ENO2 and neoplasm: Tumor formation was evidenced visually on B(a)P model group II, hence the tumor markers CEA and NSE were also shown to be elevated in group II by 438% and 389% respectively compared to the normal control group I. The levels of CEA and NSE were reduced significantly by matricin treatment in group III by 66% and 52% respectively compared to B(a)P model group II (Fig. 5).
