Assessing hormonal effects of compounds, useful in testing drugs, from effect on interaction of nuclear receptor and co-modulator, also diagnosing diseases caused by improper co-modulation
Testing the hormonal effects, especially (anti)androgenic effects, of substances (A) comprising transfecting cells with two vectors, one contains DNA for a nuclear receptor protein (I), or its fragment, the other DNA for a co-modulator (II), is new. The transcriptional activity of (I) in presence of (II) and/or the influence of (A) on the interaction between (I) and (II) is measured through protein-protein or protein-protein-DNA interactions. Independent claims are also included for the following: (1) detecting disorders of regulation in the co-modulatory mechanism between androgen receptor (AR) and the co-modulator ARAP11 by measuring the concentration of ARAP11 and/or AR, or their fragments; (2) ARAP11 or its fragments with co-modulatory properties on AR; and (3) DNA encoding ARAP11, or its fragments, and sequences that hybridize to the DNA.
