EV-LPS increase antioxidant marker gene expression in smooth muscle cells. MOVAS-1 cells were incubated with EVs-derived RAW cells for 24 h. Gene expression of (A) SOD-1, (B) SOD-2, (C) Nrf2, and (D) Keap1 was then quantified by quantitative real-time PCR and normalized to that of the housekeeping gene ß-actin. Data are expressed as the mean ± SEM of four independent experiments performed in triplicate (n = 4). *p < 0.05 vs. CT, $p < 0.05 vs. EV-CT, Mann-Whitney test. EV-CT: EV-derived from untreated macrophages, EV-LPS: EV-derived from LPS-EK-treated macrophages.
