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

The CRISPR/Cas9 technology has transformed our ability to edit eukaryotic genomes. Despite this breakthrough, it remains challenging to precisely knock-in large DNA sequences, such as those encoding a fluorescent protein, for labeling or modifying a target protein in post-mitotic cells. Previous efforts focusing on sequence insertion to the

Mitochondria are relatively small, fragmented, and abundant in the large embryos of Drosophila, Xenopus and zebrafish. It is essential to study their distribution and dynamics in these embryos to understand the mechanistic role of mitochondrial function in early morphogenesis events. Photoactivation of mitochondrially tagged GFP (mito-PA-GFP) is

The blood-brain barrier (BBB), a crucial protection mechanism in the central nervous system (CNS), is a selective barrier comprised of endothelial cells. It hampers the development of therapeutic and diagnostic tools for neurological diseases due to the poor penetration of most of these agents. Rationally engineered nanoparticles (NP) can

All eukaryotic cells are equipped with transmembrane lipid transporters, which are key players in membrane lipid asymmetry, vesicular trafficking, and membrane fusion. The link between mutations in these transporters and disease in humans highlights their essential role in cell homeostasis. Yet, many key features of their activities, their

Chemoresistance, the ability of cancer cells to overcome therapeutic interventions, is an area of active research. Studies on intrinsic and acquired chemoresistance have partly succeeded in elucidating some of the molecular mechanisms in this elusive phenomenon. Hence, drug-resistant cellular models are routinely developed and used to mimic the

Over the past decade, zebrafish have emerged as a powerful model for the study of vertebrate sleep and wake behaviors. Experimental evidence has demonstrated behavioral, anatomical, genetic, and pharmacological conservation of sleep between zebrafish and mammals, suggesting that discoveries in zebrafish can inform our understanding of mammalian

ATAC-seq (assay for transposase-accessible chromatin with high-throughput sequencing) is a powerful method to evaluate chromatin accessibility and nucleosome positioning at a genome-wide scale. This assay uses a hyperactive Tn5 transposase, to simultaneously cut open chromatin and insert adapter sequences. After sequencing, the reads generated

Mechanisms that target and destroy foreign nucleic acids are major barriers to horizontal gene transfer (HGT) in prokaryotes. Amongst them, restriction-modification (R-M) systems are found in ≥75% of the sequenced genomes in Bacteria and Archaea. Due to their high target sequence specificity and potent nucleolytic activity, R-M systems are used

RNA sequencing allows for the quantification of the transcriptome of embryos to investigate transcriptional responses to various perturbations (e.g., mutations, infections, drug treatments). Previous protocols either lack the option to genotype individual samples, or are laborious and therefore difficult to do at a large scale. We have developed a

Many of the current methods for enzyme purification and immobilization suffer from several drawbacks, such as requiring tedious multistep procedures or long preparation, and being environmentally unfriendly, due to the chemicals and conditions involved. Thus, a simple technique for direct purification and immobilization of target enzymes from cell
