OXT and glioma: Oxytocin can inhibit proliferation of neoplastic cells of other epithelial origin, e.g. in the ovary,[29] endometrium,[30] prostate,[31] bone[32], breast,[33] and in neuroblastoma and glial tumours.[34] Oxytocin can increase the intracellular concentration of cAMP resulting in decreased proliferation, a mechanism that might be relevant for the association with BO in the present study, but further research is needed.
