Biogenic Next‐Gen CPL Emitters: Strategies with Proteins, Polysaccharides, and Nucleotides
Advanced Optical Materials, EarlyView.Biogenic molecules such as proteins, peptides, saccharides, and DNA can act as natural scaffolds for generating circularly polarized luminescence (CPL). This review highlights recent strategies exploiting these inherently chiral frameworks to achieve light emission with controllable handedness under unpolarized excitation, bridging biological ...

Synthetic Routes to N-9 Alkylated 8-Oxoguanines; Weak Inhibitors of the Human DNA Glycosylase OGG1
Molecules, 2015 The human 8-oxoguanine DNA glycosylase OGG1 is involved in base excision repair (BER), one of several DNA repair mechanisms that may counteract the effects of chemo- and radiation therapy for the treatment of cancer. We envisage that potent inhibitors of

Exocytosis from permeabilized bovine adrenal chromaffin cells is differently modulated by guanosine 5'-[gamma-thio]triphosphate and guanosine 5'-[beta gamma-imido]triphosphate [PDF]
, 1992 1. In bovine adrenal chromaffin cells made permeable either to molecules less than or equal to 3 kDa with alphatoxin or to proteins less than or equal to 150 kDa with streptolysin O, the GTP analogues guanosine 5'-[beta gamma-imido]triphosphate (p[NH]ppG)

Control of DNA minor groove width and Fis protein binding by the purine 2-amino group. [PDF]
, 2013 The width of the DNA minor groove varies with sequence and can be a major determinant of DNA shape recognition by proteins. For example, the minor groove within the center of the Fis-DNA complex narrows to about half the mean minor groove width of ...

PRDM16 Reduces Cellular Senescence by Upregulating GSTM1
Advanced Science, EarlyView.Cellular senescence drives aging and aging‐related organ disorders, yet PRDM16's role remains unexplored. This work uncovers that PRDM16 decreases significantly in aged organs, while its loss accelerates cellular senescence and aging‐related organ injury.

Navigating Transition Metal‐Dependent Cell Death: Mechanisms, Crosstalk, and Future Directions
Advanced Science, EarlyView.Transition metals trigger distinct regulated cell death pathways beyond traditional apoptosis. This review examines ferroptosis (iron‐catalyzed lipid peroxidation) and cuproptosis (copper‐induced mitochondrial proteotoxicity), while exploring hypothetical “cobaltosis” as a novel pathway.
