TLDR
The enzymology of the process is discussed, followed by studies on DSB repair in living cells, and a historical context for the current view of HR is provided and how DSBs are processed during HR as well as interactions with other D SB repair pathways are described.Abstract:
In this review, we discuss the repair of DNA double-strand breaks (DSBs) using a homologous DNA sequence (i.e., homologous recombination [HR]), focusing mainly on yeast and mammals. We provide a historical context for the current view of HR and describe how DSBs are processed during HR as well as interactions with other DSB repair pathways. We discuss the enzymology of the process, followed by studies on DSB repair in living cells. Whenever possible, we cite both original articles and reviews to aid the reader for further studies.read more

TL;DR: It is proposed that increased rDNA instability and the reduced DSB repair capacity of old cells contribute to the progressive accumulation of global chromosomal DNA breaks, where exceeding a threshold of genomic DNA damage ends the replicative life span.

TL;DR: Inhibition of Jak2–Stat5a/b signaling sensitizes prostate cancer to radiation and, therefore, may provide an adjuvant therapy for radiation to reduce radiation-induced damage to the neighboring tissues.
