As such, inhibitory effects of a DNA extraction method can differ per PCR assay, as shown by the comparison of our results with those of other authors [ 8, 16].
In particular, we were interested in following up on a prior paradoxical observation that demonstrated DNA methylation to be enriched at DNase hypersensitive, early-replicating euchromatin in non-cancer cell lines [ 14], suggesting that the effects of a DNA demethylating agent would be more likely to target this gene- and transcription-rich genomic compartment.
As CLDN4 was repressed with DNA hypermethylation in ovarian cells, in addition to H3K27me3 and histone acetylation, we also assessed the effects of a DNA methylation inhibitor, 5-aza-dC (alone or in combinations with DZNep or TSA), on CLDN4 expression in promoter-hypermethylated TOV-112D cells.
Collectively, our work demonstrates the successful development and application of a quantitative PE-4Cseq analysis pipeline, and illustrates for the first time the complex and diverse effects of a DNA deletion on both the local and global signatures of chromatin organization and gene expression.
To determine if the observed changes were specific to a hypoxic mechanism of cell death, or reflected a more general effect on apoptotic responses, we investigated the effects of a DNA-damaging agent.
The selection of these SNPs in DNA BER genes was based on their putative effect on protein function and/or previous evidence of associations with the risk of hepatobiliary tract cancers in the Asian (Chinese and Indian) populations 5 7and the combined effects of a DNA-repair gene and metabolic gene polymorphisms on CCA risk in Thailand.
Here we investigated the preventive and therapeutic effect of a MUC1 DNA vaccine on the pancreatic cancer.
Data obtained with the activation of the DNA damage checkpoint by etoposide provide an example of detectable modification of cell cycle suggesting that Capan-2 Fucci expressing spheroid models could be used to detect or to investigate the effect of a novel DNA damaging compound.
It is possible that defective centromere chromatin structures observed in mcl1 and swi7 mutants might be a secondary effect of an unstable DNA replication fork.
