6. Regulation of energy metabolism in tumor cells : the role of hexokinase
Sammanfattning : Changes in glucose metabolism are among the most universal andfundamental metabolic alterations observed in cancer cells. Hexokinase isthe initial regulatory enzyme which controls the rate of glucose entranceinto the glycolytic pathway. The content of hexokinase in tumor cells iselevated, and most of the enzyme is bound to mitochondria. LÄS MER
7. Energy metabolism and angiogenesis in atherosclerosis and cancer
Sammanfattning : Energy metabolism requires supply of glucose and oxygen. In atherosclerotic plaques and cancer tumors, there are local areas with mismatch in demand and supply of oxygen and nutrients. The resulting cellular energy imbalance may promote energy failure and stimulation of angiogenesis. LÄS MER
8. Glutamate Turnover and Energy Metabolism in Brain Injury : Clinical and Experimental Studies
Sammanfattning : During brain activity neurons release the major excitatory transmitter glutamate, which is taken up by astrocytes and converted to glutamine. Glutamine returns to neurons for re-conversion to glutamate. This glutamate-glutamine cycle is energy demanding. LÄS MER
9. Energy metabolism in skeletal muscle during ischemia and reperfusion. Experimental and clinical aspects
Sammanfattning : Microsurgical operations, using free vascularised transfer of tissues, induce an obligatory period of ischemia followed by reperfusion. The degree of ischemia and reperfusion injury is dependent on the ischemia time. LÄS MER
10. Myocardial creatine metabolism in experimental infarction and heart failure
Sammanfattning : The failing heart is characterized by changes in structure, function and metabolism. All these changes are usually defined as pathologic remodelling. An important part of this negative remodelling process is disturbances in the myocardial energy metabolism. LÄS MER
