Research Interests

Our major focus over the last five years has been to understand the role of the hexose transporter Glut1 in mammary tumorigenesis.  We recently published that loss of Glut1 was sufficient to prevent mammary tumorigenesis induced by activated ErbB2.  Most surprising was the observation was that loss of a single allele of Glut 1 was sufficient to block tumorigenesis; in other words, Glut1 was haplo-insufficient for tumorigenesis.  This implies there is a threshold of glucose that is required for tumorigenesis, and a reduction in glucose uptake may be sufficient to block or prevent tumorigenesis.  Using an in vitro model of ErbB2-dependent transformation of mammary epithelial cells, we showed that limiting glucose concentration to physiological levels prevented transformation of cells in three-dimensional cultures.  

One logical conclusion of these studies is that tumor-initiating cells, or cancer stem cells, that lack Glut1 are not able to proliferate and undergo apoptosis.  To address this hypothesis, we have labelled tumor-initiating cells that express ErbB2 and Cre recombinase (both are co-expressed by the NIC transgene) by introducing a transgene in which expression of green fluorescent protein is prevented by the presence of a lox-stop-lox cassette (LSL); as a result of this second transgene all Cre-expressing tumor cells are GFP+. Using fluorescent-activated cell sorting with established cell surface markers (CD24 and CD29), we have been able to isolate populations of GFP-expressing cells that correspond to mature luminal cells, luminal progenitors, and basal progenitors.  The identity of these different subpopulations was confirmed by RNA-Seq analysis.  Both the luminal and basal progenitor cells that express activated ErbB2 are able to form tumors upon transplantation into immunodeficient mice.  ErbB2 expressing basal and luminal progenitor cells that were GFP+ could be isolated from mammary glands of MMTV-NIC mice that contain one copy, or no copies of Glut1, implying that the tumor initiating cells (caner stem cells) are not lost from these mice.  We are currently analyzing RNA –Seq data to determine the differences in gene profiles between cancer stem cells that vary in expression of Glut1.  These studies should reveal how glucose metabolism alters gene expression and the biology of tumor cells.

Since diabetes and obesity promote breast cancer in humans, we wish to use our mouse models to determine the extent to which these conditions alter tumorigenesis in mice.  In collaboration with Dr. Wellberg, who has developed a new model for diet-induced obesity and hyperglycemia, we want to determine whether hyperglycemia will promote tumorigenesis in mice lacking one allele of Glut1.  Given that two-thirds of women are now overweight or obese, understanding how these conditions alters mammary tumorigenesis in mice addresses a significant health problem in the developed world.
