Background: In the fifth National Wilms Tumor Study, patients received vincristine and dactinomycin (VA) without radiation for stage I focal anaplastic Wilms tumor (FAWT) and VA plus doxorubicin (DD4A) and radiation for stage II-IV FAWT. Four-year event-free survival (EFS) and overall survival (OS) for stage I FAWT were 67.5% and 88.

The Mutographs Cancer Grand Challenge team aimed to discover unknown causes of cancer through mutational epidemiology, an alliance of cancer epidemiology and somatic genomics. By generating whole-genome sequences from thousands of cancers and normal tissues from more than 30 countries on five continents, it discovered unsuspected mutagenic exposures affecting millions of people, raised the possibility that some carcinogens act by altering forces of selection in tissue microenvironments rather than by mutagenesis, and demonstrated changes to the direction of somatic evolution in normal cells of the human body in response to exogenous exposures and noncancer diseases.

Imidacloprid (IMI), as an emerging pollutant, is frequently detected in pesticide wastewater. Cobalt-based single-atom catalysts (Co-SACs) doped with sulfur atoms can serve as an efficient strategy to activate peroxymonosulfate (PMS) and degrade organic pollutants. The paper employed density functional theory and computational toxicology to deeply explore the mechanism and ecotoxicity of IMI when S atoms were introduced into Co-SACs for PMS activation.

Altered DNA dynamics at lesion sites are implicated in how DNA repair proteins sense damage within genomic DNA. Using laser temperature-jump (T-jump) spectroscopy combined with cytosine-analog Förster Resonance Energy Transfer (FRET) probes that sense local DNA conformations, we measured the intrinsic dynamics of DNA containing 3 base-pair mismatches recognized in vitro by Rad4 (yeast ortholog of XPC). Rad4/XPC recognizes diverse lesions from environmental mutagens and initiates nucleotide excision repair.
