Project description:To investigate the roles of Klf3 in B lymphopoiesis, CD19+ B cells were sorted from the spleens of WT and Klf3 KO mice (Molecular and Cellular Biology (2008); 28:3967–3978). Following RNA extraction, gene expression was compared in WT and Klf3 KO CD19+splenic B cells using Affymetrix microarrays.

Following RNA extraction, gene expression was compared in WT and Klf3 KO CD19+splenic B cells using Affymetrix microarrays. 4 wildtype and 4 Klf3 KO mice were analysed, aged between 10 and 12 weeks
Project description:Gene expression analysis of splenic follicular B cells and marginal zone B cells from B6 and CD19:KLF3 transgenic mice Comparing KLF3-transgenic and non-transgenic follicular B cells by RNA-microarray revealed that KLF3 regulates a subset of genes that was similarly up-/downregulated upon normal MZ B cell differentiation. Indeed, KLF3 expression overcame the lack of MZ B cells caused by different genetic alterations, such as CD19-deficiency or blockade of B-cell activating factor (BAFF)-receptor signaling, indicating that KLF3 may complement alternative NF-κB signaling. Thus, KLF3 is a driving force towards MZ B cell maturation. RNA of splenic follicular B cells and marginal zone B cells were obtained from 4 different mice per group (B6 and CD19:KLF3 mice). 16 samples = 8 individual mice x 2 B cell subsets.

Project description:Splenic B cells isolated from SCAP+/+ CD19-Cre (WT) and SCAPfl/fl CD19-Cre (KO) mice were stimulated with LPS or anti-CD40 for 24 and 48 hours. Cells were then analyzed by metabolomics. Metabolomics reveals global metabolic changes in SCAP deficient B cells.
Project description:To understand the mechanisms through which JunB regulates Tregs-mediated immune regulation, we examined the global gene expression profiles in the JunB WT and KO Tregs by performing RNA sequencing (RNA-seq) analysis.
Project description:The aim of this study was to analyze the transcriptome of TER119+ fetal liver cells in the absence of the transcription factor KLF3 at murine embryonic day E14.5 Three wildtype (WT; Klf3+/+) and three knockout (KO; Klf3-/-) samples
