DDX21 Promotes Breast Cancer Growth and Metastasis via Stimulating RNAPII Elongation During Hypoxia

open access: yesMedComm, Volume 7, Issue 7, July 2026.
DDX21 triggers CDK9 release from the 7SK RNP complex. DDX21‐CDK9 binding to HIFs drives transcriptional reprogramming during hypoxia. DDX21 enhances breast cancer progression and metastasis. Elevated DDX21 expression correlates with poor prognosis in breast cancer patients.

Ischemia–Reperfusion Injury: Molecular Mechanisms and Therapeutic Interventions

open access: yesMedComm, Volume 7, Issue 7, July 2026.
Multiorgan ischemia–reperfusion injury begins with ischemia‐induced ATP depletion and ionic imbalance, followed by reperfusion‐triggered mitochondrial ROS/RNS bursts, regulated cell death, and DAMP release. Sterile inflammation converges on endothelial–immune–coagulation crosstalk, where NETs drive immunothrombosis, no‐reflow, and remote organ injury ...

Drugs that act on both G protein‐coupled receptors (GPCRs) and kinases: potentiation of effects, side effects and general aspects of drug pleiotropy

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 13, Page 3471-3483, July 2026.
Abstract Background A drug designed for a specific target often interacts with multiple targets, either unintentionally or as part of its intended mechanism of action. This has been called pharmacological pleiotropy or polypharmacology. There are key endogenous ligands such as ATP, GABA and glutamate that act on various proteins in humans. Furthermore,

Representations of Nonlocal Syntactic Dependencies Feed Verb Learning in Infancy

open access: yesDevelopmental Science, Volume 29, Issue 4, July 2026.
ABSTRACT The ability to represent both local and nonlocal syntactic dependencies emerges in an infant's second year of life, raising questions about how these early syntactic representations interact with language learning in other domains. Using wh‐questions as our case study, we investigate how infants’ syntactic dependency acquisition interacts with

Crystal Structure and Conformational Dynamics of N─N Bond‐Forming Piperazate Synthase

open access: yesChemBioChem, Volume 27, Issue 12, 26 June 2026.
Piperazate synthases (PZSs) catalyze the key N─N bond formation in the biosynthesis of the rare amino acid piperazic acid. X‐ray crystal structures of apo‐ and holo‐SbPZS show a dimeric enzyme with two heme‐containing active sites, where histidine residues coordinate the iron centers.

Nickel Photocatalytic Access to β‐Arylated β‐Amino Acids

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
Converting naturally abundant amino acids to non‐canonical derivatives in one step under mild conditions allows for improved pharmaceutical properties. Now, this is achieved for β‐arylated β‐amino acids, which are available in good yields directly from aspartic acid, and have the potential to become platform chemicals for drug discovery.

Substrate Specificity of B12‐Depedent Ribonucleotide Reductases: Biotechnology and Metabolic Implications

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
Ribonucleotide reductases (RNRs) are valuable biocatalysts for the biosynthesis of non‐natural deoxyribonucleotide, relevant in fields like medical science and synthetic biology. In this study, we explore the substrate spectrum of two thermostable RNRs and discuss their implications for nucleotide metabolism and biocatalytical applications ...

HaloTag Fusion Enables Dynamic Analysis of Prion Protein Biosynthesis, Turnover, and Misfolding

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
Prion protein (PrP) misfolding underlies fatal neurodegenerative diseases. We developed a HaloTag‐based PrP fusion enabling spatiotemporal labeling of distinct PrP populations in living cells. This system recapitulates native PrP biology, reveals early misfolding events in disease‐associated mutants, and allows mechanistic interrogation of PrP‐lowering

Kinetic Fingerprints as Mechanistic and Clinical Roadmaps Across KIT Activation States

open access: yesChemMedChem, Volume 21, Issue 11, 15 June 2026.
Kinetic profiling of 172 compounds across KIT conformations—including D816V—reveals kinetic fingerprints that predict efficacy, selectivity, resistance, and inhibitors’ ability to stabilize key regulatory elements. Far from a secondary metric, binding kinetics provide mechanistic insights beyond affinity, offering a powerful framework for rational drug

Nano‐Gs Protein Peptidomimetics: Rational Design of Gα C‐Terminus‐Derived Peptides Mimicking Key Components of Gs‐β2AR Interactions

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 24, 8 June 2026.
G protein‐coupled receptors (GPCRs) are major therapeutic targets. Modulating GPCR activity through intracellular sites is evolving. A structure‐ and computation‐assisted approach generated small G protein‐derived peptidomimetics targeting the intracellular binding crevice of the β2 adrenergic receptor mimicking features of the full G protein.
