The Epstein-Barr virus latent membrane protein 1 induces expression of the epidermal growth factor receptor.
The Epstein-Barr virus (EBV)-encoded LMP1 protein is an important component of the process of transformation by EBV. LMP1 is essential for transformation of B lymphocytes, most likely because of its profound effects on cellular gene expression. Although LMP1 is expressed in the majority of nasopharyngeal carcinoma (NPC) tumors, the effect of LMP1 on cellular gene expression and its contribution...
متن کاملEpstein-Barr virus latent membrane protein 1 induces CD69 expression through activation of nuclear factor-κB.
Latent membrane protein‑1 (LMP-1) of Epstein‑Barr virus (EBV) promotes tumorigenesis. Here, we report that LMP-1 activates the immunoregulatory molecule CD69 gene transcription through a nuclear factor-κB (NF-κB)‑dependent pathway. CD69 expression was upregulated in LMP-1‑expressing EBV-immortalized human B-cell lines and an EBV-positive Burkitt's lymphoma cell line. LMP-1 expression increased ...
متن کاملEpstein-barr virus latent membrane protein 1 induces and causes release of fibroblast growth factor-2.
We have shown that the EBV oncoprotein, latent membrane protein 1 (LMP1), induces a constellation of tumor-invasiveness factors. Fibroblast growth factor (FGF)-2 is angiogenic as well mitogenic. Although FGF-2 does not contain a hydrophobic signal sequence for secretion, FGF-2 is released extracellularly. However, the mechanism by which FGF-2 is released is unclear. Here we show first that LMP1...
متن کاملEpstein-Barr virus regulates STAT1 through latent membrane protein 1.
This study shows a mechanism for the increase of signal transducer and activator of transcription 1 (STAT1) in Epstein-Barr virus-immortalized cells. Latent membrane protein 1 (LMP-1) expression was sufficient to induce STAT1 expression, DNA binding, and transcriptional activity. LMP-1-expressing cells can induce an increase in STAT1 expression in LMP-negative cells in the same culture, suggest...
