PARP1 and carcinoma: The amount of OGG1 protein was also higher in carcinoma and adenoma tissues than in normal colon (5.60, range 4.0–7.60 in carcinoma versus 2.50, range 1.60–4.0 in normal colon, p<0.00001, and 7.80, range 6.10–9.30 in adenoma tissue versus 2.29, range 1.25–5.20 in normal colon) although these differences were not as big as for PARP-1.
