Effects of copper overload on mitochondrial parameters in GBM-1, U-87 MG, and C6 glioma cell linesNARA Subscribed
Over the years, there has been growing interest in developing new therapies for glioblastoma, and copper compounds have emerged as promising therapeutic targets due to their antitumoral properties. In this context, this study aimed to investigate the effects of high copper levels on cell viability, mitochondrial physiology, PINK1 content, and the expression of PGC-1α and TFAM in distinct glioma cell lines, mainly considering t...
Ferric carboxymaltose (FCM) and ferric derisomaltose (FDI) are key for treating iron deficiency anemia. However, FCM has been shown to raise serum fibroblast growth factor (FGF)-23 levels, causing hypophosphatemia and alterations in bone turnover in some patients. To date, it is unknown if FCM and FDI also affect bone mineralization. This study examined FDI and FCM effects on bone mineralization and FGF-23 in healthy mice, avo...
Bacterial pathogens must rapidly adapt to fluctuating metal availability within the host, where essential micronutrients are actively sequestered as part of nutritional immunity. Among these, zinc is a critical cofactor for a wide array of enzymes and regulatory proteins, and its availability is tightly linked to the expression of key virulence traits in Pseudomonas aeruginosa . This opportunistic pathogen employs different zi...
Chagas disease remains a major public health challenge, and there is a need for new therapeutic agents. N-heterocyclic carbene (NHC) complexes, particularly those linked to silver or gold, have shown significant anticancer, antimicrobial, and antiparasitic activities. This study aimed to evaluate the efficacy of four NHC compounds (QMT3, QMT4, QMT7, and QMT8) against Trypanosoma cruzi , the causative agent of Chagas disease. I...
The different affinity of the two metal-binding sites of human ferroportin drives outward directionality of transportNARA Subscribed
Ferroportin, the only known cellular iron exporter, belongs to the major facilitator superfamily of transporters, which cycle between inward-open, occluded and outward-open conformations to translocate substrates across membranes. Recently reported cryoEM structures of ferroportin identified two metal-binding sites in the central cavity of the protein, with site S1 that includes residues D39 and H43, while site S2 is formed by...
Antidiabetic potential of vanadium complexes combined with olive leaf extracts: a viable approach to reduce metal toxicityNARA Subscribed
Vanadium compounds are known for their antidiabetic properties due to their ability to interfere with numerous mechanisms that lead to the decrease of blood glucose levels. Although some of these compounds have reached clinical trials and have the advantage of being orally administrable, no vanadium-containing drugs are currently available on the market, primarily due to the high doses required, which can lead intestinal and r...
Heavy metals in biological samples of cancer patients: a systematic literature reviewNARA Subscribed
The majority of the so-called heavy metals are suspected to be involved in a number of pathologies and play a role in human carcinogenesis. Some of them (i.e. arsenic (As), cadmium (Cd), chromium (Cr), lead (Pb), mercury (Hg) and nickel (Ni)) have been defined as carcinogens, increasing the susceptibility of tumor development and progression in humans. Moreover, Ni, Cr, Cd, Hg, and Pb together with zinc (Zn) and iron (Fe), may...
Revealing the nuclearity of iron citrate complexes at biologically relevant conditionsNARA Subscribed
Citric acid plays an ubiquitous role in the complexation of essential metals like iron and thus it has a key function making them biologically available. For this, iron(III) citrate complexes are considered among the most significant coordinated forms of ferric iron that take place in biochemical processes of all living organisms. Although these systems hold great biological relevance, their coordination chemistry has not been...
Tobacco as an efficient metal accumulatorNARA Subscribed
Tobacco ( Nicotiana tabacum L.) is an important industrial crop plant. However, it efficiently accumulates metals, primarily cadmium (Cd) and also zinc (Zn), in its leaves. Therefore, it could be a source of cadmium intake by smokers. On the other hand, as a high leaf metal accumulator, it is widely used for phytoremediation of metal-contaminated soil. Both issues provide an important rationale for investigating the processes...
