Figure 6. Analysis of BER and SSB repair protein levels in HPV-negative and HPV-positive OPSCC cells.

Figure 6

(A) Whole cell extracts from OPSCC cells were prepared and analysed by 10 % SDS-PAGE and immunoblotting with the indicated antibodies. (B) Levels of BER and SSB repair proteins relative to actin were quantified from at least three independent experiments. Shown is the mean protein level relative to actin with standard errors from at least three independent experiments, normalised to those calculated in the HPV-negative UMSCC6 cell extracts which was set to 100 %. *p < 0.05, **p < 0.01, ***p < 0.001 as analysed by a one sample t-test of normalised protein levels in the respective cell extracts relative to the UMSCC6 extracts.
