Abstract
Abstract Cancers are known to be heterogeneous diseases. Tumor cell proliferation and the development of metastatic disease involve the activation of multiple, sometime parallel and often compensatory signal transduction pathways. We have developed a cell-based assay platform that measures specific kinase activity within cells, thus allowing us to conduct pathway-based analyses. This platform can be used for 1) discovering new biomarkers and 2) guiding the design of new therapeutic strategies in personalzed medicine, specifically tailored to the patient's genotype. In the present study, we have used this platform to study the impact of G-protein coupled receptor (GPCR) mediation on IGF-1r (RTK) signal transduction cascades in the presence/absence of oestradiol (ER) using MCF-7 breast cancer cells. The results of these studies indicate that mediating neuroendocrine pathways may be an alternative approach that could enhance the efficacies of specific target therapeutics for the treatment of breast cancer.
