Abstract : The implications for determining whether wnt-5a and wnt-4 act as mediators of normal cell growth are relevant to the detection, diagnosis, and treatment of breast cancer. The intent of this proposal has been to develop new mammary epithelial cell lines which stably express antisense wnt-5a or wnt-4 in order to determine whether the loss of endogenous gene expression of either is important for cell transformation to occur. It was found that disruption of wnt-5a leads to cell transformation and ectopic wnt-5a gene expression in transformed cells reverts cells to a more differentiated phenotype.
