Compared to vehicle-treated mice, male mice in the 25-week UVB exposure model treated topically with C E Ferulic did not exhibit a significant alteration in tumor number (Figures 1(a) and 3(a) ) but displayed a 60% increase in tumor burden compared to vehicle-treated mice, which possibly due to the variability in this outbred mouse strain did not reach statistical significance ( P = 0.5590, Figures 1(b) and 3(b) ).
