(a) What enzyme mobilizes free fatty acids? (b) What activates/inactivates it? In gluconeogenesis, glucose is synthesized from ___ and amino acids. a) glycogenesis b) glycerol c) fermentation d) respiration e) catabolic f) glycogen g) carbon h) pyruvate ...
HIF-1 can decrease mitochondrial ROS production by inhibiting the uptake of pyruvate into the mitochondria through the expression of pyruvate dehydrogenase kinase-1 (PDK1), which inactivates PDH, thereby inhibiting the conversion of pyruvate to acetyl-CoA in the tricarboxylic acid cycle77 (Fig. 1)...
dominate the progression and regression of liver fibrosis [24,25]. Follistatin-like protein 1 (FSTL1) is thought to be a proinflammatory gene involved in macrophage polarization that accelerates the progression of liver fibrosis by promoting pyruvate kinase M2 (PKM2) phosphorylation...
PKB cell signaling is cell signaling that activates a protein known as Protein kinase B. Protein kinase B activates its targets by phosphorylation... Learn more about this topic: Cell Communication Concept & Examples from Chapter 8/ Lesson 1 ...
WUS is expressed in OC cells, and it changes the cell fate non-cell-autonomously and activates the expression of CLV3 by moving from the OC to the CZ. In return, CLV3 can repress WUS expression. This feedback regulation controls the cell number and cell niche size of SAM, and is ...
On the other hand, PFKL is feedback activated by F1,6BP, which auto-activates enzyme performance. When samples from women who did not have a subsequent cancer recurrence were tested using anti-PFKL antibodies, PFKL was found in the nucleoli of tumor cells (Figure 4C), where it co-localize...
Similarly, hyperglycemia caused by inadequate insulin action results in the activation of carbohydrate response element binding protein (CREBP), which activates L-type pyruvate kinase and lipogenic genes in hepatocytes [29].

In Bergmann glial cells, for example, kainate (that activates AMPA receptors present in these cells without triggering their desensitisation) induces [Na+]i transients with peak amplitudes ~ 25 mM [180], [181]. In hippocampal astrocytes specific inhibition of AMPA receptors with CNQX reduced the...
(YAP1), a critical organ size regulator, is also nuclearly localized68. Although no neighboring cells are lost in PHx, the change in shear stress due to increased blood flow activates YAP1 through the Hippo pathway69. Hepatocytes secrete various autocrine and paracrine factors, e.g., vascular...
Phosphorylation of glucose upon entering the cell has what effect? A. prevents glucose from leaving again B. activates the glucose for further reaction C. generates ATP D. cleaves the glucose to glyceraldehyde-3-phosphate E. Both A and B are correct. ...
