SpletClinical symptoms can be traced back to disruption of the malate-aspartate shuttle due to the lack of citrin. A potential therapy for this condition is the expression of aralar, the AGC present in brain, to replace citrin. To explore this possibility we have first verified that the NADH/NAD+ ratio increases in hepatocytes from citrin(−/− ...

This shuttle for transporting reducing equivalents from cytosolic NADH into the mitochondrial matrix … 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 aim of the present study was to investigate enzyme levels of the malate-aspartate and alpha-glycerophosphate shuttles in type I (slow-twitch) and type II (fast-twitch) fibres of human skeletal muscle.

SpletAbstract Citrin, encoded by SLC25A13, is a component of the malate-aspartate shuttle, which is the main NADH-transporting system in the liver. Citrin deficiency causes neonatal intrahepatic cholestasis (NICCD), which usually resolves within the first year of life. brick interior wall costSplet15. maj 2024 · The malate aspartate shuttle (MAS). Cytosolic malate dehydrogenase (MDH1) transfers the reducing equivalents from NADH to oxaloacetate (OAA). This reaction generates malate (Mal) and replenishes cytosolic NAD +.
