Antimicrobial textile products are developing rapidly as an important part of functional textiles. Silver nanoparticles (AgNPs) are nanotechnology products with antimicrobial properties. However, exposure to nanoparticles in daily life is an important issue for public health, still being updated. Aim was to evaluate the effects of AgNPs on the development of zebrafish embryos focusing on Wnt pathway, proliferation, oxidant-antioxidant status, and apoptosis. The expressions of ccnd1 and gsk3β were determined by RT-PCR, whereas β-catenin and proliferative cell antigen (PCNA) expressions were determined immunohistochemically. Lipid peroxidation, superoxide dismutase, and glutathione-S-transferase activities were determined spectrophotometrically. Apoptosis was determined using acridine orange staining. Oxidant status, apoptosis, immunohistochemical PCNA, and β catenin staining increased, whereas ccnd1 and antioxidant enzyme activities decreased in AgNPs-exposed embryos in a dose-dependent manner. Our results indicate the interaction of possible mechanisms that may be responsible for the toxic effects of AgNPs in zebrafish embryos.
抗菌纺织品是功能纺织品的重要组成部分,发展迅速。纳米银颗粒(AgNPs)是具有抗菌性能的纳米技术产品。然而,日常生活中纳米颗粒的暴露是一个重要的公共健康问题,仍在不断更新。本研究旨在评估 AgNPs 对斑马鱼胚胎发育的影响,重点关注 Wnt 通路、增殖、氧化应激状态和细胞凋亡。通过 RT-PCR 测定 ccnd1 和 gsk3β 的表达,通过免疫组织化学法测定 β-catenin 和增殖细胞核抗原(PCNA)的表达。通过分光光度法测定脂质过氧化、超氧化物歧化酶和谷胱甘肽-S-转移酶的活性。使用吖啶橙染色法测定细胞凋亡。结果表明,AgNPs 暴露组胚胎的氧化应激状态、细胞凋亡、免疫组织化学 PCNA 和 β-catenin 染色增加,而 ccnd1 和抗氧化酶活性则呈剂量依赖性降低。这些结果表明,AgNPs 可能通过多种机制与斑马鱼胚胎的毒性作用相互作用。
