RNA-Seq analysis comparing p53-null versus ΔNp63Δ/Δ;p53-null or ΔNp73Δ/Δ;p53-null thymic lymphoma tumors

Project description:We performed an RNA-Seq analysis comparing thymic lymphoma tissues from the p53-null(n=2) and ΔNp63Δ/Δ;p53-/- (n=3) or ΔNp73Δ/Δ;p53-/-(n=3). Mice at 10 weeks of age were injected with either Ad-mCherry or Ad-CRE-mCherry to delete ΔNp63/ΔNp73 in the thymic lmyphomas. We aimed to test by deleting the DNp63/DNp73 in these p53-deficient tumors will mediate tumor regression and analyze the expression profile of the genes

Transcription profiling of mouse CD71+/Ter-119+ bone marrow erythroid progenitors from Rb-null animals and controls reveals Rb intrinsically promotes erythropoiesis by coupling cell cycle exit with mitochondrial biogenesis

Project description:Regulation of the cell cycle is intimately linked to erythroid differentiation, yet how these processes are coupled is not well understood. To gain insight into this coordinate regulation, we examined the role that the retinoblastoma protein (Rb), a central regulator of the cell cycle, plays in erythropoiesis. We found that Rb serves a cell-intrinsic role and its absence causes ineffective erythropoiesis, with a differentiation block at the transition from early to late erythroblasts. Unexpectedly, in addition to a failure to properly exit the cell cycle, mitochondrial biogenesis fails to be upregulated concomitantly, contributing to this differentiation block. The link between erythropoiesis and mitochondrial function was validated by inhibition of mitochondrial biogenesis. Erythropoiesis in the absence of Rb resembles the human myelodysplastic syndromes, where defects in cell cycle regulation and mitochondrial function frequently occur. Our work demonstrates how these seemingly disparate pathways play a role in coordinately regulating cellular differentiation. Experiment Overall Design: Microarray expression analysis from sorted CD71+/Ter-119+ bone marrow erythroid progenitors of Rb-null animals and controls. The Rb-null genotype was EpoR-GFPcre/+; Rb fl/fl and the control genotype was EpoR-GFPcre/+; Rb fl/+. We have analyzed 3 Rb-null datasets and 3 control datasets.

Expression data from wildtype and Rb-/- fetal liver at e12.5

Project description:Rb null embryos exhibit defective fetal liver erythropoiesis. We used microarrays to compare Wt and Rb null fetal livers and to analyse gene expression differences which accompany and may underlie Rb null fetal liver degeneration, erythroid failure, and erythropoietic island dissolution. We used microarrays to compare Wt and Rb null fetal livers and analyse gene expression changes which accompany and may underlie fetal liver. Keywords: retinoblastoma, fetal liver, erythroblast, macrophage, cell death
