As expected, the residual probability of carrying a BRCA1 mutation is markedly higher if the tumour in either the proband or the mother is known to be ER-negative.
According to previous reports in mice including whole-genome sequencing data, ENU-induced mutations were markedly biased toward mutations in A T base pairs (74.2 87%) [ 17, 27, 29, 30], which is considered to be a serious obstacle for random mutagenesis.
We examined other PPARγ target genes, identified from extensive microarray profiling of normal IDCs (I.S. and L.N., unpublished data) and found that responses to PPARγ agonist in DBD and LBD truncation mutation-containing cells were markedly attenuated whereas FSX mutation-containing cells exhibited responses that were either similar or only slightly reduced compared to WT cells.
It therefore follows that if a mutation were to markedly shift the equilibrium toward the KS* state, it might allow the occupancy of this state even when the polyketide is tethered to the ACP from the same module.
In the genome of the novel highly pathogenic PRRSV mutant, 4 deletions (2 deletions in nonstructural protein 2, one deletion in the 5′ untranslated region, and one deletion in the 3′ untranslated region), and some other point mutations, have occurred, which were markedly different from those found in any other previous virus isolate.
Interestingly, LHON fibroblasts with the 11778/ND4 mutation on a haplogroup H background were markedly more resistant to the toxicity of this compound, whereas no differences were observed with the other mutation/haplogroup combinations relative to controls.
The plots in the second to fourth rows from the top in Figure 34 show that the potential consequences for organismic fitness of differences in mutability under 64×4 vs. 4×4 mutation can be markedly mitigated or exacerbated by the likely highly heterogeneous average impact of the different amino-acid replacements.
Then, we showed that among methylated CpG sites, the mutation rate is markedly increased in low-intermediately 20-400% methylation level) to intermediately methylated CpG sites 40-600% methylation level) of the human genome.
The mutation yield on these two media also were markedly different, being greatly enhanced on DNB.
That might sound like a bad thing, but it turned out that when the mutations were present in their respective genes, cholesterol levels were markedly improved.
