Transcription profiling of mouse mECK36: a cell and animal model of virally induced Kaposis sarcoma

ABSTRACT: Transfection of a Kaposi's sarcoma (KS) herpesvirus (KSHV) Bacterial Artificial Chromosome (KSHVBac36) into mouse bone marrow endothelial lineage cells generated a cell (mECK36) that induced KS-like tumors in mice. mECK36 formed KSHV-harboring vascularized spindle-cell sarcomas that were LANA+ and displayed a KSHV and host transcriptomes reminiscent of KS tumors. Experiment Overall Design: There are three biological replicates per sample. Tumors (mKS) were compared the the human KS signature. mECK36 and mEC-V were compared to putative BM lineage cells.

Transfection of a Kaposi's sarcoma (KS) herpesvirus (KSHV) Bacterial Artificial Chromosome (KSHVBac36) into mouse bone marrow endothelial-lineage cells generates a cell (mECK36) that forms KS-like tumors in mice. mECK36 expressed most KSHV genes and were angiogenic, but they didn't form colonies in soft agar. In nude mice, mECK36 formed KSHV-harboring vascularized spindle cell sarcomas that were LANA+/podoplanin+, overexpressed VEGF and Angiopoietin ligands and receptors, and displayed KSHV and ...[more]

Project description:Three major MAP kinase signaling cascades, ERK, p38 and JNK, play significant roles in the development of cardiac hypertrophy and heart failure in response to external stress and neural/hormonal stimuli. In order to study the specific function of each MAP kinase branch in adult heart, we have generated three transgenic mouse models with cardiac specific and temporally regulated expression of activated mutants of Ras, MKK3 and MKK7, which are selective upstream activators for ERK, p38 and JNK, respectively. Gene expression profiles in transgenic adult hearts were determined using cDNA microarrays at both early (4-7 days) and late (2-4 weeks) time points following transgene induction. From this study, we revealed common changes in gene expression among the three models, particularly involving extracellular matrix remodeling. However, distinct expression patterns characteristic for each pathway were also identified in cell signaling, growth and physiology. In addition, genes with dynamic expression differences between early vs. late stages illustrated primary vs. secondary changes upon MAP kinase activation in adult hearts. These results provide an overview to both short term and long term effects of MAP kinase activation in heart and support some common as well as unique roles for each MAP kinase cascade in the development of heart failure. Experiment Overall Design:MHC-floxed-HRas-v12/MKK3bE/MKK7D transgenic mice were bred with MHC-Mer-Cre-Mer (MCM) mice (from Dr. J. Molkentin, Cincinnati Children's Hospital) to generate double transgenic animals harboring both floxed transgenes and Mer-Cre-Mer transgene. At 12 weeks of age the double transgenic mice and non-transgenic littermate controls were treated via i.p. injection of tamoxifen at a dosage of 20mg/kgBW once a day for 3 consecutive days as reported. The hearts were harvested at an early (4-7 days post first tamoxifen injection) and a late (2-4 weeks) time point. Left ventricles were dissected and rapidly frozen in liquid nitrogen and stored at -80C prior to protein and RNA analysis. Transcription profiling of
