Epigenetic mechanismssuch as DNA methylation,histone modifications,nucleosome positioning and non-coding RNAs are proven to have strong association with cancer. In particular,covalent post-translational modifications of histone proteins are known to play an important role in chromatin remodeling and thereby in regulation of gene expression. Further,histone modifications have also been associated with different aspects of carcinogenesis and have been studied for their role in the better management of cancer patients. In this review,we will explore and discuss how histone modifications are involved in cancer diagnosis,prognosis and treatment.展开更多

Initially, function of histone chaperones was thought to be only “histone carriers/vehicles”, but now with accumulating evidences they are known to be the key actors of histone metabolism. With this outburst of knowledge, histone chaperones are now placed at the center of gene regulation, having roles to play in DNA replication, repair and transcription. This review will focus on the current knowledge we have about the role of histone chaperones in regulating cellular processes and their relation to disease. In addition, we discuss the potential of histone chaperones as a therapeutic target.展开更多
