There have been spectacular advances in mechanistically defining parameters of epigenetic control. From a regulatory perspective, post-replication modifications of DNA, post-transcriptional modifications of histone proteins, the regulatory contributions of non-coding RNAs and mitotic gene bookmarking are becoming increasingly recognized as pivotal for biological control.
Beyond biological relevance, the central role of epigenetic regulation in human disease is minimally understood. It is difficult to overstate the growing awareness of epigenetic regulation in a broad spectrum of biological processes that are obligatory for development, differentiation, proliferation, tissue remodeling and physiological control of homeostasis. There is growing recognition for the epigenetic contribution to the initiation and progression of human diseases that include cancer, neurological diseases, metabolic syndromes and skeletal disorders.
In addition to the value of epigenetic parameters of control as biomarkers, there is increasing evidence for epigenetic-based druggable targets that are selective and with minimal off-target consequences.
We have assembled a series of research articles and reviews that were recently published in the Journal of Cellular Physiology on epigenetic control. These articles illustrate the challenges and opportunities of epigenetic control for establishing novel dimensions to biological regulation and for transformational advances in the diagnosis and treatment of human disease.

Figure 1. Combinatorial epigenetic signatures for a comprehensive personalized therapy. Four major epigenetic mechanisms are depicted that regulate gene expression in a rapid and reversible manner. Extensive studies have shown interplay and tight integration between these mechanisms (shown as solid, dark green lines). For example, DNA methylation and histone modifications often function in concert to regulate gene expression both synergistically and in an opposing fashion. It is becoming evident that these two epigenetic mechanisms also function together with non-coding RNA-mediated silencing of gene expression; X-chromosome inactivation is a well-understood example of integrative regulation of gene expression by epigenetic means. Mitotic bookmarking of genes is a recently described epigenetic mechanisms and its integration with three well-established mechanisms is only being explored (shown as dotted, light green lines). A comprehensive understanding of these epigenetic mechanisms and their interplay will yield an epigenetic landscape of normal cells and how it is altered in cancer, leading to the development of viable personalized therapy.

Stem Cell Biology
Published: February 2014
Advances in stem cell biology are providing a platform for mechanistic insight into biological control in areas that have been historically confined to insightful, but descriptive observations. Equally important, lessons learned from understanding the rules that govern pluripotency and lineage commitment are paving the way for breakthroughs in regenerative medicine and cell-based therapies. We have assembled a series of research articles and reviews on stem cell biology that were recently published in the Journal of Cellular Physiology. These articles encapsulate fundamental dimensions of control in stem cells that are beginning to be understood from the perspectives of genetic and epigenetic control as well as within the context of regulatable plasticity.

Journal of Cellular Physiology is pleased to announce their Virtual Issue on recent hot topics.
Evidence for pivotal roles of genetic and epigenetic control of gene expression is rapidly accruing. The importance of genetic and epigenetic mechanisms is expanding understanding of biological processes. Applications for therapeutically targeting cancer cells are emerging. These strategies are featured in six recent papers that were recently published in Journal of Cellular Physiology. Aberrant regulation in transformed and tumor cells is presented and the power of experimental strategies including systems of biology and genomic approaches are presented to illustrate the necessity for defining regulatory networks that integrate parameters of control which are operative in biology and compromised in pathology.
