Senkyunolide I Inhibits mtDNA‐cGAS‐STING Signaling in Macrophages via Targeting VDAC1 Oligomerization to Attenuate Ulcerative Colitis

Advanced Science, EarlyView.
In macrophages, senkyunolide I (SEI) directly targets the K12 residue of VDAC1 to inhibit its stress‐induced oligomerization, a critical upstream event that effectively prevents mitochondrial DNA release and subsequent cGAS‐STING pathway activation.

Ferroptosis Suppression by the M6A Reader IGF2BP1 Underlies Gemcitabine Resistance in Pancreatic Ductal Adenocarcinoma

Advanced Science, EarlyView.
IGF2BP1 promotes gemcitabine resistance in pancreatic cancer by stabilizing m6A‐modified FTH1 transcripts and protecting them in stress granules, thereby suppressing ferroptosis. Pharmacological inhibition of IGF2BP1 disrupts this protective pathway, restores ferroptotic sensitivity, and enhances gemcitabine efficacy in resistant tumors.

m6A‐Driven Pexophagy Triggers Placental Ferroptosis to Impair Fetal Growth Upon Environmental Stress

Advanced Science, EarlyView.
Prenatal environmental stress exposure promotes m6A modification to drive PEX2‐dependent pexophagy, thereby causing placental ferroptosis and FGR. ABSTRACT The role and underlying mechanisms of placental ferroptosis in fetal growth restriction (FGR) induced by environmental stress remain poorly understood.

Kidney‐Targeted Cilastatin Nanoparticles Inhibit DPEP1‐Mediated Ferroptosis for Acute Kidney Injury Therapy

Advanced Science, EarlyView.
In this study, MPDA NPs were engineered to encapsulate CTT. To further increase renal accumulation of CTT, L‐serine was conjugated to the surface of the MPDA nanoparticles (CTT/MPDA@L‐Ser NPs). CTT/MPDA@L‐Ser NPs inhibit DPEP1 activity, thereby restoring ferroptosis defense mechanisms through upregulation of GPX4 and SLC7A11 expression, ultimately ...

Plaque‐Hepatic Targeting Nanotherapy Disrupts the PCSK9‐LOX‐1 Axis to Suppress oxLDL in Atherosclerosis

Advanced Science, EarlyView.
Self‑amplifying PCSK9–LOX‑1 feedback axis drives atherosclerotic progression by promoting oxLDL generation and endothelial uptake. A dual‑targeting nanoplatform (siPCSK9@PEAL NPs‑aL) is constructed to simultaneously silence hepatic PCSK9 for lipid lowering and block plaque LOX‑1 for anti‑inflammation.
