Molecular and epidemiological evidence links Kaposi sarcoma-associated herpesvirus (KSHV) to a number of malignancies of endothelial or B cell origin. As for most virus-associated cancers, however, the tumor initiating and promoting events remain poorly understood. Given the emerging role of epigenetic alterations as drivers of human cancers, an interesting (and as of yet under-explored) hypothesis is that viral manipulation of host cell chromatin may contribute to the pathogenesis of KSHV-associated tumors. We here review the current knowledge regarding the interplay between KSHV-encoded factors and host chromatin and discuss how epigenetic alterations may contribute to the pathogenesis of KSHV-associated tumors.
