Progress in epigenetic study of clear cell renal cell carcinoma / 中国病理生理杂志

ABSTRACT

The epigenetic changes of clear cell renal cell carcinoma(ccRCC )are considered to be the main molecular mechanisms of its pathogenesis ,including DNA methylation ,histone modification ,microRNA change ,and so on.DNA methyltransferases(DNMTs)catalyze the occurrence of DNA methylation.DNA methylation changes are mani-fested in the overall low methylation of the genome and the high methylation of specific sites ,which were involved in the de-velopment of ccRCC by affecting the expression of tumor suppressor genes.Due to histone-modified enzyme involvement ,histone modification is shown as possible genetic reversal.MicroRNA plays an important role in the abnormal expression of ccRCC genes.With the studies of epigenetic mechanism and molecular pathology ,it is important to explore the mechanisms and to seek effective early diagnosis ,treatment and prognosis intervention of ccRCC.
