Ancient Homology of the Mitochondrial Contact Site and Cristae Organizing System Points to an Endosymbiotic Origin of Mitochondrial Cristae
Mitochondria are eukaryotic organelles that originated from an endosymbiotic α-proteobacterium. As an adaptation to maximize ATP production through oxidative phosphorylation, mitochondria contain inner membrane invaginations called cristae. Recent work has characterized a multi-protein complex in yeast and animal mitochondria called MICOS (mitochondrial contact site and cristae organizing syste...
متن کاملUnusual Mitochondrial Cristae in the Vinegar Eelworm
MATERIALS AND METHODS Stock cultures of T. aceti were grown axenically at 27 °C in a liquid medium described by Castillo and Krusberg (2) . Female nematodes from two cultures were examined, one of which had been maintained at East Wareham for 4 yr and the other obtained from the Department of Cell Physiology, Boston Biomedical Research Institute . Age at sacrifice for electron microscopy was de...

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولOPA1 Controls Apoptotic Cristae Remodeling Independently from Mitochondrial Fusion
Mitochondria amplify activation of caspases during apoptosis by releasing cytochrome c and other cofactors. This is accompanied by fragmentation of the organelle and remodeling of the cristae. Here we provide evidence that Optic Atrophy 1 (OPA1), a profusion dynamin-related protein of the inner mitochondrial membrane mutated in dominant optic atrophy, protects from apoptosis by preventing cytoc...

Early in apoptosis, mitochon-drial cristae are remodeled so that cytochrome c enters the space between the inner and outer mito-chondrial ...
