Gaining Control of the Gene Responsible for Apoptosis Essay -- Apoptos

Gaining Control of the Gene Responsible for Apoptosis When we gain control of the gene responsible for the phenomenon of apoptosis, we will be in control of aging. We are finding more evidence every day, indicating genetic links to all sorts of factors in the human being. We are just now beginning to scratch the surface of our own genetics. A landmark discover has just been unveiled: In February [2001], the two groups charting the human genome published their results—the entire 3 billion base pair sequence. The only definitive conclusion so far: Humans are far more complicated than we thought. †¦Eric Lander, director of the Whitehead Center for Genome Research in Cambridge, Massachusetts †¦ adds: â€Å"within a decade, we will understand a lot about the causes of diseases. Understanding, however does not translate into cures.† (Sinha 43) With this research we will uncover more factors that our genetic code regulates, many factors that were previously believed to be random events. Spontaneous cell death, as it turns out is not spontaneous at all, but genetically predetermined at conception. Cell death is an essential part of life. The cells in our bodies are constantly dividing, producing hundreds of thousands of new cells every second. To maintain balance, for every new cell, another cell must die. Our cells are programmed to kill themselves through a process called apoptosis. This in-built program of cell suicide prevents cancer by eliminating cells with damaged genes (Cotran 18). Similarly, our bodies replace cells with a new type of cell when a change is needed, such as during embryonic development (Cotran 18). To illustrate this point, we look at one of Dr. Adamchak’s â€Å"stories of physiology,† as taught from Martini... ... Schneider, Edward, L.
