About this Research Topic
The brain is a very complex organ consisting of numerous distinct types of cells. During brain development and cell specification, neural stem cells or progenitor cells gain ample diversity at the level of epigenomics and differentiate into a population of heterogeneous cells. The epigenomic programming of brain cells involves numerous molecular and cellular processes to direct the changes in DNA methylation, histone and RNA modifications. Pioneer transcription factors may serve as drivers to initiate the cascade of chromatin configuration changes, shifting the expression profiles of downstream genes. Together with epigenetic modifications on DNA and histones, multiple transcription factors may form regulatory modules to control chromatin remodeling and nucleosome positioning, in a cell-type specific manner. Recent advances in brain epi-transcriptome studies reveal the functional relevance of RNA modifications in brain cell specification, as well as the potential links among the epigenetic modifications on DNA, RNA, and histones. Genetic mutations in readers, writers, and erasers of these epigenetic modifications or the aberrations of gene and protein expressions in associated pathways may lead to neurodevelopmental disorders and malfunctioned brain cells. Remarkable progress in omics technology is changing our ability to identify biomarkers associated with the disease phenotypes (e.g. neural/brain disorders and aging progression) and heterogeneous drug responses.
This Research Topic welcomes manuscripts presenting the exciting advances in the field of epigenetics/epi-transcriptomics in brain tissue development, cellular function specification, and neurodevelopmental disorders. Topics of interest include, but are not limited to the following eight sections:
I. Mechanisms in regulation and brain function with regards to histone modifications and DNA methylation, especially of 5-hydroxymethylcytosine (5hmC)
II. Mechanisms in regulation and brain functional roles of RNA methylation including N6-methyladenosine (m6A), 5-methylcytosine (5mC), and 5-hydroxymethylcytosine (5hmC)
III. Crosstalk among transcription factors and the machinery of histone and DNA modifications during brain development
IV. Blood-based epigenetics research for brain-based disorders
V. Large-scale genetic or epigenetic marker discovery linked to neurodevelopmental disorders for translational and personalized medicine
VI. Bioinformatics tools with novel statistical approaches, machine learning, neural nets or computational procedures/pipelines to provide unique insight in data interpretation for brain single cell analysis, “omics” data integration and mining
VII. Network, pathway, and functional analysis for investigation of dynamic linkages between measured DNA to mRNA and from mRNA to proteins and metabolites, and the influence of the environment on the expression of genes (epigenomics) associated with the disease phenotypes and drug responses (e.g. neural disorder and aging progression such as MS, Parkinson disease, multiple sclerosis, depression, drug additions, aging, mental health etc.)
VIII. Review articles on the latest advances in brain epigenetic mechanisms or recent development of experimental and analytical tools for (RNA)-epigenetic/omics studies with applications to neural/brain disorder and aging progressions.
Please note that abstract submission is not compulsory.
