Insulin signal transduction pathway (also known as glucose homeostasis) also exhibits oscillatory behavior. On a pathological basis, this topic is crucial to understanding certain disorders in the body such as diabetes, hyperglycemia and hypoglycemia. The functioning of a signal transduction pathway is based on extra-cellular signaling that in turn creates a response which causes other subsequent responses, hence creating a chain reaction, or cascade. During the course of signaling, the cell uses each response for accomplishing some kind of a purpose along the way. Insulin secretion mechanism is a common example of signal transduction pathway mechanism. Insulin is produced by the pancreas in a
Insulin analog required throughout the day representing about 50% of daily insulin requirement, the insulin amount needed at mealtime makes up for the remaining 50%. Non hexameric insulins (monomeric insulins) were developed to be faster acting and to replace the injection of normal unmodified insulin before a meal. There are phylogenetic examples for such monomeric insulins in animals. All insulin analogs must be tested for carcinogenicity, as insulin engages in cross-talk with IGF pathways, which can cause abnormal cell growth and tumorigenesis. Modifications to insulin always carry the risk of unintentionally enhancing IGF signalling in addition to the desired pharmacological properties. There
