pancreatic cancer

A metabolic hypothesis of cell growth and death in pancreatic cancer

INTRODUCTION: Tumor cells, just as other living cells, possess the potential for proliferation, differentiation, cell cycle arrest, and apoptosis. There is a specific metabolic phenotype associated with each of these conditions, characterized by the production of both energy and special substrates necessary for the cells to function in that particular state. Unlike that of normal living cells, the metabolic phenotype of tumor cells supports the proliferative state.

Wheat germ extract decreases glucose uptake and RNA ribose formation but increases fatty acid synthesis in MIA pancreatic adenocarcinoma cells

The fermented wheat germ extract with standardized benzoquinone composition has potent tumor propagation inhibitory properties. The authors show that this extract induces profound metabolic changes in cultured MIA pancreatic adenocarcinoma cells when the [1,2-13C2]glucose isotope is used as the single tracer with biologic gas chromatography-mass spectrometry. MIA cells treated with 0.1, 1, and 10 mg/mL wheat germ extract showed a dose-dependent decrease in cell glucose consumption, uptake of isotope into ribosomal RNA (2.4%, 9.4%, and 28.0%), and release of 13CO2.
