Project description:Many symptoms associated with allergic asthma result from the sequelae of type 2 inflammation. Interleukin (IL)-25 promotes type 2 inflammatory responses, and T2M cells represent an IL-4 and IL-13 producing granulocytic IL-25 responsive population. We used microarrays to characterize the gene expression profile of T2M cells, and compared T2M cells to other inflammatory subsets (eosinophils, neutrophils, and macrophages) in the lungs of mice with IL-25-induced pulmonary inflammation.

Inflammatory subsets were isolated from the lungs of IL-25 treated 4get mice for RNA extraction and hybridization on Affymetrix microarrays. We pooled cells from 4 donor mice for each replicate, and used FACS to isolate pure populations of each inflammatory subset in parallel. We analyzed 3 T2M replicates and 2 replicates each of the other inflammatory subsets.

Project description:Time-dependent profiles were recapitulated in sorted neutrophils and Ly6Chigh and Ly6Clow muscle macrophages, with a distinct pro-resolving signature observed in Ly6Clow reparative macrophages. RNA-seq analysis of macrophages stimulated with resolvin D2 (RvD2) showed similarities to transcriptional changes found during the temporal Ly6Chigh to Ly6Clow phenotypic transition. Importantly, RvD2 promoted the temporal progression from Ly6Chigh to Ly6Clow macrophages in vivo.

Project description:Agonist-induced cardiac hypertrophy in TG1306/1R transgenic mice with cardiac angiotensin II overproduction leads to a gradual transition from a compensatory hypertrophic state to heart failure. To gain insight into the molecular mechanisms that play a role in maintaining cardiac integrity in the diseased heart, we performed a comparative study of gene expression between wild-type (WT) and transgenic (TG) hearts using microarray analysis. TG1306/1R transgenics were separated into two phenotypic groups (hypertrophic and dilated) based on morphological parameters (cardiac weight index and histology) and either a moderate (hypertrophic) or a high (dilated) upregulation of molecular markers for hypertrophy and failure, and compared to age and sex-matched wild-types. In this series, twelve 60 week old male TG1306/1R mice were separated into 3 groups: WT1-4= Four Wild-types TG1306/1R littermates genetically negative for the transgene (-/-) Hyp1-4= Four TG1306/1R mice heterozygote for the transgene (-/+) and developing a concentric hypertrophic phenotype* Dil1-4 = Four TG1306/1R mice heterozygote for the transgene (-/+) and developing a dilated cardiac phenotype* This series contains 4 biological replicates for the following triangulation: WT is compared to Hyp, WT is compared to Dil, and Hyp is compared to Dil. * For further information read: Domenighetti AA, Wang Q, Egger M, Richards SM, Pedrazzini T, Delbridge LM.

Project description:To investigate the transcriptional effects of CD177+ neutrophils on macrophages in spinal cord injuries (SCI), we adapted a co-culture system containing isolated neutrophils from Cd177 WT or KO mice post-SCI and bone marrow-derived macrophages (BMDMs). Each group had a biological repeat (n=3).

Project description:Atherosclerosis and nonalcoholic fatty liver disease (NAFLD) are leading causes of morbidity and mortality in the Western countries. NAFLD is an important independent risk factor for the development of atherosclerosis. The renin-angiotensin system (RAS) with its two main opposing effectors: angiotensin II (Ang II) and Ang-(1-7) is widely recognized as a major regulator of cardiovascular function and body metabolic processes. Angiotensin-converting enzyme 2 (ACE2) by breaking-down Ang II forms Ang-(1-7) and thus favors Ang-(1-7) actions. Therefore, the aim of our study was to comprehensively evaluate the influence of prolonged treatment with ACE2 activator – diminazene aceturate (DIZE) on the development of atherosclerotic lesions and hepatic steatosis in apoE-/- mice fed a high-fat diet (HFD). We have shown that DIZE at a dose of 30 mg/kg/day given orally for 16 weeks was able to stabilize atherosclerotic lesions and attenuate hepatic steatosis in apoE-/- mice fed an HFD. Such effects were associated with decreased total macrophages content and increased α-smooth muscle actin levels in atherosclerotic plaques. Moreover, DIZE changed polarization of macrophages towards increased amount of anti-inflammatory M2 macrophages in atherosclerotic lesions. Interestingly, the anti-steatotic action of DIZE in the liver was related to the elevated HDL in the plasma, decreased triglycerides levels and increased biosynthesis and concentration of taurine in liver of apoE-/- mice. However, the exact molecular mechanisms of both the anti-atherosclerotic and anti-steatotic actions of DIZE require further investigations.

Project description:The CCAAT/enhancer-binding proteins (CEBPs) are transcription factors involved in hematopoietic cell development and induction of several inflammatory mediators. Here, we generated CEBP-beta (CEBPB) and CEBP-epsilon (CEBPE) double-knockout (bbee) mice and compared their phenotypes to those of single-deficient (bbEE and BBee) and wild-type (BBEE) mice. The bbee mice were highly susceptible to fatal infections and died within 2-3 months. Morphologically, their neutrophils were blocked at the myelocytes/metamyelocytes stage, and clonogenic assays of bone marrow cells indicated a significant decrease in the number of myeloid colonies of the bbee mice. In addition, the proportion of hematopoietic progenitor cells [Lin(-)Sca1(+)c-Kit(+)] in the bone marrow of the bbee mice was significantly increased, reflecting the defective differentiation of the myeloid compartment. Furthermore, microarray expression analysis of lipopolysaccharide (LPS)- and interferon-gamma (IFN-gamma)-activated bone marrow-derived macrophages from bbee compared to single knockout mice revealed decreased expression of essential immune response-related genes and networks, including some direct CEBP targets such as Marco and Clec4e. Overall, the phenotype of the bbee mice is distinct from either the bbEE or BBee mice, demonstrating that both transcription factors are crucial for the maturation of neutrophils and macrophages, as well as the innate immune system, and can at least in part compensate for each other in the single knockout mice. To rule out the regulatory influence of both CEBPB and CEBPE on macrophage-related genes, expression analysis of bone marrow-derived macrophages was performed. Macrophages were derived from murine bone marrow with the use of murine M-CSF. The macrophages were stimulated with both LPS (100 ng) and IFN-gamma (100 ng) for 24h, and RNA was extracted for array analysis. Overall, RNA was extracted from stimulated macrophages of one WT mouse, one CEBPB-KO mouse, one CEBPE-KO mouse and one double-KO mouse.

Project description:A leucine-rich protein, ARR19 (androgen receptor corepressor-19 kDa), is highly expressed in male reproductive organs and moderately in others. Previously, we have reported that ARR19 is differentially expressed in adult Leydig cells during the testis development and inhibits steroidogenesis by reducing the expression of steroidogenic enzymes. Whereas in prostate, ARR19 represses the transcriptional activity of AR (androgen receptor), it is important for male sexual differentiation and maturation in prostate and epididymis, through the recruitment of HDAC4. In this study we show that long term adenovirus mediated overexpression of ARR19 in mice testis has the potential of inhibiting the differentiation of testicular and prostatic cells by reducing the size of testis and prostate but has no effect on the growth of seminal vesicles. Further, it reduces the level of progesterone and testosterone by reducing the steroidogenic enzymes such as 3HSD, P450c17 and StAR. This is the first study reporting a time-course analysis of the implications of long term overexpression of ARR19 in mice testis and its effect on other organs such as prostate and seminal vesicles. Taken together, these results suggest that ARR19 may play an important role in the differentiation of male reproductive organs such as testis and prostate.
