Ac‐SDKP modulates apoptosis via HSP27 and the FAS/FASL and mitochondrial axes

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Schematic diagram of Ac‐SDKP regulating the FAS/FASL and mitochondrial apoptosis pathways via HSP27. Ac‐SDKP inhibits HSP27 expression, activates the FAS/FASL pathway and Caspase‐3 signaling, increases Caspase‐8 and Caspase‐3 expression, and induces cell apoptosis.

Chemical Synthesis and Functional Screening of an 800 000‐Member Library Using a Peptide‐Pairing Strategy

open access: yesAngewandte Chemie, EarlyView.
Chemical peptide synthesis allows the generation of structurally highly diverse compounds suited for ligand development, but current methods in parallel peptide synthesis limit the achievable library size to a few thousand. A strategy is presented based on combinatorial pairing of short peptides via disulfide linkage that enables the generation and ...

A Comprehensive In Vitro Approach for Assessing the Physiological Degradation of Medical Implants: The Silkothane Arteriovenous Graft Case Study

open access: yesAdvanced NanoBiomed Research, EarlyView.
Evaluating the degradation of absorbable medical devices in vitro demands physiologically relevant conditions. This study presents a comprehensive framework applied to a three‐layered silk fibroin/polyurethane arteriovenous graft, employing human enzymes at physiological concentrations over 6 months. Multiparametric analyses of both graft structure and

In Vitro Selection of Functional Neoproteins Containing Highly Fluorinated Cores

open access: yesAngewandte Chemie, EarlyView.
The generation of neoproteins—functional proteins containing unnatural amino acids—is a key goal in synthetic biology. We develop a platform to discover neoproteins with specified bioactivity from trillion‐member sequence libraries, using genetic code reprogramming, in vitro selection and microwave peptide synthesis.

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron

open access: yesAngewandte Chemie, EarlyView.
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage
