Germline mutations in nuclear genes encoding mitochondrial enzymes fumarate hydratase (FH) and succinate dehydrogenase (subunits SDHB/C/D) have been implicated in the development of tumor syndromes referred to as hereditary leiomyomatosis and renal cell cancer (HLRCC) and hereditary paragangliomatosis (HPGL), respectively.

Enzyme depletion and mutations in SDHA compromise TCA activity and energy production, whereas mutations in SDHB, SDHC, and SDHD induce paraganglioma.

Since HIF-1alpha is frequently expressed in breast carcinomas, DNA methylation at the promoter regions of the SDHA, SDHB, SDHC and SDHD and FH genes was evaluated as a possible mechanism in silencing of SDH and FH expression in breast carcinomas.

Mutations in the genes encoding the three other succinate dehydrogenase subunits (SDHB, SDHC and SDHD) have been identified in patients affected by familial or 'apparently sporadic' paraganglioma and/or pheochromocytoma, an autosomal inherited cancer-susceptibility syndrome.

Here we study the biochemical consequences of a common familial PGL-linked mutation, loss of the SDHB subunit, in a yeast model.

J Clin Invest. 2006 Jan;116(1):125-36. Epub 2005 Dec 22.


Mechanistically, RIP140 was found to require the nuclear receptor ERRalpha to regulate hexose uptake and mitochondrial proteins SDHB and CoxVb, although it likely acts through other nuclear receptors as well.

When cultured in YPD medium containing 15% glucose under aerobic conditions, the KGD1 (alpha-ketoglutarate dehydrogenase) gene disrupted mutant produced a lower level of succinate than the wild-type strain, while the SDH1 (succinate dehydrogenase) gene-disrupted mutant produced an increased level of succinate.
