SMO expression in colorectal cancer may interact with tumor CIMP status to affect patient prognosis, although confirmation by future studies is needed.
Moreover, RT-PCR and Western blotting analysis demonstrated that there was no significant difference in SMO mRNA expression between the corresponding CRCs and nontumorous tissues, whereas SMO protein markedly increased in CRCs (P < 0.01).
The construction of the lentiviral vector pLV-THM-miR-338-3p-inhibitor with specific secondary structure provides a basis for further studies the molecular function of miR-338-3p in colorectal carcinoma. miR-338-3p may suppress SMO gene expression and thereby inhibit colorectal carcinoma migration.
To investigate the expression of three components of the Hedgehog (Hh) signaling pathway (SHH, SMO and GLI1) in human colorectal cancer (CRC) tissues and evaluate their association with clinicopathologic characteristics of the patients.
