Abstract

The gene MT3-MMP (also known as MMP16) encodes the membrane type 3 matrix metalloproteinase, which is a member of the matrix metalloproteinase (. MMP) gene family. Several MMPs are associated with migration in colorectal cancer (CRC). However, the methylation status of the MT3-MMP promoter in CRC has not been reported. The methylation status and expression levels of MT3-MMP were investigated in primary tumor tissues and adjacent normal tissues in 105 patients with CRC, one normal colon cell line (CCD18Co), and three CRC cell lines (SW480, DLD-1, and LoVo) by quantitative methylation-specific PCR and real-time PCR. MT3-MMP was hypermethylated in 82 of 105 CRC tissues (78%), 30 of 105 adjacent normal tissues (29%), and two of 11 normal colon tissues (18%). MT3-MMP mRNA was significantly reduced in CRC compared with that in adjacent normal tissues (. P<0.05). The methylation-mediated downregulation of MT3-MMP was restored by treatment with 5-aza-2'-deoxycytidine in two CRC cell lines, and MT3-MMP promoter activity was significantly reduced by methylation. The knockdown of MT3-MMP induced cell migration, but overexpressed MT3-MMP reduced cell migration in CRC cells. These results demonstrate that the MT3-MMP promoter is frequently hypermethylated in CRC and that downregulation of MT3-MMP may be important for cell migration in CRC.
