  • Publication number: 20040014144
    Abstract: In a method of identifying substances acting as inhibitors of NF-&kgr;B activation by MSK1 or MSK2, MSK1 or MSK2 are contacted with a predetermined amount of one or more test substances in the presence of an NF-&kgr;B subunit or a complex of NF-&kgr;B subunits, and a test substance is identified as an inhibitor of NF-&kgr;B activation by determining a decrease in NF-&kgr;B activation by MSK1 or MSK2 in the presence of said test substance compared to the level of NF-&kgr;B activation in the absence of said test substance.
