Glutaminase is an enzyme that converts glutamine into glutamate, a secondary fuel for cancer cells. Stress and certain drugs can deplete it and muscle wastage is a common result. Where nitrogen is needed by the body – for example, in wound repair – a third of this comes from glutamine. It can be provided intact or in bonded form. Glutamate is also essential for brain and nervous function. It is the major transmitter in nerves. However, glutamate uptake by the brain across the Blood Brain Barrier is very low.
Few, if any other diagnoses cause so much emotional distress, both for people with cancer and for their loved ones. To begin with article 1, go to ” What Causes Cancer? This is partly due to the potentially deadly nature of the condition, and partly due to the misery associated with most conventional cancer treatments—surgery, chemotherapy, and radiation.
Biologists have known for nearly a century that some types of cancer cells consume significantly more glucose than normal cells. Cancer cells, however, function quite differently. They rely heavily upon another energy-producing process in the metabolism of sugar called glycolysis. This produces energy faster, but also extracts much less of it from the sugar molecule. It has never been entirely clear why the difference exists. Cancer cells presumably need a considerable amount of energy in order to grow and proliferate throughout the body. How do they do it? A new paper in the journal Cell Metabolism attempts to address this question. In doing so, authors Craig Thompson and Natasha Pavlova launch a novel explanation for the origin of cancer itself. One of the great fundamental challenges of biology is how multicellular organisms evolved, and how these clusters of cells manage to function together harmoniously. Thompson has argued that the cells that make up multicellular organisms operate in a fundamentally different way than their single-celled counterparts.
