SIRT7‐Mediated H2BK120 Succinylation Drives Aberrant Mitophagy in Sepsis‐Associated Cognitive Dysfunction

open access: yesAdvanced Science, EarlyView.
Sepsis triggers hippocampal SIRT7 loss, promoting histone H2B succinylation and activation of the PD‐1/PD‐L1–PINK1 axis. This metabolic‐epigenetic cascade drives aberrant mitophagy and neuronal injury, ultimately causing cognitive deficits. Targeting SIRT7‐dependent succinylation offers a potential strategy to protect brain function during sepsis ...

FTSJ3‐Mediated 2′‐O‐Methylation of HSPA5 mRNA Stabilizes BOP1 via SUMOylation to Drive DRP1‐Dependent Mitochondrial Fission and Fatty Acid Oxidation in Lung Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
The RNA methyltransferase FTSJ3 drives lung squamous cell carcinoma progression by catalyzing 2′‐O‐methylation of HSPA5 mRNA, which stabilizes BOP1 through SUMOylation and activates DRP1/SREBP1‐mediated mitochondrial fission and fatty acid oxidation. Targeting this axis with liposomal siRNA potently suppresses tumor growth and metastasis ABSTRACT Lung ...

An Injectable, Self‐Expanding Hemostatic Foam for Field‐Compatible Postpartum Hemorrhage Management

open access: yesAdvanced Science, EarlyView.
Postpartum hemorrhage is the leading cause of maternal death worldwide, yet many treatments are hard to use outside well‐equipped hospitals. This work introduces an easy‐to‐use device that rapidly delivers a degradable foam into the uterus. The foam stops bleeding through pressure and clotting support, offering a practical option for low‐resource ...

Fumarate Hydratase Lactylation Exacerbates Traumatic Brain Injury Pathology via Mitochondrial Dysfunction and Neuroinflammation

open access: yesAdvanced Science, EarlyView.
Tian et al. reveal that FH K112 lactylation is elevated after TBI, leading to fumarate accumulation, mitochondrial damage, mtDNA release and amplified neuroinflammation. AARS2 and SIRT3 act as the “writer” and “eraser” for FH K112 lactylation. The peptide Pep‐K112 targeting this site alleviates brain injury, highlighting a potential therapeutic target.

ROS‐Responsive Nanoparticle Delivery of Dexmedetomidine Protects the Gut Vascular Barrier After Intestinal Ischemia/Reperfusion via the HDAC‐H3K27ac‐TCF4 Axis

open access: yesAdvanced Science, EarlyView.
A low dose of dexmedetomidine, delivered by ROS‐responsive nanoparticles, preferentially accumulates in the ischemic intestine and restores gut vascular barrier integrity after ischemia/reperfusion injury. This nanoparticle‐based strategy prevents bacterial translocation and liver damage without cardiorespiratory side effects, working through HDAC ...
