Membrane Transporters as Mediators of Cisplatin Effects and Side Effects

Scientifica, 2012
Transporters are important mediators of specific cellular uptake and thus, not only for effects, but also for side effects, metabolism, and excretion of many drugs such as cisplatin.

The role of the host—Neutrophil biology

Periodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Essential Cys-Pro-Cys Motif ofCaenorhabditis elegansCopper Transport ATPase [PDF]

Bioscience, Biotechnology, and Biochemistry, 1998
Caenorhabditis elegans putative copper ATPase (CUA-1) had been functionally expressed in a yeast delta ccc2 mutant (copper ATPase gene disruptant). We found that CUA-1 with Cys-Pro-Cys to Cys-Pro-Ala mutation could not rescue the yeast delta ccc2 mutant, suggesting that the carboxyl terminal cysteine residue in the conserved Cys-Pro-Cys motif is ...

Host and Pathogen Copper-Transporting P-Type ATPases Function Antagonistically during Salmonella Infection [PDF]

Infection and Immunity, 2017
ABSTRACT Copper is an essential yet potentially toxic trace element that is required by all aerobic organisms. A key regulator of copper homeostasis in mammalian cells is the copper-transporting P-type ATPase ATP7A, which mediates copper transport from the cytoplasm into the secretory pathway, as well as copper export across the ...

Light Activated Induction of Cuproptosis in Resistant Cancer Cells Using Polymeric BODIPY Nanoparticles for Photoactivated Chemotherapy

Advanced Functional Materials, EarlyView.
This article presents a photo‐responsive nanoparticle platform that precisely triggers copper‐dependent cuproptotic cell death in (drug‐resistant) cancer cells. The system remains stable and inactive in the dark but releases cytotoxic species upon red‐light irradiation, achieving potent activity in drug‐resistant breast cancer cells.

Lysosome‐Acidifying Nanoparticles Rescue A30P α‐Synuclein Induced Neuronal Death in Cellular and Drosophila Models of Parkinson's Disease

Advanced Healthcare Materials, EarlyView.
Lysosome‐targeted acidic nanoparticles based on a biodegradable poly(ethylene tetrafluorosuccinate‐co‐succinate) copolymer are engineered to restore impaired lysosomal acidification through pH‐responsive intracellular degradation. Localized acid release enhances autophagic proteolysis, reduces α‐synuclein accumulation, and preserves dopaminergic neuron

Biomimetic Copper‐Doped Nano‐Aluminum Adjuvant Potentiates Therapy in Chemoresistant Acute Myeloid Leukemia

Advanced Healthcare Materials, EarlyView.
We developed a novel copper‐doped aluminum nano‐adjuvant (CuNA) to overcome cytarabine resistance in acute myeloid leukemia (AML). CuNA effectively sensitizes drug‐resistant AML cells to cytarabine by inducing mitochondrial dysfunction and inhibiting HMGCR/GPX4 to amplify ferroptosis.

CORE: Cholesterol Altered Lipid Nanoparticles for Splenic Expression of mRNA Payloads

Advanced Healthcare Materials, EarlyView.
In this paper researchers introduce CORE LNPs, a new class of lipid nanoparticles engineered to redirect mRNA expression away from the liver and into the spleen, a key immune organ. By combining chemical design with computational tools, they created cholesterol analogs that enable precise spleen‐targeted expression, providing greater applications for ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

A Dual‐Responsive Versatile Nanohybrid Orchestrating Tumor Elimination and Tumor‐Associated Osteolysis Restoration via Sequential Release

Advanced Science, EarlyView.
The versatile CaO2@CuMOF@HAP nanohybrid demonstrates an outstanding MMP9/pH‐triggered release performance for sequential release of osteogenic growth peptide into deep‐seated tumor‐infiltrated bone destruction areas and dual ions into tumor cells, enabling efficient tumor‐associated osteolysis restoration and tumor elimination for more comprehensive ...
