Fibroblast growth factor 2 positively regulates expression of activating transcription factor 4 in osteoblasts [PDF]
Our previous studies showed that basic fibroblast growth factor 2 (FGF2) null mice display markedly reduced bone mass and bone formation. However, the mechanism by which FGF2 regulates bone mass or bone formation is not fully defined. Activating transcription factor 4 (ATF4), one member of activating transcription factor/cAMP response element binding ...

Effect of leucine on endoplasmic reticulum stress induced by early weaning in the liver of piglets
To investigate the effects of dietary leucine supplementation on endoplasmic reticulum (ER) stress in the liver of early-weaning piglets, we explored the morphology of liver cells, expression pattern of ER stress-associated proteins, and effects on ER ...

Activating transcription factor-4 promotes mineralization in vascular smooth muscle cells. [PDF]
Emerging evidence indicates that upregulation of the ER stress–induced pro-osteogenic transcription factor ATF4 plays an important role in vascular calcification, a common complication in patients with aging, diabetes, and chronic kidney disease (CKD).

Phosphorylation of Serine 114 of the transcription factor ABSCISIC ACID INSENSITIVE 4 is essential for activity [PDF]
Abstract The transcription factor ABA-INSENSITIVE(ABI)4 has diverse roles in regulating plant growth, including inhibiting germination and reserve mobilization in response to ABA and high salinity, inhibiting seedling growth in response to high sugars, inhibiting lateral root growth, and repressing light-induced gene ...

Function of the upstream activating factor in chromatin structure organization and transcriptional regulation at the yeast ribosomal DNA [PDF]
Chromatin is the template of all processes involved in DNA metabolism in the eukaryotic cell. Accordingly, chromatin is a dynamic structure which changes in its composition and posttranslational modification correlating with the functional state of a ...

Activating transcription factor 4 and X box binding protein 1 of Litopenaeus vannamei transcriptional regulated white spot syndrome virus genes Wsv023 and Wsv083. [PDF]
In response to endoplasmic reticulum (ER) stress, the signaling pathway termed unfolded protein response (UPR) is activated. To investigate the role of UPR in Litopenaeus vannamei immunity, the activating transcription factor 4 (designated as LvATF4 ...

Variable structure motifs for transcription factor binding sites [PDF]
Background: Classically, models of DNA-transcription factor binding sites (TFBSs) have been based on relatively few known instances and have treated them as sites of fixed length using position weight matrices (PWMs).

An R2R3 MYB transcription factor associated with regulation of the anthocyanin biosynthetic pathway in Rosaceae [PDF]
Background The control of plant anthocyanin accumulation is via transcriptional regulation of the genes encoding the biosynthetic enzymes. A key activator appears to be an R2R3 MYB transcription factor.
