When a massive star ends its normal life, it collapses by blowing off its outer layers, producing a very dense cloud of neutrons, leaving a very dense core...
...really opened up the field of oncagene proteins," Rohrschneider says. "He was able to identify the gene but now must use this to see how it turns a normal cell to a cancerous...
...Right now, we may be nearing the end of identifying oncagenes," Erikson says. "This is the first step. Next we must understand how oncagene products change the way a normal cell behaves...
Once oncagenes are understood, the final step will be to design a drug that inhibits the protein formation process. This, however, may be the most difficult part of the puzzle, Cantley says, since all cells have these proteins, and if they are attacked and destroyed, normal body cells may fall victim to the drugs as well...
...meantime have ade a number of advances in understanding the protein's functions. Most commonly, the protein within a cell adds a phosphorous atom to another protein known as amino acid tyrosine. This seemingly minor action, however, has intriguing effects on living tissues and is somehow related to normal growth in skin cells...
