(Submitter supplied) Although ERBB2 amplification and overexpression is correlated with poor outcome in breast cancer, the molecular mechanisms underlying the aggressive nature of these tumors has not been fully elucidated. To investigate this further, we have used a transgenic mouse model of ErbB2-driven tumor progression (ErbB2KI model) that recapitulates clinically relevant events, including selective amplification of the core erbB2 amplicon. more...

Analysis of mammary glands of 5 and 10-week-old bitransgenics overexpressing oncogenic ErbB2/Neu and luteinizing hormone (LH). Results provide insight into the effect of chronic trophic maintenance of the mammary epithelial cells, induced by LH, on ErbB2/Neu-initiated tumorigenesis.

(Submitter supplied) Previously we have demonstrated that inactivation of retinoic acid receptor beta (Rarb) in the mouse results in a protective effect against ErbB2-induced mammary gland tumorigenesis although Rarb has been reported as a tumor suppressor before. In the current study, we further confirmed that ablation of Rarb has a very similar impact on Wnt1-induced mammary gland tumorigenesis as those on ErbB2-induced mammary gland tumorigenesis. more...

(Submitter supplied) The fibroblast growth factor pathway is known to cooperate with the highly oncogenic Wnt/beta-catenin pathway in mouse models of breast cancer. To investigate the mechanisms involved in this cooperativity, we utilized MMTV-driven transgenic mouse lines expressing a drug-inducible model for FGF Receptor signaling (iFGFR) crossed with the previously characterized MMTV-Wnt-1 mouse model. In these bigenic mice, both iFGFR1 and iFGFR2 activation resulted in a dramatic enhancement of mammary tumorigenesis. more...

(Submitter supplied) Pygopus2 (Pygo2), a co-activator of Wnt/ β-catenin signaling can also bind H3K4me2/3 and participate in chromatin reading and writing. To investigate the functional relevance of histone binding activity of Pygo2 in malignant progression of breast cancer, we generated a knockin mouse model wherein binding of Pygo2 to H3K4me2/3 was rendered ineffective. Loss of Pygo2-histone binding resulted in smaller, differentiated and less metastatic tumors, at least in part due to a decrease in Wnt/ b-catenin signaling. more...

(Submitter supplied) To understand the mechanisms by which mast cells affect the features of breast cancer cells, we collected spontaneous mammary tumors from MMTV-PyMT mice, C57BL/6 wild type or back-crossed with Wsh mice which lack mast cells. Gene expression profiling was performed to select the genes which are differentially expressed in the presence or absence of mast cells.

(Submitter supplied) Understanding the mechanisms underlying tumor heterogeneity is key to development of treatments that can target specific tumor subtypes. We have previously targeted CRE recombinase-dependent conditional deletion of the tumor suppressor genes Brca1, Brca2, p53 and/or Pten to basal or luminal ER- cells of the mouse mammary epithelium. We demonstrated that both the cell-of-origin and the tumor-initiating genetic lesions co-operate to influence mammary tumor phenotype. more...

(Submitter supplied) Hepatocytes are highly polarized epithelia. Loss of hepatocyte polarity is associated with various liver diseases, including cholestasis. However, the molecular underpinnings of hepatocyte polarization remain poorly understood. Previously, we have shown that loss of β-catenin at adherens junctions (AJs) is compensated by β-catenin and dual loss of both catenins in dual knockouts (DKO) in mice liver leads to progressive intrahepatic cholestasis. more...
