Washington: Findings from a new study have suggested that beta-blockers, which are used for the treatment of high blood pressure and block the effects of stress hormone adrenaline, could increase the efficacy of anti-cancer therapies.Prostate cancer patients have increased levels of stress and anxiety; however, several recent studies have found that men who take drugs that interfere with the stress hormone adrenaline have a lower incidence of prostate cancer.George Kulik and colleagues at Wake Forest University examined the relationship between stress and cancer progression in a mouse model of prostate cancer.Kulik and colleagues found that mice that had been subjected to stress (exposed to the scent of a predator) exhibited a significantly reduced response to a drug that induces cancer cell death compared to their unstressed counterparts.
