Metabolomic and transcriptomic investigations reveal the responses of cucumber leaves exposed to polystyrene nanoplastics (PSNPs)

ABSTRACT:

The uptake and accumulation of nanoplastics by plants have raised particular concerns. However, molecular mechanisms underlying nanoplastic phytotoxicity are still vague and insufficient. Thus, its potential environmental risks and biosafety are receiving increased attention. In this study, cucumber plants were exposed to polystyrene nanoplastics (PSNPs) under different concentration. The results demonstrated that phenotypic parameters (total photosynthetic pigment content, relative membrane permeability, total phenolic content, and lipid peroxidation) were not significantly affected. However, metabolomic and transcriptomic analysis revealed that both doses of PSNPs induced the expression regulation of different key genes, exhibiting considerable distinction on metabolic responses in cucumber. The high dose of PSNPs induced stronger alteration in cucumber leaves than low dose of PSNPs. Low dose exposure significantly affected four metabolic pathways involved in the carbohydrate metabolism. High dose exposure significantly affected five metabolic pathways involved in the carbohydrate metabolism and four metabolic pathways involved in the amino acid metabolism. These findings shed new light on the phytotoxic mechanism and environmental implication behind the interaction of nanoplastics and plants, and advance our understanding of the potential adverse effect induced by the presence of nanoplastics in agricultural systems.

Polystyrene nanoplastics (PSNPs, <100nm), an artificial pollutant that is widespread in the environment, can be assimilated by plants to alter plant gene expression and its metabolic pathway; thus, interfering with physiological homeostasis and growth of plants. Recently, the biosafety and potential environmental risks of PSNPs have attracted enormous attention. However, the knowledge regarding the uptake and phytotoxicity of atmosphere PSNPs subsiding to plant leaves is still limited. Here, we ...[more]

Project description:Cadmium is a natural element that can accumulate to toxic levels in the environment leading to detrimental effects in animals and humans including kidney, liver and lung injuries. Using a transcriptomics approach, genes and cellular pathways affected by a low dose of cadmium were investigated. Adult largemouth bass were intraperitoneally injected with 20 Âµg/kg of cadmium chloride and microarray analyses were conducted in the liver and testis 48 hours after injection. Transcriptomics profiles identified in response to cadmium treatment were tissue-specific with the most differential expression changes found in the liver tissues, which also contained much higher levels of cadmium than the testes. Acute exposure to a low dose of cadmium induced oxidative stress response and oxidative damage pathways in the liver. The mRNA levels of antioxidants such as catalase increased and numerous transcripts related to DNA damage and DNA repair were significantly altered. Hepatic mRNA levels of metallothionein, a proposed marker of cadmium exposure, showed a small insignificant increase after 48 hours exposure. Carbohydrate metabolic pathways were also disrupted in cadmium-exposed fish with hepatic transcripts such as UDP-glucose pyrophosphorylase 2 and sorbitol dehydrogenase highly induced. Both tissues exhibited a disruption of steroid signalling pathways. In the testis, estrogen receptor beta and transcripts linked to cholesterol metabolism were suppressed. On the contrary, genes involved in cholesterol metabolism were highly increased in the liver including genes encoding for the rate limiting steroidogenic acute regulatory protein and the catalytic enzyme 7-dehydrocholesterol reductase. Integration of the transcriptomics data using functional enrichment analyses revealed a number of enriched gene networks associated with previously reported adverse outcomes of cadmium exposure such as liver toxicity and impaired reproduction. Adult largemouth bass (n=4 per treatment) were ip injected with a single dose of cadmium chloride (20 ug/kg) or a saline solution. After 48 hours, liver and testis were excised and differential gene expression profiles were examined.

Project description:Genomic, proteomic, and metabolomic technologies continue to receive increasing interest from environmental toxicologists. This interest is due to the great potential of these technologies to identify detailed modes of action and to provide assistance in the evaluation of a contaminant?s risk to aquatic organisms. Our experimental model is the zebrafish (Danio rerio) exposed to reference endocrine disrupting compounds in order to investigate compound-induced changes in gene transcript profiles. Adult, female zebrafish were exposed to 0, 15, 40, and 100 ng/L of 17 alpha-ethynylestradiol (EE2) and concentration and time-dependent changes in hepatic gene expression were examined using Affymetrix GeneChip® Zebrafish Genome Microarrays. At 24, 48, and 168 hours, fish were sacrificed and liver mRNA was extracted for gene expression analysis (24 and 168 hours only). In an effort to link gene expression changes to effects on higher levels of biological organization, body and ovary weights were measured and blood was collected for measurement of plasma steroid hormones (17 beta-estradiol (E2), testosterone (T)) and vitellogenin (VTG) using ELISA. EE2 exposure significantly affected GSI, E2, T, VTG and gene expression. We observed 1575 genes that were significantly affected (up- or down-regulated by at least 1.5-fold (p ? 0.001) in a concentration-dependent manner by EE2 exposure at either 24 or 168 hours. EE2 exposure altered transcription of genes involved in steroid hormone homeostasis, cholesterol homeostasis, retinoic acid metabolism, and cell growth and proliferation. Plasma VTG was significantly increased at 24, 48, and 168 hours (p<0.05) at 40 and 100 ng/L and at 15 ng/L at 168 hours. E2 and T were significantly reduced following EE2 exposure at 48 and 168 hours. GSI was decreased in a dose-dependent manner at 168 hours. In this study, we identified genes involved in a variety of biological functions that have the potential to be used as markers of exposure to estrogenic substances. Future work will evaluate the use of these genes in zebrafish exposed to weak estrogens to determine if these genes are indicative of exposure to estrogens with varying potencies.
