Paying particle attention to novel melanoma treatment strategies

Abstract

Malignant melanoma remains the deadliest form of skin cancer because of its highly aggressive nature and the lack of effective treatments. Recent investigations into alternative treatment strategies have highlighted the exciting potential of nanoparticles to increase melanoma cell delivery and the efficacy of small interfering RNAs (siRNAs) and pharmacological inhibitors. In this issue, Chen et al. report a new liposomal nanoparticle for c-Myc siRNA delivery, noting it to be highly effective in reducing c-Myc expression and inhibiting melanoma tumor growth in mouse models. This preclinical study underscores the importance of investigating nanoparticle treatment options for chemoresistant melanomas. © 2010 The Society for Investigative Dermatology.
