Affymetrix Rat Genome U34 Array (rgu34a)
Description
Nitric oxide (NO) regulated pulmonary vascular function and structure, in part, via its effect on gene expression. We used microarrays to determine the up- and downregulated genes in rat pulmonary artery smooth muscle cells exposed to the NO donor S-nitrosoglutathione (GSNO) for 1, 2, and 4 hours.
Publication Title
Phosphodiesterase 3A expression is modulated by nitric oxide in rat pulmonary artery smooth muscle cells.

Description
Sca1+/cKit hematopoietic BMCs of hosts bearing instigating tumors (BPLER) promote the growth of responding (HMLER-HR) tumors that form with a myofibroblast-rich, desmoplastic stroma. BMCs from mice bearing Non-instigating tumors lack this ability

Description
To examine the effects of recombinant granulin on human mammary stromal fibroblasts, we cultured normal human mammary fibroblasts in the presence of recombinant human granulin (1ug/ml) or PBS every 24h for 6 days.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
We examined the transcriptional function of cyclin D1 in mouse development using two approaches. First, we queried association of cyclin D1 with the genome of E14.5 mouse embryos using ChIP-on-chip approach. We observed binding of cyclin D1 to several promoter regions. Second, we compared gene expression profiles between wild-type and cyclin D1-null retinas. We observed several transcripts with altered levels in cyclin D1-null organs.
Publication Title
Transcriptional role of cyclin D1 in development revealed by a genetic-proteomic screen.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The delicate interaction between cancer cells and the surrounding stroma plays an essential role in all stages of tumourigenesis. Despite the significance of this interplay, alterations in protein composition underlying tumour-stroma interactions are largely unknown. The aim of this study was to identify stromal proteins with clinical relevance in non-small cell lung cancer.
Publication Title
CD99 is a novel prognostic stromal marker in non-small cell lung cancer.

Description
BEAS-2B cells have been treated with low doses (20g/ml) of CSC for 4 months. As negative control BEAS-2B cells were treated with DMSO (the CSC solvent). Non-treated cells were cultivated in parallel.

Description
The study seeks to identify the epigenetic changes caused by exposure of to cigarette smoke condensate. To this goal human bronchial epithelial cells, BEAS-2B, were treated with 5-aza-2deoxycitidine and trychostatin A (5AzaC/TSA) subsequent to a chronic exposure (1 month) to cigarette smoke condensate (CSC). As negative control served BEAS-2B cells that were untreated or treated with CSC/DMSO for one month without the subsequent application of 5Aza/TSA.

Description
Because it excises thymine from GT mismatches, TDG was proposed to counter mutagenesis by 5-methylcytosine deamination. Yet, TDG was also observed to attack 5-methycytosine itself, making it a candidate DNA demethylase, and interactions with transcription factors implicated additional functions in gene regulation. Unlike other DNA glycosylases, TDG is essential for embryonic development. Fibroblasts from Tdg null embryos show massively impaired gene regulation, and this correlates with imbalanced histone modification and CpG methylation. TDG associates with the promoters of affected genes in MEFs and in embryonic stem cells, but epigenetic aberrations appear only in differentiated cells. TDG also contributes to the maintenance of active and bivalent chromatin during cell differentiation, using its DNA glycosylase activity to counter aberrant de novo methylation. Thus, TDG dependent DNA repair stabilizes epigenetic states during cell differentiation.
Publication Title
Embryonic lethal phenotype reveals a function of TDG in maintaining epigenetic stability.
