keratin - (pronounced) (KAYR-uh-Tin) A type of protein found on epithelial cells that line the inside and outside surfaces of the body. Keratins help form the tissues of hair, nails, and the outer layer of skin. They are also found on cells in the lining of organs, glands, and other parts of the body. Certain keratins can be found in higher than normal amounts in patients with various types of epithelial cell cancer, including lung, breast, colon, bladder, and head and neck cancer. Measuring the amount of certain keratins in the blood can help plan cancer treatment, find out how well the treatment is working, or if the cancer has come back. A keratin is a type of tumor marker. Also called cytokeratin
