Method of screening for antiandrogen agent

摘要

A novel action mechanism wherein androgen receptor (AR) is activated by the interaction between cyclin E and the androgen receptor was revealed. This activation is resistant to existing anti-androgen agents and both androgen receptor ligand-dependent and independent activations were found to participate in this mechanism. Methods of screening for anti-androgen agents using cyclin E are also provided by the present invention. Based on the findings as described above, novel anti-androgen agents can be screened. These anti-androgen agents are expected to be efficacious also against pathological conditions that have become resistant to existing anti-androgen agents. Thus, the instant invention opens up new possibilities for treatment using anti-androgen agents that had their limitations until now.
