Membrane Fusion‐Mediated Cytosolic Delivery of Threose Nucleic Acids via Homotypic Nanoparticles Overcomes Drug Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study introduces a biomimetic “nanofusion” platform that integrates the biostability of threose nucleic acids (TNA) with homotypic cell‐membrane cloaking to combat drug‐resistant TNBC. By leveraging a non‐canonical membrane‐fusion pathway for direct cytosolic delivery, the platform bypasses endosomal sequestration. To achieve potent AKT2 silencing

Gallic Acid Reduces Experimental Colitis in Rats by Downregulation of Cathepsin and Oxidative Stress

Erciyes Medical Journal, 2020
Objective: Ulcerative colitis (UC) is an idiopathic inflammatory bowel disease (IBD) with common, repetitive inflammation of the colon and rectum, which is highly defined by loss of blood on colon mucosa, ulceration and acute inflammation.

Targeting the HSPA8‐CMA‐ATP6V1A Axis Triggers Lysosomal Hyperacidification and Catastrophic Vacuolation in Prostate Cancer

Advanced Science, EarlyView.
Our experimental evidence supports a model in which ALO targets the HSPA8‐CMA‐ATP6V1A axis to induce lysosomal hyperacidification and initiate osmotic and lipidomic stress. These changes are associated with LMP and loss of lysosomal integrity in prostate cancer cells.

Caspase-Mediated Cleavage of Human Cortactin during Influenza A Virus Infection Occurs in Its Actin-Binding Domains and Is Associated with Released Virus Titres

Viruses, 2020
Influenza A virus (IAV) exploits host factors to multiply and cause disease. An in-depth knowledge of this interaction of IAV with the host will aid the development of anti-IAV intervention strategies.

Stromal Regulation of Tumor Perineural Invasion: A Multicellular and Neuro‐Ecological Perspective

Advanced Science, EarlyView.
This review reframes perineural invasion (PNI) as a dynamic, multicellular process within the tumor–nerve–stromal ecosystem. The authors delineate how cancer‐associated fibroblasts, Schwann cells, and immune cells remodel the neural niche to facilitate tumor spread.

Analysis of Resistance of Ebola Virus Glycoprotein-Driven Entry Against MDL28170, An Inhibitor of Cysteine Cathepsins

Pathogens, 2019
Ebola virus (EBOV) infection can cause severe and frequently fatal disease in human patients. The EBOV glycoprotein (GP) mediates viral entry into host cells.

A Pancreatitis‐Inspired Trypsinogen Nanoplatform Reprograms Tumor‐Associated Macrophages via NF‐κB for Pancreatic Cancer Immunotherapy

Advanced Science, EarlyView.
Trypsinogen‐loaded nanoparticles reprogram TAMs via NF‐κB/NLRP3, driving M2→M1 conversion and potent phagocytosis to unleash antitumor immunity. ABSTRACT Although reprogramming tumor‐associated macrophages (TAMs) represents a promising therapeutic strategy, approaches that are both precise and safe remain scarce.

Heparin modulates the endopeptidase activity of Leishmania mexicana cysteine protease cathepsin L-Like rCPB2.8

, 2013
Cysteine protease B is considered crucial for the survival and infectivity of the Leishmania in its human host. Several microorganism pathogens bind to the heparin-like glycosaminoglycans chains of proteoglycans at host-cell surface to promote their ...

Exploring Extracellular Vesicles Biogenesis in Hypothalamic Cells through a Heavy Isotope Pulse/Trace Proteomic Approach

Cells, 2020
Studies have shown that the process of extracellular vesicles (EVs) secretion and lysosome status are linked. When the lysosome is under stress, the cells would secrete more EVs to maintain cellular homeostasis.
