Polymer type specific microplastic effects on Dreissena bugensis’ proteome, antioxidant activity and behavior

ABSTRACT: The freshwater mussel Dreissena bugensis was exposed for nine days to different microplastic particles, in detail, to three petroleum-based polymers (polyamide (PA), polyethylene terephthalate (PET), polystyrene (PS)), to one bio-based polymer (polylactic acid (PLA)) and to ground mussel shells (MS), serving as a natural particle control (size range: 20-75 µm;1000 p ml-1). Behavior endpoints were analyzed with hall sensor based real-time valvometry. Additionally, biochemical alterations of ROS detoxifying enzymes were analyzed, and a proteomic profiling on digestive gland tissue was performed.

Insights into the digestive gland of Mytilus coruscus under heat stress using TMT-based proteomics

Project description:A healthy existence relationship between mussels and environment relies on suitable PH, adequate oxygen and suitable temperature. Besides ocean acidification, ocean warming has been shown to cause mussel dead, a phenomenon responsible for extensive mussel dead around the word. How heat stress impacts mussel alive is poorly understood. We founded that. The superoxide dismutase (SOD) activity of two treatment groups were significantly higher than that of control group, and the activity of acid phosphatase (ACP) was significantly higher in two treatment groups than control group. The lactate dehydrogenase (LDH) activity of 26 ℃ treatment group was significantly higher than that of control group, and the LDH activity of 33 ℃ treatment group was significantly lower than that of control group. Cellular content of lysozyme (LZM) was significantly higher in two treatment groups than control group. In this study, we applied TMT quantification to investigate how Mytilus coruscus responds to heat stress (26 ℃, 33 ℃). We identified 1652 to 1878 differentially expressed proteins (DEPs) from these heat conditions, among which 897 were commonly regulated by all the two temperature and were significantly enriched in nutrients digestion and absorption (e. g. fat digestion and absorption). Furthermore, proteins associated with nutrients metabolism, signaling pathways (p53 signaling pathway and MAPK signaling pathway)and energy metabolism (e. g. TCA cycle) were impacted, suggesting that the ability of basic metabolism of Mytilus coruscus may be altered by heat stress.

Spatial Regulation Dominates Gene Function in the Ganglia Chain

Project description:Spatial regulation analysis across multiple condition comparisons revealed distinct patterns of gene expression. We combined these transcriptome data with spatial CNS data to produce the spatio-transcripto map of the ganglia chain. The Hirudo Medicinalis set of transcripts generated here provides a resource for gene discovery and gene regulation within the nervous system. In addition, the strategy for de novo assembly of transcriptome data presented here may be helpful in other similar transcriptome studies. Examination of 3 different ganglia in 3 different leeches.

De Novo Transcriptome Sequencing for Tetramorium bicarinatum: The first comprehensive venom gland transcriptome analysis from an ant species.

Project description:In order to provide a global insight on the transcripts expressed in the venom gland of the Brazilian ant species Tetramorium bicarinatum and to unveil the potential of its products, high-throughput expressed sequence tags were generated using Illumina paired-end sequencing technology. A total of 212,371,758 pairs of quality-filtered, 100-base-pair Illumina reads were obtained. The de novo assemblies yielded 36,042 contigs for which 27,873 have at least one predicted ORF among which 59.77% produce significant hits in the available databases. The investigation of the reads mapping toxin class revealed a high diversification with the major part consistent with the classical hymenopteran venom protein signature represented by venom allergen (33.3%) followed by a diverse toxin-expression profile including several distinct isoforms of phospholipase A1 and A2, venom serine protease, hyaluronidase, protease inhibitor and secapin. Moreover, our results revealed for the first time the presence of toxin-like peptides that have been previously identified from unrelated venomous animals such as waprin-like (snakes) and agatoxins (spiders and conus). 300 ant specimens from the species Tetramorium bicarinatum were dissected in order to extract the RNA from their venom gland, The whole ant body was used as a reference,

Glycosidades of Pomacea canaliculata

Project description:In this study, liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) was applied to define the occurrence, diversity and origin of glycosyl-hydrolases along the digestive tract of P. canaliculata. Cellulases, hemicellulases, amylases, maltases, fucosidases and galactosidases were identified across the digestive tract. The digestive gland and the contents of the crop and style sac yield a higher diversity of glycosidase-derived peptides.

Gene Expression Defines Natural Changes in Mammalian Lifespan

Project description:Mammals differ more than hundred fold in maximum lifespan, which can be altered in either direction during evolution, but the molecular basis for natural changes in longevity is not understood. Divergent evolution of mammals also led to extensive changes in gene expression within and between lineages. To understand the relationship between lifespan and variation in gene expression, we carried out RNA-seq-based gene expression analyses of liver, kidney and brain of 33 diverse species of mammals. Our analysis uncovered parallel evolution of gene expression and lifespan, as well as the associated life history traits, and identified the processes and pathways involved. These findings provide direct insights into how Nature reversibly adjusts lifespan and other traits during adaptive radiation of lineages. RNA-seq gene expression profiling in normal liver, kidney and brain of 33 mammalian species.

Proteomics of marine mussels exposed to the toxic marine alga Prorocentrum lima

Project description:This project aimed to disclose the metabolic alterations and responses of the marine mussel Mytilus galloprovincialis after grazing the toxic microalga Prorocentrum lima. Mussels metabolic alterations were investigated by shotgun proteomics, during the phases of intoxication and depuration. The diarrhetic shelllfisf toxins were also quantified in this project, for assessing the levels of contamination of mussels.

Project description:In order to select genes that are differentially expressed in salivary glands during Ixodes ricinus infection by Bartonella henselae we compare the transcriptome of infected and non-infected salivary glands I. ricinus from a pathogen free colony were infected -or not- with B. henselae at the larval and then the nymphal stage and salivary glands of the resulting females adult were dissected for RNA extraction. 454 sequencing was performed on pooled conditions in order to obtain a reference databank. Infected and non-infected samples were then sequenced separatly with illumina, blaston teh reference datbank and compared.
