Targeting the NR3C1‐ACSL4 Axis Triggers Ferroptosis to Overcome Radioresistance in Prostate Cancer

Cancer Science, EarlyView.
The glucocorticoid receptor NR3C1 drives prostate cancer radioresistance by upregulating ACSL4. High ACSL4 levels create a lipid metabolic vulnerability. The clinical agent DHA synergizes with ACSL4 to induce lipid peroxidation and ferroptosis, effectively overcoming radioresistance.

SCD2 Alleviates Diabetes‐Associated Cognitive Dysfunction by Improving Microglial Lipid Metabolism

Cell Proliferation, EarlyView.
This study reveals a novel mechanism of microglial metabolic dysfunction in diabetic cognitive impairment. Defective SCD2 disrupts monounsaturated fatty acid (MUFA) metabolism, triggering mitochondrial oxidative phosphorylation dysfunction and leading to abnormal lipid droplet accumulation (marked by PLIN2).

PLIN5 Protects Against Ang II‐Induced Podocyte Lipotoxicity by Interacting With FKBP8 and Preserving Lipid Droplet–Mitochondria Contact

Cell Proliferation, EarlyView.
PLIN5‐FKBP8 tethers lipid droplets to mitochondria to counteract Ang II‐induced lipotoxicity. ABSTRACT Chronic kidney disease (CKD) remains a major global health challenge. Angiotensin II (Ang II)‐induced lipotoxicity is an important contributor to podocyte injury.

Macrophage Lipid Homeostasis Drives IVDD via a Senescence‐Dependent Impairment of Efferocytosis

Cell Proliferation, EarlyView.
Intervertebral disc degeneration (IVDD) has been a leading cause of low back pain and lacks disease‐modifying therapies. Although dysregulated disc lipid metabolism is implicated, its impact on the immune microenvironment, particularly macrophages, remains unknown.

Disruption of iron metabolism resulting from Dmt1/Slc11a2 deficiency compromises Notch protein degradation and transcriptional activation

The FEBS Journal, EarlyView.
Divalent metal transporter 1 (Dmt1) maintains iron homeostasis and lysosomal proteostasis required for physiological Notch receptor–ligand signaling. Dmt1 loss lowers iron storage capacity (ferritin), increasing intracellular Fe2+, driving ROS and lipid peroxidation, and leading to lysosomal/mitochondrial dysfunction.

Compromised DNA replication in gut cells underlies sensitivity to genotoxic stress in the tardigrade Hypsibius exemplaris

The FEBS Journal, EarlyView.
DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...
