1. A method of determining if a test compound is able to modulate the interaction between androgen receptor and β
- -catenin comprising the steps of;
(a) providing a cell comprising;
(i) a DNA sequence encoding a hybrid protein comprising a DNA binding domain fused to the NH3-terminal region of β
-catenin, (ii) a DNA sequence comprising an upstream activation sequence corresponding to said DNA binding domain operably linked to and controlling transcription of a reporter gene, and (iii) a DNA sequence encoding androgen receptor protein, (b) introducing the test compound to the cell, optionally in the presence of androgen; and
(c) measuring the expression of the reporter gene, wherein an increase or decrease of expression by the reporter gene indicates that the test molecule is able to modulate the interaction between androgen receptor and β
-catenin.

Abstract
Methods for determining if test compounds are able to modulate the interaction between androgen receptor and β-catenin are disclosed. Methods for the determining whether a test compound selectively modulates an androgen receptor signaling pathway over a β-catenin-Wnt signaling pathway or a β-catenin-Wnt signaling pathway over an androgen receptor signaling pathway are also disclosed.

23. A method of determining if a test compound selectively modulates the β
- -catenin-Wnt signaling pathway over an androgen receptor signaling pathway comprising;
(a) identifying a test compound which increases or decreases the expression of a gene by inhibiting the AR mediated interaction with β
-catenin, wherein the test compound removes androgen-liganded AR repression on Wnt signaling without repressing androgen-AR mediated transcription; and
(b) assaying the test compound of (a) to determine whether the test compound increases or decreases the expression of a gene through a β
-catenin independent androgen receptor signaling pathway;
whereby the test compound of (a) selectively modulates the β
-catenin-Wnt signaling pathway by inhibiting the ability androgen-liganded AR to interact with β
-catenin if the test compound fails to increase or decrease the expression of a gene through an androgen receptor signaling pathway. - View Dependent Claims (24, 25)

26. A method of determining if a test compound selectively modulates an androgen receptor signaling pathway over a β
- -catenin-Wnt signaling pathway comprising;
(a) identifying a test compound which increases or decreases the expression of a gene through an androgen receptor signaling pathway; and
(b) assaying the test compound of (a) to determine whether the test compound increases or decreases the ability of androgen-liganded AR or non-liganded AR to inhibit β
-catenin/Wnt signaling;
whereby the test compound of (a) selectively modulates an androgen receptor signaling pathway without removing androgen-liganded AR repression of Wnt signaling or does not promote the interaction between AR and β
-catenin in the absence of an AR agonist resulting in the test compound having no activity in increasing or decreasing the expression of a gene regulated by β
-catenin-Wnt signaling pathway. - View Dependent Claims (27, 28)
