The adapting ability of living organisms is the key to survival of the species, and its scope is defined by homeostasis, meaning the tendency of any living system to maintain its biologic parameters. Heat shock proteins are part of a homeostasis system in charge with the regulation of damaged proteins caused by the action of several types of stressors. Among all types of stressors, the electromagnetic radiation has not yet been investigated in terms of heat shock protein response. Recent investigations regarding in vivo experiments using electromagnetic exposure from laboratory sources and commercial mobile phones indicate that the biologic response is more intense when using real life sources. This paper proposes a model for heat shock proteins expression as response to electromagnetic radiation exposure, based on a Hill controller.
