alpha carboxylase/hypoxia

The presence of a 280,000 M(r) isoform of acetyl-CoA carboxylase (ACC-280) in the cardiac myocyte suggests that heart muscle is capable of malonyl-CoA synthesis. Cellular factors which regulate activity of ACC-280 are unknown. We have employed a neonatal rat cardiac myocyte culture (where the

Hypoxia is associated with aggressive phenotype and poor prognosis in prostate cancer (PCa) patients suggesting that PCa growth and progression could be controlled via targeting hypoxia-induced signaling and biological effects. Here, we analyzed silibinin (a natural flavonoid) efficacy to target

Primary hepatocyte culture is an important in vitro system for the study of liver functions. In vivo, hepatocytes have high oxidative metabolism. However, oxygen supply by means of diffusion in in vitro static cultures is much less than that by blood circulation in vivo. Therefore, we investigated

During metabolic stress, such as ischemia or hypoxia, glucose becomes the principal energy source for the heart. It has been shown that increased cardiac glucose uptake during metabolic stress has a protective effect on cell survival and heart function. Despite its physiological importance, only

AMP-activated protein kinase (AMPK) is a heterotrimeric enzyme that is expressed in most mammalian tissues including cardiac muscle. Among the multiple biological processes influenced by AMPK, regulation of fuel supply and energy-generating pathways in response to the metabolic needs of the organism
