Pyrimidine Dimers in the DNA of Paramecium aurelia
Biophysical Journal, 1968 The production and fate of thymine-containing pyrimidine dimers in Paramecium aurelia DNA was investigated in three experimental series: production of dimers by UV irradiation, fate of dimers in the dark, and "loss of photoreactivability of dimers." It is shown that cyclobutyl dimers are made by UV irradiation of Paramecium DNA in vivo, that because of

RAD51 and RAD51 paralog inhibition sensitizes nonreplicating quiescent keratinocytes to UV radiation
Photochemistry and Photobiology, EarlyView.UV radiation and other compounds generate DNA adducts that block transcription and induce cell death if not removed by the nucleotide excision repair system. In this work, we used a small‐scale pharmacological screen to discover that inhibition of the recombinase RAD51 sensitized nonreplicating quiescent keratinocytes to both UVR and other agents that ...

Photoprotective potential of gadusol against ultraviolet B radiation in melanocytes
Photochemistry and Photobiology, EarlyView.Gadusol protects melanocytes from ultraviolet B (UVB)‐induced damage without cytotoxicity. Abstract The increasing incidence of skin cancer, including melanoma, combined with the need for ultraviolet (UV) filters that are safe for human health and marine ecosystems, is driving the search for new photoprotective agents.

2-[(4,6-Diaminopyrimidin-2-yl)sulfanyl]-N-(2-methylphenyl)acetamide
Acta Crystallographica Section E, 2014 In the title compound, C13H15NOS, the plane of the pyrimidine ring makes a dihedral angle of 54.73 (9)° with that of the o-tolyl ring. The molecule adopts an extended conformation, which is evident from the C—C(=O)—N—Car (ar = aromatic) torsion angle of ...

Advanced Science, Volume 13, Issue 14, 9 March 2026.Cytokine‐engineered CAR‐T cells represent a promising immunotherapy against malignancies due to direct tumor killing and potent immunity response. However, significant toxicities, including CRS and ICANS, have restricted clinical applications. How to keep the risk‐benefit balance of the advanced therapy is of great importance for maximizing the benefit
