on the transcriptional activity induced by Smad3 In order to examine the mechanism by which Dex suppresses TGF-β–Smad3 pathways, we investigated whether Dex affects the transcriptional activity induced by TGF-β as well as Smad3 in MC3T3-E1

). The effects of E 2 and raloxifene on the expression of TERT Since the telomerase activity is known to be modulated by regulation of the level of telomerase catalytic subunit (TERT) at both the transcriptional and post-transcriptional levels

compartmentalization of SP1 in GT1-7 cells. To test this hypothesis, we evaluated KISS1 gene transcription levels in response to adiponectin, as well as AMPKα1-SiRNA, 5-aminoimidazole-4-carboxamide riboside (AICAR), and Compound C, which regulate the activity of AMPK
