RNA-Seq analysis of LYN deficient stromal cells sorted from murine spleens

Project description:LYN kinase is a tyrosine kinase, that regulates cellular homeostasis in a context-specific manner. Our group could show, that its expression in the leukemic microenvironment of chronic lymphocytic leukemia contributes to disease progression (Nguyen PH et al.; Cancer Cell; 2016). We analyzed the effect of LYN deficiency on murine splenic stromal cells by FACS-sorting stroma cells from Lyn(wt/wt) and Lyn(-/-) spleen (7AAD-Cd45-Cd71-Cd31-Cd26+Cd54+).

Transcriptome of LYN deficient HS-5 stroma cells

Project description:LYN kinase is a tyrosine kinase, that regulates cellular homeostasis in a context-specific manner. Our group could show, that its expression in the leukemic microenvironment of chronic lymphocytic leukemia contributes to disease progression (Nguyen PH et al.; Cancer Cell; 2016). To analyze the effect of LYN kinase on the leukemia supportive phenotype of the bone marrow stromal cell line HS-5, we generated single cell clones of LYN deficient stroma cells. These cells were analyzed in a Multi-Omic approach, including microarray based analysis of the transcriptome.

Secretome of LYN deficient HS-5 stroma cells

Project description:LYN kinase is a tyrosine kinase, that regulates cellular homeostasis in a context specific manner. Our group could show, that its expression in the leukemic microenvironment of chronic lymphocytic leukemia contributes to disease progression (Nguyen PH et al.; Cancer Cell; 2016). To analyze the effect of LYN kinase on the leukemia supportive phenotype of the bone marrow stromal cell line HS-5, we generated single cell clones of LYN deficient cells. These cells were analyzed in a Multi-Omic approach, including quantitative, label-free proteomic analysis of the Secretome.

RNA-Seq analysis of LYN deficient HS-5 stroma cells cocultured with primary human CLL cells

Project description:LYN kinase is a tyrosine kinase, that regulates cellular homeostasis in a context-specific manner. Our group could show, that its expression in the leukemic microenvironment of chronic lymphocytic leukemia contributes to disease progression (Nguyen PH et al.; Cancer Cell; 2016). To analyze the effect of LYN kinase on the leukemia supportive phenotype of the bone marrow stromal cell line HS-5, we generated single cell clones of LYN deficient stroma cells. These cells were analyzed in a Multi-Omic approach, including ARNA-Seq of stromal cells after 72h of coculture with primary human chronic lymphocytic leukaemia (CLL) samples.

Stromal cells support the survival of human primary chronic lymphocytic leukemia (CLL) cells

Project description:In chronic lymphocytic leukemia (CLL), the tumor cells receive survival support from stromal cells through direct cell contact, soluble factors and extracellular vesicles. The tyrosine protein kinase Lyn, is aberrantly expressed in the malignant and stromal cells in CLL tissue. We therefore studied the role of Lyn in the EV-based communication and tumor support. We compared the Lyn-dependent EV release, uptake and functionality using Lyn-proficient and deficient stromal cells and primary CLL cells. Lyn-proficient cells caused a significantly higher EV release and EV uptake as compared to Lyn-deficient ones. Also, they induced stronger support of primary CLL cells. Proteomic comparison of the EVs from Lyn-proficient and deficient stromal cell highlighted 72 significantly differentially expressed proteins, many of which belonging to the extracellular matrix organization, such as collagen, nidogen, fibronectin and endosialin (CD248). CD248, a marker of certain tumors and of cancer associated fibroblast (CAF) was significantly depleted in Lyn-deficient HS-5 cells. A knockdown of CD248 in Lyn+ HS-5 cells resulted in a diminished B-CLL cells survival feeding capacity compared to wildtype or scrambled control cells. The presented data provide preclinical evidence, that the tyrosine kinase Lyn crucially influences the EV-based communication between stromal and primary B-CLL cells by raising the EV release and their concentration of functional molecules, such as endosialin.

Transcriptome analysis of peripheral blood from Lyn-deficient mouse SLE model lacking Ifnar1 or Irf5

Project description:To clarify the role of interferon regulatory factor 5 (IRF5) other than inducing type I interferons (IFNs) in the pathogenesis of systemic lupus erythematosus (SLE), we performed transcriptome analysis of peripheral blood from Lyn-deficient mice with concomitant Ifnar1 or Irf5 deficiency. The results of gene set enrichment analysis (GSEA) suggest that IRF5 is involved in the induction of not only IFN-inducible genes (ISGs) but also oxidative phosphorylation (OXPHOS)-related genes in the SLE pathogenesis.

Gene expression profiling in wild-type, Irf5-KO, Lyn-KO and Lyn/Irf5-DKO BMDCs unstimulated or stimulated with CpG-B ODN

Project description:To characterize the relationship between IRF5 and Lyn in innate immune responses at a genome-wide scale, we performed gene expression microarray analysis for wild-type (WT), Irf5-KO, Lyn-KO and Lyn/Irf5-DKO bone marrow-derived dendritic cells (BMDCs) with or without 6 h-stimulation with 150 nM CpG-B ODN. We extracted the transcripts that were upregulated by CpG-B ODN in WT BMDCs, further upregulated in Lyn-KO BMDCs and then downregulated in Lyn/Irf5-DKO BMDCs (fold change ≥ 2, false discovery rate < 0.05). When these 79 transcripts were sorted by their expression levels in Lyn-KO BMDCs, most of the top 20 genes (13 out of 20) were those encoding type I interferons (IFNs), indicating that Lyn particularly suppresses IRF5 induction of type I IFNs.
