p63 gene expression.

<p>(A) Primary keratinocytes analysed for p63 gene expression in the α6 integrin^high+/CD44⁺ and remainder populations using QRT-PCR. Data represents the log mean fold change of the α6 integrin^high+/CD44⁺ population from the remainder population ± SEM of three replicates, normalised against GAPDH housekeeping gene. Keratinocytes analysed for gene expression after cisplatin (B) or UVB (C) where data represents the log mean fold change from the control (vehicle-only) ± SEM of three replicates, normalised against 28S-r-RNA housekeeping gene. Statistical significance was determined using the paired Student’s t-test, *P<0.05.
