Fatty acids are broken down in the mitochondria by catabolic process (beta oxidation) to gen- erate two-carbon units (Acetyl-CoA), which can be oxidized to CO2 and H2O via the TCA cycle or used to generate hexose via the glyoxylate and gluconeogenesis, and NADH and FADH2, which are co-...
Recent evidence indicates that mitochondria lie at the heart of immunity. Mitochondrial DNA acts as a danger-associated molecular pattern (DAMP), and the mitochondrial outer membrane is a platform for signaling molecules such as MAVS in RIG-I signaling, and for the NLRP3 inflammasome. Mitochondrial...
Dietary mono-unsaturated fatty acids (MUFAs) are linked to longevity in several species. But the mechanisms by which MUFAs extend lifespan remain unclear. Here we show that an organelle network involving lipid droplets and peroxisomes is critical for MUFA-induced longevity in Caenorhabditis elegans. ...

indicating antioxidant action. In the mitochondria, astaxanthin reduces free radical generation. However, siRNA knockdown of Nrf2 prevents the effect of astaxanthin on HO-1 activity [181]. Later, neuroblastoma cells were stressed with H2O2, causing redox impairment and mitochondrial malfunction. Pretreatme...
They are vesicular or branched structures formed by invaginated of the plasma membrane. They represent the eukaryotic mitochondria in function and are the site of action of the bacterial respiration enzymes. 2.3 Inclusion bodies They are believed to be storage food. They are of two types; (i)...
Accordingly, DGAT1 inhibition led to an increase in lipid peroxidation from 24 h, with further increases by 48 h both in the cytoplasm (Figure 5D) and in the mitochondria specifically (Figure 5E). Additionally, depletion of DGAT1 resulted in increased protein conjugation with 4-hydroxynonenal (...
Liver fat storage, also called hepatic steatosis, is increasingly common and represents a very frequent diagnosis in the medical field. Excess fat is not without consequences. In fact, hepatic steatosis contributes to the progression toward liver fibrosi
Hence, we still know little on the effects of stress and the GC response on oxidative stress in the wild. In particular, whether species that evolved in stochastic and challenging environments may present adaptations to cope with stress-induced oxidative stress is unknown. Since mitochondria are ...

Due to these proteins produced here in mitochondria being respiratory ...
