18291703 Dlaskova A, Hlavata L, Jezek P: Oxidative stress caused by blocking of mitochondrial complex I H (+) pumping as a link in aging/disease vicious cycle. Int J Biochem Cell Biol. 2008;40(9):1792-805. Epub 2008 Jan 19.

Rotenone caused a 5-fold J (m) increase (AC (50) 2 microM), which was attenuated by uncoupling, membrane potential (DeltaPsi (m)), and DeltapH-collapse, since addition of FCCP (IC (50) 55 nM), valinomycin, and nigericin prevented this increase.
A hydrophobic amiloride that acts on the ND5 subunit and inhibits Complex I H (+) pumping enhanced J (m) and even countered the FCCP effect (AC (50) 0.3 microM).

The mitochondrial rotenone-sensitive NADH:ubiquinone oxidoreductase (complex I) comprises more than 35 subunits, the majority of which are encoded by the nucleus.
In Chlamydomonas reinhardtii, only five components (ND1, ND2, ND4, ND5 and ND6) are coded for by the mitochondrial genome.

We found that [3H] BPA was photo-crosslinked to ND2, ND1 and ND5 subunits, by the three dimensional separation (blue-native/doubled SDS-PAGE) of [3H] BPA-treated bovine heart submitochondrial particles.
The cross-linking was blocked by rotenone.

The line shapes of the EPR spectra of the Fe-S clusters are slightly broadened relative to spectra measured on complex I purified by conventional means, and the quinone reductase activity is insensitive to rotenone.
The sequences of many of them contain hydrophobic segments that could be membrane spanning, including at least two mitochondrial gene products, ND4 and ND5.

Subsequently, we isolated several mutants affected in one or another of the mtDNA-encoded subunits of complex I by exposing established cell lines to high concentrations of rotenone.
In fact, the synthesis of the ND5 polypeptide is rate limiting for the activity of the enzyme.

In the course of analysis of eight mutants of the human cell line VA2B selected for their resistance to high concentrations of the complex I inhibitor rotenone, seven were found to be respiration deficient, and among these, six exhibited a specific defect of complex I.
A detailed molecular analysis of the six complex I-deficient mutants revealed that two of them exhibited a frameshift mutation in the ND4 gene, in homoplasmic or in heteroplasmic form, resulting in the complete or partial loss, respectively, of the ND4 subunit; two other mutants exhibited a frameshift mutation in the ND5 gene, in near-homoplasmic or heteroplasmic form, resulting in the ND5 subunit being undetectable or strongly decreased, respectively.
