Pyridoxal Reprograms Peroxisomal Hydrogen Peroxide Metabolism to Induce Lethal Oxidative Stress in Ovarian Cancer

open access: yesiMetaMed, EarlyView.
Pyridoxal (PL) exhibits the strongest anti‐tumor activity within the vitamin B6 family, demonstrating significant ovarian cancer cell‐killing efficacy in vivo, in vitro, and in patient‐derived organoid (PDO) models. The anti‐tumor mechanism involves PL inducing a shift in peroxisome dynamics towards fission, promoting peroxisome proliferation, and ...

N6‐Methyladenosine (m6A) in Liver Disease: Pathogenic Mechanisms and Therapeutic Potential

open access: yesiNew Medicine, EarlyView.
ABSTRACT Accumulating evidence highlights the critical role of epigenetic modifications, particularly N6‐methyladenosine (m6A), in liver disease. As the most abundant RNA modification in eukaryotic cells, m6A is dynamically regulated by multicomponent m6A methyltransferases (e.g., METTL3 and METTL14), demethylases (FTO and ALKBH5), and m6A‐binding ...

Peri‐implant hypoxia as a potential barrier against ferroptotic mechanisms during peri‐implant diseases: A cross‐sectional study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Hypoxia modulates inflammation and oxidative stress through hypoxia‐inducible factor‐1α (HIF‐1α). Ferroptosis, an iron‐dependent cell death process, is regulated by glutathione peroxidase‐4 (GPX4) and involves lipid peroxidation markers like malondialdehyde (MDA).

CD8+ T cells sustain antitumor response by mediating crosstalk between adenosine A2A receptor and glutathione/GPX4

open access: yesThe Journal of Clinical Investigation
Antitumor responses of CD8+ T cells are tightly regulated by distinct metabolic fitness. High levels of glutathione (GSH) are observed in the majority of tumors, contributing to cancer progression and treatment resistance in part by preventing ...

Hypoxia‐Induced Histone Lactylation Promotes Ferroptosis in Cardiomyocytes via the Wnt/β‐Catenin Pathway

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study investigated the effects of histone lactylation on ferroptosis in hypoxia‐induced cardiomyocytes. A hypoxia model was established in AC16 cells treated with 2‐Deoxy‐D‐glucose (2‐DG, a glucose analogue), ferrostatin‐1 (Fer‐1, a selective ferroptosis inhibitor), lactate (LA), sh‐β‐catenin (shRNA of β‐catenin), or SKL2001 (an agonist ...

USP54 Promotes Ferroptosis in Non‐Small Cell Lung Cancer by Mediating FOXA2 Deubiquitination and Enhancing ACSL4 Transcription

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Non‐small cell lung cancer (NSCLC) is the most common type of lung cancer, with a 5‐year survival rate of less than 20% and a high risk of recurrence despite advances in treatment. This study aimed to identify new therapeutic targets to increase the effectiveness of NSCLC treatments.

USP7 Regulates TRPV1 Deubiquitination to Mediate Chondrocyte Ferroptosis and Alleviate Osteoarthritis

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Osteoarthritis (OA) is a common degenerative joint disease characterized by chondrocyte dysfunction. In this study, we explored the function and mechanism of ubiquitin‐specific protease 7 (USP7) in chondrocyte ferroptosis in OA. The USP7, TRPV1, collagen II, and GPX4 levels in knee joint tissue were detected using immunohistochemistry ...

Valproic Acid Inhibits Ferroptosis and Improves Bone Integration in OVX Rats Through the AMPK/SIRT1 Pathway

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The prevalence of postmenopausal osteoporosis (PMOP) has been steadily increasing. Ferroptosis has been recognized as a critical factor influencing the bone‐forming ability of bone marrow mesenchymal stem cells (BMSCs). Valproic acid (VPA), an HDAC inhibitor, has been suggested to play a role in regulating osteoporosis development; however ...
