In
vivo validation of cp-asiAR KD efficacy. cp-asiAR
was intradermally injected into the dorsal skin of mice, and the mRNA
(A) or protein (B) level of AR in the injection site was measured
after 24 h (n = 3). Protein level was quantitated
using image analysis of western blotting (B, inset). RPL32 and β-actin
were used as references for the relative mRNA and protein levels of
AR, respectively. (C) cp-asiAR was injected at three doses, and skin
biopsy was performed at the indicated times after injection. AR protein
level normalized by β-actin was measured in the biopsy tissue.
AR protein levels relative to the vehicle control are shown with the
standard deviations (n = 4). Statistical significance
was calculated using the t-test with the vehicle
control (VC) (*, p < 0.05; **, p < 0.01; ***, p < 0.001).
