An Investigation into the Genomic Evolution of the Histone Gene
... The extremely high level of within and between species similarity of the histone gene family has lead to the proposal that the histone gene family is subject to concerted evolution. Both mechanisms of concerted evolution – unequal crossing over and gene conversion - have been documented to occur, an ...

Cancer epigenetics
Cancer epigenetics is the study of epigenetic modifications to the genome of cancer cells that do not involve a change in the nucleotide sequence. Epigenetic alterations are as important as genetic mutations in a cell’s transformation to cancer, and their manipulation holds great promise for cancer prevention, detection, and therapy. In different types of cancer, a variety of epigenetic mechanisms can be perturbed, such as silencing of tumor suppressor genes and activation of oncogenes by altered CpG island methylation patterns, histone modifications, and dysregulation of DNA binding proteins. Several medications which have epigenetic impact are now used in several of these diseases.
