Effect of rs10817938 polymorphism on XPA promoter activity; Schematic representation of reporter plasmids containing a T or C allele at rs10817938, which was inserted upstream of the luciferase reporter gene in the pGL3 Basic plasmid.

<p>pRL-SV40 were co-transfected into SCC-4, SCC-9, SCC-25, HeLa cells as an internal control of <i>Renilla luciferase</i>. Columns are means from three independent experiments and bars are standard deviations.
