Regulating Tumor Metabolic Reprogramming with Biomimetic Co‐Delivery of Simvastatin and Kynureninase for Immunotherapy

open access: yesAdvanced Science, EarlyView.
After the intravenous injection of biomimetic and pH/ROS‐responsive PTSK@CRM, the nanoparticles can be accumulated in tumors and release Sim and KYNase to inhibit the tumor growth, regulate the metabolism of cholesterol and Kyn, and reverse the immunosuppressive tumor microenvironment.

Ribosome Homeostasis Regulated by SETD2 Preserves Intestinal Epithelial Barrier

open access: yesAdvanced Science, EarlyView.
SETD2 ablation causes dysregulation and recruitment defects of ribosome biogenesis factors, resulting in translational disorders of barrier maintenance genes, thereby compromising the intestinal barrier. These findings unveil a previously unappreciated role of ribosome biogenesis and translational regulation in preserving the intestinal epithelial ...

Expandable Nanocomposite Shape‐Memory Hemostat for the Treatment of Noncompressible Hemorrhage

open access: yesAdvanced Science, EarlyView.
A nanocomposite‐coated shape memory foam rapidly expands, accelerates clotting, and reduces blood loss in vivo. Its fast volumetric expansion and strong procoagulant activity make it a promising hemostat for treating deep, noncompressible hemorrhage.

Dysfunctional TRIM31 of POMC Neurons Provokes Hypothalamic Injury and Peripheral Metabolic Disorder under Long‐Term Fine Particulate Matter Exposure

open access: yesAdvanced Science, EarlyView.
Particulate matter ≤2.5 µm (PM2.5) elevates risks of neurological and chronic metabolic diseases, but the underlying mechanisms linking PM2.5‐induced central nervous system (CNS) injury to metabolic dysfunction remain unclear. Hypothalamic pro‐opiomelanocortin‐expressing (POMC+) neurons regulate systemic metabolic homeostasis, and tripartite motif ...

HPD is an m6A Methyltransferase that Protects Colorectal Cancer Cells from Ferroptotic Cell Death by m6A Methylating SLC7A11/GPX4

open access: yesAdvanced Science, EarlyView.
This study reveals that the tyrosine metabolic enzyme HPD functions as a previously uncharacterized, METTL3‐independent m6A methyltransferase. It promotes colorectal tumor progression by coordinately regulating the SLC7A11/GPX4 axis to suppress ferroptosis.

Cancer Cell‐Intrinsic Cholesterol Induces Lipid‐Associated Macrophage Differentiation via SP1 Palmitoylation to Promote Prostate Cancer Progression

open access: yesAdvanced Science, EarlyView.
Cancer cell‐intrinsic cholesterol promotes the S‐palmitoylation of SP1, increasing its nuclear translocation and driving the transcription and secretion of MDK, which in turn facilitates the differentiation of macrophages into a lipid‐associated phenotype.

Twin-Arginine Protein Translocation.

Current Topics in Microbiology and Immunology, 2016
Twin-arginine protein translocation systems (Tat) translocate fully folded and co-factor-containing proteins across biological membranes. In this review, we focus on the Tat pathway of Gram-positive bacteria. The minimal Tat pathway is composed of two components, namely a TatA and TatC pair, which are often complemented with additional TatA-like ...

Mitochondrial protein translocation-associated degradation

Nature, 2019
Mitochondrial biogenesis and functions depend on the import of precursor proteins via the 'translocase of the outer membrane' (TOM complex). Defects in protein import lead to an accumulation of mitochondrial precursor proteins that induces a range of cellular stress responses.

Protein Translocation Across Membranes

Science, 1988
Many newly synthesized proteins must be translocated across a membrane to reach their final destinations. Translocation requires a signal on the protein itself, a loose conformation of the protein, energy, and receptor-like components in the cytosol and on the target membrane.
