Application

Polyadenylic acid-Polyuridylic acid (polyAU) is a double stranded homodimer studied for potential therapeutic activity, especially when coupled with radiotherapy. PolyA/U is used in comparative physiochemical studies with other duplex and single-stranded polymers such as poly-A and poly-U.

With a median follow-up of 14 years, the combination of polyadenylic-polyuridylic acid plus locoregional radiotherapy (257 patients) has significantly improved disease-free survival (p = 0.03) and significantly reduced the incidence of metastases (p = 0.04) when compared to CMF alone

Many cancer cells express Toll-like receptors (TLR) that offer possible therapeutic targets. Polyadenylic-polyuridylic acid [poly(A:U)] is an agonist of the Toll-like receptor TLR3 that displays anticancer properties. In this study, we illustrate how the immunostimulatory and immunosuppressive effects of this
