I have a '5 Way Reflector' that I want to use in my photography, which includes the following 5 options: 1  Gold reflective. 2  Silver reflective. 3  Gold/silver alternating pattern reflective. 4  White. 5  Scrim/opaque. 6  Black*.
The endoplasmic reticulum (ER) resident PKR-like kinase (PERK) is necessary for Akt activation in response to ER stress. We demonstrate that PERK harbors intrinsic lipid kinase, favoring diacylglycerol (DAG) as a substrate and generating phosphatidic acid (PA). This activity of PERK correlates with activation of mTOR and phosphorylation of Akt on Ser473. PERK lipid kinase activity is regulated in a phosphatidylinositol 3-kinase (PI3K) p85Î±-dependent manner. Moreover, PERK activity is essential during adipocyte differentiation.
Our results provide strong evidence that the AMP-activated protein kinase is a physiological regulator of HMG-CoA reductase. Incubation of rat hepatocytes with 20 mM fructose causes a large fall in ATP and concomitant rise in AMP level in the cell [7].
