View SamplesThe transcription factor GATA3 is essential for luminal cell differentiation during mammary gland development and critical for formation of the luminal subtypes of breast cancer. Ectopic expression of GATA3 promoted global alterations of the transcriptome of basal triple-negative breast cancer cells resulting in molecular and cellular changes associated with a more differentiated, luminal tumor subtype and a concomitant reduction in primary tumor growth, lung metastasis, and macrophage recruitment at the metastatic site. Importantly, we demonstrate that the inhibition of metastases by GATA3 results from the suppression of lysyl oxidase (LOX) expression, a metastasis promoting matrix protein that affects cell proliferation, cross-linking of extracellular collagen types, and establishment of the metastatic niche.

View SamplesTGF-betas have complex roles in tumorigenesis, with context-dependent effects that can either suppress or promote tumor progression. Our goal was to use integrated genomic approaches in a model of human breast cancer progression to identify core TGF-beta-regulated genes that specifically reflect the tumor suppressor activity of TGF-beta. The model consisted of the non-tumorigenic MCF10A (M1), the premalignant MCF10AT1k.cl2 (M2), the early malignant MCF10Ca1h (M3) and the highly malignant, metastatic MCF10Ca1a.cl1 (M4) cell lines. We have previously shown that tumor suppressor activity of TGF-beta is lost in the highly malignant M4 cells.

View SamplesTGF-betas have complex roles in tumorigenesis, with context-dependent effects that can either suppress or promote tumor progression. We have previously shown that TGF-beta has tumor suppressor activity in the MCF10Ca1h (M3) human breast cancer xenograft model. To identify potential molecular players in the tumor suppressor responses, we performed global gene expression analyses.

View SamplesUsing a syngeneic p53 null mouse mammary gland tumor model that closely mimics human breast cancer, we have identified by limiting dilution transplantation as well as in vitro mammosphere and clonogenic assays a Lin-CD29HighCD24High subpopulation of tumor-initiating cells. Differentially expressed genes in the Lin-CD29HighCD24High mouse mammary gland tumor-initiating cell population include those involved in DNA damage response and repair, as well as genes involved in epigenetic regulation previously shown to be critical for stem cell self-renewal.
