We evaluated electron transport chain activity in platelet mitochondria taken from HD patients. All 5 patients studied had striking depressions of NADH:ubiquinone oxidoreductase activity (complex I) (5.36 +/- 2.91 nmol/min/mg; control mean, 19.12 +/- 5.64 nmol/min/mg). Other electron transport chain activities were not significantly different from control values. HD may be caused by a mutation in 1 of the nuclear coded subunits of NADH:ubiquinone oxidoreductase.
我们评估了来自HD患者的血小板线粒体中的电子传递链活性。所有5名接受研究的患者的NADH:泛醌氧化还原酶活性(复合体I)均显著降低(5.36±2.91 nmol/分钟/毫克;对照组平均值为19.12±5.64 nmol/分钟/毫克)。其他电子传递链活性与对照值无显著差异。HD可能是由NADH:泛醌氧化还原酶的一个核编码亚基发生突变引起的。
