Selective Inhibition of Protein Disulfide Isomerase by Estrogens

Journal of Biological Chemistry, 1989
Protein disulfide isomerase (PDI) is a multifunctional microsomal enzyme that participates in the formation of protein disulfide bonds. PDI catalyzes the reduction of protein disulfide bonds in the presence of excess reduced glutathione and has been implicated in the reductive degradation of insulin; E.

An Overview of Liquid Chromatography–Mass Spectrometry (LC–MS) Methods for the Quantification of Antibody‐Drug Conjugates

Biomedical Chromatography, Volume 40, Issue 2, February 2026.
ABSTRACT Antibody‐drug conjugates (ADCs) are innovative drugs composed of cytotoxic molecules (payload) linked to antibodies, that selectively target and kill cancer cells upon internalization. In vivo, ADCs exist as intact molecules, naked antibodies, or released, unconjugated (linker‐)payload.

CRISPR‐Cas9‐Generated TXNDC15 c.560delA Homozygous Mouse Model Exhibits Meckel–Gruber Syndrome Phenotype

genesis, Volume 64, Issue 1, February 2026.
ABSTRACT To determine whether TXNDC15 variation causes Meckel–Gruber syndrome (MKS), we assessed the pathogenicity of the frameshift variant c.560delA. A CRISPR–Cas9 generated mouse model carrying the equivalent Txndc15 c.512delA mutation was analyzed at embryonic day 15.5.

Proteomic Analysis of Regulated Dendritic Cell Endosomes Reveals Dynamic Adaptation to Antigen Uptake and Cross‐Presentation

European Journal of Immunology, Volume 56, Issue 2, February 2026.
Phagocytosis of yeast activates recruitment of proteases and trafficking factors from the secretory and endosomal pathways to the IRAP compartment and subsequently phagosomes, promoting cross‐presentation. In the absence of Sec22b, IRAP endosome and phagosome maturation to late endosomes is accelerated.

Oxidative Stress: Molecular Mechanisms, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 2, February 2026.
Oxidative stress occurs when the reactive oxygen species (ROS) production overwhelms the ROS scavenging, which lead to genomic instability, epigenetic regulation, proteostasis imbalance, and lipid peroxidation, subsequently causing the occurrence and development of numerous diseases. ABSTRACT Although the physiological level of reactive oxygen species (

Manipulation of the Unfolded Protein Response by Intracellular Bacterial Pathogens: Mechanisms of ER Hijacking and Therapeutic Implications

The FASEB Journal, Volume 40, Issue 2, 31 January 2026.
This review illustrates how intracellular bacterial pathogens—such as Brucella, Mycobacterium tuberculosis, and Legionella—secrete effector proteins that specifically target the IRE1α, PERK, and ATF6 branches of the unfolded protein response (UPR) to hijack ER stress signaling.

Protein disulfide isomerase-9 interacts with the lumenal region of the transmembrane endoplasmic reticulum stress sensor kinase, IRE1, to modulate the unfolded protein response in Arabidopsis

Frontiers in Plant Science
Environmental stressors disrupt secretory protein folding and proteostasis in the endoplasmic reticulum (ER), leading to ER stress. The unfolded protein response (UPR) senses ER stress and restores proteostasis by increasing the expression of ER-resident

Meloidogyne graminicola protein disulfide isomerase may be a nematode effector and is involved in protection against oxidative damage

Scientific Reports, 2019
The rice root-knot nematode, Meloidogyne graminicola, is a serious pest in most rice-growing countries. Usually, nematodes employ antioxidants to counteract the harm of reactive oxygen species (ROS) and facilitate their infection.

Isoquercetin and Zafirlukast Cooperatively Suppress Tumor Growth and Thromboinflammatory Signaling in a Xenograft Model of Ovarian Cancer

The FASEB Journal, Volume 40, Issue 1, 15 January 2026.
Treatment using either the thiol isomerase inhibitor isoquercetin or zafirlukast lowers tissue factor levels, decreases VEGF, inhibits PD‐L1, and TMEM176B in a xenograft model of ovarian cancer. A combination of the two agents, at threefold lower concentrations than either drug, significantly enhanced the inhibition further, suggesting a dual action of

Asparagine614 Determines the Transport and Function of the Murine Anti-Aging Protein Klotho

Cells
Klotho is an anti-aging protein whose deletion significantly reduces lifespan in mice, while its over-expression increases lifespan. Klotho is a type-I transmembrane protein that is N-glycosylated at eight positions within its ectodomain.
