Distinct functions of HOXD proteins in regulation of cyclin and CDK expression.

<p>Immunoblot analysis of cyclin A2, cyclin B1 and CDK1 levels in BE(2)-C/Tet-Off/myc-HOXD cells cultured in the presence or absence of Doxy for 3 or 6 days. Alpha-tubulin levels are shown as loading control. Shown are representative of two independent experiments with similar results.
