Expression and significance of histone H3K27 demethylases in renal cell carcinoma.


ABSTRACT: The histone H3K27 demethylases UTX and JMJD3 are important regulatory factors that modulate gene expression by altering the physical state of chromatin. Previous studies have indicated an abnormal H3K27 methylation status in carcinogenesis. We therefore investigated the expression patterns of UTX and JMJD3 in renal cell carcinoma (RCC) and their roles in cancer development.The mRNA expression levels of the UTX and JMJD3 genes were determined in cancer tissues and adjacent normal tissues in 36 patients with primary RCC, using quantitative real-time-polymerase chain reaction. The UTX and JMJD3 protein contents were measured by western blotting and immunohistochemical analysis.UTX and JMJD3 transcripts were significantly increased in cancer tissues compared to normal tissues (P?
