(Submitter supplied) The regenerative potential is governed by a complex process of transcriptional reprogramming, involving nuclear reorganization and dynamics in transcription factor binding patterns throughout the genome. The degree to which chromatin and epigenetic changes influence this process remains only partially understood. Here we provide a modified CUT&Tag protocol suitable for improved characterization and interrogation of epigenetic changes during of zebrafish caudal fin regeneration. more...

(Submitter supplied) Here we describe successful implementation of CUT&Tag for profiling protein-DNA interactions in zebrafish embryos. We optimized CUT&Tag protocol to generate high resolution maps of enrichment for the histone variant H2A.Z during zebrafish development. We were able to establish dynamics of H2A.Z genomic patterning from shield stage to 24hpf embryos. Our work demonstrates the power of combining CUT&Tag with the strengths of the zebrafish system to better understand the changing embryonic chromatin landscape and its roles in shaping development.

(Submitter supplied) Epigenetics helps define current cell states, yet also shapes how cells respond to external cues such as differentiation or stress. The epigenetic plasticity of a cell describes how flexible this regulation is. Bivalent chromatin is an exemplar of epigenetic plasticity. This co-occurrence of the active-associated H3K4me3 and inactive-associated H3K27me3 histone modifications on opposite tails of the same nucleosome was first described in mouse embryonic stem cells where it is found at promoters of key developmental genes. more...

(Submitter supplied) Mammalian genomes likely encode all gene products required to regenerate an amputated limb, yet they lack the correct instructions for strategically modulating those gene products to accomplish limb regeneration. Zebrafish and many other non-mammalian vertebrates possess these instructions, which exist as gene cis-regulatory elements. Here, to identify candidate tissue regeneration enhancer elements (TREEs) important for zebrafish fin regeneration, we performed ATAC-seq from bulk tissue or purified fibroblasts of uninjured and regenerating caudal fins. more...

(Submitter supplied) Chromatin accessibility mapping is a powerful approach to identify potential regulatory elements. In the popular ATAC-seq method, Tn5 transposase inserts sequencing adapters into accessible DNA (‘tagmentation’). CUT&Tag is a tagmentation-based epigenomic profiling method in which antibody tethering of Tn5 to a chromatin epitope of interest profiles specific chromatin features in small samples and single cells. more...

(Submitter supplied) Background: Zebrafish can faithfully regenerate injured fins through the formation of a blastema, a mass of proliferative cells that can grow and develop into the lost body part. After amputation, various cell types contribute to blastema formation, where each cell type retains fate restriction and exclusively contributes to regeneration of its own lineage. Epigenetic changes that are associated with lineage restriction during regeneration remain underexplored. more...

(Submitter supplied) Very little is known on the nature of epigenetic states in developing zebrafish despite its growing importance as a model organism in developmental biology. We report histone modifications on promoters of pluripotency genes in zebrafish embryos at the mid-late blastula transition (MBT+) stage. We identify three classes of expressed genes based on these profiles: (1) those with a promoter occupied by marks of active genes without any repressive marks; (2) those co-occupied by both activating and repressive modifications; of these genes, klf4 was notably found to be mosaically expressed in the embryo, possibly accounting for this epigenetic pattern; (3) those occupied by repressive marks with, surprisingly, little not acetylated H3K9 or H4. more...

(Submitter supplied) Genomic reprogramming and cellular dedifferentiation are critical to the success of de novo tissue regeneration in lower vertebrates such as zebrafish and axolotl. ChIP-seq of the histone modifications H3K27Ac, H3K27me3, and H3K4me3 was used to characterize early epigenetic changes in a zebrafish in vivo model of adult muscle regeneration.

(Submitter supplied) Histone modifications play an integral role in plant development, but have been poorly studied in woody plants. Investigating chromatin organization in wood-forming tissue and its role in regulating gene expression allows us to understand the mechanisms underlying cellular differentiation during xylogenesis (wood formation) and identify novel functional regions in plant genomes. However, woody tissue poses unique challenges for using high-throughput chromatin immunoprecipitation (ChIP) techniques for studying genome-wide histone modifications in vivo. more...

(Submitter supplied) Histone modifications play critical roles in regulating developmental genes expression during embryo development in mammals1,2. However, genome-wide analysis of histone modifications in pre-implantation embryos has been impeded by technical difficulties and the scarcity of required materials. Here, by using a small-scale chromatin immunoprecipitation sequencing (ChIP-seq) method3, for the first time, we mapped the genome-wide profile of histone H3 lysine 4 trimethylation (H3K4me3) and histone H3 lysine 27 trimethylation (H3K27me3), associated with gene activation and repression respectively, in mouse pre-implantation embryos. more...

(Submitter supplied) In this study, we have applied ChIP-Seq to identify putative regulatory elements throughout the zebrafish genome. For this purpose we identified sequences within the zebrafish genome that associate with H3K4me1 and H3K4me3, which are epigenetic modifications known to be associated with active cis-regulatory elements in other species.

(Submitter supplied) Histone modifications are considered as fundamental epigenetic regulators that control many crucial cellular processes 1. However, whether these marks can be passed on from gametes to the next generation in mammals is a long-standing question that remains unclear. By developing a highly sensitive approach, STAR ChIP-seq, we provided a panoramic view of the landscape of H3K4me3, a histone hallmark for transcription initiation 2, from developing gametes to postimplantation embryos. more...
