Nucleosome occupancy in yeast BY4741and a strain lacking MSN2 and MSN4 responding to 20 min treatment with 0.4mM H2O2

ABSTRACT: Numerous factors have been implicated in regulating gene expression changes, including changes to nucleosome occupancy. Here we followed dynamic changes to nucleosome occupancy, gene expression and DNA binding of the transcription factor Msn2p genome-wide in yeast cells responding to hydrogen peroxide and reveal new relationships between regulators of stress-dependent gene expression in yeast.

Nucleosome occupancy in yeast BY4741and a strain lacking MSN2 and MSN4 responding to 20 min treatment with 0.4mM H2O2

Project description:Numerous factors have been implicated in regulating gene expression changes, including changes to nucleosome occupancy. Here we followed dynamic changes to nucleosome occupancy, gene expression and DNA binding of the transcription factor Msn2p genome-wide in yeast cells responding to hydrogen peroxide and reveal new relationships between regulators of stress-dependent gene expression in yeast. Nucleosome occupancy was measured in the S288c derivative BY4741 and a strain lacking MSN2 and MSN4. Nucleosomes were isolated from unstressed yeast and yeast treated for 20 min with 0.4mM H2O2. Nucleosomal samples were compared in a 2-color, competitive hybridization to sheared genomic DNA.

Project description:Numerous factors have been implicated in regulating gene expression changes, including changes to nucleosome occupancy. Here we followed dynamic changes to nucleosome occupancy, gene expression and DNA binding of the transcription factor Msn2p genome-wide in yeast cells responding to hydrogen peroxide. and reveal new relationships between regulators of stress-dependent gene expression in yeast. Msn2p occupancy was measured in response to 0.4mM H2O2 in the S288c derivative BY4741 with an integrated myc-tagged Msn2p. A single replicate of the time course was performed with time points at 0, 4, 12, 20, 40 and 60 minutes after treatment.

Gene expression was measured in response to 0.4mM H2O2 in the S288c derivative BY4741 in wild-type cells and cells lacking MSN2 and MSN4. A single replicate of a time course spanning from 4 to 60 minutes after treatment in each cell type. An additional 3 repliactes were collected from cells 30 minutes after treatment.

Nucleosome occupancy dynamics in yeast BY4741 responding to 0.4mM H2O2 over time (0-60 min)

Project description:Numerous factors have been implicated in regulating gene expression changes, including changes to nucleosome occupancy. Here we followed dynamic changes to nucleosome occupancy, gene expression and DNA binding of the transcription factor Msn2p genome-wide in yeast cells responding to hydrogen peroxide to reveal new relationships between regulators of stress-dependent gene expression. Nucleosome occupancy was measured by MNase-Seq in response to .4mM H2O2 in the S288c yeast derivative BY4741. A single replicate was performed for the time-course experiment with time points at 0, 4, 12, 20, 40 and 60 minutes after treatment.
