UPDATE: SEPTEMBER 2007
We have developed a system that can efficiently deliver siRNA to defective primary epidermal keratinocytes isolated from our mouse model that mimics EHK. This delivery system was derived from a lentiviral vector. siRNAs are small therapeutic molecules that have been designed to specifically inhibit the expression of the mutant form of keratin 10 that is present in many EHK patients. We are currently testing whether the introduction of mutant keratin 10 specific siRNA into EHK keratinocytes will allow these cells to form a normal epidermis when they are grafted to form skin on a mouse. We have also begun to test a new delivery system that may allow siRNA to be delivered topically. This system utilizes nanotechnology, and we hope that this system will penetrate the thick hyperkeratotic skin that develops in areas prone to mechanical injury in EHK patients.
