Differences in the drug effect on Mp load existed between subject groups.
IBC and DCIS sample populations were considered separately in order to determine if any patterns existed in the mutation load of the individual sample types as well as to discover the presence of any interactions between the two tissue types.
In oral and esophageal cancers, the p53 mutation load has been shown to be proportional to the extent of tobacco consumption, with an almost fourfold increase in mutation prevalence in heavy smokers as compared to nonsmokers (Brennan et al., 1995).
Thus, male age has been considered to be a reliable indicator of mutation load [1], [12] [14].
It is another ethically difficult indication, as the possibility exists that there are no zero-mutation embryos for transfer but just embryos with a low mutation load (that is, the ratio of mutant to normal mtDNA) under a certain disease-specific threshold, meaning that the risk for an affected child is not eliminated but only reduced.
To obtain insight into the mutation load in specific genes ensuing differentiation and proliferation in SCs, we mapped our mutations to expression data generated by the FANTOM5 project28.
p53 mutations are frequent in tobacco-related cancers and the mutation load is often higher in cancers from smokers than from nonsmokers.
Our results showed a mutation load increase of 5 6-fold with increased age and suggested a link between the increased mutation burden in old SCs and the defective response of aged muscles to training.
Our analyses reveal an accumulation of 13 mutations per genome per year that results in a 2 3-fold higher mutation load in active genes and promoters in aged SCs.
