To address this issue, primary mouse cells, haploinsufficient for one or two proteins, ATM and RAD9, related to the cellular response to DNA damage were examined. (aacrjournals.org)
The results show that cells having low levels of both ATM and RAD9 proteins are more sensitive to transformation by radiation, have different DNA double-strand break repair dynamics and are less apoptotic when compared with wild-type controls or those cells haploinsufficient for only one of these proteins. (aacrjournals.org)
Our conclusions are that under stress conditions, the efficiency and capacity for DNA repair mediated by the ATM/RAD9 cell signaling network depend on the abundance of both proteins and that, in general, DNA repair network efficiencies are genotype-dependent and can vary within a specific range.

Because the effect of haploinsufficiency for one protein is relatively small, we hypothesize that predisposition to cancer could be a result of the additive effect of heterozygosity for two or more genes, critical for pathways that control DNA damage signaling, repair or apoptosis.

Homologous5
Both homologous recombination, in which the ends of the broken DNA seek out intact templates with the same sequence, and nonhomologous end-joining pathways are found in Saccharomyces as they are in humans. (brandeis.edu)
This "in vivo biochemistry" approach has enabled us to demonstrate that there are in fact several independent, competing pathways of homologous recombination, each with its own genetic requirements. (brandeis.edu)
The two most commonly used pathways to repair DSBs in higher eukaryotes include non-homologous end joining (NHEJ) and homologous recombination (HR). NHEJ is considered to be error-prone, intrinsically mutagenic quick fix remedy to seal together the broken DNA ends and restart replication. (springeropen.com)

Tumor2
Another conclusion from most of the cases is that animals or cells haploinsufficient for the specified proteins have higher transformation rates after DNA damage is induced, but when their DNA is not significantly damaged by exogenous sources, tumor development rates are the same as for their wild-type counterparts.
