absorption of excess light energy, which results in an overload of photosynthetic electron transport chain and generation of reactive oxygen species in and around thylakoid membranes. To cope with this photooxidative stress and to prevent chronic photoinhibition under dynamically changing light intensities, plants have evolved various short- and long-term photoprotective mechanisms. We used quantitative mass spectrometry to investigate long-term acclimation of Arabidopsis thaliana leaf proteome to fluctuating light (FL) which induces photooxidative stress. After three days of FL exposure the proteomes of young and mature leaves were analyzed separately in the morning and at the end of day to examine possible interaction between FL acclimation and leaf development or time of day.
Project description:The main goal of this project is to identify proteins in Candida glabrata that interact with histones H3 (CgHht) and H4 (CgHhf) under normal and MMS-treatment conditions.
Project description:Goal of the experiment: Analysis of gene expression changes in the cortex, striatum, hippocampus, hypothalamus, Drd2-MSNs and Drd1-MSNs of mice with a postnatal, neuron-specific ablation of GLP or G9a as compared to control mice. For microarray analysis, hippocampus, hypothalamus, cortex and striatum of Camk2a-Cre; GLPfl/fl, Camk2a-Cre; G9afl/fl and age (10-14 week old) and sex matched littermate controls were used for total RNA purification. Four biological replicates were performed for each experiment. Polyribosome associated mRNAs from five, age (10-14 week old) and sex matched Drd1-Cre; Drd1-bacTRAP; G9afl/fl, or Drd2-Cre; Drd2-bacTRAP; G9afl/fl and Drd1-bacTRAP; G9afl/fl or Drd2-bacTRAP; G9afl/fl control mice were used. Three biological replicates were performed for each experiment.
Project description:The major goal of this project is to identify proteins that interact with CgYps1 aspartyl protease in logarithmic-phase Candida glabrata cells.
Project description:BACE1 role in reactive astrocytes are unknown. We used single cell RNA sequencing (scRNA-seq) to analyze reactive astrocytes in mice with and without germline Bace1. We also examine reactive astrocytes in the case of adult Bace1 conditional knockout on a 5xFAD Alzheimer's disease mouse model.
