Journal ArticleDOI

A "Silent" Polymorphism in the MDR1 Gene Changes Substrate Specificity

TL;DR: It is hypothesized that the presence of a rare codon, marked by the synonymous polymorphism, affects the timing of cotranslational folding and insertion of P-gp into the membrane, thereby altering the structure of substrate and inhibitor interaction sites.
Journal ArticleDOI

Brca1 breast tumors contain distinct CD44+/CD24- and CD133+ cells with cancer stem cell characteristics

TL;DR: Brca1-deficient mouse mammary tumors harbor heterogeneous cancer stem cell populations, and CD44+/CD24- cells represent a population that correlates with human breast cancer stem cells.
Journal ArticleDOI

Redefining the relevance of established cancer cell lines to the study of mechanisms of clinical anti-cancer drug resistance

TL;DR: The necessity for new in vitro cancer models and the use of primary tumor models in which gene expression can be manipulated and small molecules tested in a setting that more closely mimics the in vivo cancer microenvironment is emphasized so as to avoid radical changes in gene expression profiles brought on by extended periods of cell culture.
Journal ArticleDOI

Prolonged Drug Selection of Breast Cancer Cells and Enrichment of Cancer Stem Cell Characteristics

TL;DR: The cell population with cancer stem cell characteristics increased after prolonged continuous selection for doxorubicin resistance, and MCF-7/ADR cells were highly invasive, formed mammospheres, and were tumorigenic in mice.
Journal ArticleDOI

Reversal of ABC drug transporter-mediated multidrug resistance in cancer cells: Evaluation of current strategies

TL;DR: This review summarizes the recent advances in identifying strategies to restore sensitivity to chemotherapeutics in multidrug resistant cancer cells.
