Characterization of a Fungal Modular Polyketide Synthase System Reveals an Unusual Strategy for Polyketide Chain Initiation

open access: yesAngewandte Chemie, EarlyView.
Fungal modular polyketide synthases (PKSs) remain largely unexplored. Functional characterization of the LasC/LasD assembly line established its role in strasseriolide C biosynthesis and suggested an unexpected strategy for chain initiation, in which a malonyl unit is transferred from the module 2 acyl carrier protein (ACP) domains to the loading ACP ...

Topical Losartan Treatment of Herpes Simplex Virus- or Varicella-Zoster Virus-Induced Corneal Scarring: A Case Series

open access: yesCase Reports in Ophthalmology
Introduction: Topical losartan has emerged as a promising therapeutic option for preventing and treating corneal scarring fibrosis. Its mechanism of action involves the inhibition of ERK-mediated signaling in the noncanonical TGF-beta pathways,

Phosphorylation of N-glycans in the brain: The case for a non-canonical pathway?

open access: yesBBA Advances
Asparagine-linked glycosylation (N-glycosylation) is a common co- and post-translational modification that refers to the addition of complex carbohydrates, called N-linked glycans (N-glycans), to asparagine residues within defined sequons of polypeptide ...

Isocitrate Dehydrogenase-Mutant WHO Grade 4 Astrocytoma with BCOR Alteration: Case Report

open access: yesCase Reports in Oncology
Introduction: BCOR, a transcriptional regulator and component of the noncanonical polycomb repressive complex 1 (PRC1), plays an important role in tumorigenesis through transcriptional repression mediated by histone modifications.

Beyond Nature's Blueprint: Macrocyclic Peptides Containing Unnatural Amino Acids in Therapeutic Development

open access: yesAngewandte Chemie, EarlyView.
Strategic incorporation of unnatural amino acids transforms macrocyclic peptides into drug‐like molecules capable of engaging challenging targets. These building blocks enhance stability, permeability, and bioavailability, accelerating the development of next‐generation peptide therapeutics.

A germline JAK2 exon12 mutation and a late somatic CALR mutation in a patient with essential thrombocythemia

open access: yesFrontiers in Oncology
BackgroundIt has been discovered that Janus kinase 2 (JAK2) exon12 mutations lead to the polycythemia vera (PV) phenotype, while somatic mutations of calreticulin (CALR) are associated with essential thrombocythemia (ET) or primary myelofibrosis. In this

Preserving ester-linked modifications reveals glutamate and aspartate mono-ADP-ribosylation by PARP1 and its reversal by PARG

open access: yesNature Communications
Ester-linked post-translational modifications, including serine and threonine ubiquitination, have gained recognition as important cellular signals. However, their detection remains a significant challenge due to the chemical lability of the ester bond ...

Thinking Outside the Binding Site: A Self‐Encapsulating Kinase Inhibitor Remodels Its Pocket to Achieve Selectivity

open access: yesAngewandte Chemie International Edition, EarlyView.
To make exceptionally effective drugs, thinking “outside the binding site” is required. This work reveals that counterintuitive targeting of a kinase‐conserved region can lead to highly selective binding. Inhibitor discovery coupled to x‐ray crystallography shows that a network of noncanonical interactions and long‐range effects of distant unique amino

Increased Plasma Microbial tDR‐1 in At‐Risk Individuals Is Associated With Decreased Conversion to Clinical Rheumatoid Arthritis and Reduces an In Vitro Macrophage Type 1 Interferon Response

open access: yesArthritis &Rheumatology, EarlyView.
Objective Microbial small RNAs can regulate human genes. Higher plasma concentrations of microbial transfer RNA (tRNA)‐derived RNA‐1 (tDR‐1) were previously associated with lower rheumatoid arthritis (RA) disease activity. This study examined whether tDR‐1 concentrations differ in anticyclic citrullinated peptide‐3 positive (CCP3+) at‐risk individuals (
