Transcription profiling of human MALT lymphoma and chronic gastritis tissue from the same patients

ABSTRACT: 21 Tissue samples of gastric MALT lymphoma were compared by cDNA microarray studies with chronic gastritis tissues from the same patient. From each patient, multiple mucosal biopsies of the stomach were taken both from i) the macroscopically infiltrated area and ii) distant from the lymphoma. For conventional histological examination, biopsies taken from the same areas were formalin fixed, embedded in paraffin and reviewed by a central pathologist. All lymphoma samples were tested by RT-PCR for t(11;18). None of them was t(11;18) positive.

INSTRUMENT(S): 418 [Affymetrix]

ORGANISM(S): Homo sapiens

DISEASE(S): chronic gastritis

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 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.

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.
