Disease relevance of Scarb1

 

High impact information on Scarb1

 

Biological context of Scarb1

  • The class-B type-I scavenger receptor (SR-BI) plays a key role in cholesterol homeostasis; it mediates the selective uptake of lipoprotein cholesterol to steroidogenic tissues [7].
  • SR-BI gene expression was high in steroid-producing tissues and in the liver, consistent with a role of this receptor in the uptake of HDL cholesterol [8].
  • The results of these studies demonstrate that the rat HDL receptor SR-BI promoter contains two sterol response elements (pSRE and dSRE) through which SREBP-1a can bind and activate transcription of this gene [9].
  • The rat and human SR-BI genes were mapped to a region previously linked between rat and human chromosomes 12 [8].
  • The chromosomal locations of the rat and human SR-BI homologs suggest that this gene is a new member of a previously reported, conserved synteny group [8].
 

Anatomical context of Scarb1

 

Associations of Scarb1 with chemical compounds

  • Differential regulation of steroid hormone biosynthesis in R2C and MA-10 Leydig tumor cells: role of SR-B1-mediated selective cholesteryl ester transport [12].
  • Furthermore the expression of SR-BI mRNA in the ovary is stimulated by LH and cyclic AMP (cAMP) [13].
  • Class B scavenger receptor type I (SR-BI), a candidate for the PS receptor, was detected in Sertoli cells [6].
  • The treatment of theca-interstitial cells with anti-SR-BI antibody blocked more than 90% of HDL plus human chorionic gonadotropin-stimulated androstenedione production, and selective HDL-CE uptake [14].
  • Sterol regulatory element-binding protein-1a binds to cis elements in the promoter of the rat high density lipoprotein receptor SR-BI gene [9].
