Stress can have a significant negative effect on health, but our understanding of how stress impacts the development and progression of cancer is just beginning. A team from Roswell Park Comprehensive Cancer Center has identified an important mechanism by which chronic stress weakens immunity and promotes tumor growth. Their findings, just published in Cell Reports, point to the beta-adrenergic receptor (β-AR) as a driver of immune suppression and cancer growth in response to stress, opening the possibility of targeting this receptor in cancer therapy and prevention.
It’s common for people with psoriasis to develop dry, inflamed skin lesions. But researchers found specific gene expression changes in healthy-appearing skin were a better predictor of clinical response to etanercept, an anti-TNF treatment prescribed to up to one-fifth of psoriasis patients. They say finding predictive signs in a patient’s genetic profile is a step toward applying precision medicine to complex inflammatory skin diseases.
