Molecules involved in cell survival. Flow cytometry analyses of a Bclx_L, b Bax, c caspase-9, d caspase-3, and e survivin 48 h in control and UVB-exposed cells. The results obtained are the mean of three independent experiments ± S.D; for each molecule, a representative experiment is shown (right panels). Student’s t test indicates (*) p < 0.05 MVSMC (controls vs 48-h UVB); (°) p < 0.05 FVSMC (controls vs 48-h UVB); (**) p < 0.01 MVSMC (controls vs 48-h UVB); (°°) p < 0.01 FVSMC (controls vs 48-h UVB); (§) p < 0.05 MVSMC vs FVSMC; (§§) p < 0.01 MVSMC vs FVSMC
