Import of lipids into mitochondria
Witrynaacids, lipids, iron–sulphur clusters and regulate apoptosis. About 99% of mitochondrial proteins are encoded by nuclear genes, so the biogenesis of mitochondria heavily depends on protein import pathways into the organelle. An intricate system of well-studied import machinery facilitates the import of mitochondrial proteins. Witryna3 maj 2024 · Figure 2.Mitochondrial dysfunction and insulin resistance. Impaired mitochondria oxidative capacity leads to a decrease in metabolic substrate catabolism resulting in increased intramyocellular fatty acids availability, which may be channelled towards lipotoxic lipid species biosynthesis (i.e., ceramide and diacylglycerol) both of …

Witrynadria requires the import not only of proteins from the cytoplasm but also of lipids from extramitochondrial membranes as mitochondria cannot synthesize all the lipids necessary for membrane biogenesis. While mecha-nisms of protein import into mitochondria are now well described [1], much less is known about processes WitrynaThe mitochondria play a crucial role in cellular metabolism, reactive oxygen species (ROS) production, and apoptosis. Aberrant mitochondria can cause severe damage to the cells, which have established a tight quality control for the mitochondria. This process avoids the accumulation of damaged mitochondria and can lead to the …
