FIG. 4.
Inhibition of TLR2 and TLR4 receptors using siRNA ameliorates high-glucose–induced NF-κB p65-dependent DNA binding activity in the nuclear extracts of THP-1 cells by ELISA as described in research design and methods. Values are normalized to milligrams nuclear protein and expressed as means ± SD. *P < 0.05 vs. Sc + high glucose (HG); Sc, scramble control siRNA; TLR2si, TLR2 receptor siRNA; TLR4si, TLR4 receptor siRNA. n = 4 experiments in duplicate. □, Mannitol; , LG (5.5 mmol/l); ▪, HG (15 mmol/l).
