Several antiandrogens show agonistic properties for a mutated androgen receptor ( LNCaP cell variant ); trypsin digestion of antiandrogen -bound mutated receptor also resulted in a 29-kDa fragment .
 ( protein: trypsin, None) , ( protein: antiandrogen -bound mutated receptor, None) , ( cell line: LNCaP cell variant, None) , ( protein: 29-kDa fragment, None) , ( protein: mutated androgen receptor, None)
