To investigate this process, we established three-dimensional (3D) epithelial culture model systems using Fischer rat thyroid (FRT) cells or murine primary thyrocytes that developed polarized spherical structures with a central lumen mimicking thyroid follicles. Using microarray-based differential expression analysis of FRT cells grown under 2D or 3D conditions followed by RNA-mediated interference (RNAi) and morphogenetic analysis, we identified a key role for the thyroid transcription factor Pax8 and its target Cadherin-16 (Cdh16) in the generation of polarized follicle-like structures. Silencing Pax8 expression inhibited the acquisition of apical-basal membrane polarity and impaired lumen formation. Both laminin and \u03b21-integrin (Itgb1) expression was reduced, while cell cytoskeleton polarized distribution was altered. Silencing Cdh16 expression also led to the formation of defective structures characterized by very low laminin expression at the follicle-matrix interface, down-regulation of Itgb1, and unpolarized distribution of cell cytoskeleton. Our results demonstrate that Pax8 controls apical-basal follicular polarization and follicle formation through Cdh16.<\/jats:p>","DOI":"10.1242\/jcs.184291","type":"journal-article","created":{"date-parts":[[2016,10,25]],"date-time":"2016-10-25T22:59:26Z","timestamp":1477436366000},"source":"Crossref","is-referenced-by-count":26,"title":["Pax8 controls thyroid follicular polarity through Cadherin-16"],"prefix":"10.1242","author":[{"given":"Petrina","family":"Koumarianou","sequence":"first","affiliation":[{"name":"Instituto de Investigaciones Biom\u00e9dicas \u201cAlberto Sols\u201d.
