英文摘要
Breast cancer is a complex disease requiring multidimensional approaches
to elucidate causative processes. Our overall goal is to define molecular
and cellular mechanisms important in mammary tumorigenesis, utilizing the
BALB/c mouse model and known etiologic factors, virus (MMTV) and chemical
carcinogen (DMBA). This system provides an unparalleled opportunity to
assess molecular changes underlying discrete stages of breast
carcinogenesis. Our hypothesis is that the MMTV long terminal repeat
(LTR) superantigen gene product [pORF(sag)] is multifunctional in the
viral life cycle and in mammary tumorigenesis.
Specific aims are the following: (1) To characterize LTR pORFsag)
expressed in murine cells. (2) To identify LTR pORF interactive cellular
proteins using the yeast two-hybrid system. (3) To investigate the role of
mammary oncogenes in DMBA-induced mammary tumorigenesis.
Identification and functional analysis of pORF(sag) interactive cellular
proteins will reveal regulatory processes important in mammary cell growth
and development. This analysis will also provide basic information about
the prototype viral superantigen [pORF(sag)]. This program builds on our
experience with the mammary tumor system, viral oncoprotein-cell
regulatory protein interactions, and endogenous MMTV expression in normal
and DMBA-transformed mammary cells.
