Fields of Interest

Effect of dietary restriction on the growth of brain tumors.

Academic Profile

I am seeking to define the molecular effects of total dietary restriction on brain tumor growth. Dietary restriction has documented beneficial effects on numerous diseases including cancer, yet its mechanism of action is unknown. Recently, we showed that dietary restriction has significant pro-apoptotic and anti-angiogenic effects on the inhibition of experimental brain tumor growth. Dietary restriction induced increase in apoptosis is associated with caspase-3 activation and PARP cleavage in brain tumors. Insulin like growth factor–1 (IGF-1) is a peripheral anti-apoptotic molecule, and is known to be influenced by dietary restriction. Therefore, we are interested to see whether or not dietary restriction influences ceramide levels and ceramide-linked regulatory proteins of apoptosis in brain tumors (i.e., if the IGF-1-ceramide-Fas-caspase signaling axis is the pathway influenced by dietary restriction).

My other project deals with anti-angiogenic effect of dietary restriction on brain tumors. We observed that dietary restriction significantly reduces micro-vessel density in tumors along with the reduction of serum vascular endothelial growth factor (VEGF), a major angiogenic cytokine. I am now focusing on the effects of dietary restriction on macrophage infiltration (TIMs) and angiogenic cytokine production in brain tumors. Recently, it was reported that IL-8 is induced in human glioma cells upon l igation of Fas. Therefore, Fas is not only an inducer of apoptosis, but also a mediator of angiogenesis in human brain tumors. Tumor cells may be protected from Fas-mediated apoptosis by the opposing angiogenic activity of IL-8 induced by Fas ligation. Macrophage inflammmatory protein (MIP-2), human homologue to IL-8, is one of the cytokines governed by Fas/CD95 pathway in gliomas and also influenced by caspases. Therefore, it will be interesting to see whether or not caloric stress can reduce the level of MIP-2.
