About this Research Topic
Doubtlessly, the epigenome plays an important role in controlling gene expression and results in MSK disorders when dysregulated. For example, hypermethylation of CpG islands of bone regulators, like SOST and DKK1, are present in postmenopausal osteoporotic women, while m6A modification can serve as a novel epitranscriptomic marker. A plethora of microRNAs (miRs) have also been shown to affect skeletal (osteomiRs) and muscle (myomiRs) tissues. In addition, non-coding RNAs are being revealed as increasingly important in epigenetic regulation of MSK tissues. For instance, lncRNAS can act as sponges of miRs, and circRNAs are confirmed to play important roles in regulating cellular processes and diseases via large and complex networks involving mRNAs, miRNAs, and proteins. However, the detailed epigenetic mapping and how this regulates normal homeostasis, MSK pathogenesis, as well as the interaction with aging has not been described for a number of genes. In this Research Topic we welcome articles that encompass the latest advances and provide a comprehensive update in the field.
This Research Topic welcomes basic, clinical, and translational researchers in the musculoskeletal field regarding the epigenetic basis of gene regulation to submit original research articles, reviews, and hypothesis-driven papers addressing important issues such as, but not limited to:
• New advances in understanding the epigenome (novel modifiers, microRNAs etc.) and how these molecules affect the musculoskeletal tissues in health, disease, and aging
• Use of animal models (rodents, equine etc.) to unravel how epigenetic mechanisms can regulate gene expression and control the (patho)physiology of the musculoskeletal system
• Development of in vitro models to elucidate the epigenetic effect on cellular functions of bone cells, myocytes, chondrocytes, tendinocytes, etc.
• Genome-wide human or animal studies to detect epigenetic modifications in age-related musculoskeletal disorders and utilization of these changes as biomarkers (e.g. circulating microRNAs, epitranscriptomics)
• Use of bioinformatics to incorporate epigenetic changes in musculoskeletal pathologies and unravel pathogenetic mechanisms by systems biology approaches
Keywords: Histone modifications, DNA methylation, epitranscriptomics, non-coding RNAs, musculoskeletal aging
