The Lipogenic Phenotype Of Her2/Neu-Positive Breast Cancer Cells, Jan Martin Baumann
Legacy Theses & Dissertations (2009 - 2024)
Recent work has shown that HER2/neu-positive breast cancer cells rely on a unique Warburg-like metabolism for survival and aggressive behavior. These cells are dependent on fatty acid (FA) synthesis, show markedly increased levels of stored fats and disruption of the synthetic process results in apoptosis. Supplementation of the growth media with physiological concentrations of saturated FAs induces cell death, whereas HER2-normal cells are not affected. This is particularly interesting in the context of new epidemiological data showing that a diet rich in saturated FAs is positively correlated with the development of HER2-negative disease, but not HER2/neu-positive disease.
