HIV and AIDS Malignancy Branch

HAMB Picture

Research

The HIV and AIDS Malignancy Branch (HAMB) conducts laboratory and clinical research in AIDS-related malignancies, HIV disease, and viral-induced tumors. The principal aims of this translational research program are to develop novel therapies for these diseases based on an understanding of their pathogenesis. Clinical research is currently directed towards AIDS-related malignancies as well as the underlying HIV infection. Some areas of focus include antiangiogenesis and other targeted approaches for Kaposi's sarcoma; immunologic and vaccine approaches for HIV infection; and novel anti-HIV therapies. Included in the clinical research effort are studies of the neuropsychological aspects of HIV infection in children. Some areas of laboratory focus include Kaposi's sarcoma-associated herpesvirus (KSHV), also called human herpesvirus-8 (HHV-8); studies of HIV drug resistance; the regulation of splicing in human papilloma virus (HPV) and KSHV; interaction between cellular and viral genes; and the effects of hypoxia and redox on KSHV and HIV

Investigators in the branch have previously made substantial contributions to the development of such AIDS therapies as zidovudine (AZT), didanosine (ddI), and zalcitabine (ddC), and paclitaxel for the therapy of Kaposi's sarcoma. Accomplishments during the past several years have included: the identification of interleukin-12 (IL-12) as an active agent for Kaposi's sarcoma; the identification of a novel protease inhibitor and nucleoside analog as anti-HIV agents; conduct of a phase I trial in children on the anti-HIV drug tenofovir; the identification of the transcriptional program of KSHV; the elucidation of gene splicing in key HPV and KSHV genes; and the role of hypoxia inactivating KSHV infection. The branch provides a unique environment in which to conduct translational research on AIDS-related malignancies and HIV. Training opportunities are available for laboratory and clinical research. Members of the branch have collaborations with Dr. Denise Whitby of the Division of Cancer Epidemiology and Genetics; Giovanna Tosato of the Basic Research Laboratory; and a number of other researchers both within and outside the NCI. In addition, members of the branch coordinate their clinical AIDS malignancy with the NCI-sponsored AIDS Malignancies Consortium.
