Silencing of TGF-beta receptor type II expression by sIRNA

摘要

The present application is directed to siRNA-based silencing of the type II receptor of TGF. siRNAs that target this receptor abrogate the receptor protein and transcript, TGF-mediated processes such as fibronectin assembly and cell migration also are inhibited and the molecules of the invention are efficacious in reducing the inflammatory response and matrix deposition. These findings show that siRNAs can be successfully delivered both in vitro and in vivo to regulate the TGF type II receptor level and modulate wound response. Methods and compositions exploiting the findings of the present invention have a wide-ranging application, extending from treatment of disorders of the eye to other organs and tissues throughout the body.
