We demonstrate the first programmed transport of live yeast (Saccharomyces cerevisiae) and a zebrafish embryo (Danio rerio) within droplets in a two-plate digital microfluidic device. The yeast remained viable after transport, and the actuated droplets left no yeast behind. A zebrafish embryo transported 2 hours after fertilization developed normally and hatched. Dechorionation was demonstrated by mixing a droplet of digestive reagent droplet with a droplet containing the embryo. These results demonstrate the potential for using a droplet microfluidic device as an alternative to microwell plates for yeast and zebrafish assays.

Maintenance of neural progenitors requires Notch signaling in vertebrate development. Previous study has shown that Jagged2-mediated Notch signaling maintains proliferating neural progenitors in the ventral spinal cord. However, components for Jagged-mediated signaling remain poorly defined during late neurogenesis.

Background: Lovastatin, the main lipid-lowering component in red yeast rice, is a golden anti-lipid drug, but its long-term application is continuously challenged by potential skeletal muscle atrophy. Daidzein, an isoflavone derived from soybeans and many Chinese medicines, shows therapeutic potential in treating muscle-related diseases and metabolic disorders. However, whether daidzein can improve lovastatin-induced muscle atrophy and the specific mechanism needs to further study.

Triple-negative breast cancer (TNBC) is known for its aggressive nature, typically presenting as high-grade tumors that grow and spread quickly in all breast cancer types. Several studies have reported a strong correlation between cancer and microbial infections due to a compromised immune system. The most frequent infection associated with surface malignancies, including breast cancer, is Candidiasis, which is majorly caused by .

In exploring a growing demand for innovative approaches to tackle emerging and life threatening fungal diseases, we identified long-chain 4-aminoquinoline (4-AQ) derivatives as a new class of anti-virulence agents. For the first time, we demonstrated that 4-AQs effectively prevent filamentation of Candida albicans, a key virulence trait, under multiple triggering conditions. Selected 4-AQ derivatives inhibited filament formation in a zebrafish model of disseminated candidiasis at 1.

Yeast serves as a functional alternative and sustainable protein source in aquaculture. This protocol outlines feeding strategy and intestinal proteome analysis of zebrafish (Danio rerio), using S-trap for digestion, iTRAQ, and mass spectrometry for protein quantification. Additionally, it details the analysis of chemical components in feed and functional assessments via Kyoto Encyclopedia of Genes and Genomes (KEGG), Eukaryotic Orthologous Group (KOG), and Gene Ontology (GO).
