Project description:Two different early developmental stages of gilthead sea bream: i) larvae at 24 hours post-hatching ( Stage 1), and ii) larvae at 96 hours post-hatching (Stage 4), were used for gene expression analysis. For each stage, total RNA was extracted from five (5) independent biological replicates, each consisting of pools of approximately 40-50 larvae. Based on SAM analysis, 1518 genes were differentially expressed between the two stages with a FDR (False Discovery Rate) of 0.0.

Project description:Purpose: Analysis of exosomal miRNA in plasma of patients with metastatic and non-metastatic pancreatic cancer. To identify exosomes cargo specific miRNAs promoting cancer metastasis. Methods: We divide the plasma samples into five groups according to whether they have metastasis and undergo surgery.The five groups are Health(20),Metastasis Pre-operation and Post-operation (14),Non-metastasis Pre-operation and Post-operation(9).Then we collected the exosomes by ultracentrifugation and extracted the small RNA in each sample.Then, we analyzed the expression changes of miRNA by small RNA sequencing. Result: Different groups have different expression of small RNA. Compared with the non-metastatic group, the expression of miR-92a-3p , miR-148-3p and miR-25-3p increased in the metastatic group. Conclusion:Exosomal miRNA in pancreatic cancer patient derived plasma were analyze using Hiseq2500 sequencing technique. We identified that miR-92a-3p, miR-148-3p and miR-25-3p enriched in metastatic pancreatic cancer patient plasma derived exosomes.

Project description:Goal: To determine the effects of capture-release events in wild dolphins (Tursiops truncatus). Methods: An analysis of the Peripheral Blood Leukocyte (PBL) transcriptome was conducted on a group of 20 animals. The samples were collected in 2 different locations along the US east coast (Charleston, SC; Indian River Lagoon, FL) and 2 blood samples were collected for each dolphin 1) immediately after the capture event (*pre*) and 2) just before the animal was released (*post*). In between *pre* and *post* blood collections (30-40 minutes) additional samples were collected from the animals for physiological, chemical and biochemical analysis. RNA extracted from *pre* and *post* blood samples was used for micorarray hybridizations and transcriptome analysis using a species-specific PBL cDNA microarray (Mancia *et al*., 2007).

Project description:Among the parasites of insects, endoparasitoids impose a costly challenge to host defenses because they use their host’s body for the development and maturation of their eggs or larvae, and ultimately kill the host. Tachinid flies are highly specialized acoustically-orienting parasitoids that release first instar mobile larvae which burrow into the host’s body to feed. We investigated the possibility that Teleogryllus oceanicus field crickets employ post-infestation strategies to maximize survival when infested with the larvae of the parasitoid fly Ormia ochracea. Using crickets from the Hawaiian island of Kauai, where the parasitoid is present, and crickets from the Cook Islands (Mangaia), where the parasitoid is absent, we evaluated fitness consequences of infestation by comparing feeding behavior, reproductive capacity, and survival of males experimentally infested with O. ochracea larvae. We also evaluated genetic mechanisms underlying host responses by comparing gene expression in crickets infested with fly larvae for different lengths of time with that of uninfested control crickets. We observe some differences in fitness (spermatophore production) and survival (total survival time post-infestation) between populations. However, for both traits significant population effects 1) were not associated with the slope of the response to different numbers of larvae and 2) only emerged from models containing body condition at one but not both time points evaluated. Gene expression patterns also revealed population differences in response to infestation. We did not find evidence for consistent differences in genes associated with immunity or stress response. Taken together, these results suggest that coevolution with the fly does not strongly select for either post-infestation resistance or tolerance of parasitoid larvae in male crickets.

Based on SAM analysis, 1518 genes were differentially expressed between the two stages with a FDR (False Discovery Rate) of 0.0. In this study, we analyzed the gene expression profiles of two early developmental stages of gilthead sea bream using Agilent-016251 Sparus aurata Oligo Microarray platform (10 arrays, no replicate) based on single-colour detection (Cyanine-3 only). Microarrays are 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 are scanned twice at two different sensitivity settings (XDRHi 100% and XDRLo 10%); the scanner software creates a unique ID for each pair of XDR scans and saves it to both scan image files. Feature Extraction 9.5 uses 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:Platelets contain non-coding RNAs (ncRNAs), and their measurement may complement aggregometry. In the community-based Bruneck Study (N = 338), we conducted over 2,700 aggregometry measurements and over 65,000 RT-qPCR measurements in platelet releasates, platelet-poor plasma and isolated platelets. We show agonist-specific, dose-dependent platelet ncRNA release that is inhibited by aspirin. Collagen induces the strongest release for most ncRNAs, while miR-150 is hyperresponsive to ADP and miR-21 is hyperresponsive to arachidonic acid. Inflammation and high leukocyte-derived RNA content in platelets correlate inversely with platelet aggregation and platelet ncRNA release after stimulation. This inverse correlation is not observed in aspirin users. Finally, we reveal that platelet-derived microRNAs and YRNAs are carried by proteins and readily released, while circular RNAs, long non-coding RNAs and messenger RNAs are carried by vesicles and preferentially retained. Our findings provide evidence that inflammation leads to platelet pre-activation in vivo resulting in platelet exhaustion ex vivo.

Project description:Zebrafish eggs were collected at 28 °C, and split into three temperature groups (24 °C, 28 °C, 32 °C) for incubation. When larvae reaching first feeding, the incubation temperature of larvae from 24 °C and 32 °C was gadually changed to 28 °C, and all fish were kept at 28 °C for later development until adulthood. At 100 d post-fertilization, seven replicates from each group were intraperitoneally (i.p.) injected with 2 μl of 50 mg/ml lipopolysaccharide (LPS) from Pseudomonas aeruginosa 10, while another seven replicates were i.p. injected with 2 μl phosphate-buffered saline as control. At 12 h post-injection, the spleen was dissected, and total RNA was isolated. Five LPS-treated replicates and five controls were used for building small RNA libraries and sequencing. A total of 112 novel miRNAs were identified using miRDeep2. By comparing fish from different embryonic incubation tmeperatures, 32 miRNAs (29 up-/3 down-regulated) were identified differentially expressed (DEmiRs, adjusted p-value < 0.05, |fold change| > 2.0, DESeq2) in fish from embryonic incubation temperature of 32 °C compared to fish kept at constant 28 °C, 3 DEmiRs (2 up-/1 down-regulated) were identified in response to LPS in fish kept at 28 °C. A total of 9,116 target genes were predicted using miRanda (v3.3a), including 8,224 genes targeted by 32 DE miRNAs and 892 genes targeted by 3 DE miRNAs.
