Figure Lengend Snippet: Effects of ethanolic yacon leaf extract (YLE) on lipopolysaccharide (LPS)-induced BV2 microglial cell viability and the production of nitric oxide (NO). (A) BV2 cells were treated with YLE (10, 25, and 50 μg/mL) for 48 h and cell viability was examined using 2,3-bis [2-methyloxy-4-nitro-5-sulfophenyl]-2H-tetrazolim-5-carboxanilide (n = 4). Cell viability in the quiescent state is expressed as 100%. (B) Cells were co-treated with YLE and LPS (500 ng/mL) for 48 h. The production of NO in BV2 cells was determined using the Griess reagent (n = 6). Data are expressed as means ± SE. Values with the same letter are not significantly dfiferent, as determined byT ukey’s multiple range test (p < 0.05).

Figure Lengend Snippet: Effects of ethanolic yacon leaf extract (YLE) on lipopolysaccharide (LPS)-induced mRNA expression of proinflammatory cytokines in BV2 cells. BV2 cells (2 × 105 cells) were seeded in 100 mm dishes for 24. Thhe cells were then incubated in the absence or presence of LPS (500 ng/mL) anYd LE (50 μg/mL) for 24 h. mRNA levels of inducible nitric oxide synthase (iNOS), cyclooxygensae (COX)-2, interleukin (IL)-1β, and tumor necrosis factor (TNF)-α were assessed by the real-time polymerase chain reaction. (A–D) Relative mRNA expression compared with the LPS-treated group (100%). Data are expressed as means ± SE (n = 3). *Significant difference compared with LPS-only treatment (p < 0.05).
