Effect of cholesterol reducing agents on cell viability and cholesterol level. A549 cells were treated with Gem 400 μM and/or Lov 40 μM for 24 or 48 h. (A) Cell viability was compared to untreated cells as measured by trypan blue cell viability assay (n=3). (B) Cellular cholesterol levels were determined by Amplex Red Cholesterol assay. Data were normalized to protein levels as determined by bicinchoninic acid assay (n=3). Gem: gemfibrozil, Lov: lovastatin. *; P<0.05, **; P<0.01 (Student t-test).
