Increased succinate or fumarate levels as a consequence of SDH and FH deficiency inhibit hypoxia inducible factor-1alpha (HIF-1alpha) prolyl hydroxylases leading to sustained HIF-1alpha expression in tumours.

As expected, hypoxia-inducible factor-1 alpha (HIF-1 alpha) and HIF-2alpha were up-regulated in chronically silenced cells, suggesting that a pseudohypoxic state was attained.

In the FH and SDH deficient tumors, accumulation of the substrates, fumarate and succinate, has been shown to cause stabilization of hypoxia inducible factor 1 alpha (HIF1 alpha).

Up-regulation of the hypoxia markers hypoxia inducible factor 1 (HIF-1alpha) and pyruvate dehydrogenase kinase 1 (PDK1) was also observed, suggesting that in vivo adaptation to hypoxia requires an active metabolic switch.

PURPOSE: To examine insulin-like growth factor (IGF)-1 stimulation of expression of hypoxia inducible factor (HIF)-1 alpha and secretion of vascular endothelial growth factor (VEGF) and IGF binding protein (IGFBP)-3 in human retinal pigment epithelial (RPE) cell line D407.

Parenthetically, hypoxia markers such as hypoxia inducible factor 1 alpha (HIF-1alpha) and pyruvate dehydrogenase kinase 1 (PDK1) were still at the pre-hypoxia levels, whereas the mammalian target of rapamycin (mTOR), a marker of protein synthesis, was reduced.
