The role of endogenous and exogenous DNA damage and mutagenesis.

چکیده
The field of DNA damage responsiveness in general, and the consequences of endogenous and exogenous base damage in DNA, in particular, has made new and exciting contributions to our increasing understanding of the initiation and progression of neoplasia in humans. This article presents some of the highlights in this area of investigation, with a particular emphasis on DNA repair, the tolerance of DNA damage and its contribution to mutagenesis, and DNA damage checkpoint regulation.

Role of Endogenous Development in Informal Habitation: An Analytical Study
Today, most of the big cities or metropolises around the world have been encountering with the problem of informal habitation. The present study, thus, tries to focus on the role of endogenous development in such type of habitation process. For that matter, the paper takes into account architectural programming and urbanism as its theoretical framework because the endogenous development is rela...
متن کاملThe Role of Long Non Coding RNAs in the Repair of DNA Double Strand Breaks
DNA double strand breaks (DSBs) are abrasions caused in both strands of the DNA duplex following exposure to both exogenous and endogenous conditions. Such abrasions have deleterious effect in cells leading to genome rearrangements and cell death. A number of repair systems including homologous recombination (HR) and non-homologous end-joining (NHEJ) have been evolved to minimize the fatal effe...

Arecoline (ARC), an alkaloid of the betel nut (Areca catechu), is a major ingredient of betel quid. The carcinogenic potentiality as well as its cell transformation ability has already been reported. Reduced glutathione (GSH), a major non-protein thiol substance plays an important role in protection of cells against the toxic effect of exogenous compounds. In order to understand the role of fac...
متن کاملGenetic and environmental influence on DNA strand break repair: a twin study.
Accumulation of DNA damage deriving from exogenous and endogenous sources has significant consequences for cellular survival, and is implicated in aging, cancer, and neurological diseases. Different DNA repair pathways have evolved in order to maintain genomic stability. Genetic and environmental factors are likely to influence DNA repair capacity. In order to gain more insight into the genetic...
متن کاملStudy of the association FokI polymorphisms of the XRCC3 gene with the risk of breast cancer in women: brief report
Background: Breast cancer is one of the most common worldwide malignancies among women. Biological data suggest that damage induced by endogenous and exogenous factors affects the integrity of DNA and associated with susceptibility to breast cancer. Single nucleotide polymorphisms (SNPs) in DNA repair genes can associated with differences in the repair efficiency of DNA damage and may affect br...
