Project description:Despite the fact that deep sea mining is becoming more popular nowadays in terms of obtaining metals ores for daily life purposes, its potential impact to the deep sea habitat, which is originally stable and converse, stills remains uncertain. In order to estimate and regulate the imapct of deep sea mining activities, an in-situ exposure experiment is performed to observe the change in proteomics expression of the deep-sea scvangers, Abyssorchomene distinctus, to copper exposure. This project aims to suggest a potenial protein bio-marker in Abyssorchomene distinctus to assess the impact of mining activities towards deep sea organisms and also discuss the potential application of other deep sea in-situ exposure experiment in the future.

Project description:Colonization of deep-sea hydrothermal vents by invertebrates was made efficient through their adaptation to a symbiotic lifestyle with chemosynthetic bacteria, the primary producers of these ecosystems. Anatomical adaptations such as the establishment of specialized cells or organs have been evidenced in numerous deep-sea invertebrates. However, very few studies detailed global inter-dependencies between host and symbionts in these ecosystems. In this study, we proposed to describe, using a proteo-transcriptomic approach, the effects of symbionts on the deep-sea mussel Bathymodiolus azoricus’ molecular biology. We induced an in situ depletion of symbionts and compared the proteo-transcriptome of the gills of mussels in three conditions: symbiotic mussels (natural population), symbiont-depleted mussels and aposymbiotic mussels

Project description:Parasites of the genus Perkinsus spp. cause high mortalities and economic losses to the most noticeable bivalves produced in the worldwide aquaculture. In this study, we analyze how P. olseni influences the gene expression profiles of hemocytes from Manila clam (Venerupis philippinarum) using experimental infections along a temporal series and a Manila clam immune-enriched DNA microarray. Healthy and Perkinsus-infected clams (V. philippinarum) were obtained from Carril and Pontevedra shellfish farms, respectively (Galicia, NW Spain). The presence-absence of P. olseni was confirmed using the Ray`s fluid thioglycollate medium assay (RFTM) (Ray, 1966). Healthy clams were maintained in an open circuit filtered sea water tanks at 15°C with aeration. Natural infected animals were maintained in the same conditions using closed circuit sea water. All animals were fed daily with a mixture of microalgae containing Phaeodactylum tricornutum, Isochrysis galbana and Rhodomonas lens. Clams were acclimatized to the aquarium conditions for one week before the experiments were conducted. Perkinsus trophozoites were isolated from naturally infected animals following the protocol established by Ford et al., (2002). The concentration was adjusted to 5x104 trophozoites /ml in filtered sea water (FSW). Healthy clams (P. olseni free animals) (n=100) with a weight of 2.25 ± 0.64 g soft tissue, were notched in the shell and intramuscularly injected with 100 µl of the trophozoites suspension. Control animals (n=100) were injected with 100 µl of FSW. After infection, clams were maintained in 50 l tanks with aeration.Twenty animals from each experimental group and time point were sampled at 5, 10, 14, and 31 days post infection (pi).Hemolymph were extracted to perform microarrays experiments. In each condition hemolymph from three five individuals was pooled. Total RNA isolation was conducted following the manufacturer’s specifications. Isolated RNAs were treated with DNase I and purified again using the RNeasy Mini kit (Qiagen). A 8x15K Agilent 60-mer oligo-microarray (GPL16450) was used to compare gene expression profiles of clams after P. olseni infection with uninfected animals. The Agilent Feature Extraction Software (version 9.5.1) was used for the data extraction and background subtraction following standard procedures. The GeneSpring software (Agilent) was used to normalize and analyze the microarray fluorescence data.
