B-Raf-dependent expression of vascular endothelial growth factor-A in Kaposi sarcoma-associated herpesvirus-infected human B cells.

Kaposi sarcoma-associated herpesvirus/human herpesvirus 8 (KSHV/HHV-8) is etiologically linked to Kaposi sarcoma (KS), primary effusion lymphoma (PEL), and multicentric Castleman disease. Vascular endothelial growth factor-A (VEGF-A) is one of the essential factors required in KSHV pathogenesis, mainly due to its ability to mediate angiogenesis. In this report we analyzed the relationship betwe...

Raf-induced vascular endothelial growth factor augments Kaposi's sarcoma-associated herpesvirus infection.

Recombinant green fluorescent protein encoding Kaposi's sarcoma-associated herpesvirus (rKSHV.152) infection of beta-estradiol stimulated human foreskin fibroblasts (HFF) or HFF/DeltaB-Raf([FF]):ER (expressing a weaker form of B-Raf) could be enhanced to levels comparable to that of HFF/DeltaB-Raf([DD]):ER cells by pretreating cells with soluble vascular endothelial growth factor (VEGF). Conver...

NEOPLASIA Role of Vascular Endothelial Growth Factor/Vascular Permeability Factor in the Pathogenesis of Kaposi’s Sarcoma-Associated Herpesvirus-Infected Primary Effusion Lymphomas

Primary effusion lymphomas (PELs), which are rare lymphomas associated with Kaposi’s sarcoma-associated herpesvirus (or human herpesvirus-8) infection, present as malignant lymphomatous effusions in body cavities. Because PELs prefer liquid growth, we hypothesized that increased vascular permeability would be required for effusions to form. We found that the PEL cell lines BC-1, BCP-1, and BCBL...

The Kaposi’s Sarcoma-associated Herpes Virus G Protein-coupled Receptor Up- Regulates Vascular Endothelial Growth Factor Expression and Secretion through Mitogen-activated Protein Kinase and p38 Pathways Acting on Hypoxia-inducible Factor 1a

The elucidation of the molecular mechanisms governing the transition from a nonangiogenic to an angiogenic phenotype is central for understanding and controlling malignancies. Viral oncogenes represent powerful tools for disclosing transforming mechanisms, and they may also afford the possibility of investigating the relationship between transforming pathways and angiogenesis. In this regard, w...
