Project description:These paired RIP experiments were designed to determine specific ncRNAs that associated with either Lsd1 (Lysine specific demethylase 1) complex or Bre1.
Project description:SILAC labelled peptides from control and UV or 2-deoxy glucose treated A549 cells. Control is light labelled and treatment groups are heavy labelled. Fractions are as per below:
UV1: APM-0331-2 to APM-0331-6

2DG1: APM-0331-7 to APM-0331-11
2DG2: APM-0331-17 to APM-0331-21
Project description:In order to assess the prevalence of cotranslational assembly of protein complexes we performed RIp-chip experiments with many proteins that do not conatin RNA-binding motifs

Project description:Viral infection is commonly associated with virus-driven hijacking of host proteins. We describe a novel mechanism by which influenza virus impacts host cells through the interaction of influenza NS1 protein with the infected cell epigenome. We show that the NS1 protein of influenza A H3N2 targets the transcription elongation PAF1 complex (hPAF1C). We demonstrate that binding of NS1 to hPAF1C results in suppression of hPAF1C-mediated transcriptional elongation. More importantly,in the following data sets, we show that hPAF1 plays a crucial role in the antiviral response. Loss of hPAF1C reduces antiviral gene expression and reduces inducible transcription of target genes after stimulation with viral RNA analogue poly(I:C), vesicular stomatitis virus (VSV), exogenous recombinant IFN(beta) and influenza virus (H1N1). This study underscores the importance of hPAF1C in controlling inducible antiviral gene expression. Untreated (no siRNA), control siRNA-treated and hPAF1 siRNA-treated A549 cells were stimulated with A/Puerto Rico/8/1934 influenza virus (H1N1) or vesicular stomatitis virus (VSV). Total RNA was isolated with the Qiagen RNeasy mini kit. 200ng of total RNA per sample was used to prepare biotin-labeled RNA using MessageAmp™ Premier RNA Amplification Kit (Applied Biosystems) and hybridized to HumanHT-12 v4 Expression BeadChips (Illumina). Data analysis was performed using the GeneSpring GX11.0 software (Agilent Technologies). 3 biological replicates per condition
