Our lab is studying the molecular biology and pathogenesis of
These viruses have been important models for studying gene
expression and cancer.
HIV-1, the causative agent of AIDS, is also a
retrovirus. Historically, we have worked on
Moloney murine leukemia
virus (M-MuLV). Current M-MuLV projects include using enhancer variants
of M-MuLV to study the complex (and multi-step) process of leukemogenesis
in mice, and using M-MuLV
as a system to study cellular chromatin and
chromatin-associated proteins. A second project involves
the use of
MuLV-based retroviral vectors to over-express normal cell proto-oncogenes
in cultured cells.
Proto-oncogene over-expression occurs in some
spontaneous cancers, and we have shown that vectored over-expression
cultured cells increases their sensitivity to transformation by chemical
The molecular mechanisms involved in this are under
investigation. A third project involves
studies of the transactivating
proteins of human T-cell leukemia virus HTLV-I, which causes
leukemia and HIV-1, which causes AIDS. The transactivating proteins
and tat respectively) cause high level expression of the viruses in
infected cells, but they
have different mechanisms of action. We are
investigating the mechanisms of action for both tax and tat.
resulting information might eventually lead to new antiviral compounds.
