From: The mode of lymphoblastoid cell death in response to gas phase cigarette smoke is dose-dependent
Cytotoxicity of GPS-exposed cells increases in a dose- and time-dependent manner. Cytotoxicity was measured in terms of LDH release in the culture medium from cells exposed to 1, 3 or 5 puffs at 1, 4 and 24 hours post-exposure. The graph incorporates mean values ± SD of data derived from one representative experiment of three independent series performed in quintuplets. * P < 0.05 compared with control, ** P < 0.0001 compared with control (one-way ANOVA).
