Transcription profiling of human BJ fibroblasts after LIN-9 depletion by a shRNA

ABSTRACT: Aim: identification of differentially expressed genes after LIN-9 depletion.

hTERT immortalized human BJ fibroblasts were infected with pMSCV-Blasticidin based retroviruses encoding a shRNA which targets human LIN-9 and the empty vector respectively.
After 4 days of selection total RNA was isolated. Cy3 and Cy5 labelled cDNA probes were generated using the CyScribe Post-labelling Kit (Amersham Biosiences).

The human synMuv-like protein LIN-9 is required for transcription of G2/M genes and for entry into mitosis.

Regulated gene expression is critical for the proper timing of cell cycle transitions. Here we report that human LIN-9 has an important function in transcriptional regulation of G2/M genes. Depletion of LIN-9 by RNAi in human fibroblasts strongly impairs proliferation and delays progression from G2 to M. We identify a cluster of G2/M genes as direct targets of LIN-9. Activation of these genes is linked to an association between LIN-9 and B-MYB. Chromatin immunoprecipitation assays revealed bindi ...[more]

Transcription profiling time series of mouse melanocytes transfected with an inducible version of the oncogenic receptor Xmrk, starved for 72 h and afterwards stimulated with EGF

Project description:Signaling pathways specifically induced by the oncogenic receptor Xmrk can be elucidated by comparing gene expression in cells with the activated receptor to gene expression in cells with the non-activated receptor. Mouse melanocytes transfected with an inducible version of the oncogenic receptor Xmrk, were starved for 72 h and afterwards stimulated with EGF. We compared cells stimulated for 15 minutes, 1 h, 2 h, 4 h, 8 h or 24 h, respectively, to unstimulated cells.

Transcription profiling of human Soas-2 cells infected with adenoviruses expressing p53 proteins with charge-neutralizing or charge-inverting mutations in the H1 helix to investigate the role of the dimerization interface in p53 function

Project description:To investigate the role of the dimerization interface for p53 function, we introduced modest charge-neutralizing (R181→L "EL") and more severe charge-inverting (R181→E "EE" and E180→R, R181→E "RE") mutations into the H1 helix of the full-length p53 molecule. To characterize the nuclear transcriptional function of p53 mutants in an unbiased manner we employed gene expression profiling using cDNA microarrays. Saos-2 cells were infected with adenoviruses expressing the p53 proteins EE, EL, WT and RE which span the entire spectrum of apoptotic activity. Total cellular RNA was isolated 18 hours after infection when apoptosis had not yet occurred.

Transcription profiling of mouse splenic B cells expressing a dominant-negative p300 allele which lacks histone acetyltransferase activity

Project description:The p300 protein is one of more than 15 known mammalian HATs. We have used mice that carry a mutant allele of the p300 gene, which encodes a full-length protein that, however, lacks detectable acetyltransferase (AT)-activity and that acts in a dominant-negative manner. In addition, the allele is conditional, so that it can be expressed in a tissue-specific manner with the help of mice that express Cre-recombinase. Expression of the mutant allele specifically in B-cells, using CD19-cre mice, results in premature death with full penetrance from an autoimmune disease that closely mimics systemic lupus erythematosus (SLE) in its pathological manifestations.

Transcription profiling of human benign and malignant pheochromocytomas

Project description:Total RNA was isolated from fresh-frozen tissue of 5 benign and 5 malignant pheochromocytomas. The reference consisted of laser microdissected (LMD) tissue from normal adrenal medullae from 10 different patients. After generating Cy3- and Cy5-fluorescently labeled cDNAs, F-chips containing 11,540 spots were hybridized. Data were analyzed with the IMAGENE 3.0 software.

Transcription profiling of blood vessel endothelial cells from wild type and PPARb knock-out mice

Project description:To elucidate the mechanisms underlying the perturbation of tumor vascularization in Pparb/ mice we performed matrigel plug assays23. Matrigel containing prostaglandin E2 (PGE2) and basic fibroblast growth factor (FGF-2) was injected subcutaneously into both wild-type and Pparb/ mice where it formed semi-solid plugs. These plugs became rapidly invaded by AQP-1 positive cells. To analyze differences between Pparb+/+ and Pparb/ samples we compare the gene expression profile of both samples by microarray analysis.

Transcription profiling of mouseB-cell lymphomas with defined genetic alterations in p53 or p73

Project description:Induction of apoptosis by the tumor suppressor p53 is known to protect from Myc-driven lymphomagenesis. The p53 family member p73 is also a pro-apoptotic protein, which is activated in response to oncogenes like Myc. We therefore investigated whether p73 provides a similar protection from Myc-driven lymphomas as p53. To generate B-cell lymphomas with defined genetic alterations in p53 or p73, we crossed the Eµ-Myc transgenic to mice heterozygous for germ-line deletions in p53 (p53+/) or p73 (p73+/-). Lymphomas which have spontaneously developed in Eµ-Myc transgenic animals with the genotypes p53+/+, p53+/-, p73+/+, p73+/- or p73-/- were isolated when the animals were moribund and further processed for gene expression profiling with 22.5K cDNA microarrays.
