Project description:We performed expression profiling of prostates of 3 month wild-type and PTEN NULL mice and assessed the response to 3 days of castration. Seven three month old WT and PbCre x PTEN f/f (PTEN NULL) mice were used. They are in the C57B6 background. Three mice in each group were castrated. Three days after castration, the prostate were harvested and RNA isolated by standard protocols and analyzed by expression profiling.

Project description:We performed expression mouse profiling of prostates of 3 month WT, ERG, PTEN f/f and Pten f/f;ERG mice. For WT and ERG prostates, entire prostates were dissected and total RNA immediated harvested. For Pten f/f and Pten f/f;ERG prostates, the Ventral Lobe was dissected.

Project description:We created mice, which are deficient for Myc specifically in cardiac myocytes by crossing crossed Myc-floxed mice (Mycfl/fl) and MLC-2VCre/+ mice. Serial analysis of earlier stages of gestation revealed that Myc-deficient mice died prematurely at E13.5-14.5. Morphological analyses of E13.5 Myc-null embryos showed normal ventricular size and structure; however, decreased cardiac myocyte proliferation and increased apoptosis was observed. BrdU incorporation rates were also decreased significantly in Myc-null myocardium. Myc-null mice displayed a 3.67-fold increase in apoptotic cardiomyocytes by TUNEL assay. We examined global gene expression using oligonucleotide microarrays. Numerous genes involved in mitochondrial death pathways were dysregulated including Bnip3L and Birc2. Keywords: wildtype vs Myc-null

Project description:KLF5 is a basic transcription factor that regulates multiple biological processes, but its function in tumorigenesis appears contradictory in the current literature, with some studies showing tumor suppressor activity and others showing tumor promoting activity. In this study, we examined the function of Klf5 in prostatic tumorigenesis using mice with prostate specific deletion of Klf5 and Pten, both of which are frequently deleted in human prostate cancer. Histological and molecular analyses demonstrated that when one Pten allele was deleted, which causes mouse intraepithelial neoplasia (mPIN), Klf5 deletion accelerated the emergence and progression of mPIN. When both Pten alleles were deleted, which causes prostate cancer, Klf5 deletion promoted tumor growth and caused more severe morphological and molecular alterations, and homozygous deletion of Klf5 was more effective than hemizygous deletion. Unexpectedly, while Klf5 deletion clearly promoted tumorigenesis in luminal cells, it actually diminished the numbers of Ck5-positive basal cells in the Pten-null tumors. Klf5 deletion also increased the cell proliferation rate in tumors with Pten deletion, which involved extensive activation of the PI3K/AKT and MAPK mitogenic signaling pathways and inactivation of the p15 cell cycle inhibitor. Global gene expression and pathway analyses demonstrated that multiple mechanisms could be responsible for the tumor promoting effect of Klf5 deletion, We used microarrays to detail the global programme of gene expression of Klf5-wildtype and Klf5-null mouse dorsal prostates under Pten-null context to figure out the differential expression profiling underlying tumorigenesis 4 Klf5-wildtype and 4 Klf5-null mouse (6 months age) dorsal prostates under Pten-null context were used for RNA extraction and hybridization on Affymetrix mouse st 1.0 array
