Transcription-coupled DNA repair: two decades of progress and surprises
TLDR
Finite cycles of TCR at naturally occurring non-canonical DNA structures might contribute to genomic instability and genetic disease.
Comparative gene expression profiles following UV exposure in wild-type and SOS-deficient Escherichia coli.
TLDR
The time courses of expression of the genes surrounding the 26 documented lexA-regulated regions on the E. coli chromosome are reported here and several newly identified UV-responsive genes are discussed with respect to their possible roles in cellular recovery following exposure to UV irradiation.
Expression of the p48 xeroderma pigmentosum gene is p53-dependent and is involved in global genomic repair.
TLDR
It is shown that p48 mRNA levels strongly depend on basal p53 expression and increase further after DNA damage in a p53-dependent manner, and this results identify p48 as the link between p53 and the nucleotide excision repair apparatus.
Evolution of the SNF2 family of proteins: subfamilies with distinct sequences and functions.
TLDR
This work has divided the SNF2 family into multiple subfamilies, each of which represents what it proposes to be a functionally and evolutionarily distinct group, and used the subfamily structure to predict the functions of some of the uncharacterized proteins in the SNf2 family.
Subpathways of nucleotide excision repair and their regulation
TLDR
Since rodents are used as surrogates for environmental cancer risk assessment, it is essential that it is understood how they differ from humans with respect to DNA repair and oncogenic responses to environmental genotoxins.
p53-Mediated DNA Repair Responses to UV Radiation: Studies of Mouse Cells Lacking p53, p21, and/orgadd45 Genes
TLDR
Evidence is provided that Gadd45 affects chromatin remodelling of templates concurrent with DNA repair, thus indicating that gadd45 may participate in the coupling between chromatin assembly and DNA repair.
