Nanoplastic Exposure at Environmental Concentrations Disrupts Hepatic Lipid Metabolism through Oxidative Stress Induction and Endoplasmic Reticulum Homeostasis Perturbation

Environmental Science & Technology, Год журнала: 2023, Номер 57(38), С. 14127 - 14137

Опубликована: Сен. 8, 2023

In this study, we investigated the mechanism underlying perturbation of hepatic lipid metabolism in response to micro/nanoplastic (MP/NP) exposure at environmentally relevant concentrations. Polystyrene (PS) MPs/NPs with different sizes (0.1, 0.5, and 5.0 μm) were studied for their effects on homeostasis function Nile tilapia (Oreochromis niloticus) liver. Results showed that PS readily internalized accumulated various internal organs/tissues, especially fish liver muscle. Smaller-sized NPs caused more severe toxicity than larger MPs, including steatosis, inflammatory response, disturbed function. Mechanistically, a particle size 100 nm perturbed protein endoplasmic reticulum (ER) by inhibiting expression chaperone proteins genes involved ER-associated degradation. This led activation PERK-eIF2α pathway, which dysfunction metabolism. Induction oxidative stress Nrf2/Keap1 pathway also NP-induced accumulation. These findings highlight potential adverse environmental aquatic organisms, raising concerns about ecotoxicity food safety.

Metal-organic framework membrane for waterborne micro/nanoplastics treatment

Chemical Engineering Journal, Год журнала: 2023, Номер 474, С. 145715 - 145715

Опубликована: Авг. 29, 2023

Micro/nanoplastics (MPs/NPs) are widespread and pose a significant threat to the environment. Conventional polymeric membrane filtration struggles completely remove MPs/NPs from water wastewater. However, metal–organic frameworks (MOFs)-based membranes have gained attention due their potential in tunable hydrophilicity, pore structure, low surface roughness, dual charge, compatibility with matrix materials, resistance biofouling. This article critically analyzes factors affecting performance of MOF removing MPs/NPs, interaction mechanism, limitations conventional systems, advantages membranes. Despite promising potential, MOF-based also face challenges such as re-aggregation nanoparticles, cross-contamination during poor structural stability. paper discusses how mitigate these problems by incorporating different materials MOFs. Overall, high

Fate and behaviour of Microplastics (> 25µm) within the water distribution network, from water treatment works to service reservoirs and customer taps

Water Research, Год журнала: 2024, Номер 255, С. 121508 - 121508

Water treatment works have previously shown high efficiency in removing microplastics > 25 µm from raw source water. However, what is less well known the extent to which of this size class are generated or lost within water distribution network, particularly whether there a greater presence customer tap than outlet. This study focused on 21 different types synthetic polymer particles with sizes larger examined through multiple rounds sampling at outlets (WTW), service reservoirs (SR), and taps (CT) managed by seven companies Britain. Nineteen polymers were detected; their signature concentration varied based round sampling, location supply company responsible for managing supply. Among examined, polyamide (PA), polyethene terephthalate (PET), polypropylene (PP), polystyrene (PS) most commonly found. Apart PET having its highest 0.0189 microplastic per litre (MP/L) SR, concentrations other three frequent (PS = 0.017 MP/L, PA 0.0752 PP= 0.1513 MP/L) CT. The overall prevalence network low, but was variability occurrences. These spatial temporal variations suggested that MP may exist as series pulses. Given types, potential some originate materials used domestic plumbing systems cannot be ruled out. As found before, absolute number remained extremely low.

The impact of nanomaterials on autophagy across health and disease conditions

Cellular and Molecular Life Sciences, Год журнала: 2024, Номер 81(1)

Опубликована: Апрель 17, 2024

Abstract Autophagy, a catabolic process integral to cellular homeostasis, is constitutively active under physiological and stress conditions. The role of autophagy as defense response becomes particularly evident upon exposure nanomaterials (NMs), especially environmental nanoparticles (NPs) nanoplastics (nPs). This has positioned modulation at the forefront nanotechnology-based therapeutic interventions. While NMs can exploit enhance outcomes, they also trigger it pro-survival against NP-induced toxicity. Conversely, heightened may lead regulated cell death (RCD), in particular autophagic death, NP exposure. Thus, relationship between exhibits dual nature with Recognizing decoding these intricate patterns are essential for pioneering next-generation autophagy-regulating NMs. review delves into present-day potential autophagy-modulating NMs, shedding light on their status clinical trials, intervention applications discusses potency application early indicator NM Graphical

Bovine Serum Albumin Bends Over Backward to Interact with Aged Plastics: A Model for Understanding Protein Attachment to Plastic Debris

Environmental Science & Technology, Год журнала: 2024, Номер 58(23), С. 10207 - 10215

Опубликована: Май 29, 2024

Plastic pollution, a major environmental crisis, has variety of consequences for various organisms within aquatic systems. Beyond the direct toxicity, plastic pollution potential to absorb biological toxins and invasive microbial species. To better understand capability debris adsorb these species, we investigated binding model protein bovine serum albumin (BSA) polyethylene (PE) films at stages photodegradation. Circular dichroism fluorescence studies revealed that BSA undergoes structural rearrangement accommodate changes polymer's surface characteristics (i.e., crystallinity oxidation state) occur as result how structure may inform docking whole organisms, studied biofilm formation bacteriaShewanella oneidensison photodegraded PE. Interestingly, biofilms preferentially formed on PE correlated with state weathering induced most significant BSA. Taken together, our work suggests there are optimal physical chemical properties polymers predict which will carry biochemical or hitchhikers.
