title: Photo-regulation of DNA/RNA duplex formation by azobenzene-tethered DNA towards antisense strategy.
abstract: Modified DNA carrying an azobenzene was successfully applied to the photo-regulation of DNA/RNA hybridization. When the azobenzene was isomerized from trans- to cis-form on UV-irradiation, the melting temperature of the duplex was significantly lowered. This process was totally reversible so that the Tm increased by cis-->trans isomerization induced by visible light irradiation.
