1,5-isoquinolinediol leads to an increase up to 8-fold in the absolute frequency of gene targeting in the correction of the mutation at the stable integrated HSV tk gene.
1,5-Isoquinolinediol is a potent PARP antagonist and decreases cleaved PARP in diabetic retina. 1,5-Isoquinolinediol (500 μM H2O2; 24 hours) attenuates H2O2-induced upregulation of cleaved PARP-1 expression in retinal Muller cells. 1,5-Isoquinolinediol attenuates diabetes-induced upregulation of retinal nitrated protein expression. 1,5-Isoquinolinediol attenuates diabetes-induced activation of NADPH oxidase in the retina.
