LKB1 Loss Sensitizes Lung Tumor Spheres to Mitomet‐Induced Ferroptosis, and These Effects are Enhanced by mTOR Inhibition

open access: yesMolecular Carcinogenesis, EarlyView.
ABSTRACT Owing to their robust antioxidant defense mechanisms, cancer stem‐like cells (CSCs) maintain a low level of oxidative stress, which is crucial for preserving stemness and pluripotency. Therefore, agents that either directly generate reactive oxygen species (ROS) or inhibit the antioxidant defense systems can selectively induce oxidative cell ...

Elevation of Stearoyl‐Coenzyme A Desaturase and Monounsaturated Fatty Acids in Parkinson's Disease Serum

open access: yesMovement Disorders, EarlyView.
Abstract Background Emerging evidence indicates that dysregulation of monounsaturated fatty acids (MUFAs), synthesized by the enzyme stearoyl‐coenzyme A desaturase (SCD), impacts on α‐synuclein pathology in the Parkinson's disease (PD) brain. Objective The objective of this study was to analyze SCD and MUFA‐enriched lipids in the periphery of patients ...

Ferroptosis and Its Emerging Role in Gestational Diabetes Mellitus

open access: yesMedicine Advances, EarlyView.
Ferroptosis contributes to the development of gestational diabetes mellitus (GDM) through iron overload, lipid peroxidation, and antioxidant system disruption. These changes impair adipocyte and β‐cell function, promoting insulin resistance and hyperglycemia.

On the Origin of the Brain Semi‐Heavy Water Deuterium MR Signal Following Administration of Deuterated Metabolic Substrate: A Cautionary Tale

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate the extent to which the appearance of HOD in the brain following systemic administration of a deuterated substrate is due to local brain metabolism versus body metabolism. Methods [6,6‐2H2]glucose, which is transported across the blood‐brain barrier (BBB), and [6,6‐2H2]fructose (Fruc), which does not cross the BBB, were ...

Quantitative Imaging of Pyruvate Metabolism in a Patient With Anaplastic Thyroid Cancer

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Magnetic resonance imaging using hyperpolarized (HP) [1‐13C]‐pyruvate enables assessment of pyruvate metabolism in vivo and offers new insight into metabolic changes in response to cancer therapy. Widely used semi‐quantitative metrics of pyruvate metabolism can be affected by physiological factors that are extrinsic to intracellular ...

Alterations in Metabolites Associated With Umbilical Cord Blood in Monozygotic Twins Discordant for Congenital Heart Disease

open access: yesPediatric Discovery, EarlyView.
This study found that the metabolomic signature of umbilical venous cord blood in congenital heart disease (CHD) differs from that of healthy monozygotic (MZ) co‐twins. Dysregulation of metabolic pathways like glucose, lipid, and amino acid metabolism, along with altered metabolites, helps understand CHD predisposition.
