<;P>;PROBLEM TO BE SOLVED: To provide a composition for regulating marker protein levels widely usable in food/drink, feed, quasi-drugs, pharmaceuticals, etc. because of being high in safety and practicability as well as promising the effects of preventing aging-associated senility and diseases. <;P>;SOLUTION: The composition is such as to function to regulate the quantity change of a cell death (especially apoptosis) marker protein as aging proceeds so as to diminsh the change. This composition contains an amla (Embilica officinale) extract as active ingredient. By the way, the cell death marker protein means, e.g. a protein that is present in cells and functions on mitochondria envelope, for example, being Bax or Bcl-2 protein. <;P>;COPYRIGHT: (C)2007,JPO&INPIT
