In vitro and in vivo assessments suggest that proteasome inhibitors may be useful for modulating wound healing. Methods. Proteasome Inhibitor I was used to assess the potential utility of proteasome inhibitors in improving wound healing in a standard rat model. Bilateral, 6 cm incisions were made 1 cm lateral to the spine of adult male Sprague Dawley rats. Animals were randomly assigned to 1 of 3 groups: no treatment (n ≤ 15), low concentration (1% w/v, n ≤ 15), or high concentration (5% w/v, n ≤ 15). Treatments were applied to the left side incision at 0 hours, 24 hours, and 48 hours. Right-side incisionsreceived a vehicle, dimethyl sulfoxide, alone and independent of the assigned group, serving as both external and internal controls. Rats were sacrificed at days 7, 14, and 28 (n ≤ 5 per group) and wounds subjected to mechanical testing and histology. Results. No significant intergroup difference existed at 7 and 14 days. On day 28, a dosedependent increase in tensile strength with increasing Proteasome Inhibitor I was observed. Conclusion. Results suggest dimethyl sulfoxide was not the ideal vehicle and additional improvement may be realized by optimizing the delivery method.
