OAZ2 and colorectal cancer: To evaluate the biological role of Ornithine Decarboxylase Antizyme 2 (OAZ2) in colorectal cancer cell dynamics, quantitative real-time PCR (qRT-PCR) analysis revealed that OAZ2 mRNA levels are higher in normal tissues compared to colorectal adenocarcinoma (COAD) tissues (Fig. 8A).
