Splet21. sep. 2008 · The malate–aspartate (M–A) shuttle provides an important mechanism to regulate glycolysis and lactate metabolism in the heart by transferring reducing … SpletThis pathway is known as the malate-aspartate shuttle, because it involves exchange of mitochondrial aspartate for cytosolic malate: aspartate from the mitochondria crosses to the cytosol. aspartate is transaminated (at the expense of ketoglutarate) to yield oxaloacetate oxaloacetate is reduced to malate by cytosolic NADH
Spletthe malate–aspartate shuttle has been debatable until the transporters required for the malate–aspartate shuttle to operate were identified (Palmieri et al. 1996, 1999, 2001; Cavero et al. 2003). Here our data showed that the malate–aspartate shuttle played a major role in mediating life span extension under CR as well as in Figure 6. SpletThe resulting lack of cytoplasmic ATP and NADH produced in the hippocampus are likely to be compensated by blood lactate influx that can provide NADH to be oxidized by the …
SpletThe mdh1Δaat1Δ double mutation blocks CR-mediated life span extension and also prevents the characteristic decrease in the NADH levels in the cytosolic/nuclear pool, suggesting that the malate–aspartate shuttle plays a major role in the activation of the downstream targets of CR such as Sir2. Overexpression of the NADH shuttles may also ... Splet15. maj 2024 · Abstract. Over the last few years, various inborn disorders have been reported in the malate aspartate shuttle (MAS).

SpletPred 1 dnevom · One such cycle is the malate-aspartate shuttle (MAS), which uses malate as intermediate electron carrier to transport the electrons from cytosolic NADH to mitochondrial NADH [8]. The other cycle is the glycerol-phosphate shuttle (GPS), which uses Glycerol-3-phosphate as intermediate to transport the electrons over the membrane to …
