A comparison of BER activity in the lymphocytes and tissue of CRC patients and healthy controls. Each electropherogram shows two fractions of DNA: 450 pb repaired and 185 pb unrepaired. Lanes 1-2 indicate lymphocyte BER efficiency while lanes 3-4 refer to BER in tissue. Samples are presented in the following order: K: positive control; DNA substrate did not contain uracil and so reflects 100% of repair; 1: healthy control; 2: colorectal cancer; 3: unchanged colon tissue; 4: colorectal cancer.
