ABSTRACT:
The present invention provides synthetic ribozyme oligonucleotides alone and within constructs. The ribozyme gene provides methods for the treatment of prostate hyperplasia and other androgen dependent pathologies. Improved therapies for such diseases are provided without significant hormonal imbalance and without surgical intervention. Also provided are techniques for selecting and synthesizing effective and specifically targeted molecular tools for use in inhibiting androgen receptor gene expression.
