Steroids, thyroid hormones and derivatives of vitamin A are small liposoluble molecules that regulate development, differentiation and physiological response to diverse stimuli and are essential to the survival of the individual. Natural and synthetic analogs of these substances are used extensively to control a broad spectrum of human diseases including cancer. The effects of each hormone depend primarily on a protein referred to as a receptor. The study of these receptors is important to understand the molecular mechanisms involved in the cellular response to these inducers.
