Enzyme once thought harmful to Alzheimers patients now appears key to future treatment
...hen a nerve is cut or injured, the neuron produces extra
galanin, possibly to repair or modulate the damage. The production of galanin may be one way that the body tries to repair nerve damage. Unfortunately, accepted literature states when the onset of AD occurs, galanin hyperinnervation (excessive suppl...
Muscle gene influences fat storage in mice; may be target to prevent or treat obesity and diabetes
...n, in addition to having less fat, may have enough extra
muscle mass to make up for decreasing sensitivity to insulin as they gain weight. In type 2 diabetes, tissues, especially muscle, stop responding to insulin and hence don't soak up sugar from the blood. Uncontrolled type 2 diabetes can lead to bl...

Researchers identify gene required for marking DNA as having come from the mother
