Glucocorticoid receptors (GR), also known as NR3C1 (nuclear receptor subfamily 3, group C, member 1), are a type of steroid hormone receptor that mediates the effects of glucocorticoids, which are steroid hormones involved in various physiological processes, including metabolism, immune response, and stress response.
In certain cancer subtypes such as gynaecological cancers (endometrial and ovarian) and early stage, untreated triple negative breast cancers, high GR expression is linked with cancer progression and therefore a poorer patient prognosis.
Glucocorticoid receptors play a significant role in various cancers, and their expression can have complex prognostic implications. In some cancer types, high GR expression is associated with better outcomes, while in others, it may correlate with aggressive disease and treatment resistance. The relationship between glucocorticoid receptor expression and cancer prognosis can vary depending on the specific cancer type, stage, and other molecular factors.
