  • Title: Chemical screening methods for flagellar phenotypes in Chlamydomonas.
    Author: Avasthi P, Marshall WF.
    Journal: Methods Enzymol; 2013; 525():351-69. PubMed ID: 23522478.
    Abstract:
    Cilia and flagella are important organelles used for sensing the external cellular environment or for motility. Abnormalities in ciliary structure or function can have devastating pathological consequences ranging from sinusitis and obesity to polycystic kidney disease, retinal degeneration, and mental retardation. Chlamydomonas flagella are excellent models to study the regulation and normal function of cilia. We utilized the 1280 compound Sigma LOPAC annotated library to screen for phenotypes in Chlamydomonas flagellar length, motility, deflagellation, and cellular toxicity. Phenotypes were assessed by quantitation from direct microscopic visualization and custom-designed motility/viability assays. Compounds were clustered based on data across all assays to facilitate the identification of novel pathways regulating flagella in Chlamydomonas. These methods can both aid our understanding of the basic biology of flagellar regulation and provide useful points of therapeutic intervention for cilia-related disorders.
