Genome-wide identification of nitric-oxide regulated H3K9/14ac sites in Arabidopsis thaliana

ABSTRACT: We report on the identification of nitric-oxide regulated H3K9/14ac sites in Arabidopsis. For this purpose liquid grown Arabidopsis seedlings were treated with the natural NO-donor S-nitrosoglutathione (GSNO), GSNO in combination with the NO-scavenger cPTIO, GSH (control) or TSA (positive control). Material was crosslinked and harvested 3h and 16h after onset of the treatments. Then, quantitative analysis of the H3K9/14ac patterns across these treatment was performed using DiffBind. By comparison of the GSNO and GSNO/cPTIO treatment, NO-regulated H3K9/14ac sites were identified. These sites were then annotated to the nearest TSS. GO enrichment analysis revealed that NO affects H3K9/14ac at many stress-responsive and photosynthetic genes.

Project description:To further study the transcriptome of THP-1 human monocytes after exposure to S-Nitrosoglutathione (GSNO), we investigate whole genome microarray expression to identify genes regulated by exposure or not to GSNO. To further study the transcriptome of THP-1 human monocytes after exposure for 4 h to 50 ug / mL of S-Nitrosoglutathione-loaded polymeric Eudragit RL nanoparticles (GSNO-loaded ENP), we investigate whole genome microarray expression to identify genes regulated by exposure or not to 50 ug / mL of GSNO-loaded ENP. To further study the transcriptome of THP-1 human monocytes after exposure for 4 h to 200 ug / mL of empty polymeric Eudragit RL nanoparticles (empty ENP), we investigate whole genome microarray expression to identify genes regulated by exposure or not to 200 ug / mL of empty ENP. To further study the transcriptome of THP-1 human monocytes after exposure for 24 h to 50 ug / mL of S-Nitrosoglutathione-loaded polymeric Eudragit RL nanoparticles (GSNO-loaded ENP), we investigate whole genome microarray expression to identify genes regulated by exposure or not to 50 ug / mL of GSNO-loaded ENP.
