Influence of p53 status on CPD removal along the TS and NTS of c-jun and hprt in TK6 and NH32 treated with monochromatic 254 nm-UV. (A) TS and NTS of c-jun using primers JE (nucleotides +100 to +190) and JS (nucleotides +233 to +389) for the TS and primers JT (nucleotides +230 to +310) and JY (nucleotides +1644 to +1820) for the NTS. Each data point represents the mean of 25 sites for the TS and 27 sites for the NTS. (B) TS and NTS of hprt using primers HA (exon 2, nucleotides +14890–+14980) and HC (exon 3, nucleotides +16740 to +16880) for the TS, and primers HB (exon 2, nucleotides +14850 to +14967) and HD (exon 3, nucleotides +16510 to +16630) for NTS. Each data point represents the mean of 38 sites for the TS and 45 sites for the NTS. The standard error of the mean, calculated for each data point, was less than ±3.0% in all cases. Open and filled symbols depict repair of the TS and NTS, respectively. □, ▪ TK6; ▵, ▴ NH32.
