AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2021; 239:105953. [PMID: 34521059 DOI: 10.1016/j.aquatox.2021.105953] [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: 01/04/2021] [Revised: 08/13/2021] [Accepted: 08/23/2021] [Indexed: 06/13/2023]
Abstract
The molecular mode of action underpinning the response of mollusks exposure to endocrine disrupting chemicals (EDCs) remains unclear due to a lack of available information regarding their genome. Single molecule real-time (SMRT) sequencing makes it possible to reveal molecular mechanisms by direct sequencing of full-length transcripts. In the present study, the transcriptome profile of the freshwater snail Parafossarulus striatulus after exposure to 17β-estradiol (E2) or 17α-methyltestosterone (MT) was evaluated using SMRT sequencing strategy. In total, 216,598 non-redundant and full-length gene isoforms were generated and 106,266 isoforms were predicted with a complete open reading frame (ORF). Moreover, 60.36% of the isoforms were matched to known proteins in at least one of six databases. Differential gene expression analyses showed significantly different patterns in paired samples with different treatments. The expression levels of several membrane receptor isoforms of P. striatulus including dopamine receptor (DR), FMRFamide receptor (FMRFaR), neuropeptide Y receptor (NYR) and neuropeptide FF receptor (NFFR), but not estrogen receptor (ER) or estrogen-related receptor (ERR), were significantly affected by E2 and MT. These findings suggest that activation of membrane receptors, as well as other signaling pathways, might be critical for mediating the effects of endocrine disruption in mollusks. The transcriptome information obtained from the SMRT sequencing provides a significant contribution to the investigation of the molecular mode of action of endocrine disrupting chemicals on P. striatulus.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 752:141942. [PMID: 32896793 DOI: 10.1016/j.scitotenv.2020.141942] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 08/19/2020] [Accepted: 08/22/2020] [Indexed: 06/11/2023]
Abstract
To evaluate the environmental impact of receiving water from the Qinghe River sewage treatment plant (STP) effluents in Beijing, we collected sediments and Bellamya aeruginosa (Up-site, Discharge-site, and Down-site) both in 2017 and 2018 and analyzed the samples via chemical analysis, biological responses and transcriptomics. In two years of data, our biological results showed that AChE activities presented different degrees of influence on B. aeruginosa captured at sampling points of the STP compared to control sites (P < 0.05). Additionally, indicators of the antioxidant system (e.g., SOD, CAT, GST, EROD activity) and MDA content were significantly increased in the whole tissue at the Up-site of the STP. Integration of the assessed biomarkers using the integrated biomarker response (IBR) index ranked the environmental impact at sites as Up-site > Discharge-site > Down-site. In terms of the transcriptome data, B. aeruginosa collected from the Discharge-site of the STP showed greater transcriptomic response than it did from all other sites. KEGG pathway analysis revealed that sewage significantly altered the expression of genes involved in xenobiotics by cytochrome P450, drug metabolism-cytochrome P450, glutathione metabolism, oxidative phosphorylation, citrate (TCA) cycle, glycolysis/gluconeogenesis, apoptotic and Parkinson's disease. The concentrations of 34 organic pollutants (17 PAHs, 10 PAEs, 7 EDCs) were measured. The chemical concentrations of pollutants decreased from Up-site to Down-site and were well correlated with enzyme activity, IBR, and transcriptomic results. Our results demonstrated that the combined use of chemical analysis, biological responses and transcriptome data is necessary to validate the efficacy of a battery of biomarkers chosen to detect environmental stress due to pollution.

Abstract
Many studies on the control of reproduction in mollusks have focused on hormones (and proteins associated with the production and signaling of those hormones) which were originally discovered in humans, in the belief that if they are also present in mollusks, they must have the same role. However, although human sex steroids can be found in mollusks, they are so readily absorbed that their presence is not necessarily evidence of endogenous synthesis. A homolog of the vertebrate nuclear estrogen receptor has been found in mollusks, but it does not bind to estrogens or indeed to any steroid at all. Antibodies against human aromatase show positive immunostaining in mollusks, yet the aromatase gene has not been found in the genome of any invertebrates (let alone mollusks). This review will deal with these and other examples of contradictory evidence for a role of human hormones in invertebrate reproduction.

Abstract
Gastropods are the largest and most diverse class of mollusc and include species that are well studied within the areas of taxonomy, aquaculture, biomineralization, ecology, microbiome and health. Gastropod research has been expanding since the mid-2000s, largely due to large-scale data integration from next-generation sequencing and mass spectrometry in which transcripts, proteins and metabolites can be readily explored systematically. Correspondingly, the huge data added a great deal of complexity for data organization, visualization and interpretation. Here, we reviewed the recent advances involving gastropod omics ('gastropodomics') research from hundreds of publications and online genomics databases. By summarizing the current publicly available data, we present an insight for the design of useful data integrating tools and strategies for comparative omics studies in the future. Additionally, we discuss the future of omics applications in aquaculture, natural pharmaceutical biodiscovery and pest management, as well as to monitor the impact of environmental stressors.

Abstract
Freshwater snails are promising bioindicators that can be used in ecotoxicological testing and ecological risk assessments. To screen molecular responses following mollusk exposure to algal blooms, whole transcriptome sequencing was performed with the freshwater snail (Parafossarulus striatulus) fed with blue algae (Microcystis aeruginosa). A total of 86,848 unigenes were assembled, and 10,413 unigenes were annotated in the TrEMBL, Pfam, KEGG, and SwissProt databases. In snails fed with both green and blue algae, a total of 276 differentially expressed unigenes were identified, though there were limited differences in snails fed with only green algae. In addition, ten randomly selected differentially expressed unigenes were analyzed in snails collected from Taihu Lake, China. The expression of four unigenes exhibited a trend consistent with that observed in transcriptome profiling of laboratory snails. The results of this study provide an invaluable resource for enhancing our understanding of ecotoxicology following the occurrence of algal blooms in lakes.

Abstract
Endocrine disrupting chemicals (EDCs) have the potential to affect development and reproduction in gastropods. However, one is today lacking basic understanding of the Molluscan endocrine system and one can therefore not fully explain these EDC-induced affects. Furthermore, only a few genes that potentially may be connected to the endocrine system have been sequenced in gastropods. An example is the estrogen receptor gene (er) that have been identified in a restricted number of freshwater and marine gastropods. Here, we have identified a new partial coding sequence of an estrogen receptor gene (er) in the European common heterobranch Radix balthica. The following phylogenetic analysis divided the ers of heterobranchs and ceanogastropods in two branches. Furthermore, exposure to the synthetic estrogen 17α-ethinylestradiol (EE2) showed that exposure could significantly affect er expression level in the heterobranch R. balthica. This paper is the first that phylogenetically compares gastropods' er, basal er expression profiles, and transcriptional estrogenic responses in gastropods from two different evolutionary groups.

Abstract
Expression levels of eight candidate reference genes were quantified in tissues of gastropod Bellamya aeruginosa exposed for 10 d to various stressors, including fasting, 17β-estradiol, 17α-methyltestosterone, and Cd(2+). The results showed that 18s rRNA was the most highly expressed of the candidate reference genes, while H2A was the least expressed. There were no significant changes (p>0.05) in the expression of the eight genes in tissues among the different treatments. Using RefFinder to evaluate the expression stabilities of the eight candidate reference genes, ribosomal protein was shown to be the most stable reference gene, and no effects were observed among the different stressor treatments. These results indicate that RPL 7 is the most suitable reference gene for quantifying gene expression in B. aeruginosa under environmental stress, which was verified in B. aeruginosa exposed to high doses of E2 for 24 and 72h.
