Targeting Cathepsin K to Facilitate Wound Healing

UW ID: 16-113

Description of Technology

          Impaired wound healing is a serious complication in people with diabetes. Wounds not healing in diabetic patients leads to 70,000 amputations annually in the United States. Of these amputations, 85% of these could have been averted with better prevention of wound recurrences.

          One critical part of wound healing is collagen, which is a main structural protein in connective tissues. Decreased collagen in a wound has been associated with impaired wound healing. In order to introduce more collagen to improve wound healing, one approach has been to use collagen wound dressings to increase levels in the wound. The main problem with this strategy is that the introduced extra collagen is still degraded the same as the internal collagen. Another method to improve wound healing is a drug called Becaplermin. This drug is the only FDA approved drug for treating diabetic ulcers and works by improving the collagen synthesis. The limitation to this treatment is an increased risk of cancerous tumors.

          Researchers at the University of Wyoming have been analyzing wound healing and have found that cathepsin K, a major enzyme, degrades proteins such as collagen. Since collagen is a major factor in wound healing, its degradation adversely affects wound healing. The researchers have invented a way to target and stop cathepsin K in specific locations around a wound. This would stop cathepsin K from degrading collagen so it could still heal the wound effectively. This invention could save many diabetic patients from hospitalization and amputations.



          This invention can be used to target and suppress the enzyme cathepsin K. Doing this would help to improve wound healing in diabetic patients.
