摘要: PR结构域蛋白(PRDM)基因在细胞分化和增殖中发挥关键作用。该家族基因成员大多是抑癌基因,在多种肿瘤中异常表达参与肿瘤的发生。DNA异常甲基化常使这些基因沉默,可能发生在肿瘤早期,可以通过去甲基化使肿瘤发生逆转,为肿瘤的防治提供一条新的思路。

Abstract: PRDI-BF1 and RIZ homology domain containing proteins (PRDM) play a key role in cell differentiation and proliferation. Most members of the PRDM gene family are  tumor suppressor genes which involved in tumorigenesis and abnormal expression in a variety of tumors. Aberrant DNA methylation often silences these genes, which may occur in the early stage of tumor. Cancer can be reversed by demethylation, which provides a new way for cancer treatment.
