Project description:Whole blood was collected as part of monthly veterinary checkups of bottlenose dolphins housed at Dolphing Quest in Waikoloa, Hawaii, USA. Gene expression from 5 samples was analyzed for comparison to the blood transcriptome of the beluga whale.

Project description:Brown algae (Phaeophyceae) are complex photosynthetic organisms with a very different evolutionary history to green plants, to which they are only distantly related. These seaweeds are the dominant species in rocky coastal ecosystems and they exhibit many interesting adaptations to these, often harsh, environments. The brown algae are also important because they are one of only a very small number of eukaryotic lineages that have evolved complex multicellularity. This work used whole genome tiling array approach to generate a comprehensive transcriptome map of the filamentous seaweed Ectocarpus siliculosus (Dillwyn) Lyngbye, a model organism for the brown algae. Keywords: high-resolution tiling array, brown algae, ectocarpus

Project description:Shewanella algae (S. algae), an emerging opportunistic pathogen, has been increasingly associated with severe gastrointestinal infections, particularly among immunocompromised individuals, including those with colorectal adenomas. To evaluate its potential role in the progression of colorectal adenomas, we conducted both in vivo and in vitro studies. In the in vivo model, mice bearing adenomas were orally administered S. algae to simulate natural ingestion. Concurrently, macrophages were exposed to S. algae in vitro to assess cellular responses. Oral administration of S. algae was found to exacerbate intestinal inflammation and increase colorectal adenoma burden. Transcriptomic analyses revealed elevated levels of reactive oxygen species (ROS) and upregulated expression of acyl-CoA synthetase long-chain family member 4 (Acsl4), indicative of enhanced iron metabolism and lipid peroxidation, key features of ferroptosis. Furthermore, the expression of key ferroptosis suppressors, including glutathione peroxidase 4 (Gpx4) and solute carrier family 7 member 11 (Slc7a11), was significantly downregulated. These pathological changes were effectively reversed upon treatment with ferrostatin-1 (Fer-1), a specific inhibitor of ferroptosis. In vitro experiments corroborated the in vivo findings, demonstrating consistent activation of ferroptotic pathways in macrophages. Collectively, these results suggest that S. algae may promote the progression of colorectal adenomas by inducting ferroptosis in both colonic tissues and macrophages. Therefore, therapeutic strategies targeting ferroptosis may offer a promising approach for managing high-risk individuals infected with S. algae, potentially improving clinical outcomes and quality of life.

Project description:The Streptophyta include unicellular and multicellular charophyte green algae and land plants. Colonization of the terrestrial habitat by land plants was a major evolutionary event that has transformed our planet. So far lack of genome information on unicellular charophyte algae hinders our understanding of the origin and the evolution from unicellular to multicellular life in Streptophyta. This work reports the high-quality reference genome and transcriptome of Mesostigma viride, a single-celled charophyte alga with a position at the base of Streptophyta. There are abundant segmental duplications and transposable elements in M. viride, which contribute to a relatively large genome with high gene content compared to other algae and early diverging land plants. This work identifies the origin of genetic tools that multicellular Streptophyta have inherited and key genetic innovations required for evolution of land plants from unicellular aquatic ancestors. The findings shed light on the age-old questions of the evolution of multicellularity and the origin of land plants.
