Polyphenols, the main antioxidants of diet, have shown anti-inflammatory, antioxidant and anticarcinogenic activities. Here, we compared effects four polyphenolic compounds on ROS production levels matrix metalloproteinase (MMP)-2 -9, which represent important pathogenetic factors breast cancer. THP-1 differentiated macrophages were activated by LPS simultaneously treated with different doses a green tea extract (GTE), resveratrol (RSV), curcumin (CRC) an olive fruit (oliplus). By using 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, found that all tested showed activity in vitro. In addition, GTE, RSV CRC able to counteract induced H

FeSA‐Ir/Metallene Nanozymes Induce Sequential Ferroptosis‐Pyroptosis for Multi‐Immunogenic Responses Against Lung Metastasis

Small, Journal Year: 2024, Volume and Issue: unknown

Published: June 14, 2024

Abstract For cancer metastasis inhibition, the combining of nanozymes with immune checkpoint blockade (ICB) therapy remains major challenge in controllable reactive oxygen species (ROS) generation for creating effective immunogenicity. Herein, new light‐controlled ROS production terms quantity and variety are developed by conjugating supramolecular‐wrapped Fe single atom on iridium metallene lattice‐strained nanoislands (FeSA‐Ir@PF NSs). The Fenton‐like catalysis FeSA‐Ir@PF NSs effectively produced •OH radicals dark, which induced ferroptosis apoptosis cells. While under second near‐infrared (NIR‐II) light irradiation, showed ultrahigh photothermal conversion efficiency (𝜂, 75.29%), cooperative robust generation, photocatalytic O 2 1 caused significant pyroptosis sequential cells pyroptosis, led 99.1% primary tumor inhibition multi‐immunogenic responses vivo. Most importantly, lung is completely achieved inhibitors, as demonstrated different mice models, including circulating (CTCs) model. This work provided inspiration developing treatments inhibition.

Three‐Level Nanoparticle Rocket Strategy for Colorectal Cancer Therapeutics in Photothermal Therapy, Inflammation Modulation, and Cuproptosis Induction

Advanced Healthcare Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 10, 2025

Abstract Disturbances in intracellular copper (Cu) homeostasis can trigger cuproptosis, a new form of cell death, which, when combined with photothermal therapy (PTT), offers promising solution to the persistent challenges colorectal cancer (CRC) treatment. In this study, “three‐level nanoparticle rocket” strategy is developed by engineering Cu 5.4 O, multifunctional Cu‐based nanoenzyme that and has electron transfer properties antioxidant efficiency. O effectively remodels inflammatory environment scavenging reactive oxygen species, thereby overcoming traditional limitations PTT. Concurrently, releases substantial amounts + into malignant cells, disrupting homeostasis, inducing ultimately inhibiting tumor progression. vivo vitro experiments demonstrate operates through multiple successive interlocking stages significantly eradicate tumors, prevent relapse, prolong survival. This study provides profound insights synergistic effects PTT, regulation, cuproptosis within complex microenvironment, presenting innovative approaches for future CRC therapy.

Targeting Nanotherapeutics for Highly Efficient Diagnosis and Treatment of Systemic Lupus Erythematosus through Regulation of Immune Response

Small Science, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 23, 2025

Systemic lupus erythematosus (SLE) is characterized by the production of pathogenic autoantibodies, particularly antidouble‐stranded (ds) DNA antibodies, which contribute to multiorgan damage (lupus nephritis, LN). Hence, there an urgent need recognize and eliminate SLE‐specific anti‐ds antibodies enhance SLE treatment. Herein, mesoporous silica (MSNs) loaded with SeC surface‐modified ctDNA are constructed effectively specific bind anti‐dsDNA for treatment in 125 plasm enabling swift LN diagnosis 36 kidney tissue from patients. As expected, clearance ratio nanotherapeutics significantly greater compared other products commonly used clinical therapies exhibits biocompatibility safety Moreover, MSNs‐DNA can also help visualize distribution lesions kidney. Importantly, combination strategy (MSNs‐DNA@SeC) remove reduce UP regulation B cells T female MRL/lpr model mice alleviate related symptoms. Collectively, resultant data not only presents a straightforward method systematic design nanomedicine targeting effects on treatment, but elucidates potential mechanisms involving pathogenesis progression SLE.

Inflammatory bowel diseases (IBDs) are characterized by dysregulated inflammatory responses, increased reactive oxygen species (ROS), and compromised intestinal barrier function. Current clinical treatments often yield suboptimal responses significant side effects. Given the great potential of Akkermansia muciniphila (AKK) bacterial membrane components in IBD treatment possible pathogenicity live bacteria, to essentially address these challenges, we develop a natural membrane-based single-cell coating, incorporating self-assembled AKK (AKM) astaxanthin (AST), forming protective biological on probiotics. Utilizing Escherichia coli Nissle 1917 (EcN) for oral delivery system, engineer AKM-AST@EcN nanocoated probiotics, demonstrating exceptional gastrointestinal (GI) tract tolerance robust bioactivity. Critically, our findings highlight as promising therapeutic approach while also presenting distinctive strategy probiotic systems.
