For a very long time I have been using Diabetes as an example of a disorder that is caused by a mutation in the insulin gene. This mutation would stop the cells from making insulin, and a diabetic might need daily insulin injections to regulate their sugar levels properly. I don’t know what took me so long to realize that this was completely wrong. That while some diabetics are insulin dependent, it is because their insulin-producing cells of the pancreas are being completely destroyed by the immune system. And while they still aren’t sure about why these cells are being More >
Insulin, a hormone produced by the pancreas, signals cells to remove glucose from the blood and store it as glycogen. Glucagon is a protein also produced by cells in the pancreas but it has the opposite effect of insulin. When blood glucose levels are low, glucagon causes the breakdown of glycogen into glucose that is then released into the blood. The insulin is made in beta cells, where as the glucagon is made in alpha cells. In patients with type 1 diabetes, the immune system attacks the beta cells, eliminating insulin production.
Scientists from the University of Geneva have shown that More >
Having an edge on the stock market can allow one to make hundreds, thousands or even millions of dollars. But rarely do we think of having an edge on life. Since the sequencing of the human genome our understanding of human genes and their interaction has grown. Geneticists now have the capability to analyze genetic make-ups, and elucidate what genetic patterns will evolve into certain conditions or disease states.
Any individual has a unique genetic profile different from that of another person. Contained within these differences are unique genetic variations that may make a person more susceptible to diseases such as More >
