. 1989 b ). Cell-type specific expression of the POMC gene in corticotropes and melanotropes is maintained by the expression of Tpit (also called Tbx19), a Tbox family transcription factor, and pituitary homeobox 1 (Pitx1), a homeoprotein transcription

sensitive to inhibition by cycloheximide ( Kolek et al . 2005 , Haussler et al . 2010 ), suggesting that the transcriptional effect may be secondary and dependent on the induction of an intermediary transcription factor. However, the time course of FGF23

-dependent transcription factors. By modulating the transcription of target genes in response to ligand, TRs play key physiological roles in the regulation of many aspects of development, growth and metabolism, including the regulation of mitochondrial activity ( Flamant

Introduction Thyroid hormones (TH) exert profound effects on metabolism and growth. Most of TH actions occur through the nuclear TH receptors (TRs), which are ligand-dependent and ligand-independent transcription factors ( Yen 2001 ). TRs are

Introduction The adrenal cortex of mammals produces cortisol (or corticosterone) as glucocorticoid and aldosterone as mineralocorticoid. The function of these steroids is ultimately specified by the transcription factors (glucocorticoid and

Tyr 1138 engages the STAT3 transcription factor. LepRb→STAT3 signaling represents the primary mechanism by which leptin regulates energy balance, although the target genes of STAT3 in LepRb neurons remain undiscovered. Leptin also recruits the IRS2→PI

transcription factor 7-like 2 (TCF7L2), which has its binding site in the G2 enhancer element of proglucagon ( G lu ), a precursor of GLP1 ( Akiyama 2000 ). Insulin enhances GLP1 production via inhibition of glycogen synthase kinase (GSK)-3β
