Multiple alignment of HPV-16 E7 protein sequences determined from tumor DNA sequencing. HPV-16 E7 DNA sequences were PCR-amplified from total tumor DNA and sequenced. DNA sequences were translated to and protein sequences aligned for comparison. Two HPV-16 E7 sequence variants are present in the analyzed tumor samples: N29 in KTS2, KTS3, and KTS6 marked as red, and S29 in the remaining samples. The E7 11–19 YMLDLQPET T-cell epitope highlighted as yellow was conserved in all samples. Results are representative of two independent sequencing reactions performed on nine different tumor DNA samples.
