Human insulin production by genetic engineering. Insulin is a hormone produced by β-cells of islets of Langerhans of pancreas. It was discovered by sir Edward Sharpey Schafer (1916) while studying Islets of Langerhans. Pancreas is a mixed gland situated transversely across the upper abdomen behind stomach and spleen.

As a result some patients were allergic to insulin sourced from animals and had damaging side effects as a result of treatment from these injections. The solution to this problem was solved by genetic engineering. The animation below shows how human insulin is produced by genetic engineering.

This disease kills many people in the world every year.Insulin has been used in the treatment of diabetes mellitus since 1922 when Leonard Thompson became the first human to receive an injection of man-made insulin. Production of Genetic Engineered Insulin. 1. Human insulin is extracted from pancreas cells and an insulin-producing gene is ...

The Genetic Engineering of Insulin In the 1970s, scientists developed a way to produce human insulin, without using humans or animals. First, they genetically engineered pieces of DNA that coded ...

How does genetic engineering work? To help explain the process of genetic engineering we have taken the example of insulin, a protein that helps regulate the sugar levels in our blood. Normally insulin is produced in the pancreas, but in people with type 1 diabetes there is a problem with insulin production.

It has been 35 years since genetically engineered insulin was approved by the FDA in a process that was quick and efficient -- particularly by today's regulatory standards.

Since the early 1920s, diabetic patients were treated with insulin, which was purified from bovine or porcine pancreas. The development in the field of genetic engineering allowed the production of insulin in E. coli and yeast, which have been approved for therapeutic applications in human by FDA [14,15].. Nowadays, recombinant human insulin is mainly produced either in E. coli or ...

As these modified bacteria grow, they produce human insulin. This protein can be purified and supplied to diabetics. The process of genetically engineering bacterial cells is shown in the diagram ...

Recombinant DNA is a technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene. Scientists build the human insulin gene in the laboratory ...

Genetically engineered Insulin : Humulin, preferred over old animal based products. Structure of Insulin. Insulin is a proteinaceous hormone secreted by beta-cells of islets of langerhans of pancreas. Insulin controls, blood sugar level and when there is less secretion of insulin, it results in diabetes (high blood- sugar level).
