Translesion DNA Polymerases [PDF]
Cold Spring Harbor Perspectives in Biology, 2013 Living cells are continually exposed to DNA-damaging agents that threaten their genomic integrity. Although DNA repair processes rapidly target the damaged DNA for repair, some lesions nevertheless persist and block genome duplication by the cell's replicase.

Promutagenicity of 8-Chloroguanine, A Major Inflammation-Induced Halogenated DNA Lesion
Molecules, 2019 Chronic inflammation is closely associated with cancer development. One possible mechanism for inflammation-induced carcinogenesis is DNA damage caused by reactive halogen species, such as hypochlorous acid, which is released by myeloperoxidase to kill ...

Translesion synthesis in mammalian cells [PDF]
, 2006 DNA damage blocks the progression of the replication fork. In order to circumvent the damaged bases, cells employ specialized low stringency DNA polymerases, which are able to carry out translesion synthesis (TLS) past different types of damage. The five

DNA Polymerase Profiling [PDF]
, 2008 We report a simple homogeneous fluorescence assay for quantification of DNA polymerase function in high throughput. The fluorescence signal is generated by the DNA polymerase triggering opening of a molecular beacon extension of the template strand. A resulting distance alteration is reported by fluorescence resonance energy transfer between two dyes ...

Cyclocytidine hydrochloride inhibits the synthesis of relaxed circular DNA of hepatitis B virus [PDF]
PeerJ, 2022 Background Cyclocytidine hydrochloride (HCl) has been reported to inhibit DNA synthesis by affecting DNA polymerase. Here, we tested the antiviral effect of cyclocytidine on hepatitis B virus (HBV) DNA synthesis, which is reliant on DNA polymerase ...

A comparative study of DNA-dependent RNA polymerases from rat ascites hepatoma cell nuclei and from rat liver nuclei [PDF]
, 1975 DNA-dependent RNA polymerases (EC 2.7.7.6) were extracted and partially purified form the nuclei of rat ascites hepatoma cells (AH-130) induced by 4-dimethylaminoazobenzene.

DNA Polymerase e - More Than a Polymerase
The Scientific World Journal, 2003 This paper presents a comprehensive review of the structure and function of DNA polymerase e. Together with DNA polymerases a and d, this enzyme replicates the nuclear DNA in the eukaryotic cell.

A nuclear family A DNA polymerase from Entamoeba histolytica bypasses thymine glycol. [PDF]
PLoS Neglected Tropical Diseases, 2010 BACKGROUND: Eukaryotic family A DNA polymerases are involved in mitochondrial DNA replication or translesion DNA synthesis. Here, we present evidence that the sole family A DNA polymerase from the parasite protozoan E.

P53 tumour-suppressor gene mutations are mainly localised on exon 7 in human primary and metastatic prostate cancer. [PDF]
, 1996 Mutations in the p53 tumour-suppressor gene are among the most common genetic alterations in human cancers. In the present study we analysed the mutations in the p53 tumor-suppressor gene in 25 primary and 20 metastatic human prostate cancer specimens ...

Engineering processive DNA polymerases with maximum benefit and minimum cost
Frontiers in Microbiology, 2014 DNA polymerases need to be engineered to achieve optimal performance for biotechnological applications, which often require high fidelity replication when using modified nucleotides and when replicating difficult DNA sequences.
