Ribosome profiling on heat shocked wild type and Mettl14 -/- mES cells

Project description:Abstract : "A hallmark of the cellular response to environmental stress is the formation of stress granules. Stress granules are RNA-protein assemblies that provide an adaptive response to stress; however, the basis for their formation and how they contribute to the stress response remains incompletely understood. Here we show that the mRNA modification N6-methyladenosine (m6A) is a mark that targets mRNAs to stress granules. We find that m6A mRNAs are highly enriched in stress granules, and this is mediated by m6A-induced liquid-liquid phase separation of the YTHDF family of m6A-binding proteins. These proteins bind poly-methylated m6A mRNAs, causing them to form liquid droplets that partition into stress granules. Moreover, disrupting either m6A or YTHDF proteins prevents stress granule formation." The goal of this experiment is to understand how recruitment of m6A mRNA to stress granules influences the translational response to heat shock. Result: we found that m6A-containing mRNA are preferentially repressed during stress, and that m6A is required for translational recovery after heat shock

Active ribosome profiling in SETD2 or METTL14 knockdown HepG2 cells

Project description:SETD2 is the specific methyltransferase of H3K36me3, while METTL14 is a critical subunit of the m6A methyltransferase complex. To evaluate the effect of SETD2 and METTL14 on translation, we conducted robosome profiling in SETD2 and METTL14 knockdown and control HepG2 cells. Our RNA ribosome profiling revealed that depletion of SETD2 and METTL14 resulted in a global reduction in RNA translation and the changes of translation efficiency were correlated between SETD2 and METTL14 knockdown cells.

Permanganate ChIP-seq analysis of Pol II in nonheat shocked and heat shocked Drosophila S2R+ cells and nonheat shocked BG3 cells

Project description:The genomic distribution of transcriptionally engaged Pol II in control and heat shocked cells was determined by combining formaldehyde crosslinking and permanganate oxidation of transcription bubbles Cells treated in succession with formaldehyde and then permanganate, were subjected to chromatin precipitation with Rpb3 antibody, and then the pattern of permanganate modifications were mapped genome-wide

Expression data from control and heat shocked mouse spermatocytes and hepatocytes

Project description:In somatic cells elevated temperature induces activation of the heat shock transcription factor 1 (HSF1) what leads to heat shock proteins synthesis and cytoprotection. However, in the male germ cells (spermatocytes) upon HSF1 activation, caspase-3 dependent apoptosis is induced and spermatogenic cells are actively eliminated. To elucidate a mechanism of such diverse HSF1 activity we carried out genome-wide transcriptional analysis in control and heat-shocked cells, either spermatogenic or somatic. As model somatic cells we used hepatocytes that respond to hyperthermia in a classical way by induction of heat shock genes transcription. As spermatogenic cells we used a fraction of cells enriched with spermatocytes, which are the most sensitive to damage in elevated temperatures. Using isolated spermatocytes we avoided the influence of the somatic testicular component on the our final results. Genes that are differently regulated during hyperthermia in both types of cells have been identified.

Identification of genes regulated by HSF1 in control and heat-shocked cells

Project description:To examine the regulation of HSF1-mediated gene expression in control and heat shock conditions, we performed DNA microarray analysis. mRNA levels in control and heat-shocked MEF cells, which were infected with adenovirus expressing scramble RNA or HSF1 short hairpin RNA, were analyzed by DNA microarray analysis using GeneChip Mouse Gene 1.0 ST Array (Affymetrix).

Genome-wide HSF1 binding sites in control and heat shocked spermatocytes and hepatocytes

Project description:In somatic cells elevated temperature induces activation of the heat shock transcription factor 1 (HSF1) what leads to heat shock proteins synthesis and cytoprotection. However, in the male germ cells (spermatocytes) upon HSF1 activation, caspase-3 dependent apoptosis is induced and spermatogenic cells are actively eliminated. To find out molecular targets of HSF1 in all promoter regions, and to elucidate a mechanism of such diverse HSF1 activity we carried out genome-wide HSF1 binding analysis in control and heat-shocked cells, either spermatogenic or somatic. As model somatic cells we used hepatocytes that respond to hyperthermia in a classical way by induction of heat shock genes transcription.
