Mixed heavy metals exposure affects the renal function mediated by 8-OHG: A cross-sectional study in rural residents of China. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2023; 317:120727. [PMID: 36427825 DOI: 10.1016/j.envpol.2022.120727] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Revised: 11/07/2022] [Accepted: 11/21/2022] [Indexed: 06/16/2023]
Abstract
Heavy metals are important risk factors for kidney, but their co-exposure effect on kidney and related mechanism remain unclear. This study evaluated the relationship between heavy metals and renal function, and the feasible mediation effect of oxidative stress. Based on the Dongdagou-Xinglong cohort, participants were recruited and their information were collected through questionnaires and physical examinations. The urine concentration of heavy metals like Cobalt, Nickel, Molybdenum, Cadmium, Antimony, Copper, Zinc, Mercury, Lead, Manganese, and renal injury biomarkers like β2-microglobulin, β-N-Acetylglucosaminidase, retinol-binding protein, 8-hydroxyguanine (8-OHG) were measured and corrected by creatinine. Linear regression was conducted to analyze the relationship between metals and renal biomarkers. Bayesian kernel machine regression, weighted quantile sum and quantile-based g-computation were applied to analyze the association between metal mixtures and renal biomarkers. Finally, the mediating effect of 8-OHG was analyzed through the mediation model. We found that these metals were positively related with renal biomarkers, where copper showed the strongest relationship. The co-exposure models showed that renal biomarkers increased with the concentration of mixtures, particularly for cadmium, copper, mercury, manganese. In addition, the proportion of 8-OHG in mediating effect of metals on renal function ranged from 2.6% to 86.9%. Accordingly, the renal function damage is positively associated with metals, and 8-OHG may play an important mediating role.

Oyeleye SI, Ogunsuyi OB, Adedeji V, Olatunde D, Oboh G. Citrus spp. essential oils improve behavioral pattern, repressed cholinesterases and monoamine oxidase activities, and production of reactive species in fruit fly (Drosophila melanogaster) model of Alzheimer's Disease. J Food Biochem 2020; 45:e13558. [PMID: 33179303 DOI: 10.1111/jfbc.13558] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 10/14/2020] [Accepted: 10/15/2020] [Indexed: 11/26/2022]
Abstract
Much emphasis has been placed on the biological activities of citrus peel's essential oils (CPEOs) against human ailments. This study investigated the effect of Citrus limon and Citrus reticulata peel's essential oils (EOs) on behavioral and neurochemical imbalance in transgenic and Harwish (Wild) fruit flies. Flies were divided into seven groups comprising of the control and those that were fed with 0.1, 0.5, and 1.0 µg/ml of the dietary inclusions of study CPEOs for 7 days. Thereafter, behavioral profile was examined using lethality response and negative geotaxis assays. Effect of the EOs on cholinesterase and monoamine oxidase (MAO) activities, and antioxidative parameters were determined. The result showed a significant improvement of behavioral pattern and biochemical parameters of the flies fed with studied CPEOs inclusive diets. Conclusively, both EOs exert neuroprotective capability by reducing cholinesterases and monoamine activities, and also prevent oxidative stress, which are implicated in neuronal dysfunction in humans. PRACTICAL APPLICATIONS: With the growing increase in the search for safer alternatives, having no side effects, for the management of neurodegenerative diseases, a large proportion of the populace is beginning to find solace in the use of natural products. Also, the wide array of similarities between the humans and the dipteran insects, fruit flies is a perfect organism for the study of neurodegenerative diseases. Therefore, this study presents the neuroprotective potentials of lemon and tangerine peels-derived EOs, and the possibility of their exploration as neuroactive agents and alternative in the management of Alzheimer's disease (AD).
