Lack of complex I is associated with oncocytic thyroid tumours

Br J Cancer. 2009 May 5;100(9):1434-7. doi: 10.1038/sj.bjc.6605028. Epub 2009 Apr 7.

Abstract

Oncocytic tumours are characterised by hyperproliferation of mitochondria. We immunohistochemically analysed all enzymes of the oxidative phosphorylation system in 19 oncocytic thyroid tumours. A specific lack of complex I was detected, which was expressed at <5% of the level determined in surrounding non-cancerous tissue.
