“…[16][17][18] Furthermore, there is a growing body of evidence showing that abnormal methylation of DNA can be an early event in carcinogenesis and can serve as an early cancer detection biomarker, 15 including in EAC. [17][18][19][20] Hypermethylation of CDH13 has been described in many human cancers, 8,14,[21][22][23][24][25][26][27][28][29] including ESCC 24,29 ; however, hypermethylation of CDH13 in precancerous lesions such as Barrett's metaplasia (BE), as well as in BE-associated EAC, is an area that still remains to be explored. We investigated hypermethylation of the CDH13 promoter by real-time quantitative methylation-specific PCR (qMSP) in 259 endoscopic esophageal biopsy specimens of differing histologies and correlated these data with clinicopathological features.…”

Although the CDH13 gene has been shown to undergo epigenetic silencing by promoter methylation in many types of tumors, hypermethylation of this gene in Barrett's-associated esophageal adenocarcinogenesis has not been studied. Two hundred fifty-nine human esophageal tissues were therefore examined for CDH13 promoter hypermethylation by real-time methylation-specific PCR. CDH13 hypermethylation showed discriminative receiveroperator characteristic curve profiles, sharply demarcating esophageal adenocarcinoma (EAC) from esophageal squamous cell carcinoma (ESCC) and normal esophagus (NE) (p < 0.0001). CDH13 normalized methylation values (NMV) were significantly higher in Barrett's esophagus (BE), dysplastic BE (D) and EAC than in NE (p < 0.0000001). CDH13 hypermethylation frequency was 0% in NE but increased early during neoplastic progression, rising to 70% in BE, 77.5% in D and 76.1% in EAC. Both CDH13 hypermethylation frequency and its mean NMV were significantly higher in BE with than without accompanying EAC. In contrast, only 5 (19.2%) of 26 ESCCs exhibited CDH13 hypermethylation. Furthermore, both CDH13 hypermethylation frequency and its mean NMV were significantly higher in EAC than in ESCC, as well as in BE or D vs. ESCC. Interestingly, mean CDH13 NMV was significantly lower in short-segment than in long-segment BE, a known clinical risk factor for neoplastic progression. Similarly, BE segment length was significantly lower in specimens with unmethylated than with methylated CDH13 promoters. 5-aza-2 0 -deoxycytidine treatment of OE33 EAC and KYSE220 ESCC cells reduced CDH13 methylation and increased CDH13 mRNA expression. These findings suggest that hypermethylation of CDH13 is a common, tissue-specific event in human EAC, occurs early during BE-associated neoplastic progression, and correlates with known clinical neoplastic progression risk factors.

“…It has been shown that some genes are high frequently methylated in tumor tissue DNA obtained from NPC primary tumors, but not in normal tissues (Pan et al 2005;Sun et al 2007;Zhang et al 2007;Li, Shu, et al 2011). These genes are ideal candidate to serve as biomarkers for detection of NPC.…”

There is growing evidence supporting a role for tumor suppressor as targets in aberrant mechanisms of DNA hypermethylation. Methylation in the promoter of tumor suppressor always plays important roles in pediatric Acute Myeloid Leukemia (AML). CDH13 gene is a tumor suppressor involved in tumorigenesis, metastasis and apoptosis in a variety of tumors. In this study, we are trying to investigate whether CDH13 was down regulated by promoter methylation in pediatric AML. MRNA transcriptional expression levels of CDH13 were evaluated by semi-quantitative PCR and real-time PCR. Methylation status of CDH13 prompter was investigated by Methylation Specific PCR (MSP) and Bisulfate Genomic Sequencing (BGS). CDH13 mRNA transcription was inactivated in AML cell lines. Promoter of CDH13 was aberrantly methylated in 55.6% (5/9) leukemia cell lines. Promoter aberrant methylation of CDH13 was detected in 34.2% (24/70) of the cases of pediatric AML. The methylation of CDH13 promoter could be detected in all FAB subtypes. There were no significant differences in clinical features between patients with and without CDH13 methylation. Expression of CDH13 was significantly lower in AML patients group compared to normal bone marrow (NBM) control samples .The expression of CDH13 in thirty controls was significantly higher than pediatric AML patients. Both patients with CDH13 methylation (n=24) and those without CDH13 methylation (n=46) had significantly lower CDH13 transcript than controls (p<0.001). CDH13 transcript was significantly lower in patients with methylated CDH13 than those without methylated CDH13 (p=0.036). Inactivation of CDH13 by promoter hypermethylation is frequent event in pediatric AML. Our results suggest that hypermethylation of CDH13 promoter might be one of early events in the development of pediatric AML.
