Project description:Fungi are ubiquitous in the environment and, like bacteria, are an integral part of the gut microbiome. However, unlike bacteria, fungal species that can stably colonize the murine gut and model commensal behavior remain elusive. Here, we show that Kazachstania pintolopesii, a dominant fungus found in pet store mice from geographically distinct regions, stably colonized laboratory mice. K. pintolopesii outcompeted other fungi and maintained stable colonization independent of gut bacteria. We find that K. pintolopesii does not induce a typical antifungal response in murine hosts locally in the gut or upon systemic challenge. Accordingly, K. pintolopesii colonization did not afford protection against systemic fungal infection by Candida albicans. Instead, K.pintolopessii colonization increased type 2 immune responses in the intestine and protected mice against helminth infection.
Project description:Triple-negative breast cancer (TNBC) is the most aggressive form of breast cancer due to lack of effective targeted therapies. Here, we report that the expression of miR-4417 is suppressed during the progression of TNBC cells from non-malignant to the malignant stage. miR-4417 is localized to chromosome 1p36, a region with high loss of heterozygosity in multiple cancers, and its biogenesis is DICER-dependent. Low expression of miR-4417 is significantly associated with worse prognosis in TNBC patients, while overexpression of miR-4417 is sufficient to inhibit migration and tumorigenecity of TNBC cells in vitro. Overall, our findings suggest that miR-4417 exerts a tumor suppressive effect and thereby could serve as a prognostic biomarker and therapeutic tool against TNBC. We used microarrays to profile the global miRNA changes during EMT to identify putative tumor suppressors and prognostic biomarkers for TNBC.

Project description:This is genome-scale metabolic model of Saccharomyces cerevisiae as the representative yeast species for the clade Saccharomycetaceae. This model was generated through homology search using a fungal pan-GEM largely based on Yeast8 for Saccharomyces cerevisiae, in addition to manual curation. This model has been produced by the Yeast-Species-GEMs project from Sysbio (www.sysbio.se). This is model version 1.0.0 accompanying the publication (DOI: 10.15252/msb.202110427), currently hosted on BioModels Database (http://www.ebi.ac.uk/biomodels/) and identified by MODEL2109130010.
