DNA methylation is a conserved chemical modification, by which methyl groups are added to the cytosine of DNA molecules. Methylation can influence gene expression without changing the sequence of a particular gene. This epigenetic effect is an intriguing phenomenon that has puzzled biologists for years. By probing the temporal and spatial patterns

In recent years, DNA methylation research has been accelerated by the advent of nanopore sequencers. However, read length has been limited by the constraints of base conversion using the bisulfite method, making analysis of chromatin content difficult. The read length of the previous method combining bisulfite conversion and long-read sequencing

Characterizing the molecular mechanisms regulating gene expression is crucial for understanding the regulatory processes underlying physiological responses to environmental and developmental signals in eukaryotes. The covalent modification of histones contributes to the compaction levels of chromatin, as well as the recruitment of the

In the field of chromatin biology, a major goal of understanding the roles of histone post-translational modifications is to identify the proteins and domains that recognize these modifications. Synthetic histone peptides containing one or more modifications are a key tool to probe these interactions in pull-down assays with recombinant proteins

Primary somatosensory neurons, whose cell bodies reside in the dorsal root ganglion (DRG) and trigeminal ganglion, are specialized to transmit sensory information from the periphery to the central nervous system. Our molecular understanding of peripheral sensory neurons has been limited by both their heterogeneity and low abundance compared with

DNA methylation in gene promoters plays a major role in gene expression regulation, and alterations in methylation patterns have been associated with several diseases. In this context, different software suites and statistical methods have been proposed to analyze differentially methylated positions and regions. Among them, the novel statistical

We previously introduced Cleavage Under Targets & Tagmentation (CUT&Tag), an epigenomic profiling method in which antibody tethering of the Tn5 transposase to a chromatin epitope of interest maps specific chromatin features in small samples and single cells. With CUT&Tag, intact cells or nuclei are permeabilized, followed by successive
