Abstract
- Clear cell renal cell carcinoma (ccRCC) is a common urologic malignancy. Understanding of the transcriptional regulation of oncogenes and tumor suppressor genes involved is critical for the development of the treatments for renal tumors. Using ccRCC subdivision of the TCGA dataset, we identified NR0B2 encoding orphan nuclear receptor as a tumor suppressor candidate in renal tissue. In independent cohort of primary renal tumors, quantitative PCR experiments confirmed significant suppression of NR0B2 mRNA in 86% of ccRCC samples studied. In 80% of these cases, we detected the hypermethylation of the NR0B2 pro-moter region. These results suggest that NR0B2 is a tumor suppressor gene in ccRCC, and that the hypermethylation of promoter region is the main mechanism of its downregulation.
