Would occur for concentrations 10 [micro]g/L and 20 [micro]g/L excess of substrate (glucose) for the enzyme pyruvate kinase (which degrades glucose to pyruvate to borrow the Krebs cycle and the process of breathing with the formation energy ATP), may be this is due to saturation of receptors and therefore, part of the glucose escape hepatocytes experimentation by the mechanism of facilitated transport of glucose across the biological membrane to its action on PEPCK level explained above kernel this would explain the values of the variation of the high optical density of the extracts at concentrations 10 [micro]g/L and 20 [micro]g/L in contrast to those obtained for concentrations 2 [micro]g/L and 5 [micro]g/L.
Fructose-1,6-bisphosphatase activity was measured by the method of Gancedo and Gancedo (1971), pyruvate kinase activity was estimated by the method of Pogson and Denton (1967), lactate dehydrogenase activity was estimated by the method of King (1965), glycogen synthase activity was estimated by the method of Leloir and Goldemberg (1962), glycogen phosphorylase activity was estimated by the method of Cornblath et al.
Figure 2 showed that enzymes related to glycolysis (fructose-bisphosphate aldolase (GI: 27469074), glyceraldehyde 3-phosphate dehydrogenase (GI: 27467475), enolase (GI: 27467479), pyruvate kinase (GI: 27468291)), the TCA cycle (succinyl-CoA synthase (GI: 27467842), and isocitrate dehydrogenase (GI: 27468288)) were downregulated at the post-exponential phase.
The enzymes particularly upregulated were hexokinase, aldolase, enolase, pyruvate kinase, and adenosine deaminase [7].
Oxidative stress drives activated FOXO1 to enter the cell nucleus, suppressing expression of genes involved in glucose metabolism, such as glucose transporter-2 (GLUT2) and pyruvate kinase (7).
