Gene expression of polyoma middle T antigen induced mammary tumors [AKXD x PyMT]

ABSTRACT: Mouse genetic crosses were established between the PyMT model of metastatic breast cancer and AKXD strain. Tumors were harvested from the animals for gene expression analysis to identify genes and network modules associated with progression to distant metastatic disease. Gene expression of 56 samples from the AKXD crosses were assayed on Affymetrix chips

Transformation of enriched mammary cell populations with Polyoma Middle T Antigen influences tumor subtype and metastatic potential

Project description:Breast cancer is a multifaceted disease, exhibiting significant molecular, histological, and pathological diversity. Factors that impact this heterogeneity are poorly understood; however, transformation of distinct normal cell populations of the breast may generate different tumor phenotypes. Our previous study demonstrates that the polyomavirus middle T antigen (PyMT) oncogene can establish diverse tumor subtypes when broadly expressed within mouse mammary epithelial cells. Herein, we assess the molecular, histological, and metastatic outcomes from distinct mammary cell populations transformed with PyMT. By combining several methodologies, including lentiviral infection, cell sorting, and transplantation, we have characterized tumors arising from enriched populations of mammary epithelial cells. We have found that expression of PyMT within different cell populations influences tumor histology, molecular subtype, and metastatic potential. 32 samples, 1 from each of 32 mouse mammary tumors arising from transplanted mouse mamary epithelial cells (MMECs) transduced with PyMT-expressing lentivirus. MMECs were sorted into four different types prior to transplant: luminal CD133+ (8 samples), luminal CD133- (11 samples), stem (6 samples), and basal (7 samples). The background for the cell donor and transplant recipients mice was FVB/NJ obtained from Jackson Laboratories.

Genetic deletion or pharmacologic blockade of the amino acid transporter Slc6a14 in mice suppresses breast cancer induced by Polyoma middle T oncogene

Project description:Tumor cells have an increased need for amino acids. Mammalian cells cannot synthesize essential amino acids; they must obtain these amino acids via specific transporters. Glutamine, though a non-essential amino acid, is critical for tumor cells (glutamine addiction). Entry of amino acids into tumor cells is enhanced by upregulation of specific transporters. If the transporters that are specifically induced in tumor cells are identified, blockade of the induced transporters would constitute a logical strategy for cancer treatment. The transporter SLC6A14 is unique and transports all essential amino acids as well as glutamine and is expressed only at low levels in normal tissues, but induced in colon cancer and in ER+ breast cancer. We have now established the potential of this transporter as a drug target for breast cancer treatment using genetic and pharmacologic approaches. We then examined the progression of breast cancer in Polyoma middle T antigen (Py-MT) Tg mouse on Slc6a14+/+ and Slc6a14-/- background using microarray analysis. We have used three Affy-chips for each tumor sample (Group 1: WT/PyMT; Group 2: Slc6a14-KO/PyMT). Three biological replicates were used for each group.

Characterization of Chemotherapy-treated PyMT Liver Matrisome

Project description:Metastasis accounts for 90% of cancer-related deaths, yet the mechanisms by which cancer cells colonize secondary organs remain poorly understood. For breast cancer patients, metastasis to the liver is associated with poor prognosis and a median survival of 6 months. Standard of care is chemotherapy, but recurrence occurs in 30% of patients. Systemic chemotherapy has been shown to induce hepatotoxicity and fibrosis, but how chemotherapy impacts the composition of the liver extracellular matrix (ECM) remains unknown. Individual ECM proteins drive tumor cell proliferation and invasion, features that are essential for metastatic outgrowth in the liver. Here, we characterize the liver ECM of tumor-bearing mice treated with and without chemotherapy using the MMTV-PyMT transgenic model of breast cancer. We identify distinct drug-specific changes induced by commonly used cytotoxic chemotherapies. We identify Collagen V as an ECM protein that is more abundant in livers isolated from paclitaxel-treated mice and identify mechanisms of Collagen V driven invasion via ECM organization and signaling through α1β1 integrins.
