13 Mar 2008
Abstract excerpt
Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiologic agent associated with Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman's disease. Hypoxia-inducible factor-1 (HIF-1) is the master regulator of both developmental and pathologic angiogenesis, composed of an oxygen-sensitive alpha-subunit and a constitutively expressed beta-subunit. HIF-1 activity in tumors depends on the...
