The changes of every detection indicator with different UVB doses for different durations. a, cell proliferation inhibition rate, CPIR; b, apoptosis rate; c, β-catenin mRNA expression; d, SMP30 mRNA expression.
The changes of HSF apoptosis with different UVB doses for different durations. A, different doses UVB treatment 1 day; B, different doses UVB treatment 2 day; C, different doses UVB treatment 3 day.
Analysis of the relationship between every detection indicator and different UVB doses for different durations by Bilinear regression. a, cell proliferation inhibition rate (CPIR); b, apoptosis rate; c, β-catenin; d, SMP30), P<0.05.
