Interleukin-1 induces rapid and transient expression of the c-fos proto-oncogene in isolated pancreatic islets and in purified beta-cells.

Abstract

The effect of interleukin-1 beta (IL-1) on expression of c-fos mRNA in isolated rat pancreatic islets was examined. Accumulation of c-fos mRNA was demonstrable after 30 min of exposure to IL-1, peaked by 60 min, and declined thereafter. Fluorescence-activated cell sorting (FACS) of dispersed islet cells was employed to localize the accumulation of c-fos mRNA to the beta-cell. Cycloheximide did not influence the induction of c fos mRNA by IL-1. Accumulation of c-fos mRNA therefore appears to be an early signal transduction event in the beta-cell and a component of the cellular mechanism(s) by which IL-1 influences beta-cell function.
