a, hVegfa siRNA and Vegfr1 siRNA suppressed CNV in Tlr3+/+ but not Tlr3−/− mice. b, Vegfr1-siRNA–chol suppressed CNV in Tlr3+/+ but not Tlr3−/− mice. n = 5–6. c, hVegfa siRNA and Vegfr1 siRNA, whose anti-sense (as) strands were modified with 5′-methoxy (CH3O) substitution, preventing incorporation into RISC, suppressed CNV in Tlr3+/+ but not Tlr3−/− mice. n = 9–14. d, siRNAs targeting mouse (m) or human (h) Vegfa reduced CNV in Tlr3+/+ but not in Tlr3−/− mice. mVegfa-siRNA–chol and hVegfa-siRNA–chol suppressed CNV in Tlr3+/+ mice; however, mVegfa-siRNA–chol but not hVegfa-siRNA–chol suppressed CNV in Tlr3−/− mice. n = 8–10. siRNAs were at 1 μg; asterisk, P < 0.05 compared to vehicle (siRNA buffer).
