Affymetrix Human Genome U133A 2.0 Array (hgu133a2)
Description
Barretts esophagus (BE) is a metaplastic precursor lesion of esophageal adenocarcinoma (EA), the most rapidly increasing cancer in western societies. While the prevalence of BE is increasing, the vast majority of EA occurs in patients with undiagnosed BE. Thus, we sought to identify genes that are altered in BE compared to the normal mucosa of the esophagus, and which may be potential biomarkers for the development or diagnosis of BE.
Publication Title
Global changes in gene expression of Barrett's esophagus compared to normal squamous esophagus and gastric cardia tissues.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Mesenchymal stromal cells (MSC) were isolated from human bone marrow. Here, we have compared gene expression profiles of MSC at early and late passages and upon stimulation with transforming growth factor beta 1 (TGF-b1). Stimulation was performed with 1ng/mL TGF-b1 for 1, 4, or 12 hours as indicated. The goal of this study was to determine if senescence-associated gene expression changes and TGF-b1 induced gene expression changes are related.
Publication Title
TGF-beta1 does not induce senescence of multipotent mesenchymal stromal cells and has similar effects in early and late passages.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Multipotent progenitors (MPP) and common dendritic cell progenitors (CDP) were obtained from mouse bone marrow, followed by in vitro culture with a specific cytokine cocktail and FACS sorting (Felker et al., 2010; Ser et al., 2012). Cells were treated with 10 ng/ml recombinant human TGF-1 (R&D Systems, Minneapolis, USA) for 2, 4, 8, 12 and 24 h as described (Felker et al., 2010) or left untreated.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
We here compared gene expression profiles in HepG2 cells upon stimulation with 1 ng/ml TGF-beta1 for 20 min, 1 hour, 2 hours, 4 hours, and 24 hours with untreated control cells. Experiments were done in three independent replicates. The goal of this study was to determine genes regulated by TGF-beta1.HepG2 cells were obtained from DSMZ (Braunschweig, Germany) and cell identity confirmed by STR profiling using the AmpFlSTR Identfiler Direct PCR Amplification kit (Life Technologies, Darmstadt, Germany). Gene expression profiles were compared at indicated time points after stimulation with TGF-beta (1 ng/ml) using the Human Gene 1.0 ST arrays (Affymetrix). In total 18 hybridizations are included in this series.

Description
We here compared gene expression profiles of primary murine hepatocytes (mPC) upon stimulation with 1 ng/ml TGF-beta1 for 20 min, 2 hours and 4 hours with untreated cells. Experiments were done in three independent replicates. The goal of this study was to determine genes regulated by TGF-beta1.
