Correlations of partial and extensive methylation at the p14ARF locus with reduced mRNA expression in colorectal cancer cell lines and clinicopathological features in primary tumors

Abstract excerpt

p14(ARF) is a putative tumor suppressor gene thought to modify the levels of p53. CpG sites within the 5'-flanking region and exon 1beta of p14(ARF) are targets of aberrant methylation and transcriptional silencing in human colorectal cancer (CRC). Here we have developed methylation-specific polymerase chain reaction (MSPCR) methods to detect methylation of CpG sites in p14(ARF) in CRC cell lines and primary CRC...
