Disease relevance of Ddit3

 

Psychiatry related information on Ddit3

  • We suggest that CHOP-10 is a negative modulator of the activity of C/EBP-like proteins in certain terminally differentiated cells, similar to the regulatory function of Id on the activity of MyoD and MyoD-related proteins important in the development of muscle cells [4].
 

High impact information on Ddit3

  • CHOP-10 is induced upon differentiation of 3T3-L1 fibroblasts to adipocytes, and cytokine-induced dedifferentiation of adipocytes is preceded by the loss of nuclear CHOP-10 [4].
  • Thus, heterodimers of CHOP-10 and C/EBP-like proteins are unable to bind their cognate DNA enhancer element [4].
  • Coimmunoprecipitation of CHOP-10 and LAP from transfected COS-1 cells demonstrated a direct interaction between the two proteins, in vivo [4].
  • A 32P-labeled LAP DNA-binding and dimerization domain "zipper probe" was used to isolate a clone that encodes a new C/EBP-homologous protein: CHOP-10 [4].
  • We conclude that ER overload in beta cells causes ER stress and leads to apoptosis via Chop induction [5].
 

Chemical compound and disease context of Ddit3

  • Gadd45 and Gadd153 messenger RNA levels are increased during hypoxia and after exposure of cells to agents which elevate the levels of the glucose-regulated proteins [1].
  • Hypoxia (1% O2) strongly increased reactive oxygen species generation, hypoxia-inducible factor-1 and CHOP-10/GADD153 expression, and inhibited adipocyte differentiation [6].
 

Biological context of Ddit3

  • Role of C/EBP homologous protein (CHOP-10) in the programmed activation of CCAAT/enhancer-binding protein-beta during adipogenesis [7].
  • In support of these findings, up-regulation of CHOP-10 with the protease inhibitor N-acetyl-Leu-Leu-norleucinal prevents activation of C/EBPbeta, expression of C/EBPalpha, and adipogenesis [7].
  • As preadipocytes reach S phase, CHOP-10 is down-regulated, apparently releasing C/EBPbeta from inhibitory constraint and allowing transactivation of the C/EBPalpha gene [7].
  • The absence of P58(IPK) resulted in increased expression levels of two ER stress-inducible genes, BiP and Chop, consistent with the enhanced eIF2alpha phosphorylation in the P58(IPK) deletion cells [8].
  • Accordingly, CHOP10, a transcription factor induced early in response to ER stress, and the pleiotropic Clusterin, involved in protein folding, were also overexpressed [9].
 

Anatomical context of Ddit3

 

Associations of Ddit3 with chemical compounds

 

Regulatory relationships of Ddit3

  • Dominant-negative CHOP-10 is initially expressed by growth-arrested preadipocytes and sequesters/inactivates C/EBPbeta by heterodimerization with its leucine zipper [15].
  • Moreover, an exaggerated Gadd153 response to stress induced by ER stress agents was observed in PS1 mutant cells [16].
  • We now report that Epo markedly upregulates chop (gadd153) expression and that this transcription factor plays a role in erythropoiesis [17].
 

Other interactions of Ddit3

  • The induction of caspase-11 by LPS was suppressed in Chop knockout mice [18].
  • Focusing on this latter event highlights Ddit3, Timm8b and Oazin as potential new injury-induced molecular actors involved in a stress response pathway [19].
  • Urea treatment (100-300 mM) increased expression of the oxidative stress-responsive transcription factor, Gadd153/CHOP, at the mRNA and protein levels (at >/=4 h) in renal medullary mIMCD3 cells in culture, whereas other solutes did not [12].
  • An abnormality in the translational regulation of Gadd153 may sensitize cells to the detrimental effects of ER stress and contribute to the pathogenic actions of PS1 mutations in FAD [16].
  • The accumulation of p53, induction of p21, gadd45, and gadd153, and arrest of the cell cycle in G1 and G2 occurred normally [20].
