Choose a system (circulatory, pulmonary, muscular, skeletal, digestive, reproductive, etc). Find a health related illness (mitral valve prolapsed, asthma, muscular dystrophy etc) or a benefit (pregnancy) that is tied in with that system. What cutting edge research is currently being done regarding that illness/ benefit? Choose one paper or review on the subject. Provide details concerning the illness/ benefit at the tissue and cellular levels, including any signaling molecules that are important. Indicate also the broader impacts, that is, what potential benefits will come out of research in that area (more than one- ideally 3 or more). Maryah Barna Bio 102-5 23 April 2009 Diabetes Diabetes is a disease that has affected a large population all around the world. There are three major forms of it: diabetes mellitus type 1, diabetes mellitus type two, and gestation diabetes. Diabetes is caused by a deficiency of the pancreas that causes the ratio of glucose to insulin to get out of control. Since a large percentage of the population either already has the disease or is going to have the disease, there is a lot of research that is being done on the matter. Diabetes has three different forms: type one, type two, and gestational diabetes (Nordenson & Odle 2006). Type one is an autoimmune disorder that causes an insulin deficiency due to the continue destruction of pancreatic islet beta cells. The beta cells are housed in the pancreatic islets and secrete the hormone insulin when there are high levels of sugar in the blood. Insulin has more than just one function. It stimulates the glucose to enter into the cells where the glucose is used as a source of energy (Ehrlich A. & Schroeder, C. L. 2009). Also, insulin also stimulates the liver to convert the glucose back into glycogen: the storage form of glucose. The other cells that have a major function in the regulation of blood sugar levels are the alpha cells. These secrete the hormone glucagon within the pancreatic islets, which increases the blood sugar
