Lee Rannals for redOrbit.com — Your Universe Online Boosting the activity of a particular enzyme can help block tumors from growing, according to research published in Nature Chemical Biology. Cancer cells use up most of their energy by reproducing themselves, but in order to do this they must produce new cellular building blocks like DNA, carbohydrates and lipids. Biologists found that jacking up the activity of the enzyme pyruvate kinase can disrupt the production of tumors...

Our cells breathe and digest, as does the organism as a whole. They indeed use oxygen to draw the energy contained in the nutrients they ingest, before discarding the waste, as carbon dioxide and water. Glucose is a preferred nutrient for the cells. Its digestion occurs in the cytoplasm, in the absence of oxygen, and leads to the formation of pyruvate and a small amount of energy. Pyruvate is then carried into mitochondria, the cell's power plants, for a complete burning, thus providing a...

Cancer-cell quirk could be exploited to develop new drugs that starve tumors In a paper appearing in the Sept. 16 online edition of Science, Matthew Vander Heiden assistant professor of biology and member of the David H. Koch Institute for Integrative Cancer Research at MIT and researchers at Harvard University report a previously unknown element of cancer cells' peculiar metabolism. They found that cells can trigger an alternative biochemical pathway that speeds up their metabolism and...

Researchers from CIC bioGUNE's Structural Biology Unit and Columbia University (New York) have conducted a joint research project, published in the prestigious scientific journal Structure, to gain in-depth knowledge of the structure of pyruvate carboxylase when it is in solution (in the "natural" state).Pyruvate carboxylase is a metabolic enzyme that plays a fundamental role in the metabolism of fatty acids (the components of fats) and sugars. When its function is not adequately performed...

A temporary under-the-skin sensor could monitor a variety of health indicators for soldiers, athletes, diabetics, infants, and critically ill patients without wires and at a distance, according to a team of Penn State chemical engineers. "We were asked to develop micro sensors for metabolic monitoring of troops," says Dr. Michael Pishko, professor of chemical engineering and materials science and engineering. "These implantable sensors are intended to monitor the physiology of troops in the...
