The researchers used a technique called RNA interference to silence the expression of a gene in cow's that is responsible for the production of bovine insulin. This allowed them to insert a human insulin gene into the cow's genome, which was then expressed in the cow's mammary glands.
The researchers were able to produce human insulin in the milk of four cows. The insulin was purified from the milk and found to be biologically active.
This study is a significant step forward in the development of a new way to produce human insulin. Currently, human insulin is produced using a fermentation process that is expensive and time-consuming. The ability to produce human insulin in cow's milk could provide a more affordable and efficient way to produce this important medication.
The researchers say that more research is needed before human insulin produced in cow's milk can be used to treat patients. However, they are optimistic that this new technology could eventually lead to a new treatment option for people with diabetes.
Diabetes is a chronic disease that affects how your body turns food into energy. With diabetes, your body either doesn't make enough insulin or doesn't use insulin well. Glucose, or sugar, builds up in your blood instead of being used for energy.
Insulin is a hormone that helps glucose get from your blood into your cells. People with diabetes need to take insulin to help control their blood sugar levels.
Insulin is currently produced using a process called recombinant DNA technology. This process involves inserting the human insulin gene into a yeast cell, which then produces insulin. The insulin is then purified and packaged for use.
Recombinant DNA technology is a complex and expensive process. As a result, human insulin is a relatively expensive medication. The ability to produce human insulin in cow's milk could provide a more affordable alternative to recombinant DNA technology.
