Proteogenomic characterization of cholangiocarcinoma
Hepatology, EarlyView., 2022 Proteogenomic characterization of cholangiocarcinoma with therapeutic strategies Abstract Background and Aims Cholangiocarcinoma (CCA) is a highly heterogeneous cancer with limited understanding and few effective therapeutic approaches. We aimed at providing a proteogenomic CCA characterization to inform biological processes and treatment ...

An IscS Persulfide Donates the Sulfur for Ribosomal Protein uL16 Thioamidation
Angewandte Chemie, EarlyView.YcaO‐catalyzed thioamidation of the ribosomal subunit protein uL16 is widespread in Pseudomonadota bacteria. We identify the iron–sulfur cluster cysteine desulfurase IscS as the sulfur donor via an IscS persulfide and observe direct IscS–uL16 interactions.

Purine Nucleotide Availability Regulates mTORC1 Activity through the Rheb GTPase.
Cell Reports, 2017 Pharmacologic agents that interfere with nucleotide metabolism constitute an important class of anticancer agents. Recent studies have demonstrated that mTOR complex 1 (mTORC1) inhibitors suppress de novo biosynthesis of pyrimidine and purine nucleotides.

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism
Advanced Science, EarlyView.Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

Angewandte Chemie, EarlyView.Our study investigates macromolecular crowding effects in the Arrhenius‐like and non‐Arrhenius temperature regimes of the human platelet isoform of phosphofructokinase‐1 (PFKP). The results reveal how PFKP maintains temperature robustness of catalytic activity in differently crowded environments.

Advanced Science, EarlyView.Chemical switching of OGG1 by CMM‐98 accelerates oxidative DNA damage repair and enhances hepatocyte resilience during acetaminophen‐induced acute liver injury. By promoting efficient processing of OGG1‐generated repair intermediates, CMM‐98 reduces oxidative damage, preserves cellular integrity, and protects against acute liver failure, identifying ...

Angewandte Chemie, EarlyView.Multiphase DNA–RNA artificial cells integrate a protective DNA shell, a transcriptionally active DNA core, and a functional RNA organelle. Spatial compartmentalization enables signal generation, external protein expression, and selective recapture via RNA aptamers. ABSTRACT Naturally occurring biomolecular condensates orchestrate key cellular processes

Influence of Purine on Brass Behavior in Neutral and Alkaline Sulphate Solutions
International Journal of Electrochemical Science, 2012 The behavior of Cu37Zn brass in the presence of purine in the wide concentration range (1·10-6mol/dm3-1·10-2mol/dm3) in a neutral and weakly alkaline 0.5mol/dm3 Na2SO4 solution is studied using potentiodynamic polarization and chronoamperometry ...
