Project description:RNA-sequencing analysis of liver gene expression after combinatorial liver-specific deletion of tumor suppressor genes in a mouse fatty liver disease and liver cancer model. Gene expression was determined at 16 weeks of age, before onset of liver tumor formation. Aim was to study how loss of atypical E2F transcription repressors affected gene expression in Pten-mutant livers.
Project description:We used microarrays to analyze the global gene expression and identified differentially expressed gene list between wild-type anterior prostates and Pb-Cre4;PtenLoxP/LoxP anterior prostates, Pb-Cre4;PtenLoxP/LoxP;LrfLoxP/LoxP anterior prostates at 12 weeks of age. Prostate-specific Pten deletion (Pb-Cre4;PtenLoxP/LoxP) results in prostate intraepithelial neoplasia (PIN) which, following a long latency, can progress to high-grade adenocarcinoma, albeit with minimally invasive and metastatic features. However, inactivation of Lrf in the prostate epithelium in combination of Pten results in aggressive prostate tumors. To understand the molecular mechanisms by which loss of Lrf promotes Pten-loss-driven prostate tumorigenesis, we conducted transcriptome comparison of three wild-type anterior prostates, three Pb-Cre4;PtenLoxP/LoxP PIN, and three Pb-Cre4;PtenLoxP/LoxP;LrfLoxP/LoxP anterior prostate tumors.
Project description:We used microarrays to detail the global gene expression and identified differentially expressed gene list between wild-type anterior prostates and Ptenpc-/- anterior prostates, Ptenpc-/-Smad4pc-/- and Ptenpc-/- anterior prostates, Ptenpc-/-p53pc-/- and Ptenpc-/- anterior prostates at 15 weeks of age. Prostate-specific Pten deletion (Ptenpc-/-) results in prostate intraepithelial neoplasia (PIN) which, following a long latency, can progress to high-grade adenocarcinoma, albeit with minimally invasive and metastatic features. To understand this feeble progression phenotype, we conducted transcriptome comparison of five Ptenpc-/- PIN relative to three wild-type anterior prostate. Moreover, Ptenpc-/-Smad4pc-/- progress to metastasis, while Ptenpc-/-p53pc-/- not progress to metastasis. To understand this phenotype difference, we conducted transcriptome comparison of five Ptenpc-/-Smad4pc-/-to five Ptenpc-/- prostate tumor, and three Ptenpc-/-p53pc-/- to five Ptenpc-/- tumor.
Project description:Mice with (i) PR-Cre; (ii) PR-Cre, Fbxw7 R482Q/+; (iii) PR-Cre, Pten fl/fl; (iv) PR-Cre, Pten fl/fl, Fbxw7 R482Q/+ Uterine RNA was harvested at 8 weeks age and expression profiling done by Affymetrix Clariom S Mouse HT array
Project description:RNA-seq was carried out on prostate tumors from mice with prostate-conditional PTEN knockout with and without prostate-conditional FOXP1-SHQ1 locus deletion (12 month old PTEN-flox/flox Pb-Cre4 mice and FOXP1-SHQ1-flox/flox PTEN-flox/flox Pb-Cre4 mice )
Project description:Single cell RNA-seq data was obtained from FACS sorted microglia from different brain regions of normal embryonic, 3 weeks and 16 weeks old CD1 mice in order to elucidate microglia heterogeneity in a regional and time specific manner.
Project description:We used microarrays to detail the global gene expression and identified differentially expressed gene list between wild-type anterior prostates and Ptenpc-/- anterior prostates, Ptenpc-/-Smad4pc-/- and Ptenpc-/- anterior prostates, Ptenpc-/-p53pc-/- and Ptenpc-/- anterior prostates at 15 weeks of age.
Project description:Triple transgenic mice harboring a conditional Pten allele were developed and Pten was conditionally deleted in vivo from the lung epithelial cells using the doxycycline dependent Cre/LoxP approach. Microarray analysis of lung RNA isolated from Pten-deleted lung epithelial cells (PtenΔ/Δ) and control mice was performed to identify potential PTEN responsive genes.
