Calcineurin selectively activates IL-1α expression. Porcine aortic endothelial cells were transfected with increasing amounts of a plasmid encoding constitutively-active calcineurin (ΔCaM-AI). Control cells were stimulated with IL-1α. After 12 hours the amounts of IL-1α, Eselectin and GAPDH mRNA were measured by RT-PCR. The results show that calcineurin activity selectively activates IL-1α expression.
