First paragraph (this article has no abstract)In her letter, recently published in Breast Cancer Research, María Victoria Preciado points out that some published evidence suggests a possible association of breast cancer with Epstein–Barr virus (EBV) [1]. EBV DNA has been detected by PCR in up to 50% of cases (for a review see [2]), and expression of the EBV-encoded nuclear antigen EBNA1 has been demonstrated in approximately 40% of cases by immunohistochemistry using the mAb designated 2B4 [3]. In combination, these findings seem to implicate EBV in the pathogenesis of breast carcinoma. Interestingly, however, most investigators agree that the EBV-encoded RNAs (EBERs), a hallmark of latent EBV infection, are not detectable in breast carcinoma tumour cells [2]. |
