Effects of several concentrations of inhibitors, filipin III (a), β-cyclodextrin (b), and chlorpromazine (c), on internalization of siRNA with/without INT and mTat/PEI/INT in HSC-3 cells. β-actin mRNA was measured by QRT-PCR and then % remaining β-actin mRNA expression was calculated based on control as 100%. *p < 0.05 and **p < 0.01
