Abstract:
:DNA methylation plays an important role in the genesis and progression of tumor diseases. To identify new DNA methylation markers possibly associated with the clinical characteristics of renal cell carcinoma (RCC), we investigated loci in the sarcosine dehydrogenase (SARDH) gene. SARDH is involved in the metabolism of the glycine‑derivative sarcosine and is closely linked through a functional control loop. Statistical evaluation of methylation data and clinical characteristics of patients showed that kidney tumors with clinically aggressive features such as a high tumor stage, positive lymph nodes, distant metastases or a previously advanced tumor status exhibited significantly lower methylation of a locus in the SARDH gene. Moreover, SARDH methylation was found to be a significant prognostic factor for recurrence‑free survival in RCC patients showing statistical independence from the clinical prognosticators, grade, stage and state of metastasis. In conclusion, the methylation status of the SARDH‑CGI was identified as an independent prognostic candidate marker for RCC.
