Cross species transcriptomic signatures predict response to MK2 inhibition in mouse models of chronic inflammation

Project description:Translating observations from preclinical models to patients is one of the most pressing challenges in biomedical research. Part of the challenge derives from the necessity of studying preclinical therapeutic responses in genetically and environmentally homogenous mouse models, which exhibit less variability than genetically and environmentally heterogeneous humans. This problem is especially relevant for inflammatory bowel diseases (IBD), which are genetically complex and exhibit significant inter-patient heterogeneity in disease presentation and therapeutic response. Here, we show that mouse models of IBD exhibit variable responses to inhibition a MK2, a pro-inflammatory serine/threonine kinase, and that MK2 inhibition suppresses inflammation by targeting inflammatory monocytes and neutrophils. Using a computational approach (TransComp-R) that allows for cross-species comparison of transcriptomic features, we identified an IBD patient subgroup that is predicted to respond to MK2 inhibition and an independent preclinical model of chronic intestinal inflammation predicted to be non-responsive, which we validated experimentally. Thus, cross-species mouse-human translation approaches can help to identify patient subpopulations in which to deploy new therapies.

WT and Mk2/3 KO MEFs response to etoposide

Project description:Primary mouse embryonic fibroblasts (MEFs) from wt and MK2/3 KO mice were treated with 20µM etoposide. Primary MEFs from wt and MK2/3 KO mice were treated with 20µM etoposide and RNA extracted after 1h and 6h.

MK2 and MK3 regulate LPS-induced inflammatory response of macrophages [120min]

Project description:The p38MAPK downstream targets MK 2 and 3 are critical for the regulation of the macrophage response towards bacterial lipopolysaccharid (LPS). The extent these two kinases act cooperatively in regulating LPS-induced inflammatory cytokine expression and their distinct regulatory effects are still unclear. To address this point, whole transcriptome analyses had been performed using bone marrow derived macrophages (BMDM) generated from MK2-/- or MK2/3-/- animals and from wildtype littermates. The BMDM were treated with 100 ng/ml LPS for 120 minutes or with medium as control. Thereafter, total mRNA was isolated and subjected to array analysis using the SurePrint G3 Mouse 8x60K Microarray Kit from Agilent.
