Genome-wide analysis of gene expression in murine breast fibroblasts from normal tissue, hyperplasia, adenoma and carcinoma (MMTV-PyMT model). Mus musculus

Analysis of differences at gene expression level of hpvE6 immortalized fibroblasts isolated from normal mammary glands and from hyperplasia, adenoma and carcinoma stages using the MMTV-PyMT model (FVB/N background). Analysis demonstrated the activation of specific transcriptional programs in fibroblasts from later stages. Overall design: Total RNA obtained from isolated hpvE6 immortalized fibroblasts from normal mammary gland (NF) and from different stages of tumour development using the MMTV-PyMT murine breast cancer model. Stages were hyperplasia (HpAF), adenoma (AdAF) and carcinoma (CAF). Fibroblasts were seeded in a deformable Matrigel:collagen I matrix and total RNA isolated 72h later.
