Molecular Crosstalk: Bone Metastatic Prostate Cancer and Nociceptive Neurons

Abstract

The goal of this project is to determine the roles of angiotensin II and its receptor in prostate cancer induced bone pain and bone metastatic growth. Aim 1 will provide the framework to identify the extent to which the interaction between cancer cells and nociceptive neurons through the angiotensin II and receptor axis affects cancer-induced bone pain. Aim 2 will determine the downstream molecular mechanisms whereby angiotensin II and its receptor axis affects bone pain. Aim 3 will define how nociceptive neuron influence tumor outgrowth. We believe that the insights derived from our investigations will lead to new strategies for reducing cancer-induced bone pain and also the outgrowth of bone metastasis. During this period, we developed a syngeneic murine prostate cancer (PCa)-induced bone pain model which allows us to further elucidate the roles of the crosstalk between bone metastatic PCa and sensory neurons in both bone metastatic progression and its resultant bone pain in an immunocompetent setting. We developed an in vitro primary sensory neuron culture system to investigate the more detailed mechanism of the cancer/nerve interaction, and a semi-automated quantification method to measure the in vitro neurite outgrowth of these primary sensory neurons.
