ΔNp63α and ERK3 are highly expressed in NMSC. a Representative images of FFPE human skin tissue microarrays were co-immunostained for ΔNp63α and ERK3 in normal skin, AK, SCC and BCC (scale bar = 50 μm). Quantitation of ΔNp63α and ERK3 levels from 53 normal skin samples, 66 AK, 59 SCC and 57 BCC samples are plotted. Y-axis represents the mean fluorescent intensity. Bar plots showing least squares means + SE for ΔNp63α (b) and ERK3 (c). Significance differences indicated at P-value < 0.05 (*) and P-value < 0.01(**) in comparison with normal skin by Student’s t-test
