Controlling platinum, ruthenium, and osmium reactivity for anticancer drug design [PDF]
The main task of the medicinal chemist is to design molecules that interact specifically with derailed or degenerating processes in a diseased organism, translating the available knowledge of pathobiochemical and physiological data into chemically ...

IncRNA‐ZFAS1, an Emerging Gate‐Keeper in DNA Damage‐Dependent Transcriptional Regulation
LncZFAS1 plays a crucial role during DNA damage response in mammalian cells. Loss of lncZFAS1 results in deficient DNA lesion removal and reduced cell viability. Mechanistically, lncZFAS1 modulates RNAPII phosphorylation and transcription and thereby promotes both GG‐NER and TC‐NER upon UV damage.

Evidence for a Rad18-independent frameshift mutagenesis pathway in human cell-free extracts. [PDF]
Bypass of replication blocks by specialized DNA polymerases is crucial for cell survival but may promote mutagenesis and genome instability. To gain insight into mutagenic sub-pathways that coexist in mammalian cells, we examined N-2-acetylaminofluorene (

Exploitation of proteomics strategies in protein structure-function studies [PDF]
Mass spectrometry plays a central role in structural proteomics, particularly in highly intensive structural genomics projects. This review paper reports some examples taken from recent work from the authors' laboratory and is aimed at showing that modem

DNA adducts as a dosimeter for risk estimation.
The dose response for O6-methylguanine (O6MG) formation and cytotoxicity was determined in lung and nasal mucosa from Fischer 344 rats during multiple dose administration of the tobacco-specific nitrosamine-4-(N-methyl-N-nitrosamino)-1-(3-pyridyl)-1-butanone (NNK).

The most frequent DNA adduct made by the anticancer drug cisplatin, the 1,2-intrastrand d(GpG) cross-link, as well as the minor 1,3-intrastrand d(GpTpG) adduct, were both repaired by an in vitro human excision repair system.

The bottom‐up strategy based on multiomics data is used for the SynCom design, and it successfully inhibited F. nucleatum growth and achieved stable colonization in vivo. In addition, it promoted tryptophan metabolism and secondary bile acid conversion, reduced lipid accumulation, relieved microbiome disorder, decreased inflammatory reaction, and ...

Dehydroepiandrosterone modulates oxidative DNA damage in pancreatic cancer: A case–control study
Background and Aim Dehydroepiandrosterone (DHEA) has a protective role against several types of cancer, although its mechanisms of action are still unknown, it may be related to the antioxidant effect of DHEA.

This study establishes a diesel engine exhaust (DEE)‐induced malignant transformation model in bronchial epithelial cells. Whole genome sequencing(WGS) and RNA‐seq reveal DEE‐induced mutational signatures and gene expression profiles. Mechanistically, DEEaffect polymerase epsilon (POLE) and mismatch repair, driving genomic instability and promoting ...
