Gene expression of polyoma middle T antigen induced mammary tumors [NZB x PyMT]. Mus musculus

Mouse genetic crosses were established between the PyMT model of metastatic breast cancer and NZB strain. Tumors were harvested from the animals for gene expression analysis to identify genes and network modules associated with progression to distant metastatic disease. Overall design: Gene expression of 68 samples from the NZB crosses were assayed on Affymetrix chips
