Example sentences for: mevalonate
How can you use “mevalonate” in a sentence? Here are some example sentences to help you improve your vocabulary:
It has been speculated that an abnormality of translocation of 3-MGC acid across the mitochondrial membrane may be the source of 3-MGC aciduria in these patients [ 23 ] . The link between 3-MGC aciduria and mitochondrial dysfunction may involve failure of mitochondrial uptake of 3-MGC acid or potentially defective ubiquinone biosynthesis leading to increased levels of mevalonate in the mevalonate shunt pathway with subsequent increased synthesis of 3-MGC acid [ 27 ] .
In further support of a role for isoprenoids, we were able to demonstrate that supplementation of cells with mevalonate abolished statin-activated shedding (see Figure 4).
Instead, the pattern that we observed raises the possibility that statins, presumably via isoprenoids (given the reversibility with mevalonate), as discussed in the next section, may alter sorting of cellular holoAPP, diverting holoproteins away from terminal degradation in the endosomal/lysosomal pathway and into the constitutive secretory pathway that generates sAPP α . However, the fold effect on reduced intracellular turnover in the endosomal/lysosomal pathway (or sorting out of the endosomal/lysosomal pathway and into the constitutive secretory/shedding pathway) is apparently insufficient to explain the fold effect on sAPP α generation (2-fold for the former, vs 3- to 4-fold for the latter), indicating a contribution from a downstream site in the processing pathway.
Since FTI-1 acts downstream of HMGCoA reductase, the stimulatory effect of FTI-1 on sAPP α shedding would not be predicted to be modified by mevalonate supplementation.
Therefore, the addition of mevalonate would be predicted to antagonize statin action via the isoprenoid pathway, by relieving statin-induced mevalonate deficiency.
