摘要
The occurrence of cancer entails a series of genetic mutations that favor uncontrollable tumor growth.It is believed that various factors collectively contribute to cancer,and there is no one single explanation for tumorigenesis.Epigenetic changes such as the dysregulation of enzymes modifying DNA or histones are actively involved in oncogenesis and inflammatory response.The methylation of lysine residues on histone proteins represents a class of post-translational modifications.The human Jumonji C domain-containing(JMJD)protein family consists of more than 30 members.The JMJD proteins have long been identified with histone lysine demethylases(KDM)and histone arginine demethylases activities and thus could function as epigenetic modulators in physiological processes and diseases.Importantly,growing evidence has demonstrated the aberrant expression of JMJD proteins in cancer and inflammatory diseases,which might serve as an underlying mechanism for the initiation and progression of such diseases.Here,we discuss the role of key JMJD proteins in cancer and inflammation,including the intensively studied histone lysine demethylases,as well as the understudied group of JMJD members.In particular,we focused on epigenetic changes induced by each JMJD member and summarized recent research progress evaluating their therapeutic potential for the treatment of cancer and inflammatory diseases.
