OBJECTIVE p38 mitogen-activated protein kinase (p38 MAPK) and AMP-activated protein kinase (AMPK) are activated by, and influence sensitivity to, myocardial ischemia. Recently a number of studies have suggested that AMPK may participate in the activation of p38 MAPK. We therefore examined whether AMPK may be the principal "ischemia sensor" responsible for p38 MAPK activation during myocardial i...
The AMP-activated protein kinase (AMPK) is the central component of a protein kinase cascade which plays an important role in the regulation of many different aspects of lipid metabolism [1,2]. AMPK is activated 50to 100-fold by phosphorylation by an upstream protein kinase, AMPK kinase (AMPKK) [3]. The key regulators of the AMPK cascade currently appear to be S’-AMP and ATP. AMP activates the ...
BACKGROUND The yeast SNF1 protein kinase and the mammalian AMP-activated protein kinase are highly conserved heterotrimeric complexes that are "metabolic master switches" involved in the switch from fermentative/anaerobic to oxidative metabolism. They are activated by cellular stresses that deplete cellular ATP, and SNF1 is essential in the response to glucose starvation. In both cases, activat...
Three protein kinases were separated from bovine epididymal spermatozoa by using DEAE-Sephadex ion exchange chromatography and Sephadex G-100 gel filtration. The molecular weights of these three kinases were estimated to be 120,000, 78,000 and 56,000 by the use of Sephadex G-100 gel filtration. The activity of all three kinases was greatly enhanced by cyclic adenosine 3’,5’-monophosphate (cycli...
BACKGROUND Acute coronary syndrome is a leading cause of death in developed countries. Follistatin-like 1 (FSTL1) is a myocyte-derived secreted protein that is upregulated in the heart in response to ischemic insult. Here, we investigated the therapeutic impact of FSTL1 on acute cardiac injury in small and large preclinical animal models of ischemia/reperfusion and dissected its molecular mecha...
beauveria spp. as entomopathogenic fungi have extremely diverse insect host ranges.here, a comparative transcript analysis of a bassiasin i (bsni), a dipeptidyl peptidase (dpp), a cytochrom p450 monooxygenase (cyp52), a mitogen activated protein kinase (mapk), and a neuronal calcium sensor 1 (ncs) in two isolates of beauveria bassiana., with low and high virulence, were carried out. for this, i...
Background: Both mitochondrial dysfunction and aerobic glycolysis are signs of growing aggressive cancer. If altered metabolism of cancer cell is intended, using the glycolysis inhibitor (2-deoxyglucose (2DG)) would be a viable therapeutic method. The AMP-activated protein kinase (AMPK), as a metabolic sensor, could be activated with metformin and it can also launch a p53-dependent metabolic ch...
Two voltage-activated calcium currents, a transient T-type and a PL-sustained type, have been measured in isolated, cultured white bass horizontal cells. These two voltage-activated calcium currents were found to be modulated by two independent second-messenger systems. Furthermore, activation of either second-messenger system led to similar changes in calcium current activity. Activation of th...
