Effects of IL-1β and epinephrine on NF-κB translocation in HMC-1. HMC-1 were treated for 1 and 2 hours with IL-1β and epinephrine. NF-κB translocation was analyzed by a shift in oligonucleotide binding in EMSA gels. After one hour of treatment, NF-κB translocation is increased in the IL-1β treated cells but not in the untreated or epinephrine treated cells. Addition of IL-1β plus epinephrine does not further enhance NF-κB translocation. After two hours of treatment, NF-κB translocation in HMC-1 starts to decrease.
