In addition, given that our mutant mice have a single base deletion as often observed in patients, they could represent a useful model to set up and test novel gene therapy approaches, such as in vivo gene correction by homologous recombination (38), stem cells, or induced pluripotent stem cells from patients.
Instead, AS-15MF and AS-ATN bear a 3 base deletion (I102del) in the same gene (confirmed by dideoxysequencing).
In addition, sequence analysis revealed that ZFN-induced mutations such as base substitution, deletion, or insertion were generated in the ZFN cleavage site of EGFP-expression negative cells that were cloned from ZFN-treated cells, thereby showing it was possible to disrupt (i.e., knock out) the function of the EGFP gene in porcine somatic cells.
Low frequency tags were discounted under the assumption that many could have arisen through sequencing errors such as base substitution, deletion or addition at a single position [ 14].
All PTEN mutations involved codons previously found in other tumors as bearing single base deletions or mutations (ID 5856, ID 5292 and ID 5821).
The comparison showed that none of the clinical strains had base deletions, as observed for S. mutans Ingbritt.
On the other hand, ROS-induced genotoxic damage can induce structural changes in DNA, such as chromosomal rearrangement, strand breaks, base deletions, pryrimidine dimers, cross-links and base modifications, mutations, and other genotoxic effects [ 5, 6].
Each of FN and UV-B radiations can induce ROS in PMCs by special interference with DNA leading to induction of structural changes in DNA, such as chromosomal rearrangement, strand breaks, base deletions, pryrimidine dimers, cross-links and base modifications, mutations, and other genotoxic effects [ 5, 6].
Single base deletions affecting C·G base pairs result in about 30% smaller hybridization signals than deletions affecting A·T base pairs.
Analysis of the E1 sequence of Sakamotowase revealed that it contained a dysfunctional allele, e1-fs, that produced a loss-of-function truncated protein due to a premature stop codon, which arose as a consequence of a single-base deletion [ 13].
