Genome Instability and γH2AX [PDF]
International Journal of Molecular Sciences, 2017 γH2AX has emerged in the last 20 years as a central player in the DDR (DNA damage response), with specificity for DSBs (double-strand breaks). Upon the generation of DSBs, γ-phosphorylation extends along megabase-long domains in chromatin, both sides of the damage.

Bacterial Genome Instability [PDF]
Microbiology and Molecular Biology Reviews, 2014 SUMMARY Bacterial genomes are remarkably stable from one generation to the next but are plastic on an evolutionary time scale, substantially shaped by horizontal gene transfer, genome rearrangement, and the activities of mobile DNA elements. This implies the existence of a delicate balance between the maintenance of genome stability and the ...

Genomic Instability in Cancer [PDF]
Cold Spring Harbor Perspectives in Biology, 2013 One of the fundamental challenges facing the cell is to accurately copy its genetic material to daughter cells. When this process goes awry, genomic instability ensues in which genetic alterations ranging from nucleotide changes to chromosomal translocations and aneuploidy occur.

MicroRNAs and genomic instability [PDF]
Seminars in Cancer Biology, 2007 A new species of non-coding RNA, microRNAs (miRNAs) has been identified that may regulate the expression of as many as one third to one half of all protein encoding genes. MicroRNAs are found throughout mammalian genomes, but an association between the location of these miRNAs and regions of genomic instability (or fragile sites) in humans has been ...

The Swr1 chromatin-remodeling complex prevents genome instability induced by replication fork progression defects. [PDF]
, 2018 Genome instability is associated with tumorigenesis. Here, we identify a role for the histone Htz1, which is deposited by the Swr1 chromatin-remodeling complex (SWR-C), in preventing genome instability in the absence of the replication fork/replication ...

Transcription as a Threat to Genome Integrity [PDF]
, 2016 Genomes undergo different types of sporadic alterations, including DNA damage, point mutations, and genome rearrangements, that constitute the basis for evolution.

Genomic Instability and Cancer [PDF]
Journal of Carcinogenesis & Mutagenesis, 2014 Genomic instability is a characteristic of most cancer cells. It is an increased tendency of genome alteration during cell division. Cancer frequently results from damage to multiple genes controlling cell division and tumor suppressors. It is known that genomic integrity is closely monitored by several surveillance mechanisms, DNA damage checkpoint ...

Genetic control of meiosis surveillance mechanisms in mammals
Frontiers in Cell and Developmental Biology, 2023 Meiosis is a specialized cell division that generates haploid gametes and is critical for successful sexual reproduction. During the extended meiotic prophase I, homologous chromosomes progressively pair, synapse and desynapse. These chromosomal dynamics
