Project description:Harmful algal blooms are induced largely by nutrient enrichment common in warm waters. An increasingly frequent phenomenon is the “red tide”: blooms of dinoflagellate microalgae that accumulate toxins lethal to other organisms in high doses. Here, we present the de novo assembled genome (~4.75 Gbp) of Prorocentrum cordatum, a globally abundant, bloom-forming dinoflagellate, and the associated transcriptome, proteome, and metabolome data from axenic cultures to elucidate the microalgal molecular responses to heat stress. We discovered, in a high-G+C genome with long introns and extensive genetic duplication, a complementary mechanism between RNA editing and exon usage that regulates dynamic expression and functional diversity of genes and proteins, and metabolic profiles that reflect reduced capacities in photosynthesis, central metabolism, and protein synthesis. These results based on multi-omics evidence demonstrate the genomic hallmark of a bloom-forming dinoflagellate, and how the complex gene structures combined with multi-level transcriptional regulation underpin concerted heat-stress responses.

Project description:To identify the direct m6A demethylation targets of ALKBH5 at the onset of renal IRI, we performed methylated RNA immunoprecipitation sequencing (MeRIP-seq) and RNA sequencing (RNA-seq) using RNA isolated from IRI mouse kidney of WT and KO mice 24h after I/R (WT n=3 vs. KO n=3)

Project description:We examined, through an oligonucleotide microarray protocol, the renal differential transcriptome profiles of mices submitted to IRI, IPC and Hemin treatment. After identifying the profiles of differentially expressed genes observed for each comparison, we carried out functional enrichment analysis to reveal transcripts putatively involved in potential relevant biological processes and signaling pathways. The most relevant enriched biological processes found in these comparisons were stress, inflammation, apoptosis, pathways in cancer, differentiation, angiogenesis, focal adhesion, ECM-receptor interaction, ion transport, angiogenesis, mitosis and cell cycle, inflammatory response, olfactory transduction and regulation of actin cytoskeleton. In addition, the most important overrepresented pathways were MAPK, ErbB, JAK/STAT, Toll and Nod like receptors, Angiotensin II, Arachidonic acid metabolism, Wnt and coagulation cascade. Also, new insights were gained about the underlying protection mechanisms against renal IRI promoted by IPC and Hemin treatment. Venn diagram analysis allowed us to uncover common and exclusively differentially expressed genes between these two protective maneuvers, underscoring potential common and exclusive biological functions regulated in each case. In summary, IPC exclusively regulated the expression of genes belonging to stress, protein modification and apoptosis, highlighting the role of IPC in controlling exacerbated stress response. Treatment with the Hmox1 inducer Hemin, in turn, exclusively regulated the expression of genes associated with cell differentiation, metabolic pathways, cell cycle, mitosis, development, regulation of actin cytoskeleton and arachidonic acid metabolism, suggesting a pleiotropic effect for Hemin. According to surgery and treatment procedures, mices were divided into five groups: Control, Ischemia-reperfusion injury (IRI), animals pre-treated with Hemin followed by IRI (Hemin + IRI), animals only treated with Hemin (Hemin) and animals pre-conditioned and submitted to IRI (IPC+IRI). To identify the consequences of IRI, Hemin treatment or IPC in gene expression profiles, the following statistical comparisons were made between the groups: IRI vs Control, IPC+IRI vs Control, IPC+IRI vs IRI, IRI+Hemin vs IRI and Hemin vs Control.

Project description:Dinoflagellates are phytoplanktonic organisms found in both freshwater and marine habitats. They are often studied because related to harmful algal blooms responsible for impacts on ecosystem functioning, economic damages for aquaculture and fishery industries and/or deleterious impacts for human health. In addition they are also known to produce bioactive compounds, such as for the treatment of cancer or beneficial effects for the treatment of Alzheimer’s disease. The dinoflagellate Amphidinium sp. is a cosmopolitan dinoflagellate species known to produce both cytotoxic and beneficial compounds. However, several studies reported that environmental changes (e.g. nutrient starvation, UV radiation and ocean acidification) may alter this production. The aim of this study was to sequence the full transcriptome of the dinoflagellate Amphidinium carterae in both nitrogen- starved and -repleted culturing conditions (1) to evaluated its response to nitrogen starvation, (2) to look for possible polyketide synthases (PKSs), involved in the synthesis of various compounds, in this studied clone, (3) if present, to evaluate if nutrient starvation can influence PKS activity, (4) to test strain cytotoxicity on human cells and (5) to look for other possible enzymes/proteins of biotechnological interest.
