Effects of the nucleosides on CSE-induced TNF-α, IL-6, and IL-1β expression in RAW264.7 cells.

Notes: The nucleosides suppressed CSE-induced expression of (A) TNF-α, (B) IL-6, and (C) IL-1β, and (D) their mRNA expression in RAW264.7 cells. *P<0.05, **P<0.01, ***P<0.001, CSE-induced group vs control group (without any treatment); #P<0.05, ##P<0.01, nucleoside treatment groups (25 and 50 µg/mL) vs CSE-induced group. All the experiments were repeated three times. Data shown as mean ± SEM (n=3).

Abbreviations: CSE, cigarette smoke extract; IL-1β, interleukin-1β; IL-6, interleukin-6; TNF-α, tumor necrosis factor-α.
