Cell‐type‐ and cell‐state‐specific patterns of covalent modifications on DNA and histone tails form global epigenetic profiles that enable spatiotemporal regulation of gene expression. These epigenetic profiles arise from coordinated activities of transcription factors and epigenetic modifiers, which result in cell‐type‐specific outputs in response to dynamic environmental conditions and signalling pathways. Recent mouse genetic and functional studies have highlighted the physiological significance of global DNA and histone epigenetic modifications in skin. Importantly, specific epigenetic profiles are emerging for adult skin stem cells that are associated with their cell fate plasticity and proper activity in tissue regeneration. We can now begin to draw a more comprehensive picture of how epigenetic modifiers orchestrate their cell‐intrinsic role with microenvironmental cues for proper skin development, homeostasis and wound repair. The field is ripe to begin to implement these findings from the laboratory into skin therapies.

“…Epigenetic mechanisms are important in regulating the wound healing processes, including keratinocyte proliferation, differentiation, and migration, together with dermal regeneration and neoangiogenesis (Lewis et al, 2014). The histone deacetylase (HDAC) inhibitor trichostatin A (TSA) has potent antifibrogenic effects in a mouse model of bleomycininduced skin fibrosis (Huber et al, 2007).…”

Keloids are pathological scars characterized by excessive extracellular matrix production that are prone to form in body sites with increased skin tension. CAV1, the principal coat protein of caveolae, has been associated with the regulation of cell mechanics, including cell softening and loss of stiffness sensing ability in NIH3T3 fibroblasts. Although CAV1 is present in low amounts in keloid fibroblasts (KFs), the causal association between CAV1 down-regulation and its aberrant responses to mechanical stimuli remain unclear. In this study, atomic force microscopy showed that KFs were softer than normal fibroblasts with a loss of stiffness sensing. The decrease of CAV1 contributed to the hyperactivation of fibrogenesis-associated RUNX2, a transcription factor germane to osteogenesis/chondrogenesis, and increased migratory ability in KFs. Treatment of KFs with trichostatin A, which increased the acetylation level of histone H3, increased CAV1 and decreased RUNX2 and fibronectin. Trichostatin A treatment also resulted in cell stiffening and decreased migratory ability in KFs. Collectively, these results suggest a role for CAV1 down-regulation in linking the aberrant responsiveness to mechanical stimulation and extracellular matrix accumulation with the progression of keloids, findings that may lead to new developments in the prevention and treatment of keloid scarring.

“…Cellular responses after injury rely on transient changes in the expression of a great number of genes. Recent findings suggest that epigenetic changes play an important part in the modification of gene expression, but the mechanisms of dynamic epigenetic remodeling during wound healing are virtually unexplored (Lewis et al, 2014). Within this context, the study by Na et al (2016) focuses on the role of the Jumonji domaincontaining protein D3 (JMJD3) histone demethylase in modulating the function of keratinocytes after injury.…”

Epigenetic Control of Skin Re-Epithelialization: the NF-kB/JMJD3 Connection

Major changes in gene expression must occur at wound site to establish the cellular responses required for rapid healing. Although epigenetic remodeling plays a role in gene modulation, the mechanisms responsible for epigenetic regulation during healing are largely unknown. The study from Na et al. sheds light on the role of histone demethylase Jumonji domain-containing protein D3 in promoting keratinocyte function after injury, and it links Jumonji domain-containing protein D3-dependent gene expression to NK-kB activity.
