The Anti-Apoptotic Role of EBV-LMP1 in Lymphoma Cells.

ABSTRACT:

Background

Epstein-Barr virus (EBV) has been indicated in the development of some tumors, including lymphoma. However, the potential role of latent membrane protein 1 (LMP1) encoded by EBV in the tumorigenesis of lymphoma remains debated. Herein, we examined the function of LMP1 in lymphoma.

Methods

The expression of LMP1 was downregulated or upregulated in EBV negative cell line SNT-8 and positive cell line KHYG-1, respectively. Subsequently, the cell viability, apoptosis, as well as the expression patterns of p53, mouse double minute 2 (MDM2), B-cell CLL/lymphoma 2 (Bcl-2) and NF-κB were evaluated. Next, the binding relationship between MDM2 and p53 along with p53 ubiquitination in cells was tested by Western blot and co-immunoprecipitation. Finally, the effects of LMP1 on
