Understanding the Science Behind Steroids: How They Work in the Body
Effects of steroids on human physiology are complex lipophilic molecules that exert diverse actions in the body to regulate cellular, tissue, and organ functions throughout life. Steroid hormones, such as cortisol, aldosterone, estradiol, and testosterone, are synthesized from cholesterol in specialized endocrine cells in the adrenal glands, ovaries, and testes, and are released into the bloodstream when needed. Steroid hormones circulate freely within cells to activate intracellular nuclear receptors that function as ligand-gated multidomain transcriptional regulators in the cell nucleus.
Activated nuclear receptors alter the expression of hundreds, if not thousands, of specific target genes in the genome. Steroid hormones influence fetal development, particularly in the respiratory, cerebral, and cardiovascular systems. Betamethasone, a synthetic glucocorticoid, is used prenatally to reduce complications associated with prematurity. The development of new selective partial glucocorticoid receptor agonists may provide better therapies to treat respiratory complications of preterm birth and avoid the harmful effects of postnatal glucocorticoids on other organs.
