(Submitter supplied) Skin-mammary specific knockout (SSKO) of Pygo2 (K14-cre; Pygo2 flox/-) , a WNT signaling co-activator, results in defective mouse mammary gland development. The FACS sorted mammary stem cell (MaSC)/basal population from Pygo2 SSKO mammary gland displays biased differentiation towards luminal/alveolar lineage in vitro, and reduced regeneration rate of new mammary gland in vivo

(Submitter supplied) A transgenic mouse model, MMTV-Wnt/ILK, with mammary specific expression of both Wnt-1 and ILK, was generated by crossing the two mouse lines MMTV-Wnt-1 and MMTV-ILK. Affymetrix Mouse Exon chips were hybridized with material from four independent mammary tumors from each MMTV-Wnt-1 and MMTV-Wnt/ILK transgenic model, in order to identify possible signaling differences involved during increased tumor incidence.

(Submitter supplied) The goal of the study was to compare gene expression of Robo1+/+ and Robo1-/- luminal progenitors. Total RNAs were then extracted from FACS purified luminal progenitor cells, harvested from Robo1+/+ or Robo1-/- mice (n=3 per genotype, two animals per n) using TRIreagent LS (Sigma, T3934). Poly(A)+ RNA sequencing libraries were made from each sample using the TruSeq RNA library preparation kit v.1 (Illumina). 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) Chromosomal translocations juxtaposing the androgen-responsive TMPRSS2 promoter with the ETS-family transcription factor ERG result in aberrant ERG up-regulation in approximately 50% of prostate cancers. Studies to date have demonstrated important roles of ERG in inducing oncogenic properties of prostate cancer. Its molecular mechanisms of action, however, are yet to be fully understood. To address these questions, we generated engineered LNCaP cells with ERG overexpression followed by LEF1 knockdown as well as control cell lines. more...

(Submitter supplied) Investigation of whole-genome gene expression level changes in C57Bl6 Lrp5-/- mammary epithelial cells, compared to the wild-type strain. The mammary epithelial cells were isolated from numbers 4 and 5 mammary glands. The Lrp5-/- mouse strain described in this study has been further described in Lindvall C, Evans NC, Zylstra CR, Li Y, Alexander CM, Williams BO. 2006. The Wnt signaling receptor Lrp5 is required for mammary ductal stem cell activity and Wnt1-induced tumorigenesis. more...

(Submitter supplied) Dysregulation of Wnt/TCF signaling is closely associated with cancers arising from the gastrointestinal tract, inlcluding colon cancer and liver cancer. The goal of this study is to understand the transcriptional programs underlying Wnt/TCF activation in gastrointestinal cancers. We examined the transcriptional responses to TCF inhibition in cultured human colon cancer cells and liver cancer cells that are characteristic of Wnt pathway activation.

(Submitter supplied) Background: Basal cells (BC) are the stem/progenitor cells of the human airway epithelium capable of differentiating into secretory and ciliated cells. Notch signaling activation increases BC differentiation into secretory cells, but the role of individual Notch ligands in regulating this process is unknown Results: The objective of this study was to define the role of the Notch ligand JAG1 in regulating BC differentiation. more...

(Submitter supplied) The basal cell lineage in the mouse mammary gland is perceived to be composed mostly of differentiated myoepithelial cells intermixed with a rare subpopulation of mammary stem cells. Here, we show that a high proportion (~30%) of basal cells have colony forming capacity when actin-myosin contraction is prevented. A basal cell subpopulation enriched for mammary repopulating units (MRUs) is shown to be enriched for dividing cells. more...

(Submitter supplied) To delineate epithelial subpopulations in mouse mammary tissue, hematopoietic and endothelial cells were depleted from freshly isolated cell suspensions derived from mammary glands using fluorescence-activated cell sorting. The resultant Lin- population was fractionated into four distinct subpopulations using antibodies against CD29, CD24 and CD61. Based on the immunohistochemical phenotype, and in vivo and in vitro functional assays, these subpopulations were identified as fibroblast-containing stromal (CD29loCD24-), mammary stem cell (MaSC)-enriched (CD29hiCD24+CD61+), luminal progenitor (CD29loCD24+CD61+), and mature luminal (CD29loCD24+CD61-) cell subpopulations. more...

(Submitter supplied) Early full-term pregnancy affords lifetime protection against development of breast cancer. Parity-induced protection can be reproduced in a carcinogen-induced rat mammary carcinoma model. The molecular mechanisms of parity-induced protection against carcinogenic stimuli in rat mammary glands have not been fully characterized. In order to gain a better understanding of these molecular mechanisms, we performed gene expression analyses in parous and age-matched virgin (AMV) mammary glands of Lewis rats before and after carcinogen (N-methyl-N-nitrosourea; MNU) treatment. more...
