Understanding microRNAs regulation in heat shock response in the sea cucumber Apostichopus japonicus

Project description:In this study, we sought to determine the expression profiles of miRNAs under HS in A. japonicus by using HiSeq techinique. Nine miRNA libraries of sea cucumbers (Control: C1, C2, C3; HS 6h: 6h1, 6h2, 6h3; HS 48h: 48h1, 48h2, 48h3 ) were sequenced respectively. We highlighted differentially expressed miRNAs among HS groups, many of which were invovled of immunity process and disease regulation.

Understanding the Heat Shock Response in the Sea Cucumber Apostichopus japonicus, Using iTRAQ-Based Proteomics.

Project description:The sea cucumber Apostichopus japonicus is exploited as a commercial species owing to their high nutritive and medicinal value. Recent high summer temperatures have caused high mortality rates in A. japonicus. In this study, we applied the isobaric tag for relative and absolute quantitation (iTRAQ) technique to investigate the global protein expression profile under an acute short-term (48 h) heat stress. In total, 3432 proteins were identified, and 127 proteins showed significant heat stress responses, with 61 upregulated proteins and 66 downregulated proteins. Our results suggest that heat stress influenced the expression of proteins involved in various biological processes, such as tissue protection and detoxification, lipid and amino acid metabolism, energy production and usage, transcription and translation, cell apoptosis, and cell proliferation. These findings provide a better understanding about the response and thermo-tolerance mechanisms of A. japonicus under heat stress.

Differential expression of genes in the respiratory tree of sea cucumber (Apostichopus japonicus) under normal dissolved oxygen and hypoxia conditions

Project description:The sea cucumber Apostichopus japonicus is a deposit-feeder and vital for marine benthic ecosystems. Hypoxia lasting for several days can lead to massive mortality in A. japonicus. It is important to understand the molecular responses of A. japonicus when exposed to acute changes in DO concentration. In the present study, RNA-seq provided a general overview of the gene expression profiles of the respiratory tree of A. japonicus exposed to dissolved oxygen (DO) of 8 mg/L (DO8), 4 mg/L (DO4) and 2 mg/L (DO2) conditions.

Large-scale identification and comparative analysis of miRNA expression profile in the respiratory tree of the sea cucumber Apostichopus japonicus during aestivation (part 2)

Project description:The sea cucumber Apostichopus japonicus withstands high water temperatures in the summer by suppressing metabolic rate and entering a state of aestivation. We hypothesized that changes in the expression of miRNAs could provide important post-transcriptional regulation of gene expression during hypometabolism via control over mRNA translation. The present study analyzed profiles of miRNA expression in the sea cucumber respiratory tree using Solexa deep sequencing technology. We identified 279 sea cucumber miRNAs, including 15 novel miRNAs specific to sea cucumber. Animals sampled during deep aestivation (DA; after at least 15 days of continuous torpor) were compared with animals from a non-aestivation (NA) state (animals that had passed through aestivation and returned to an active state). We identified 30 differentially expressed miRNAs ([RPM (reads per million) >10, |FC| (|fold change|) ≥1, FDR (false discovery rate) <0.01]) during aestivation, which were validated by two other miRNA profiling methods: miRNA microarray and real-time PCR. Among the most prominent miRNA species, miR-124, miR-124-3p, miR-79, miR-9 and miR-2010 were significantly over-expressed during deep aestivation compared with non-aestivation animals, suggesting that these miRNAs may play important roles in metabolic rate suppression during aestivation.
