Customised cisplatin treatment, based on a reduction in nucleotide excision repair function, is one attractive approach, whereas mitotic checkpoint gene status can be used to guide docetaxel therapy.
The molecular mechanisms that lead to loss of EcoKI methylation by ultraviolet light have been suggested based on its dependence on nucleotide excision repair function and on the primosome assembly activity of the PriA protein.
Although it does not alter the ERCC1 phenotype, the ERCC1 500C>T (rs11615) polymorphism has undergone a myriad of investigations into its role as a marker for nucleotide excision repair (NER) function in different races, diseases and treatment outcomes.
Resistance to trabectedin is associated with the loss of nucleotide excision repair (NER) function, with consequent increased sensitivity to cisplatin.
DinG is homologous to Rad3 in S. cerevisiae and XPD (ERCC2) in humans, which act in nucleotide excision repair, a function fulfilled by UvrD in E. coli.
Additionally, the examples of the SOS response, prophage excision, and relaxase function suggest targeting of these processes can potentially lead to the accumulation of toxic intermediates and cell death.
It is possible that either Lig3 is not the primary ligase that functions in DNA excision repair, or that its function in DNA repair can be efficiently substituted by another ligase (e.g., Lig1).
The conditional targeting vector used to disrupt the Cbx3 gene was designed with a FlpE-excisable neo-tk cassette placed in the intron separating exons 3 and 4. Disruption of Cbx3 gene function, after excision of the neo-tk by FlpE, would be effected by Cre excision of exons 2 and 3, which contain the alternative ATG start codons of the Cbx3 gene.
Unfortunately, loss of rotation is observed when tuberosity excision is used, impairing function and patient satisfaction.
Especially for the function in excision repair a specific binding site seems counterproductive to the occurrence of mutations only by chance not at specific sites.
