Gene involved in sense of smell could play a role in the spread of breast cancer to the brain
An olfactory receptor typically associated with the sense of smell may also trigger breast cancer cells to metastasize through a signaling pathway to the brain, bones and lung. Future research could potentially lead to an inhibitor of OR5B21 to prevent cellular invasion and metastasis, thus prolonging the lives of breast cancer patients.
