(Submitter supplied) Stem cell antigen-1 (Sca-1 or Ly6A) is a member of the Ly6 family of glycosyl phostidylinositol (GPI)-anchored cell surface proteins. To determine the potential mechanisms by which Sca-1 regulates cell migration, adhesion, and tumor development; we performed an Affymetrix mouse genome 430A 2.0 array on cDNA comparing shLuc and shSca-1 from cells grown in vitro.

(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) Pea3 and Erm are transcription factors belonging to the ETS family which are involved in tumorigenesis, particularly mammary oncogenesis. To elucidate the mechanism of Pea3/Erm induced tumorigenesis in mouse mammary cancerous MMT cells (ATCC CCL-51), we have down-regulated Pea3 or Erm expression in this cell line by using small interfering RNA and performed a microarray analysis using Applied Biosystems AB1700 technology to define target associated genes. more...

Gene expression profile in the following four groups of cells were compared: non-PA Sca-1-, non-PA Sca-1+, 72 h post-PA Sca-1- and 72 h post-PA Sca-1+.

(Submitter supplied) The differentiation of stem-like cells of tumors may contribute to the cellular heterogeneity of breast cancers. We report the propagation of highly enriched mouse mammary cancer stem cells that retain the potential to differentiate both in vivo and in culture and their use to identify chemical compounds that influence both self-renewal and differentiation. We identify epithelial tumor initiating cells (ETIC) that expresses lineage markers of both basal and luminal mammary cell lineages and retains the potential to generate heterogeneous tumors similar to the tumor of origin from even single cells. more...

(Submitter supplied) Study designed to obtain microRNA profile of tumorigenic Sca-1+CD34+ cells during the formation of pulmonary adenocarcinoma. After intranasal infection with adenovirus CRE (Ad-Cre), lung adenocarcinoma was identified pathologically in Lox-stop-lox Kras (LSL-Kras) G12D mice. Sca-1+CD34+ cells were sorted by flow cytometry and tested for the tumor-initiating ability to undergo self-renewal and differentiation. more...

(Submitter supplied) The Wnt gene family is an evolutionarily conserved group of proteins that regulate cell growth, differentiation, and stem cell self-renewal. Aberrant Wnt signaling in human breast tumors has been proposed to be an attractive drug target, especially in the basal-like subtype where canonical Wnt signaling is both enriched and predictive of poor clinical outcomes. The development of effective Wnt based therapeutics, however, has been slowed in part by a limited understanding of the context dependent nature with which these aberrations influence breast tumorigenesis. more...

(Submitter supplied) MicroRNAs (miRNAs) are small, non-coding, endogenous RNAs involved in many human diseases including breast cancer. miRNA expression profiling of human breast cancers has identified miRNAs related to the clinical diversity of the disease and potentially provides novel diagnostic and prognostic tools for breast cancer therapy. In order to further understand the roles of miRNAs in association with oncogenic drivers and in specifying sub-types of breast cancer, we performed miRNAexpression profiling on mammary tumors from eight well-characterized genetically -engineered Mouse (GEM) models of human breast cancer including MMTV–H-Ras, -Her2/neu, -c-Myc, -PymT, –Wnt1 and C3(1)/SV40 T/t-antigen transgenic mice, BRCA1fl/fl;p53+/-;MMTV-cre and the p53fl/fl ;MMTV-cre transplant model.

The gene expression data will be combined with the miRNA gene expression data from the corresponding mammary tumors and tissues for integrated miRNA and mRNA gene expression analysis, which are useful in improving the identification of miRNA targets from potential targets identified in silico.

(Submitter supplied) Spontaneous mammary tumours are the most prevalent type of neoplasm in women as well as in female dogs. Even though ovarian hormones, mainly estrogens and progestins, are known to play a key role in mammary tumorigenesis, conflicting reports have been obtained from in vivo and in vitro studies concerning their role, especially of progestins, in mammary tumorigenesis. Prolonged exposure to high levels of progestins during unusually long luteal phase of oestrous cycle is suspected to be the key event in canine mammary tumorigenesis. more...

The molecular background behind this difference in behavior needs to be studied to elucidate how adult progenitor cells can restore cardiac function of the damaged myocardium. Since the brain-derived neurotrophic factor (BDNF) moderates cardioprotection in injured hearts, we focused on delineating its regulatory role in the damaged myocardium. more...
