Regulation of mdr1b gene expression in Fischer, Wistar and Sprague-Dawley rats in vivo and in vitro.

abstract：:Integrins control the cell attachment to the extracellular matrix and play an important role in mediating cell proliferation, migration and survival. A number of important cancer-associated integrin genes can be regulated by microRNAs (miRNAs) that bind to their target sites in the 3' untranslated regions. We examined...
