HNRNPU K181 Lactylation Drives Cervical Cancer Growth by Upregulating PHGDH and Reprogramming Serine Metabolism

open access: yesAdvanced Science, EarlyView.
Lactate in cervical cancer induces HNRNPU K181 lactylation, opposed by NAA50‐mediated acetylation and suppressed by Pazopanib. This lactylation enhances HNRNPU binding to PHGDH pre‐mRNA exon 1, maintaining exon 1‐containing transcripts and mRNA stability, thereby activating serine metabolism.

New Water Oxidation Mechanism in Photosystem II Resolves Major Experimental Controversies

open access: yesAngewandte Chemie, EarlyView.
In Photosystem II Oxygen Evolving Complex, we discovered the O3‐O6 peroxide at lower energy. Assignment of the O3 ligated by histidine (His337) as a slow exchanging substrate and its coupling with O6 give the O─O bond formation mechanism most consistent with all currently available experimental data. Proposal shows how protein environment can steer the

Cysteine Thioaldehydes: Photolytic Generation, Reactivity, and Biological Implications

open access: yesAngewandte Chemie, EarlyView.
Photolysis of cysteine phenacylsulfides bearing non‐conjugating electron‐withdrawing substituents leads to high conversions into cysteine thioaldehydes through a Norrish type‐II pathway. This methodology enabled the study of the aqueous reactivity of these important biosynthetic intermediates, which, depending on peptide sequence, pH and buffer ...

UFL1‐Mediated UFMylation of ENO1 Restrains Aerobic Glycolysis and Colorectal Cancer Progression

open access: yesAdvanced Science, EarlyView.
UFMylation restrains aerobic glycolysis and colorectal cancer progression by modifying the glycolytic enzyme ENO1. Pharmacological enhancement of the UFL1–ENO1 interaction by the FDA‐approved antibiotic torezolid promotes ENO1 UFMylation, suppresses tumor metabolism, and sensitizes colorectal cancer to chemotherapy, revealing an actionable metabolic ...

Enhancement of Dissymmetry Factors Through Axial Elongation of Hetero[n]helicenes

open access: yesAngewandte Chemie, EarlyView.
A benzofuran scaffolding strategy enables the synthesis of hetero[9]‐, [12]‐, and [15]helicenes. Structural and chiroptical analyses demonstrate that systematic axial elongation increases helical distortion and significantly amplifies luminescence dissymmetry.
