Though EBNA1 is a well-characterized protein, its role in oncogenesis is less well defined. It is consistently expressed in EBV-associated tumors. [1] EBNA1 is the only identified latent protein-encoding genes that it consistently expressed in Burkitt's lymphoma cells [6] and is believed to contribute to EBV malignancies through B cell-directed expression.
Molecular classification of breast cancer from mRNA expression profiles. DNA microarrays have compared normal cells to breast cancer cells and found differences in the expression of hundreds of genes. Although the significance of many of those genetic differences is unknown, independent analyses by different research groups has found that ...
Epstein–Barr virus–associated lymphoproliferative diseases (also abbreviated EBV-associated lymphoproliferative diseases or EBV+ LPD) are a group of disorders in which one or more types of lymphoid cells (a type of white blood cell), i.e. B cells, T cells, NK cells, and histiocytic-dendritic cells, are infected with the Epstein–Barr virus (EBV).
In 2009, a case-control study of 187 triple-negative breast cancer patients described a 2.5 increased risk for triple-negative breast cancer in women who used oral contraceptives (OCs) for more than one year, compared to women who used OCs for less than one year or never. [12] The increased risk for triple-negative breast cancer was 4.2 among ...

Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.

The Epstein–Barr virus–encoded small RNAs (EBERs) are small non-coding RNAs localized in the nucleus of human cells infected with Epstein–Barr virus (EBV). First discovered in 1981, EBERs are the most abundant RNAs present in infected cells. [1]
