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.

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 ...

Human iPSCs Derived MSCs‐Secreted Exosomes Modulate Senescent Nucleus Pulposus Cells Induced Macrophage Polarization via Metabolic Reprogramming to Mitigate Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Senescent nucleus pulposus cells drive inflammatory M1 macrophage polarization, exacerbating intervertebral disc degeneration (IDD). Conversely, M1 macrophages accelerate NP cell senescence, creating a vicious cycle. iPSCs‐derived mesenchymal stem cell (iMSCs) exosomes break this loop by delivering miR‐100‐5p to suppress mTORC1/glycolysis in ...

ER‐phagy Activation by AMFR Attenuates Cardiac Fibrosis Post‐Myocardial Infarction via mTORC1 Pathway

Advanced Science, EarlyView.
By catalyzing FAM134B ubiquitination and activating ER‐phagy, AMFR alleviates progressive fibrosis and cardiac dysfunction by inhibiting the mTORC1 pathway. Consequently, these findings underscore the essential role of AMFR‐driven ER‐phagy in mitigating the progression of fibrotic responses, offering a potential therapeutic target for preventing heart ...

Arginine Metabolic Disruption Impairs Hair Regeneration via ROS‐Mediated Inactivation of mTOR Signaling in Androgenetic Alopecia

Advanced Science, EarlyView.
Arginine deficiency accelerates androgenetic alopecia. Serum metabolome shows reduced circulating arginine, while local metabolic disruption depletes follicular reserves, triggering reactive oxygen species (ROS) accumulation and mTOR suppression that induce hair miniaturization.
