Loss of STARD7 Triggers Metabolic Reprogramming and Cell Cycle Arrest in Breast Cancer

Advanced Science, EarlyView.
Breast cancer cells undergo metabolic and transcriptomic reprogramming to support aberrant cell proliferation. Their mitochondria rely on the transfer of phosphatidylcholine from the endoplasmic reticulum to their membranes by STARD7, a candidate upregulated in breast cancer, to be functional.

Mitochondrial Regulation of CD8⁺ T Cells: Mechanisms and Therapeutic Modulation

Advanced Science, EarlyView.
This article comprehensively explores the pivotal role of mitochondrial function in CD8⁺ T cell immunotherapy. It highlights how mitochondrial dynamics regulate T cell activation, differentiation, and persistence, and how mitochondrial dysfunction leads to immune exhaustion and impaired antitumor/antiviral responses.

A Human Engineered Heart Tissue‐Derived Lipotoxic Diabetic Cardiomyopathy Model Revealed Early Benefits of Empagliflozin

Advanced Science, EarlyView.
This study develops a human engineered heart tissue‐derived model of diabetic cardiomyopathy that accurately replicates the dynamic changes in the structural, contractile, and electrophysiological properties of the myocardium. Furthermore, this model is used to confirm the direct protective effects of empagliflozin on the heart through an SGLT2 off ...

Cellular Adaptation to Mechanical Stress Emerges via Cell Shrinkage Triggered by Nonlinear Calcium Elevation

Advanced Science, EarlyView.
Here, a decision‐making mechanism underlying mechanical adaptation is demonstrated. This study demonstrates that cellular adaptation to mechanical stress can be induced by applying low‐amplitude stretch to cells. When the stretch reaches a critical amplitude threshold, it triggers Ca2⁺‐dependent positive feedback, which induces cholesterol efflux and ...

STING COPII ER Export Trafficking and Signaling Primed by Phosphorylation Switches

Advanced Science, EarlyView.
This schematic outlines STING trafficking and signaling via coat protein II (COPII)‐mediated endoplasmic reticulum (ER) export. Following cyclic GMP‐AMP (cGAMP) stimulation, TANK‐binding kinase 1 (TBK1) activates on COPII vesicles, partially dissociating into the cytosol to phosphorylate ER‐localized STING, creating pSGME/pFS COPII‐sorting motifs ...

STK25 Loss Augments Anti‐PD‐1 Therapy Efficacy by Regulating PD‐L1 Stability in Colorectal Cancer

Advanced Science, EarlyView.
This study demonstrates that STK25 depletion facilitates CRC immune escape through the inhibition of PD‐L1 Ser283 phosphorylation‐mediated ubiquitination, and promotes tumor growth. Furthermore, these findings identify STK25 as a potential therapeutic target to trigger antitumor immunity and promote immunotherapy efficacy. Abstract Tumor immune evasion

Antagonistic Ghd7‐OsNAC42 Complexes Modulate Carbon and Nitrogen Metabolism to Achieves Superior Quality and High Yield in Rice

Advanced Science, EarlyView.
The complex centered on Ghd7 binds to numerous carbon and nitrogen metabolism genes on the genome through the corresponding motifs and transactivates the transcriptional expression of these carbon and nitrogen metabolism genes. With the assistance of OsNAC42 and other unknown Ghd7‐interacting proteins, this complex can regulate different metabolic ...

Autophagy‐Mediated Suppression of Tumor Growth by Food‐Grade Lipid Nanoparticles in Mice

Advanced Science, EarlyView.
This work reveals a novel extracellular nanoparticle transport and metabolic pathway. Following cellular uptake, Food‐grade lipid nanoparticles (FLNs) selectively fuse with lipid droplets (LDs) rather than lysosomes, driving LDs accumulation. This process activates autophagy through the AMPK‐mTOR‐ULK1 signaling axis, facilitating tumor progression ...
