Journal ArticleDOI
A sensitive assay for dNTPs based on long synthetic oligonucleotides, EvaGreen dye and inhibitor-resistant high-fidelity DNA polymerase.
TL;DR: A simple non-radioactive microplate assay for the quantification of dNTPs with a minimum requirement of 4–12 mg of biopsy material based on long synthetic single-stranded DNA templates, an inhibitor-resistant high-fidelity DNA polymerase, and the double-strander-DNA-binding EvaGreen dye that quantified reliably and discriminated well against ribonucleotides.
Journal ArticleDOI
Alternative oxidase-mediated respiration prevents lethal mitochondrial cardiomyopathy
Jayasimman Rajendran,Janne Purhonen,Saara Tegelberg,Saara Tegelberg,Olli-Pekka Smolander,Matthias Mörgelin,Jan Rozman,Valerie Gailus-Durner,Helmut Fuchs,Martin Hrabé de Angelis,Petri Auvinen,Eero Mervaala,Howard T.

TL;DR: The value of AOX is demonstrated, both as a mechanistic tool and a potential therapeutic strategy, for cIII deficiencies, showing that the restored electron flow upstream of cIII was sufficient to prevent cardiac energetic crisis and detrimental decompensation.
Journal ArticleDOI
Ketogenic diet attenuates hepatopathy in mouse model of respiratory chain complex III deficiency caused by a Bcs1l mutation
Janne Purhonen,Jayasimman Rajendran,Matthias Mörgelin,Kristiina Uusi-Rauva,Shintaro Katayama,Kaarel Krjutškov,Elisabet Einarsdottir,Elisabet Einarsdottir,Vidya Velagapudi,Juha Kere,Matti Jauhiainen,Vineta Fellman,Vineta Fellman,Jukka Kallijärvi +13 more
TL;DR: A striking beneficial hepatic response to KD is revealed in mice with mitochondrial hepatopathy and warrant further investigations of dietary modification in the management of these conditions in patients.
Journal ArticleDOI
The mitochondrial coenzyme Q junction and complex III: biochemistry and pathophysiology.
TL;DR: The role of the CoQ-linked metabolism in the pathogenesis of human diseases of oxidative phosphorylation (OXPHOS) is discussed in this paper, in which the coq homeostasis is directly or indirectly affected.
Journal ArticleDOI
Respiratory chain complex III deficiency due to mutated BCS1L: a novel phenotype with encephalomyopathy, partially phenocopied in a Bcs1l mutant mouse model.
Saara Tegelberg,Nikica Tomašić,Nikica Tomašić,Jukka Kallijärvi,Janne Purhonen,Eskil Elmér,Eva Lindberg,David Gisselsson Nord,Maria Soller,Nicole Lesko,Nicole Lesko,Anna Wedell,Anna Wedell,Helene Bruhn,Helene Bruhn,Christoph Freyer,Christoph Freyer,Christoph Freyer,Henrik Stranneheim,Henrik Stranneheim,Rolf Wibom,Rolf Wibom,Inger Nennesmo,Anna Wredenberg,Anna Wredenberg,Anna Wredenberg,Erik A.

TL;DR: Novel manifestations in brain, skeletal muscle and liver, including abnormality in specialized resident macrophages (microglia and Kupffer cells) are shown, which forward the understanding of CIII deficiencies caused by BCS1L mutations.
