Abstract or Artist's Statement

Multiple Myeloma is cancer of plasma cells and is known to be highly invasive. Multiple Myeloma makes up 1% of cancer diagnosis in western countries and affects men more predominantly than women. The American Cancer Association estimates that 32,110 new cases will be diagnosed in the United States in 2019. Lenalidomide is one of the main therapies used for multiple myeloma patients, but it has toxic side effects such as thrombocytopenia, neutropenia, and anemia. The purpose of the study is to investigate new cytotoxic agents for the treatment of multiple myeloma. In addition to lenalidomide alone, this study examined the effects of doxycycline alone and in combination with lenalidomide. Lenalidomide cell cultures were treated at concentrations from 0.5μM to 10μM on untreated 24 well plates and doxycycline concentration ranging from 10μM-80μM. Following incubation, cell viability was tested using MTT assay and the samples were analyzed using spectrophotometry. When compared to lenalidomide, doxycycline monotherapy showed a greater decrease in overall cell viability in preliminary results. Our results show that there is benefit of using 10μM of Doxycycline at higher concentration of 5μM and 10μM of lenalidomide. The potential decrease in the concentration of lenalidomide used by adding doxycycline, may reduce the toxic side effects of lenalidomide. Further studies are necessary to confirm these preliminary results and investigate the mechanism of action in order to determine optimal combinations of these drugs.
