Toxicology 2024; 505:153808. [PMID: 38642822 DOI: 10.1016/j.tox.2024.153808] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 04/05/2024] [Accepted: 04/16/2024] [Indexed: 04/22/2024]
Abstract
Nonylphenol (NP) and octylphenol (OP) are environmental contaminants with potential endocrine disrupting effects. However, there is limited research on the mechanisms and intervention of combined NP and OP exposure-induced neurotoxicity. This study aims to explore the cytotoxicity of combined NP and OP exposure and evaluate the potential of Lycium barbarum polysaccharides (LBP) in mitigating the aforementioned toxicity. In present study, LBP (62.5, 125 and 250 µg/mL) were applied to intervene rat adrenal pheochromocytoma (PC-12) cells treated with combined NP and OP (NP: OP = 4:1, w/w; 1, 2, 4 and 8 µg/mL). The results showed that NP and OP induced oxidative stress, disrupted the 5-hydroxytryptamine (5-HT) and cholinergic systems in PC-12 cells. Additionally, they activated the p38 protein kinase (p38) and suppressed the expression of silent information regulation type 1 (SIRT1), monoamine oxidase A (MAOA), phosphorylated cyclic-AMP response binding protein (p-CREB), brain-derived neurotrophic factor (BDNF) and phosphorylated tropomyosin-related kinase receptor type B (p-TrkB). However, N-acetyl-L-cysteine (NAC) treatment counteracted the changes of signalling molecule p38, SIRT1/MAOA and CREB/BDNF/TrkB pathways-related proteins induced by NP and OP. LBP pretreatment ameliorated combined NP and OP exposure-induced oxidative stress and neurotransmitter imbalances. Furthermore, the application of LBP and administration of a p38 inhibitor both reversed the alterations in the signaling molecule p38, as well as the proteins associated to the SIRT1/MAOA and CREB/BDNF/TrkB pathways. These results implied that LBP may have neuroprotective effects via p38-mediated SIRT1/MAOA and CREB/BDNF/TrkB pathways.

Nonylphenol and its derivatives: Environmental distribution, treatment strategy, management and future perspectives. CHEMOSPHERE 2024; 352:141377. [PMID: 38346514 DOI: 10.1016/j.chemosphere.2024.141377] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 01/17/2024] [Accepted: 02/02/2024] [Indexed: 02/20/2024]
Abstract
In recent years, emerging pollutants, including nonylphenol (NP) and nonylphenol ethoxylate (NPE), have become a prominent topic. These substances are also classified as persistent organic pollutants. NP significantly affects the hormone secretion of organisms and exhibits neurotoxicity, which can affect the human hippocampus. Therefore, various countries are paying increased attention to NP regulation. NPEs are precursors of NPs and are widely used in the manufacture of various detergents and lubricants. NPEs can easily decompose into NPs, which possess strong biological and environmental toxicity. This review primarily addresses the distribution, toxicity mechanisms and performance, degradation technologies, management policies, and green alternative reagents of NPs and NPEs. Traditional treatment measures have been unable to completely remove NP from wastewater. With the progressively tightening management and regulatory policies, identifying proficient and convenient treatment methods and a sustainable substitute reagent with comparable product effectiveness is crucial.
