Project description:The function of ID4 in CLL development was studied in vivo using TCL1 transgenic mouse model that develop leukemia similar to human CLL. TCL1 mice with ID4 single knockout gene have accelerated CLL progression. Results from the animal study suggest ID4 as a tumor suppressor gene that might regulate cell proliferation and apoptosis in B lymphocytes. Gene expression in CD19-positive splenic B cells collected from 1-month old ID4+/-TCL1-tg and ID4+/+TCL1-tg mice was compared by microarray, the goal is to find ID4-regulated genes involved in CLL development.
Project description:mRNA profiles of Treg, CD4+, CD8+, CD19+ splenic cells from 8-week-old Foxp3 YFP/cre mice injected with control (WT) or leukemic (TCL1) extracellular vesicles (EV) were analyzed in triplicate.

Project description:Gene expression profile of splenic B cells (CD19+) from transgenic mice expressing the Epstein-Barr virus (EBV) latent membrane proteins (LMP) 1 and/or LMP2A. Freshly harvested primary B cells were profiled. B lymphocytes from transgenic LMP1, LMP2A, LMP1/2A mice and negative littermates were profiled from 6 month old adult mice; lymphoma cells were passaged in SCID mice and profiled for three LMP1 positive lymphomas and one negative lymphoma.

B lymphocytes from transgenic LMP1, LMP2A, LMP1/2A mice and negative littermates were profiled from 6 month old adult mice; lymphoma cells were passaged in SCID mice and profiled for three LMP1 positive lymphomas and one negative lymphoma. 12 total samples. 4 transgenic B lymphocyte samples pooled from multiple biological replicates were hybridized to duplicate microarrays: LMP1 (pooled from 2 replicates), LMP2A (pooled from 3 replicates); LMP1/2A (pooled from 5 replicates), negative littermates (pooled from 4 replicates). 3 biological replicates of LMP1 lymphomas expressing high, medium and low levels of LMP1 and; 1 negative lymphoma was hybridized to 1 microarray chip. The reference sample consisted of 4 biological replicates of splenic B cells (CD19+) pooled from 4-7 month old non-transgenic Balb/c mice. The same reference was used for all hybridizations.

Project description:Tcl1 tg mice develop a chronic lymphocytic leukemia (CLL) -like disease. To investigate the contribution of the adhesion molecule CD44 to CLL pathophysiology, we developed a CD19Cre CD44flox/flox Tcl1 tg mouse with a B cell specific CD44 deficiency (CD44ΔB Tcl1 tg). We used the Clariom S mouse microarray from Affymetrix to investigate transcriptional differeneces between Tcl1 tg and CD44ΔB Tcl1 tg mice
Project description:Transcription profiling of heart ventricles from 10 week old mice heterozygous for dn-p21ras and 3 month old wild type FVB mice to study severe dilated cardiomyopathy.
Project description:Transcriptome analysis of RNA samples from leukemia cells of ROR1xTCL1 and TCL1 transgenic mice Animals engrafted with ROR1xTCL1 leukemia-cells developed more aggressive disease than mice engrafted with TCL1 leukemia cells. Transcriptome analysis of RNA samples from leukemia ROR1xTCL1 transgenic mice revealed shared common gene expression signatures that were distinct from those of TCL1 leukemia-cells. We performed microarray transcriptome analyses on isolated leukemia cells that developed in ROR1xTCL1 Tg mice (n=4) or TCL1 Tg mice (n=4) using the Affymetrix Mouse Exon 1.0 ST platform. Array data was processed by Affymetrix Exon Array Computational Tool. No techinical replicates were performed.
