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.

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.

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.

Genome-wide analysis of impact of culture conditions on gene expression of primary leukemic cells from chronic lymphocytic leukemia (CLL)

Project description:Proliferation and survival of CLL cells is highly dependent on the interaction of the tumor cells with different populations of accessory cells, incl. mesenchymal bone marrow stromal cells. In this project interactions between CLL cells and transformed bone-marrow derived fibroblast cell lines were studied. Gene expression was analyzed in CLL cells that were cocultured for different time periods with human (HS-5) or murine (M2-10B4) transformed fibroblasts, as compared to CLL cells from the same patient sample that were cultured in DMEM medium or conditioned medium in which HS-5 cells had been growing.

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+).
