Gene expression profiling of Wwox targeted ablation in mouse mammary epithelial cells

ABSTRACT: The WWOX gene has been implicated in human cancers, including breast cancer.The development and tumorigenesis between human and mouse mammary glands (MGs) share similar molecular details and signal transduction pathways. We established mouse line that specifically knockout the expression of WWOX gene in the MG epithelial cells (MECs) by crossing BK5-cre mice with our WWOX flox stain. In order to study the gene expression profile in the subpopulation MECs, we isolated the organoids from the 4th MGs of both BK5-cre +; WWOX flox/flox (KO) mice and their WT counterparts (BK5-cre -; WWOX flox/flox), 3 mice each genotype. The total RNA from the mouse MG organoids was extracted and purified by TRIzol/RNeasy Kit and their integrity was checked on Agilent RNA 6000 Nanochip. The goal is to identify the significant perturbation in tumorigenic pathways in these cells induced by WWOX ablation. Mammary gland epithelial organoids samples and gene expression profiles were deribed from three WWOX-KO mice (BK5-cre +; WWOX flox/flox) and from three WWOX-WT mice (BK5-cre -; WWOX flox/flox)

Expression data from sorted control and Pygo2-null mouse mammary stem/basal cells

Project description: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 To gain the insight into gene expression profiles in control and Pygo2 SSKO mammary epithelial cells (MECs), we sorted the freshly isolated mouse MECs into MaSC/basal (Lin-CD29hiCD24+) and mature luminal population (Lin-CD29lowCD24+CD61-), and extract total RNA for cDNA microarray analysis

Expression profiling on lactation day 2 mammary epithelial cells from constitutive miR-150 expressing mice compared to controls.

Project description:Constitutive expression of miR-150 in mammary epithelium causes severe lactation defects. Mammary epithelial cells (MECs) at lactation day 2 were isolated from four homozygous ROSA26-lox-STOP-lox-miR-150 (Stop-150) mice with WAP-driven Cre (WAP-Cre) and compared to MECs from four WAP-Cre control mice. Statistical analysis of the mRNA changes between the two genotypes identified supression of many lipid and cholesterol synthesis genes due to constitutive expression of miR-150.

Targeted ErbB3 loss in mammary organoids harvested from ErbB3 DOX-KO mice +/- DOX treatment

Project description:Mammary organoids harvested from ErbB3 DOX-KO mice, which utilize MMTV-Cre transgene expression in the LE to cause genomic recombination at floxed ErbB3 alleles in ErbB3FL/FL were cultured in the presence or absence of doxycycline to induce ErbB3 loss. The gene expression shift following DOX-induced ErbB3 loss in the 3D organoids was examined by microarray. Gene expression patterns were interrogated in mammary organoids from ErbB3 inducible-knockout mice cultured in the presence of absence of doxycycline. Three biological replicates of the experiment were performed, resulting in a total of 6 samples (3 treatment, 3 control).

RNAseq of mouse mammary luminal cells

Project description:The mammary epithelia are mainly composed of two distinct lineages, the basal and luminal cells. In our MMTV-Cre; Brca1flox/flox mouse model, we found the Brca1 knockout mainly occurred in the luminal cells, which will lead the mammary tumorigenesis. To investigate the Brca1 deficiency mediated mammary tumorigenesis, we sorted the luminal cells from wild type mice and MMTV-Cre; Brca1flox/flox mice for RNAseq analysis.

Single cell RNA-Seq data for Trp53/Brca1-null premalignant mammary epithelial cells and tumor cells with a K8+ luminal origin

Project description:BRCA1 mutation-carriers are predisposed to develop Basal-like breast cancer (BLBC), and p53 mutations are present in the majority of human BLBC cases, suggesting loss of these two tumor suppressors play key roles in development of BLBC. Recent studies suggest that the majority of human breast cancers, including BLBC, may originate from mammary epithelial cells (MECs) in the luminal lineage. However, how loss of p53 and BRCA1 contributes to development of BLBC from luminal MECs remains largely elusive. We developed a novel genetic targeting and lineage tracing approach based on intraductal injection of Cre-expressing adenovirus under the control of the pan-luminal Keratin 8 (K8) promoter (Ad-K8-Cre). We performed intraductal injection of Ad-K8-Cre to female mice carrying conditional knockout alleles of Brca1 (Brca1L) and Trp53 (Trp53L). The injected females developed mammary tumors similar to human BLBC within 12 months after injection. Here we characterized MECs targeted by Ad-K8-Cre at different time points after the intraductal injection, as well as mammary tumors developed in this model, by single cell expression analysis.

Impact of IRP deficiency on the proteome of Ly6G+ cells from the bone marrow in mice

Project description:The overall objective of the project is to evaluate the effects of loss of function of iron regulatory proteins (IRP1, encoded by Aco1)-1 and -2 (IRP2, encoded by Ireb2) during adult life. Mice carrying floxed Aco1 and Ireb2 alleles were crossed to a knockin strain expressing a tamoxifen-inducible CRE recombinase under the control of the Rosa26 promoter. The resulting Aco1flox/flox,Ireb2flox/flox,Rosa26+/CreERT2 mice are designated P1/2-KO; littermates lacking the CreER sequence (Aco1flox/flox,Ireb2flox/flox,Rosa26+/+) serve as reference and are designated P1/2-CTR. Adult mice were injected (i.p.) with tamoxifen on day 1 and day 3 to ablate the IRPs in the whole body, and were sacrificed on day 10 for analysis. Bone marrow cells were collected and LY6G+ cells were magnetically sorted for proteome analysis by LC-MS/MS using an Ultimate 3000 UPLC system connected to an Orbitrap Exploris 480 mass spectrometer.
