Project description:In the present study, the eggs of Chinese pond turtles (Mauremys reevesii) were incubated at three temperatures (26℃, 29℃ and 32℃). During the thermosensitive period (TSP) of incubation, the adrenal-kidney-gonad (AKG) complexes were sampled, and a comprehensive investigation for miRNAs was performed using next-generation small RNA sequencing.

During the thermosensitive period (TSP) of incubation, the adrenal-kidney-gonad (AKG) complexes were sampled, and the transcriptome differences of the AKG samples were investigated using next-generation sequencing, then candidate genes associated with temperature-dependent sex determination of Reeves' Turtle were identified.
Project description:We report the expression profiles of putative genes involved in temperature-dependent sex determination across multiple developmental stages in turtles, and contrast this data with equivalent stages in turtles with sex chromosomes
Project description:Pain management is an important issue in veterinary medicine, requiring biomarkers with high sensitivity and specificity for the timely and effective treatment. Emerging evidence suggests that miRNAs are promising pain-related markers. The aims were to profile the circulating miRNA signature in plasma of turtles (Trachemys scripta) and point out potential candidate biomarkers of pain. Plasma of female turtles underwent surgical gonadectomy were collected 24h pre-surgery, and 2.5h and 36 h post-surgery. The expression of miRNAs was profiled by Next Generation Sequencing and the dysregulated miRNAs were validated using RT-qPCR. The diagnostic value of miRNAs was calculated by ROC curves.
Project description:An European eel-specific microarray platform was developed to identify genes involved in response to pollutants. A comparative analysis of gene expression was conducted between European eel Anguilla anguilla individuals from lowly-polluted Wijmeers pond at Uitbergen (Belgium), highly-polluted Hazewinkel pond at Willebroek (Belgium), extremely-polluted Dessel-Schotel canal at the locations of Schotel (Belgium) and low polluted Bolsena lake (Italy) environments.
Project description:Western painted turtles (Chrysemys picta bellii) are the most anoxia-tolerant tetrapod. Survival time improves at low temperature and during ontogeny, such that adults acclimated to 3oC survive far longer without oxygen than either warm-acclimated adults or cold-acclimated hatchlings. Since protein synthesis is rapidly suppressed to save energy at the onset of anoxia exposure, this study tested the hypothesis that cold-acclimation would evoke preparatory changes in protein expression that would support enhanced anoxia survival in adult but not hatchling turtles. The relative abundances of 1316 identified proteins were compared between temperatures and developmental stages.
Project description:Using iChIP, we map H3K27Ac, H3K4me3 and H3K4me1 in small populations (HSPCs) in the presence or absence of Med12 and identify affected super-enhancers. iChIP was performed using previously published protocols (Lara-Astiaso et al, 2014 Immunogenetics. Chromatin state dynamics during blood formation - Science, 345, 6199) Examination of histone modification in mouse HSPCs with and without Med12

Gene expression profiling was performed using an European eel-specific oligo-DNA microarray (GPL15124) of 14,913 probes based on single-colour detection (Cyanine-3 only). Microarrays were scanned with Agilent scanner G2565BA (barcode on the left, DNA on the back surface, scanned through the glass) at a resolution of 5 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. Feature Extraction (FE) 9.5 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.
