Title Secretome mediated interactions between sensory neurons and breast cancer cells.
Journal Int J Cancer
Abstract The role of the nervous system in aiding cancer progression and metastasis is an important aspect of cancer pathogenesis. Interaction between cancer cells and neurons in an in vitro platform is a simple and robust method to further understand this phenomenon. In our study, we aimed to examine in vitro reciprocal effect between breast cancer cells and cancer-sensitized peripheral primary sensory neurons. Secretome obtained from either cultured DRG neurons from tumor-burdened rats, or MRMT1 breast cancer cells were used to study neuronal and cancer cell reciprocity. We utilized neurite analysis, modified cell migration assay and cell signaling pathway inhibitors to determine neurite growth patterns and cell migration in PC12/DRG neurons and MRMT1 cells, respectively. MRMT1 secretome was found to induce significant neurite outgrowth in PC12 and primary sensory neurons. Secretome-induced neurite growth in PC12 cells was partly mediated by PI3K and ERK pathways, but not by adenylyl cyclase. Conversely, secretome from tumor-sensitized sensory neuron cultures induced increased rate of migration in cultured MRMT1 cells. Results from our study provide additional support to the hypothesis that both breast cancer cells and nerve terminals secrete signaling messengers that have a reciprocal effect on each other.
