APEX1 and colorectal carcinoma: Inflammation and apoptosis induced by DSS could also be proved to be improved by the decreased amounts of the following proteins: inflammatory degree-related proteins, i.e., haptoglobin (Hpt), complement component 3 (Co3), myeloperoxidase (Perm), Annexin A2 (Anxa2), and heat shock protein family A member 4 (Hsp74); proteins involved in apoptosis, i.e., keratin 20 (K1c20), apyrimidinic endodeoxyribonuclease 1 (Apex1), caspase-7 (Casp7), and caspase-3 (Casp3); and a protein of biomarker for colorectal carcinoma, heterogeneous nuclear ribonucleoprotein U (Hnrpu) (Table 2).
