Disease relevance of Crem

  • Overexpression of CREM-17X in intact islets via adenovirus infection decreased islet insulin mRNA levels and insulin content and resulted in a significant decrease in glucose- or KCl-induced insulin secretion [1].
 

High impact information on Crem

 

Biological context of Crem

 

Anatomical context of Crem

 

Associations of Crem with chemical compounds

 

Other interactions of Crem

  • These results suggest that retinoids function as a negative regulator of CREM expression in testes [6].
 

Analytical, diagnostic and therapeutic context of Crem

  • Northern blot analysis revealed a 5-fold increase in the abundance of CREM-17X mRNA and a concomitant 50% reduction in the insulin mRNA in FFA-treated islets [1].
  • In addition, RT-PCR analysis indicated that ATRA specifically represses the expression of the activator spliced variant of CREM (CREMtau) [6].
  • Consistent with an inhibitory effect of CREM on CRH transcription, chromatin immunoprecipitation assays in cells transfected with ICER I revealed recruitment of CREM by the CRH promoter in conjunction with decreases in Pol II association [5].
  • Using in situ hybridization with a cDNA fragment of the cAMP responsive element modulator (CREM) isoform inducible cAMP early repressor (ICER) we demonstrate a light-induced upregulation of CREM mRNA in rat SCN during the second half of the night [11].
  • Western blot analysis using CREM antibodies confirmed the RNA data [10].
