Abstract

The tricarboxylic acid (TCA) cycle enzyme succinate dehydrogenase (SDH) is a tumor suppressor. Heterozygosity for defective SDH subunit genes predisposes to familial paraganglioma (PGL) or pheochromocytoma (PHEO). Models invoking reactive oxygen species (ROS) or succinate accumulation have been proposed to explain the link between TCA cycle dysfunction and oncogenesis. Here we study the biochemical consequences of a common familial PGL-linked mutation, loss of the SDHB subunit, in a yeast model. This strain has increased ROS production but no evidence of mutagenic DNA damage. Because the strain lacks SDH activity, succinate accumulates dramatically and inhibits alpha-ketoglutarate (alphaKG)-dependent enzyme Jlp1, involved in sulfur metabolism, and alphaKG-dependent histone demethylase Jhd1. We show that mammalian JmjC-domain histone demethylases are also vulnerable to succinate inhibition in vitro and in cultured cells. Our results suggest that any alphaKG-dependent enzyme is a potential target of accumulated succinate in oncogenesis. The possible role that inhibition of these enzymes by succinate may have in oncogenesis is discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
