Algae mostly occur either as unicellular (microalgae) or multicellular (macroalgae) species, both being uninucleate. There are important exceptions, however, as some unicellular algae are multinucleate and macroscopic, some of which inhabit tropical seas and contribute to biocalcification and coral reef robustness. The evolutionary mechanisms and ecological significance of multinucleation and associated traits (e.g., rapid wound healing) are poorly understood. Here, we report the genome of <i>Ha ...[more]

Acute effects of high pCO2 and hypoxia on gene expression in blue rockfish (Sebastes mystinus)

Project description:We sequenced complementary DNA created from white muscle messenger RNA in juvenile blue rockfish and performed a differential gene expression analysis to describe the fishes' responses to the global change-related stressors of high pCO2 (low pH) and hypoxia (low dissolved oxygen, DO). To examine gene expression over ecologically realistic timescales that emulate the duration of spring upwelling events in the California Current ecosystem, we collected and sequenced samples after 12 h, 24 h and two weeks of exposure to four treatments: control (pH≈8.0, pCO2≈400μatm, DO≈8 mg/L), high pCO2 (pH≈7.6, pCO2≈1200μatm, DO≈8 mg/L), hypoxic (pH≈8.0, pCO2≈400μatm, DO≈4 mg/L), and combined high pCO2/hypoxic (pH≈7.6, pCO2≈1200μatm, DO≈4 mg/L).

Proteomic responses to varying temperatures in a calcareous green macroalga

Project description:Genus Halimeda is a worldwide distributed reef-building organism facilitated by fast growth and a rapid turnover rate in tropical and sub-tropical oceans. It is an excellent candidate for calcareous algae research because its calcification occurs extracellular, which deposits aragonite in the semi-enclosed inter-utricle space. In this study, we sampled the thalli of Halimeda macroloba in Sanya Bay of the South China Sea. The mean winter and summer water temperatures in Sanya Bay were 25.05℃ and 28.72℃, respectively. Additionally, the mean surface and bottom layer water temperatures in summer were 29.61℃ and 27.23℃. In order to simulate the natural temperature range, a factorial experimental design with three treatments (25°C, 28°C, and 31°C) was set. The goal of this study was to decipher the underlying traits that may facilitate H. opuntia to maintain high productivity and active physiology under different temperatures. Here, we employed iTRAQ-based quantitative proteomics and untargeted metabolomics approaches to investigate the protein and metabolite profiles of H. macroloba.

Differential proteomic analysis in a host–parasite interaction of host cells infected with Toxoplasma gondii

Project description:Toxoplasma gondii, a representative model organism of the phylum Apicomplexa, can infect almost all warm-blooded organisms including humans. Invasion of host cells in a host–parasite interaction is the key step necessary for T. gondii to complete its life cycle. Here, we investigate global proteomic changes based on TMT analysis in both the host cells (human foreskin fibroblasts, HFFs) and T. gondii during intracellular infection. A total of 3477 and 1434 proteins were quantified, of which 378 and 1100 proteins were differentially expressed (p-value<0.05 and ≥1.5-fold change)in Homo sapiens and T. gondii proteins, respectively. In HFF cells, Gene Ontology (GO) and KEGG pathway analyses revealed a large number of differentially expressed proteins (DEPs) enriched in metabolic processes and immune-associated signaling pathways, such as NF-κB, cAMP, and Rap1 signaling pathways. T. gondii DEPs involved in pathway analysis and GO annotations included cellular protein metabolic process, peptide metabolic process, and peptide biosynthetic processes and indicated that cell biosynthesis and metabolism were increased during T. gondii infection. These findings reveal new proteomic differences in the parasite–host interaction during T. gondii infection.

TMT-based quantitative proteomics reveals the protective mechanism of Tenuigenin after experimental intracerebral hemorrhage in mice

Project description:Tenuigenin (TNG), an extract obtained from Polygalae Radix, possesses anti-inflammatory,anti-oxidant, neuro-protective properties. However, the potential mechanism of TNG on intracerebral hemorrhage (ICH) has not been well studied. Therefore, in this study, we aimed to identify the prospective mechanism of TNG in treating ICH with the help of TMT-based quantitative proteomics. Our results showed that the optimal dose of TNG was 16mg/kg, which could markedly improve neurological functions, reduce cerebral edema, hematoma volume and hemoglobin level 72h after ICH. Furthermore,our proteomic results identified that a total of 404 DEPs (353 up and 51 down regulated) were identified in ICH+vehicle vs Sham group, while 342 DEPs (306 up and 36 down regulated) and 76 DEPs (28 up and 48 down regulated) were quantified in TNG vs Sham group and TNG vs ICH+vehicle group respectively. In addition, a total of 26 DEPs were selected out according to strict criteria. Complement and coagulation cascades was the most significantly enriched pathway and two proteins (MBL-C and Car1) were further validated as hub molecules.

Project description:In this study, an integrative analysis of the gill-specific proteome at 0 h, 12 h and 36 h after alkalinity stress was performed to identify important regulators and pathways involved in alkalinity adaption of Exopalaemon carinicauda. This study reveals the first time-course, gill-specific, combined proteomic profiling associated with alkalinity adaption of E. carinicauda and provides new insights into the mechanisms underlying the molecular response to alkalinity stress in shrimp.
