Abstract: Lung cancer is the leading cause of cancer related death in the United States killing over 130,000 people each year. While a combination of chemo and radiation therapy may be effective, surgery is still required for many patients. Without surgery, the disease may progress and lead to metastases. We sought to determine if treatment with anti-non-muscle myosin IIA antibody would inhibit movement of the cells in the presence and absence of glabridin (an isoflavonoid compound shown to inhibit cell migration by inhibiting myosin). We compared inhibition by glabridin to that of an anti-non-muscle myosin IIA antibody and a combination therapy of both at 12 and 24 hours post wound creation. Cells that took up the anti-non-muscle myosin IIA antibody were greatly inhibited in motility and exhibited no significant change in wound healing. Glabridin treatment resulted in a dramatic increase in wound size within 12 hours and regeneration within 24 hours. The greatest decrease in motility was observed in cells treated with the combination of both glabridin and anti-non-muscle myosin IIA antibody. By 24 hrs, cell migration had halted due to death of the cells resulting from this combination. Further testing needs to be done to determine a safe mode of delivery of the combination therapy to ensure only local distribution. Controlled release drug delivery depot systems have been used as a means to provide local release of drugs intra-tumorally or adjacent to the cancerous tissue after surgical resection and have great potential.
