From: Influence of chlorpyrifos exposure on UVB irradiation induced toxicity in human skin cells
Caspase-3/7 activity measured after exposure of HaCaT cells (A) and BJ cells (B) to CPS and/or UVB radiation. a denotes statistically significant difference of means from control (cells not treated with CPS nor UVB), b denotes statistically significant difference between CPS and UVB treated cells, as compared to UVB treatment alone, the two-way ANOVA and post-hoc comparison by Bonferroni test, P < 0.05. Mean ± SD, (n = 3), CPS, chlorpyrifos
