Ovarian cancer cells use stress hormone signaling to shut down immune system, research reveals

When activated in ovarian cancer cells, the receptor for the body's primary stress hormone alters the tumor environment in ways that blunt immune response, according to new research led by UT Southwestern Medical Center. The findings, published in Endocrinology, identify a previously unrecognized role for the glucocorticoid receptor (GR) in shaping the ovarian cancer tumor microenvironment.
