Description
In this manuscript, we described male-biased mutations in chrX genes in cancer. In this RNA-seq experiment we tested the transcriptional consequences of shRNA knockdown of one of those genes, CNKSR2 Overall design: Murine NIH 3T3 cells were infected with and selected for expression of lentiviruses expressing shRNAs targeting Cnksr2 (2 independent shRNA sequences) or a control shRNA (targeting RFP, a gene not present in these cells). Each was performed in biological triplicate independent cultures for n=9 total samples

Description
Mutation or deletion of Neurofibromin (NF1), an inhibitor of RAS signaling, frequently occurs in epithelial ovarian cancer (EOC), supporting therapies that target downstream RAS effectors, such as the RAF-MEK-ERK pathway. However, no comprehensive studies have been carried out testing the efficacy of MEK inhibition in NF1-deficient EOC. Here, we performed a detailed characterization of MEK inhibition in NF1-deficient EOC cell lines using kinome profiling and RNA sequencing. Our studies showed MEK inhibitors were ineffective at providing durable growth inhibition in NF1-deficient cells due to kinome reprogramming. MEKi-mediated destabilization of FOSL1 resulted in induced expression of RTKs and their downstream RAF and PI3K signaling overcoming MEKi therapy. MEKi synthetic enhancement screens identified BRD2 and BRD4 as integral mediators of the MEKi-induced RTK signatures. Inhibition of BET proteins using BET bromodomain inhibitors (BETi) blocked MEKi-induced RTK reprogramming, indicating BRD2 and BRD4 represent promising therapeutic targets in combination with MEKi to block resistance due to kinome reprogramming in NF1-deficient EOC. Overall design: Examination of the global effects on transcription in response to trametinib (GSK212) in A1847 cells.

Description
To investigate the systemic molecular changes occurring as a result of Dhr96 knockdown or over-expression, a comparison between knockdown or overexpression lines and their genetic controls were performed. 0-3 day old adult males or females were reared on 3 separate batches of diet (this was the standard diet we used for culturing Drosophila melanogaster and was made up of 10L water, 100g agar (USP #7060 Bio-serve), 350g Brewers dried yeast (Sunshine Health), 300g black treacle (Lyles), 150g sucrose (Tate & Lyle), 300g Difco dextrose (Becton Dickinson), 150g cornmeal (#1151, Bioserve), 100g wheatgerm (#1659, Bioserve), 200g soya bean flour (#S9633 Sigma Aldrich), 10g methyl-4-hydroxybenzoate (#H3647 Sigma Aldrich) in 10ml ethanol, 50ml proprionic acid (#P5561 Sigma Aldrich)). Each of these 3 batches was considered to represent independent biological replication. The RNA samples were hybridized to the Affymetrix Drosophila GeneChip 2.

Description
To test whether other genes were being silenced in the Cyp6g1 knockdown strain due to off-target RNAi effects, and whether other gene expression changes were contributing to the altered susceptibility to imidacloprid in these knockdown flies. A comparison between w;Act5C-GAL4/CyO; UAS:RNAi_Cyp6g1Hp2/TM3Sb and the genetic control w;Act-GAL4/CyO;+/TM3Sb was performed. Ten 2-3 day old adult males or females were transferred to sugar-agar plates and then collected at various time points (0, 2, 5, 8 hours). The RNA samples for up to three independent experiments per timepoint for each genotype were then pooled, in equal concentrations, before hybridisation to the Affymetrix Drosophila GeneChip 1.

Description
Foam cell formation from monocyte-derived macrophages is a hallmark of atheroscle-rotic lesions. Aspects of this process can be recapitulated in vitro by exposing MCSF-induced or platelet factor4 (CXCL4)-induced macrophages to oxidized (ox) or minimally modified (mm) low density lipoprotein (LDL). We measured gene expression in periph-eral blood mononuclear cells (PBMCs), monocytes and macrophages treated with CXCL1 (GRO-) or CCL2 (MCP-1) as well as foam cells induced by native LDL, mmLDL or oxLDL using 22 Affymetrix gene chips. Using an advanced Bayesian error-pooling approach and a heterogeneous error model (HEM) with a false discovery rate (FDR) <0.05, we found 5,303 of 22,215 probe sets to be significantly regulated in at least one of the conditions. Among a subset of 917 candidate genes that were preselected for their known biological functions in macrophage foamcell differentiation, we found that 290 genes met the above statistical criteria for significant differential expression patterns. While many expected genes were found to be upregulated by LDL and oxLDL, very few were induced by mmLDL. We also found induction of unexpected genes, most strikingly MHC-II and other dendritic cell markers such as CD11c. The gene expression patterns in response to oxLDL were similar in MCSF-induced and CXCL4-induced macrophages. Our findings suggest that LDL and oxLDL, but not mmLDL, induce a dendritic cell-like phenotype in macrophages, suggesting that these cells may be able to present antigens and support an immune response.
