G-Rg6 regulates ROS and exhibits antioxidant effects. (A) HPDL cells were seeded in a 6-well plate at 5 × 10³ cells/mL. Natural products derived from ginseng at the indicated concentration were treated with PG-LPS and incubated for 2 h. And then ROS levels were measured by DCF-DA. (B) The expression of SOD and CAT proteins was measured by Western blot analysis from cells pretreated with G-Rg6 and stimulated by PG-LPS. The results were normalized to β-actin expression. * p < 0.05, versus the only PG-LPS-treated group.
