Estrogen is a powerful mitogen ?an agent that causes cells to divide, and too much estrogen can cause cells to divide too quickly. While many women with estrogen-dependent breast cancer take aromatase i...Macrophage signaling may affect hormone resistance in prostate tumors

Male hormones called androgens are essential for the physiological function and growth of the prostate gland, and anti-androgen treatment, which blocks the expression of androgen target genes, is widely used for the treatment of prostate cancer.
