Project description:The European clam, Ruditapes decussatus (Linnaeus, 1758) is a bivalve mollusc of the family Veneridae native to the European Atlantic and Mediterranean coastal waters. Its production is exclusively based on natural recruitment, which is subject to high annual fluctuations due to adversely affected by pollution and other environmental factors. A microarray-based analysis was performed with the objectives of describe genomic feature of oocytes and identify potential markers of oocyte quality in the economically important European clam, Ruditapes decussatus. The oocytes of a total of 25 females from Ria de Aveiro, Western coast of Portugal, were selected for this study and their quality was estimated by early developmental success until D-larval rate, under controlled conditions.

Project description:The European clam, Ruditapes decussatus (Linnaeus, 1758) is a bivalve mollusc of the family Veneridae native to the European Atlantic and Mediterranean coastal waters. Its production is exclusively based on natural recruitment, which is subject to high annual fluctuations due to adversely affected by pollution and other environmental factors. Microarray analyses have been performed in four gonadal maturation stages of two higly productive Portuguese wild populations (Ria Formosa in South and Ria de Aveiro in North) characterized by different responses to spawning induction.

Project description:The European clam, Ruditapes decussatus (Linnaeus, 1758) is a bivalve mollusc of the family Veneridae native to the European Atlantic and Mediterranean coastal waters. Its production is exclusively based on natural recruitment, which is subject to high annual fluctuations due to adversely affected by pollution and other environmental factors. Microarray analyses have been performed in four gonadal maturation stages of two higly productive Portuguese wild populations (Ria Formosa in South and Ria de Aveiro in North) characterized by different responses to spawning induction. Twenty clams (Ruditapes decussatus)were monthly sampled between July 2011 and July 2012 in two different Portuguese wild populations: Ria Formosa and Ria de Aveiro. At each sampling date the gonads of the collected clams were immediately dissected for RNA extraction and fixed for histological analysis. Total RNA was isolated using Extract-all (Eurobio) procedure. RNA quality and integrity was controlled on the Agilent bioanalyzer using RNA nanochips and Agilent RNA 6000 nanoreagents (Agilent Technologies, Waldbronn, Germany). RNA concentrations were measured at 260 nm using a ND-1000 spectrophotometer (Nanodrop Technologies) using the conversion factor 1 OD = 40 mg/mL total RNA. Samples were stored at -80°C until further use. Gene expression profiling was performed using an R.decussatus oligo-DNA microarray of 59,951 probes based on single-colour detection (Cyanine-3 only). Microarrays were scanned with Agilent scanner G2565BA at a resolution of 2 microns; all slides were scanned twice at two different sensitivity settings (XDRHi 100% and XDRLo 10%); the scanner software created a unique ID for each pair of XDR scans and saved it to both scan image files. FeatureExtraction v10.7.3.1 used XDR ID to link the pairs of scans together automatically when extracting data. The signal left after all the FE processing steps have been completed is ProcessedSignal that contains the Multiplicatively Detrended, Background-Subtracted Signal.

Project description:The European clam, Ruditapes decussatus (Linnaeus, 1758), is a bivalve mollusc of the family Veneridae native to the European Atlantic and Mediterranean coastal waters. Its production is exclusively based on natural recruitment, which is subject to high annual fluctuations due to adversely affected by pollution and other environmental factors. In the present study, oocytes from 15 females were collected in Ria de Aveiro (Western coast of Portugal) and microarray analysis was performed in order to investigate gene expression profiles characterizing naturally released oocytes and ovarian oocytes obtained by stripping. Released oocytes were obtained in the context of a study carried out by de Sousa and co-workers (GSE54954: de Sousa et al., 2014, submitted) focusing on expression profiles characterizing oocytes with different quality level. In particular, to compare stripped and spawned oocytes, a total of 10 samples (5 with bad/intermediate hatching rate and 5 with good hatching rate) out of the 25 analyzed in the previous study (GSE54954), and 5 new pools of stripped oocytes, have been analyzed by microarray analyses.
