Heat maps depicting color-coded NSAIDs-induced differential gene expression patterns of (A) cell cycle, (B) DNA damage, (C) DNA repair, (D) apoptosis and (E) DNA binding categories in CASMC (lanes 1–6) and HCAEC (lanes 7–12). Lanes 1&7: 10 μmol/L CXB, lanes 2&8: 40 μmol/L CXB; lanes 3&9: 10 μmol/L NS, lanes 4&10: 100 μmol/L NS, lanes 5&11: 0.1mmol/L IBU and lanes 6&12: 1.5mmol/L IBU. Yellow to red indicates up-regulated genes and blue indicates down-regulated genes.
