The latent membrane protein 1 (LMP-1) of Epstein-Barr virus (EBV) functionally resembles a constitutively active, CD40-like receptor and contributes to the maintenance of proliferation of EBV-infected primary human B lymphocytes. LMP-1 is targeted to the plasma membrane, where it binds TRAF, TRADD, and JAK molecules to activate NF-kappaB-, AP-1-, and STAT-dependent pathways as does CD40. Yet LM...

Can location-based mobile promotion (LMP) trigger contemporaneous and delayed sales purchases? As mobile technologies can reach users anywhere and anytime, LMP becomes a promising new channel. We unravel the dynamic sales impact of LMP, on the basis of a randomized field experiment with 22,000 mobile users sponsored by one of the largest mobile service providers in the world. Our identification...

The latent membrane protein-1 (LMP-1) of Epstein-Barr virus (EBV) contributes to the proliferation of infected B lymphocytes by signaling through its binding to cellular signaling molecules. It apparently mimics members of the tumor necrosis factor receptor family, in particular, CD40, by binding a similar set of cellular molecules as does CD40. LMP-1 differs dramatically in its structure from ...

Epstein-Barr virus (EBV) nuclear antigen 3C (EBNA-3C) is essential for EBV-mediated immortalization of human B lymphocytes and regulates both the cell cycle and transcription. Transient reporter gene assays have implicated a pivotal role for EBNA-3C in the regulation of transcription of the majority of latency-associated genes expressed during the EBV growth program, including the viral oncopro...

Papillary serous low malignant potential (LMP) tumors are characterized by malignant features and metastatic potential yet display a benign clinical course. The role of LMP tumors in the development of invasive epithelial cancer of the ovary is not clearly defined. The aim of this study is to determine the relationships among LMP tumors and invasive ovarian cancers and identify genes contributi...

Epstein-Barr virus (EBV) latency has been associated with a variety of human cancers. Latent membrane protein 1 (LMP-1) is one of the key viral proteins required for transformation of primary B cells in vitro and establishment of EBV latency. We have previously shown that LMP-1 induces the expression of several interferon (IFN)-stimulated genes and has antiviral effect (Zhang, J., Das, S. C., K...

The phylogeny and evolution of Epstein-Barr virus (EBV) genetic variation are poorly understood. EBV latent membrane protein-1 (LMP-1) gene sequences are especially heterogeneous and may be useful as a tool for EBV genotype identification. Therefore, LMP-1 sequences obtained directly from EBV-infected human tissues were examined by PCR amplification and cloning. EBV genotypes were defined as "s...

Latent membrane protein 1 (LMP-1) of Epstein-Barr virus (EBV) promotes tumorigenesis by inhibiting apoptosis. We show that an important antiapoptotic activity of LMP-1 is the inhibition of Bcl2-associated protein X (Bax), a potent proapoptotic protein. BAX expression was regulated by LMP-1 activation of nuclear factor kappaB (NF-kappaB) via the C-terminal activation region 1 (CTAR-1) and CTAR-2...

PURPOSE EBV-latent membrane protein-1 (LMP-1) is often expressed in Hodgkin and Reed-Sternberg (HRS) cells of classical Hodgkin's lymphoma (cHL), but its clinical significance is controversial. We correlated LMP-1 with presenting features, including serum interleukin 10 levels and clinical outcome. EXPERIMENTAL DESIGN Patients were eligible if they had biopsy-proven cHL, were untreated, HIV-1...
