tokens: Using a natural dominant negative for AP-1 transcriptional activity in ROS 17 / 2 .8 cells , we then showed that AP-1 transcription factors mediated TGF-beta1- and BMP-2 regulated expression of the ( alpha1 ) collagen I gene as well as TGF-beta1 regulated expression of the parathyroid hormone ( PTH ) / PTH related peptide ( PTHrP ) receptor .
