Glucocorticoid receptor positively regulates transcription of FNDC5 in the liver
Irisin is secreted by skeletal muscle during exercise and influences energy and metabolic homeostasis. This hormone is a cleaved and secreted fragment of fibronectin type III domain-containing 5 (FNDC5). Elucidation of the FNDC5 gene regulation mechanism is necessary to clarify the function of irisin as a potential therapeutic target in human metabolic diseases. Thus, we investigated the geneti...
متن کاملCommentary: The unliganded glucocorticoid receptor positively regulates the tumor suppressor gene BRCA1 through GABP beta
Loss of BRCA1 tumor suppressor function is a critical event in breast tumorigenesis. We have previously identified the stress hormone hydrocortisone as a negative regulator of BRCA1 expression in nonmalignant mammary cells. Here, we have identified a direct role for the unliganded glucocorticoid receptor (GR) in BRCA1 upregulation in the absence of hydrocortisone. The positive regulatory effect...
متن کاملThe RAV1 transcription factor positively regulates leaf senescence in Arabidopsis
Leaf senescence is a developmentally programmed cell death process that constitutes the final step of leaf development and involves the extensive reprogramming of gene expression. Despite the importance of senescence in plants, the underlying regulatory mechanisms are not well understood. This study reports the isolation and functional analysis of RAV1, which encodes a RAV family transcription ...
متن کاملPhysical measurements of the liver glucocorticoid receptor.
Physical measurements were made on the cytosolic form of the liver [3H]dexamethasone receptor. These include a Stokes radius of 3.5 nm, determined by gel filtration, and sedimentation coefficients of 5.1 and 7-8S, by sucrose-density-gradient centrifugation. From these measurements, the following physical properties were calculated: apparent mol. wt. 78000 (the 5.1 S form); D app. 6.1 X 10(-7) c...
متن کاملStimulation of transcription in vitro from a liver-specific promoter by human glucocorticoid receptor (hGRalpha).
The rat tyrosine aminotransferase (TAT) gene is a liver-specific and glucocorticoid-inducible gene. Previous studies have shown that the TAT promoter (TAT0.35; nt -350 to +1) is able to sustain liver-specific gene expression both in transient transfection and in a transcription assay in vitro [Schweizer-Groyer, Groyer, Cadepond, Grange, Baulieu and Pictet (1994) Nucleic Acids Res. 22, 1583-1592...
