OxPLs stimulate the expression of inflammatory cytokines and chemoattractant proteins in cultured ARPE19 cells.

Gene expression as assayed by quantitative PCR on RNA from ARPE19 treated with 50 μg/mL of native-LDL or oxLDL for 12 (A), 24 (B) and 48 (C) hours. Relative mRNA levels of indicated genes (x axis) were calculated by normalizing results with GAPDH and are expressed relative to untreated samples. n = 4. Data are shown as mean ± SEM. *P < 0.05; **P < 0.01.
