Abstract

The c-myc protein, a basic leucine zipper helix-loop-helix transcription factor is a key regulator of life and death [1–4]. c-myc expression is coupled to a multitude of physiological processes and has been reported to be regulated by a long list of hormones, cytokines, lymphokines, nutritional status, development and differentiation. Myc levels can be pharmacologically perturbed, at least transiently, by a host of agents. Consistent with the notion that c-myc expression is tightly regulated, both the mRNA and protein products of this gene are extraordinairily short-lived, 30 minutes and 20 minutes, respectively [1–4]. In growing cells wide-ranging excursions in c-myc expression are generally not seen, attesting either to tight homeostatic regulation or constitutive expression of c-myc.
