RNA-seq of murine spleen B-cells after pentanoate treatment compared to untreated control

ABSTRACT: We tested the influence of pentanoate on B cells by treatment of CpG-stimulated B cells in vitro. We isolated naive B cells from FIR/TIGER mice (IL-10 (GFP) - Foxp3 (RFP) - Reporter mice) from spleen. Cells were cultured in presence of 5 µg/ml CpG 2395. 24h after CpG-stimulation, B cells were treated with 5 mM pentanoate or left untreated. Cells were harvested on day 4 after seeding.

Short-chain fatty acids (SCFAs) have immunomodulatory effects, but the underlying mechanisms are not well understood. Here we show that pentanoate, a physiologically abundant SCFA, is a potent regulator of immunometabolism. Pentanoate induces IL-10 production in lymphocytes by reprogramming their metabolic activity towards elevated glucose oxidation. Mechanistically, this reprogramming is mediated by supplying additional pentanoate-originated acetyl-CoA for histone acetyltransferases, and by pen ...[more]

RNA-seq of murine CD4 T cells after pentanoate treatment compared to untreated control

Project description:To analyse the influence of pentanoate on the differentiation of naive CD4 T cells under Th17 inducing conditions, murine CD4 T cells were isolated from spleen and lymphnodes of FIR/TIGER mice (IL-10 (GFP) - Foxp3 (RFP) - Reporter mice). The T cells were kept for 3 days under Th17 inducing conditions either with 4 mM pentanoate or without pentanoate (control).

FIR inhibition in HCC cells (Hep3B)

Project description:siRNA-mediated inhibition compared to untreated cells and cells transfected with nonsense siRNA Together with far upstream element binding protein (FBP), the FBP-interacting repressor (FIR) represents a molecular tool for the transcriptional fine tune regulation of target genes. Previous evidence indicates that strong overexpression of FBP in human hepatocellular carcinoma (HCC) supports tumor growth and correlates with poor patient prognosis. However, the role of the transcriptional repressor FIR in hepatocarcinogenesis remains poorly delineated. We show that overexpression of FIR correlates with tumor dedifferentiation and tumor cell proliferation in about 60% of primary HCCs. Elevated FIR levels are associated with genomic gains of the fir gene locus at chromosome 8q24.3 in human HCC specimens. In vitro, nuclear enrichment of FIR supports HCC cell proliferation and migration. Expression profiling of HCC cells after siRNA-mediated silencing of FIR identified the transcription factor DP-1 (TFDP1) as a transcriptional target of FIR. Surprisingly, FIR stimulates the expression of FBP in a TFDP1/E2F-dependent manner. FIR splice variants lacking or containing exon 2 and/or exon 5 are expressed in the majority of HCCs. Specific inhibition of FIR isoforms with and without exon 2 revealed that all FIR splice variants facilitate tumor-supporting effects. This finding was confirmed in xenograft transplantation experiments with lentiviral-infected shRNA targeting all FIR variants as well as FIR with and without exon 2. In summary, high-level nuclear FIR does not facilitate repressor properties but supports tumor growth in HCC cells. Thus, the pharmacological inhibition of FIR might represent a promising therapeutic strategy for HCC patients.

Choice of infection or immunity: microarrays analysis of the mechanism of CpG DNA enhancing the immune response on BMDCs pulsed with H9N2 AIV

Project description:Dendritic cells (DCs), professional antigen presenting cells, have demonstrated effective in controlling the initial of innate immune and enhancing immune response of vaccination, also proved that adjuvant CpG could improve the performance of immune system.Although exist many studies concerning the downstream response of DCs pulsed with CpG, rarely research gaze the interaction of DCs co-stimulated with CpG/H9N2 or CpG/inactivated H9N2 To explore the underlying molecular basis, we compared different stimulated mouse DCs with systemic approach microarrays The cultured mouse BMDCs were randomly divided into 6 groups (1: control DCs group, 2:CpG stimulated group, 3: H9N2 stimulated group, 4: CpG/H9N2 co-stimulated group, 5: inactivated H9N2 stimulated group, 6: CpG/inactivated H9N2 co-stimulated group). we used microarray to reveal striking transcriptome differences of different stimulated DCs.

Functional characterisation of CpG islands in mouse tissues

Project description:Tissue-specific methylation patterns suggest a role for CpG island (CGI) methylation in differentiation and cell-type-specific gene regulation. We have applied CXXC affinity purification (CAP), MBD affinity purification (MAP) and chromatin immunoprecipitation (ChIP) in combination with solexa sequencing to investigate the extent and functional significance of CGI methylation in mouse sperm, blood, cerebellum and ES cells.

Itch Ubiquitin Ligase Deficiency and B cell LC-MSMS

Project description:The E3 ubiquitin ligase Itch regulates antibody levels and prevents autoimmune disease in humans and mice, yet how Itch regulates B cell fate or function is unknown. We now show that Itch directly limits B cell activity. Using LC-MSMS, we profiled and compared the whole cell proteomes of Itch deficient and Itch sufficient CpG-stimulated B cells. B cells lacking Itch exhibited increased levels of mTORC1 targets and E2F transcription factor targets. These results support a novel role for Itch in limiting B cell metabolism and proliferation.

Ablation of casein kinase 1 in keratinocytes induces p53-dependent hyperpigmentation of the skin

Project description:To characterize the role of CK1 (encoded by Csnk1a1) in skin physiology, we crossed mice with floxed Csnk1a1 with mice expressing K14CreERT2 to generate mice in which tamoxifen induces the deletion of Csnk1a1 exclusively in keratinocytes (SKO). In addition, we established K14CreERT2 CK1/p53 double-knockout (DKO) to analyze the effect of coablation of both genes. 4-hydroxy-Tamoxifen was applied for 14 days to induce the deletion of CK1 and/or p53 in the epidermis of the mice. In addition, wild type mice where exposed to UVB irradiation to compare the effect of CK1a ablation with the effects of normal UV exposure. In comparison, we analyzed also wild type mice as reference. RNA was obtained from cells derived from mouse ear dorsal-epidermis and tail skin. Subsequently, we performed RNA sequencing and transcriptome analysis.
