Epigenomic stress response. Knockdown of DNA methyltransferase 1 triggers an intra-S-phase arrest of DNA replication and induction of stress response genes.
The DNA methylation pattern is an important component of the epigenome that regulates and maintains gene expression programs. In this paper, we test the hypothesis that vertebrate cells possess mechanisms protecting them from epigenomic stress similar to DNA damage checkpoints. We show that knockdown of DNMT1 (DNA methyltransferase 1) by an antisense oligonucleotide triggers an intra-S-phase ar...
متن کاملStress response in cyanobacteria
Cyanobacteria are an important source of natural products. In this article, we briefly review the responses of cyanobacteria to different stresses. Abiotic stresses (temperature, salt, heavy metals, metalloid and ultraviolet (UV) influence cell growth and metabolism in cyanobacteria. Salt stress is a major abiotic factor that decrease...
متن کاملSnapShot: Epigenomic Assays
This SnapShot depicts key sequencing-based methods used in the analysis of epigenomes, including (1)bisulfite sequencing, (2) chromatin immunoprecipiation sequencing, (3) determination of open chromatin, and (4) 3D chromatin capture.
متن کاملEpigenomic profiling using microarrays.
Genes occupy only a minor fraction of genomes such as ours; however, histone and nonhistone chromosomal proteins and methylated DNA bases are distributed over both genic and nongenic regions. These widespread "epigenomic" features can be mapped and characterized by alternative applications of the same microarray technologies that have been used for conventional transcriptional profiling. Here w...
متن کاملDetection of Epigenomic Network Community
In this paper we propose network methodology to infer prognostic cancer biomarkers based on the epigenetic pattern DNA methylation. Epigenetic processes such as DNA methylation reflect environmental risk factors, and are increasingly recognised for their fundamental role in diseases such as cancer. DNA methylation is a gene-regulatory pattern, and hence provides a means by which to assess genom...
