Metals to combat antimicrobial resistance

Nature Reviews Chemistry, Journal Year: 2023, Volume and Issue: 7(3), P. 202 - 224

Published: Feb. 8, 2023

Bacteria, similar to most organisms, have a love–hate relationship with metals: specific metal may be essential for survival yet toxic in certain forms and concentrations. Metal ions long history of antimicrobial activity received increasing attention recent years owing the rise resistance. The search antibacterial agents now encompasses ions, nanoparticles complexes (‘metalloantibiotics’). Although advanced clinic, metalloantibiotics are vast underexplored group compounds that could lead much-needed new class antibiotics. This Review summarizes developments this growing field, focusing on advances development metalloantibiotics, particular, those which mechanism action has been investigated. We also provide an overview alternative uses combat bacterial infections, including photodynamic therapy radionuclide diagnosis infections. Metals their promising source Their 3D geometry potential multiple mechanisms important assets; however, substantial investment research is needed advance them clinic.

Altered Iron Metabolism and Impact in Cancer Biology, Metastasis, and Immunology

Frontiers in Oncology, Journal Year: 2020, Volume and Issue: 10

Published: April 9, 2020

Iron is an essential nutrient that plays a complex role in cancer biology. metabolism must be tightly controlled within cells. Whilst fundamental to many cellular processes and required for cell survival, excess labile iron toxic Increased associated with malignant transformation, progression, drug resistance immune evasion. Depleting intracellular stores, either the use of chelating agents or mimicking endogenous regulation mechanisms such as microRNAs, present attractive therapeutic opportunities, some which are currently under clinical investigation. Alternatively, overload can result form regulated death, ferroptosis, activated cells presenting alternative anti-cancer strategy. This review focuses on alterations enable meet metabolic demands during different stages tumorigenesis relation metastasis response. The strength current evidence considered, gaps knowledge highlighted controversies relating targeting potential discussed. key question we address this whether modulation represents useful approach treating metastatic disease it could employed combination existing targeted drugs immune-based therapies enhance their efficacy.

Impaired lysosomal acidification triggers iron deficiency and inflammation in vivo

eLife, Journal Year: 2019, Volume and Issue: 8

Published: Dec. 3, 2019

Lysosomal acidification is a key feature of healthy cells. Inability to maintain lysosomal acidic pH associated with aging and neurodegenerative diseases. However, the mechanisms elicited by impaired remain poorly understood. We show here that inhibition triggers cellular iron deficiency, which results in mitochondrial function non-apoptotic cell death. These effects are recovered supplying via lysosome-independent pathway. Notably, deficiency sufficient trigger inflammatory signaling cultured primary neurons. Using mouse model acidification, we observed robust response brain, verified vivo magnetic resonance imaging. Furthermore, brains these mice present pervasive signature instability DNA (mtDNA), both corrected supplementation diet iron. Our highlight novel mechanism linking malfunction inflammation vivo.

Inorganic Biomaterials for Regenerative Medicine

ACS Applied Materials & Interfaces, Journal Year: 2020, Volume and Issue: 12(5), P. 5319 - 5344

Published: Jan. 28, 2020

Regenerative medicine leverages the innate potential of human body to efficiently repair and regenerate damaged tissues using engineered biomaterials. By designing responsive biomaterials with appropriate biophysical biochemical characteristics, cellular response can be modulated direct tissue healing. Recently, inorganic have been shown regulate responses including cell–cell cell–matrix interactions. Moreover, ions released from these mineral-based play a vital role in defining cell identity, as well driving tissue-specific functions. The intrinsic properties biomaterials, such release bioactive (e.g., Ca, Mg, Sr, Si, B, Fe, Cu, Zn, Cr, Co, Mo, Mn, Au, Ag, V, Eu, La), leveraged induce phenotypic changes cells or modulate immune microenvironment healing regeneration. Biophysical characteristics topography, charge, size, electrostatic interactions, stiffness by addition micro- nanoparticles polymeric networks also an important their biological response. In this Review, we discuss recent emergence harness regenerative body. Specifically, will various effects inorganic-based materials directing for applications.

Identification of Frataxin as a regulator of ferroptosis

Redox Biology, Journal Year: 2020, Volume and Issue: 32, P. 101483 - 101483

Published: March 2, 2020

Ferroptosis is a newly discovered form of non-apoptotic regulated cell death and characterized by iron-dependent lipid peroxidation. Due to the enhanced dependence on iron in cancer cells, induction ferroptosis becoming promising therapeutic strategy. However, precise underlying molecular mechanism regulation process remains largely unknown. In present study, we demonstrate that protein Frataxin (FXN) key regulator modulating homeostasis mitochondrial function. Suppression FXN expression specifically repressed proliferation, destroyed morphology, impeded Fe-S cluster assembly activated starvation stress. Moreover, suppression significantly erastin-induced through accelerating free accumulation, peroxidation resulted dramatic mitochondria morphological damage including fragmentation vanished cristae. addition, this type was confirmed be ferroptosis, since it could pharmacologically restored ferroptotic inhibitor Fer-1 or GSH, but not inhibitors apoptosis, necrosis. Vice versa, enforced blocked response ferroptosis. More importantly, pharmacological genetic blocking signal completely restore resistance knockdown cells xenograft graft vivo. This paper suggests novel modulator, as well potential provided target improve antitumor activity based
