Genome instability: a mechanistic view of its causes and consequences

TLDR
The causes and consequences of instability are reviewed with the aim of providing a mechanistic perspective on the origin of genomic instability.
Abstract
Genomic instability in the form of mutations and chromosome rearrangements is usually associated with pathological disorders, and yet it is also crucial for evolution. Two types of elements have a key role in instability leading to rearrangements: those that act in trans to prevent instability--among them are replication, repair and S-phase checkpoint factors--and those that act in cis--chromosomal hotspots of instability such as fragile sites and highly transcribed DNA sequences. Taking these elements as a guide, we review the causes and consequences of instability with the aim of providing a mechanistic perspective on the origin of genomic instability.

ATRPathwayInhibitionIsSyntheticallyLethalinCancerCells with ERCC1 Deficiency

TL;DR: It is concluded that ATR pathway–targeted drugs may offer particular utility in cancers with reduced ATR pathways function or reduced levels of ERCC4 activity, as well as triple-negative breast cancer cells and non–small cell lung cancer cells depleted of ER CC1 exhibited increased sensitivity to ATR pathogenicity drugs.

TL;DR: An analysis of scrotal asymmetry in ancient greek and roman sculptures revealed that although the ancient artists were correct in tending to place the right testicle higher, they were wrong in so far as they also tended to make the lower testicle the larger.

ATM Phosphorylates Histone H2AX in Response to DNA Double-strand Breaks

TL;DR: The results clearly establish ATM as the major kinase involved in the phosphorylation of H2AX and suggest that ATM is one of the earliest kinases to be activated in the cellular response to double-strand breaks.

Activation of the DNA damage checkpoint and genomic instability in human precancerous lesions

TL;DR: A panel of human lung hyperplasias, all of which retained wild-type p53 genes and had no signs of gross chromosomal instability, and found signs of a DNA damage response, including histone H2AX and Chk2 phosphorylation, p53 accumulation, focal staining of p53 binding protein 1 (53BP1) and apoptosis as discussed by the authors.
