Recent comparative studies have shed light on the biochemical implications of mercury ingestion, both in low, persistent concentrations and in elevated acute dosages. Studies have presented models that elucidate how mercury disrupts healthy cells. Mercury’s unique ability to interfere with crucial enzymatic processes at deposition sites is a vital feature of these models. The strong affinity for the sulfhydryl moieties of enzyme catalytic sites leads to enzyme inactivation through permanent covalent modifications. This inactivation can have catastrophic effects on an organism’s metabolic functions. Moreover, it has been found that mercury’s binding to sulfhydryl moieties is highly nonspecific and can occur in various ways. This review aimed to explore the effects of mercury on a broad spectrum of enzymes with a specific focus on how these alterations can detrimentally affect several metabolic pathways.</p></div>","PeriodicalId":491,"journal":{"name":"Biometals","volume":"38 2","pages":"357 - 370"},"PeriodicalIF":4.1,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142998085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 90 CRC patients and 97 controls were involved in the present study. The level of biometals in blood serum and colon tissues (only in CRC cases) was evaluated by inductively-coupled plasma mass-spectrometry. CRC patients are characterized by lower serum Ca, Fe, Se, and Zn, as well as higher serum Co, Cu, Mg, V, and Cu/Zn ratio compared to healthy controls. The lowest serum Zn levels and the highest Cu concentration and Cu/Zn ratio were observed in patients with the largest tumor size. Regression analysis demonstrated that tumor size is a significant negative predictor of serum Se levels, being positively associated with serum Cu/Zn values. The degree of metastasis to regional lymph nodes was inversely associated with circulating Ca, Co, Mg, Zn, and Mn levels. Serum Mg and Mn levels were positively associated with the stage of the disease and tumor location, respectively. Cancerous tissue Ca and Mo levels were lower, while Mg content was higher compared to healthy adjacent tissues. In cancerous tissues a constant but non-significant trend to elevation of tissue Zn content with increasing tumor size was observed. In addition, serum Cu, Zn, and Cu/Zn values positively correlated with the respective tumor values. These findings demonstrate that altered biometal metabolism is associated with CRC, while systemic Cu/Zn ratio may be indicative of Cu and Zn imbalance in cancerous tissue.</p></div>","PeriodicalId":491,"journal":{"name":"Biometals","volume":"38 2","pages":"529 - 544"},"PeriodicalIF":4.1,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142998051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the structural, morphological, and optical properties of pure and biosynthesized ZnSeO₃ catalysts. X-ray diffraction (XRD) analysis confirms the presence of an orthorhombic phase in both catalyst types. Fourier transform infrared spectroscopy (FTIR) reveals the incorporation of secondary metabolites in the biosynthesized ZnSeO₃ catalysts, indicating successful green synthesis. Field-emission scanning electron microscopy (FESEM) demonstrates the formation of needle-shaped nanorod morphology in the prepared catalysts. UV–visible spectroscopy shows a red shift in the optical band gap, with values ranging from 2.40 to 1.60 eV for the biosynthesized ZnSeO₃ catalysts, suggesting enhanced light absorption properties. Barrett–Joyner–Halenda (BJH) analysis highlights the significant influence of plant extract on the surface area of the biosynthesized catalysts. The synthesized ZnSeO₃ catalysts were analyzed for the degradation of Oxytetracycline (OTC) and Rhodamine B (RhB) dyes as well as for their antibacterial activity.

An octahedral environment encircling metal complexes has been demonstrated by the findings of multiple spectroscopic approaches that were employed to demonstrate the structure of the metal complexes. The Coats–Redfern method of thermal analysis was employed to carry out the kinetic and thermodynamic calculations. The crystalline size of ligand was 36.67 nm and for the metal complexes it varies from 22.43 to 49.21 nm. To assess the biological effectiveness of these compounds, molecular docking studies were emanated. The docking binding studies were established through the interaction of metal complexes with human cancer protein, such as 3W2S (ovarian cancer) and 4ZVM (breast cancer). The results exemplified that the complexes are more efficient towards ovarian cancer (3W2S) in contrast to breast cancer (4ZVM) while among complexes, the nickel acetate (− 7.0 kcal/mol) and copper acetate (− 7.9 kcal/mol) complex were more efficient towards 4ZVM and 3W2S receptors respectively. Additionally, DNA binding studies against 1BNA receptor protein was examined from docking evaluations and the finding concludes the highest efficiency of nickel (− 8.1 kcal/mol) complexes. Further, a number of bacterial and fungal strains have been implemented in antimicrobial examinations to assess the compounds effectualness.

The dissemination of antibiotic resistance in this pathogen at an alarming rate could be not only due to the overuse of antibiotics but also due to the stress caused by exposure of bacterium to several environmental contaminants in their niches. In the present study, effect of copper stress on augmentation in the antibiotic resistance of <i>A. baumannii</i> MCC 3114 against three clinically used antibiotics was investigated along with the phenotypic and genotypic alterations in the cell. It induced 8, 44 and 22-fold increase in resistance against colistin, ciprofloxacin and levofloxacin, respectively. Moreover, the biofilm formation of adapted culture was significantly enhanced due to a dense EPS around the cell (as revealed by SEM images). The structural changes in EPS were demonstrated by FTIR spectroscopy. The adequate growth of adapted MCC 3114 despite increased level of ROS indicates its persistence in copper and ROS stress. The physiological alterations in cell viz., increased efflux pump activity and decreased membrane permeability was observed. Molecular analysis revealed increased expression of efflux pump related genes, oxidative stress genes, integron and antibiotic resistance genes. In sum, our study revealed that the exposure of the critical pathogen, <i>A</i>. <i>baunmannii</i> to copper in hospital settings and environmental reservoirs can impose adaptive pressure which may lead to genotypic as well phenotypic changes in cell resulting into the augmentation of antibiotic resistance.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":491,"journal":{"name":"Biometals","volume":"38 2","pages":"485 - 504"},"PeriodicalIF":4.1,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142871022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wild-type <i>D. melanogaster</i> flies were exposed to Cr(hist)₃ at concentrations of 5, 10, 15, and 20 µg/ml, and physiological parameters—including fecundity, fertility, developmental timelines, and antioxidant enzyme activity—were measured.

Specifically, fecundity and fertility increased by 15.6% and 15.5%, respectively, and egg-to-adult viability improved by 15.6% compared to controls. Developmental timelines were shortened, with larval and pupal periods reduced by 7.6% and 7.1%. Additionally, Cr(hist)₃ treatment led to a significant downregulation of lipid peroxidation (MDA) by 17.54% and upregulation in antioxidant enzymes (catalase, glutathione-S-transferase, and superoxide dismutase), indicating improved cellular defence against oxidative damage.
