Next generation sequencing (NGS) is a method of non-Sanger-based high throughput DNA sequencing in which millions or even billions of DNA strands can be sequenced in parallel. Epigenetic researchers utilize NGS as an important tool to gain detailed and comprehensive insight into epigenetic modifications of genomes belonging to numerous species and from many different cell types. NGS minimizes the need for fragment-cloning methods often used in Sanger sequencing of genomes and yields significantly more throughput.

What Is RNA Methylation? RNA methylation is a reversible post-translational modification to RNA that epigenet...

Chromatin structures are regulated by various mechanisms including histone modification and chromatin remodeling, which involve the binding of transcription factors. By using tools such as chromatin immunoprecipitation, it is possible to gain further insight into the dynamic interactions between transcription proteins and components of chromatin, and to ultimately understand their roles in cellular fu...

Histone methylation causes transcription repression or activation, depending on the target sites. Histone methyltransferases (HMTs) control or regulate DNA methylation through chromatin-dependent transcription repression or activation. Measurement of histone methyltrasferase activity and quantification of histone methylation patterns have become pivotal in studying epigenetic regulation of genes, as well as inhibitor discovery.

Histone acetylation and histone deacetylation involve the addition or removal of an acetyl group on lysine residues in the N-terminal tail and on the surface of the nucelosome core of histone proteins. Acetylated and deacetylated histones are considered epigenetic tags within chromatin by relaxing (euchromatin) or tightening (heterochromatin) chromatin structure, subsequently increasing or decreasing gene transcription levels.

DNA and RNA damage refers to the structural and functional alteration of these nucleic acids. It can be caused by several factors, including oxidative stress, genotoxic/cytotoxic agents, ionizing radiation, industrial chemicals, and cancer chemotherapy. The Role of Oxidative Stress in DNA Damage Oxidative stress has been identified as one of the greatest factors in DNA and RNA damage. It occurs when there is an imbalance between the production of reactive oxygen s...

Targeted gene knockdown using small interfering RNA (siRNA) or antisense oligonucleotides has been valuable technology in studying gene function. Gene knockdown leads to the reduction of messenger RNA and subsequently decreased protein expression. Alternatively, CRISPR/Cas9-based gene editing is also a versatile method to alter the genome. These gene editing and silencing methods give researchers valuable insight into biological processes and especially diseases.

Various histone modifications, such as histone citrullination and histone phosphorylation, have been shown to epigenetically impact gene expression through different mechanisms. Adjusting epigenetic marks and changing chromatin structure – known as chromatin remodeling – as a result of these histone modifications can influence gene regulation in many tissue types. Studying these histone modifications provides researchers with valuable insight into cellular processes such as apoptosis, cel...
