Core Tip

Core tip: Altered mucin expression may be correlated with biological behavior and possibly with the prognosis of colorectal carcinoma (CRC). However, many contradictory results make it difficult to interpret its clinical significance, possibly because of CRC variations. Therefore, we examined mucin (MUC)2 and MUC5AC expressions in different pathological CRC subtypes by immunohistochemistry to determine their true clinical significance. Our results suggest that the expression profiles and the clinical significance of these mucin core proteins are different according to histological subtypes. This may reflect different pathogeneses for these tumors.
