View SamplesStem-cells and transformed cancer cells specifically express a polycomb repressive complex subtype, PRC4 which characteristically contains Sirt1 (Sirtuin-1), a NAD+ dependent class III histone deacetylase (HDAC) and Eed2 isoform as specific members. Analyzing the transcriptiome and methylome analysis of Sirt1 deficient murine ESCs (Sirt1-/- ESC), we demonstrate that these cells repressed specifically on some genomic imprinted and germ-line related genes.

View SamplesUsing two independently derived murine BXH2 cell lines, Ara-C resistant derivatives were developed by exposure to increasing concentrations of Ara-C. Microarray analysis comparing the Ara-C resistant cells to their Ara-C sensitive parental cell lines identified potential genes involved in Ara-C resistance.
Deoxycytidine kinase is downregulated in Ara-C-resistant acute myeloid leukemia murine cell lines.

View SamplesFz4 and Fz8 cooperate in regulating the branching morhpogenesis of the developing kidney during mouse embryonic development, hence determines the eventual kidney size.
Genetic mosaic analysis reveals a major role for frizzled 4 and frizzled 8 in controlling ureteric growth in the developing kidney.

View Samplesp65-/-Ras cells show delayed tumor formation in SCID mice. However, after prolonged latency, tumor formation was observed from these mice. To understand the changes of NF-kB regulated genes before and after tumor formation, RNA from p65+/+Ras, p65+/+RasTumor, p65-/-Ras, p65-/-RasTumor cells were isolated and microarray were performed.
NF-κB functions in tumor initiation by suppressing the surveillance of both innate and adaptive immune cells.

View SamplesSV40 large T antigen (TAg) contributes to cell transformation, in part, by targeting two well characterized tumor suppressors, pRb and p53. TAg expression affects the transcriptional circuits controlled by Rb and by p53. We have performed a microarray analysis to examine the global change in gene expression induced by wild-type TAg and TAg-mutants, in an effort to link changes in gene expression to specific transforming functions. For this analysis we have used enterocytes from the mouse small intestine expressing TAg. Expression of TAg in the mouse intestine results in hyperplasia and dysplasia. Our analysis indicates that practically all gene expression regulated by TAg in enterocytes is dependent upon its binding and inactivation of the Rb-family proteins.
Simian virus 40 T-antigen-mediated gene regulation in enterocytes is controlled primarily by the Rb-E2F pathway.
