Natural product based inhibitors of the thioredoxin–thioredoxin reductase system

Org. Biomol. Chem., 2004
Spiroketal naphthodecalins are readily assembled by Barton's base mediated Ullmann binaphthyl ether coupling, Dakin reactions and hypervalent iodine spirocyclization. The core structures can be further diversified by enone addition and Stille coupling reactions.

Glutathionylation of human thioredoxin: A possible crosstalk between the glutathione and thioredoxin systems [PDF]

Proceedings of the National Academy of Sciences, 2002
To identify proteins undergoing glutathionylation (formation of protein-glutathione mixed disulfides) in human T cell blasts, we radiolabeled the glutathione pool with 35 S, exposed cells to the oxidant diamide, and analyzed cellular proteins by two-dimensional electrophoresis.

A multi-centre study on the role of the thioredoxin system in breast cancer cell proliferation

Бюллетень сибирской медицины, 2018
Redox proteins (thioredoxin, glutaredoxin) are key macromolecules capable of modulating intracellular processes. This determines research choices in the field of redox-dependent cell proliferation management.

Crystal structure of plasmoredoxin, a redox-active protein unique for malaria parasites

Current Research in Structural Biology, 2022
Plasmoredoxin is a 22 ​kDa thiol–disulfide oxidoreductase involved in cellular redox regulatory processes and antioxidant defense. The 1.6 ​Å structure of the protein, solved via X-ray crystallography, adopts a modified thioredoxin fold.

Reprogramming Antitumor Immunity: NK Cell Strategies to Navigate the Immunosuppressive Tumor Microenvironment

Advanced Science, EarlyView.
ABSTRACT Tumor immune escape is a major barrier to durable cancer immunotherapy, as advanced malignancies create a tumor microenvironment (TME) that preferentially exhausts and disables T cell responses. While most approved cell therapies are T cell‐based, this limitation motivates the exploration of an alternative effector cell platform.

PIEZO1 is Required for Acute Myeloid Leukemia Progression and Leukemia Stem Cell Maintenance via HIF1A‐SLC7A11 Axis‐Mediated Ferroptosis Defense

Advanced Science, EarlyView.
This study identifies the mechanosensor PIEZO1 as a key factor in promoting acute myeloid leukemia progression and uncovers a ferroptosis defense system mediated by PIEZO1‐HIF1A‐SLC7A11 axis that is essential for leukemia stem cell maintenance. This ferroptotic defense system may represent a unique vulnerability for leukemia stem cells, providing a ...

PANX2 Suppresses Lung Adenocarcinoma Progression by Inducing Disulfidptosis and Enhancing Antitumor Immunity

Advanced Science, EarlyView.
ABSTRACT Lung adenocarcinoma (LUAD) remains a leading cause of cancer mortality with limited therapeutic options. Disulfidptosis, a novel cell death modality driven by disulfide stress, represents a promising target, yet its regulation in LUAD is poorly defined. Here, we identify Pannexin 2 (PANX2) as a tumor suppressor in LUAD.

PDIA6–SCD1 Axis Rewires Lipid Metabolism to Drive Gastric Cancer Progression

Advanced Science, EarlyView.
Protein disulfide isomerase A6 (PDIA6) is identified as an oncogenic driver in gastric cancer. PDIA6 directly binds and stabilizes SCD1 by limiting its ubiquitin–proteasome‐mediated degradation, thereby sustaining monounsaturated fatty acid (MUFA)‐enriched lipid homeostasis and lipid metabolic reprogramming.

Structure and Function Analyses of the Thioredoxin 2 and Thioredoxin Reductase Gene in Pacific White Shrimp (Litopenaeus vannamei)

Animals
The thioredoxin (Trx) system is one of the most significant systems in living organisms as it regulates cellular redox reactions and plays a pivotal protective role within the cell by promoting redox homeostasis.

Exploring the Diversity of the Thioredoxin Systems in Cyanobacteria

Antioxidants, 2022
Cyanobacteria evolved the ability to perform oxygenic photosynthesis using light energy to reduce CO2 from electrons extracted from water and form nutrients. These organisms also developed light-dependent redox regulation through the Trx system, formed by thioredoxins (Trxs) and thioredoxin reductases (TRs).
