Abstract

Both human γ‐herpesviruses, Epstein‐Barr virus (EBV) and Kaposi's sarcoma‐associated herpesvirus (KSHV) induce neoplasia. Burkitt's and Hodgkin's lymphomas harbor EBV sequences, while KSHV has been associated with Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), and multicentric castleman's disease (MCD). Each of these γ‐herpesvirus‐associated malignancies displays typical characteristics of neoplasia, such as angiogenesis and cell survival. One enzyme commonly overexpressed in breast, prostate, and colon cancers is cyclooxygenase‐2 (COX‐2). Recently, COX‐2 overexpression has been reported in herpesvirus infections in vitro. This review will outline potential mechanisms by which COX‐2 may participate in herpesvirus‐induced neoplasia. Microsc. Res. Tech. 68:120–129, 2005. © 2005 Wiley‐Liss, Inc.
