The discovery that c-fos, a proto-oncogene, has a role in pain, has triggered extensive research on the consequences of c-fos expression. It has been shown that c-fos, through its protein form, FOS, leads to expression of dynorphin gene and subsequently dynorphin protein which is implicated in the development of a pain state. This mini review looks at the properties of c-fos and the consequences of its expression following noxious (painful) stimulation.
