## Abstract **Scope:** Metabolic phenotyping promises to be a useful tool in human intervention studies. This study examined whether metabolic phenotyping could identify responders to vitamin D supplementation in terms of the metabolic syndrome. **Methods and results:** In a doubleβblind, randomis

β¦ Synopsis
Tetrahymena themphila is a ciliated protozoan studied by investigators from a wide range of disciplines as a model system for a variety of specialized eukaryotic cell functions. The proteinaceous secretory products of T thermophila have been isolated and characterized [l] and in this study we identify the major secretory product, a 34,000 Mr polypeptide, and use an antiserum prepared against this secretory protein to (1) demonstrate that this 34,000 Mr polypeptide is truly a secreted protein in Tetruhymena and (2) monitor the synthesis and transport of this protein by indirect immunofluorescence and light microscopy during mucocyst biogenesis.

The process of metastasis is a complex process involving numerous steps, and it is thought that cells able to complete all of these steps and form metastatic foci form a unique subpopulation of cells within the tumor. To study this metastatic subpopulation, a marker for the metastatic cells is requi
