Crosstalk among Epigenetic Pathways Regulates Neurogenesis
The process of neurogenesis includes neural stem cell proliferation, fate specification, young neuron migration, neuronal maturation, and functional integration into existing circuits. Although neurogenesis occurs largely during embryonic development, low levels but functionally important neurogenesis persists in restricted regions of the postnatal brain, including the subgranular zone of the d...
متن کاملEpigenetic crosstalk: a molecular language in human metabolic disorders.
Technological breakthroughs are emphasizing the impact of epigenetic mechanisms in human health highlighting the importance of a fine-tune orchestration of DNA methylation, micro RNAs, histone modifications, and chromatin structure. Transcriptional regulators sense the concentration of intermediary metabolites associated to a wide variety of biological processes including the long-term imprinti...
متن کاملDifferent epigenetic layers engage in complex crosstalk to define the epigenetic state of mammalian rRNA genes.
Eukaryotic cells contain several hundred ribosomal RNA (rRNA) genes (rDNA), a fraction of them being silenced by epigenetic mechanisms. The presence of two epigenetically distinct states of rRNA genes provides a unique opportunity to decipher the molecular mechanisms that establish the euchromatic, i.e. transcriptionally active, and the heterochromatic, i.e. transcriptionally silent, state of r...
متن کاملEpigenetic Regulation by ATP-Dependent Chromatin-Remodeling Enzymes: SNF-ing Out Crosstalk.
Cells utilize precise mechanisms to access genomic DNA with spatiotemporal accuracy. ATP-dependent chromatin-remodeling enzymes (also known simply as "remodelers") comprise a specialized class of enzymes that is intimately involved in genomic organization and accessibility. Remodelers selectively position nucleosomes to either alleviate chromatin compaction or achieve genomic condensation local...
متن کاملEpigenetic mechanisms underlie the crosstalk between growth factors and a steroid hormone
Crosstalk between growth factors (GFs) and steroid hormones recurs in embryogenesis and is co-opted in pathology, but underlying mechanisms remain elusive. Our data from mammary cells imply that the crosstalk between the epidermal GF and glucocorticoids (GCs) involves transcription factors like p53 and NF-κB, along with reduced pausing and traveling of RNA polymerase II (RNAPII) at both promote...
