What are the different types of growth hormone similar to insulin?

There are two primary types of growth hormone similar to insulin: insulin growth factor 1 (IGF-1) and insulin growth factor 2 (IGF-2). Both of these insulin growth hormones are naturally produced by different types of cells and have the same molecular structure as hormonal insulin, ie their names. They also have similar functions as insulin and are vital elements in human growth and memory. IGF-1 and IGF-2 are also known as Somatomedin C and Somatomedin A and or. dubbed as "serum factors". Some laboratory experiments included cultivation of insulin with a serum filled with an antibody to remove all insulin Functions, but some functions remained and were attributed to "insulin similar" elements. After more than two decades, scientists have beenolated and characterized by growth hormone similar to insulin or insulin similar to growth factors (IGF).

between two igF, IGF-2 plays a more pronounced role during pregnancy, or a period when the fetus in the womb is still evolving. Its presence indicates cells to propagate and divide into different types to form solid tissues. Insulin growth hormone also promotes progesterone secretion, important hormone for fetal development and menstruation. Studies at the end of 2000 have found that IGF-2 may be an important factor in the treatment of Alzheimer's disease and other memory disorders such as post-traumatic stress disorder. The IGF-2 gene or a gene that helps to produce IGF-2 is inherited from both male and female parent, but only a copy from the male parent becomes active in the fetus.

Unlike IGF-2, IGF-1 is more active in the adult body and its presence affects the growth of the musculoskeletal system, nervous system and vital organs such as kidneys, liver and lungs. In fact, almost every type of cell in the body needs to develop IGF-1. The amount of IGF-1 produced in the body is usually the highest during adolescents and then graduallydecreases. Many studies have shown that children who are shorter than usual may have an insufficient amount of growth hormone of similar insulin and experimental IGF-1 therapy have somehow increased their height. Interestingly, some studies have found that reduced IGF-1 levels in adults may delay the symptoms of aging, cause the right weight loss and promote longevity.
