Gene expression profiling of patients from the Danish Center for Translational Breast Cancer Research program

ABSTRACT: Female breast cancer patients who underwent surgery for breast cancer as part of the Danish Center for Translational Breast Cancer Research program were included from 2003 to 2012. Patient inclusion criteria were: (1) a unifocal tumor with an estimated size of more than 20 mm in diameter, (2) none of the patients had a history of breast surgery and (3) none received preoperative treatment. Patients were defined as high risk according to the Danish Breast Cooperative Group (www.dbcg.dk) and were followed after surgery.

The tumor microenvironment is composed of many immune cell subpopulations and is an important factor in the malignant progression of neoplasms, particularly breast cancer (BC). However, the cytokine networks that coordinate various regulatory events within the BC interstitium remain largely uncharacterized. Moreover, the data obtained regarding the origin of cytokine secretions, the levels of secretion associated with tumor development, and the possible clinical relevance of cytokines remain con ...[more]

Project description:Direct induction of induced hepatocytes (iHeps) from fibroblasts holds potential as a strategy for regenerative medicine, but until now has only been shown in culture settings. Here, we describe in vivo iHep formation using transcription factor induction and genetic fate tracing in mouse models of chronic liver disease. We show that ectopic expression of the transcription factors FOXA3, GATA4, HNF1A and HNF4A from a polycistronic lentiviral vector converts mouse myofibroblasts into cells with a hepatocyte phenotype. In vivo expression of the same set of transcription factors from a p75 neurotrophin receptor peptide (p75NTRp)-tagged adenovirus enabled the generation of hepatocyte-like cells from myofibroblasts in fibrotic mouse livers and reduced liver fibrosis. We have therefore been able to convert profibrogenic myofibroblasts in the liver into hepatocyte-like cells with positive functional benefits. This direct in vivo reprogramming approach may open new avenues for the treatment of chronic liver disease. Whole Mouse Genome Oligo Microarray v2 (4x44K) (Agilent Technologies) was used to characterize global gene expression profiles of iHeps compared to myofibroblasts and primary mouse hepatocytes. All microarrays were performed at the Research Core Unit Transcriptomics of the Hanover Medical School. Briefly, total RNA was used to prepare the aminoallyl-UTPmodified (aaUTP) cRNAs (Amino Allyl MessageAmpâ¢ II Kit; #AM1753; Life Technologies) as directed by the company. The aaUTP-cRNAs were labelled with Alexa Fluor 555 Reactive Dye (#A32756; LifeTechnologies). Prior to the reverse transcription reaction, 1Î¼l of a 1:5000 dilution of Agilentâs One-Color spike-in Kit stock solution (#5188-5282, Agilent Technologies) was added to 100ng of total RNA of each analyzed sample. The cRNA fragmentation, hybridization, and washing steps were carried out according to Agilentâs One-Color Microarray-Based Gene Expression Analysis Protocol V5.7 except that 500ng of each labelled cRNA sample were used for hybridization. Slides were scanned on the Agilent Micro Array Scanner G2565 CA (pixel resolution 5 Î¼m, bit depth 20). Data extraction was performed with the Feature Extraction Software V10.7.3.1. 12 samples were analyzed: Pr-mHSC: Primary myofibroblasts derived from hepatic stellate cells (HSCs), 2 replicates; In-vivo iHep: In-vivo myofibroblasts-derived from induced hepatocytes (iHep), 3 replicates; In-vivo eHep: In-vivo endogenous hepatocytes (eHep), 3 replicates; In-vitro iHep: In-vitro myofibroblasts-derived from induced hepatocytes (iHep), 3 replicates; PH24h: Primary hepatocytes (PH) cultured for 24 hours, 1 replicate.
