Chemical compound and disease context of MSR1

 

Biological context of MSR1

  • To date, germline mutations have been found in three candidate genes for hereditary prostate cancer: ELAC2 at 17p11, RNASEL at 1q25 and MSR1 at 8p22 [13].
  • We observed significant differences in ELAC2, RNASEL, and MSR1 allele frequencies by race [14].
  • These proteins interact with the cytoplasmic domain directly and may have an effect on the functions of MSR such as internalization, cell-surface expression, and signal transduction [15].
  • Nevertheless, the low frequencies of deleterious alleles, in addition to an apparently moderate penetrance, does not support MSR1 as a major susceptibility gene in this family sample [16].
  • Further studies may focus on alternative mechanisms through which the MSR1 gene might be inactivated, such as aberrant DNA methylation, and/or pursue analyses of other genes on 8p21-23 for mutational events [2].
 

Anatomical context of MSR1

 

Associations of MSR1 with chemical compounds

  • High glucose-enhanced SR-A expression was prevented by protein kinase C and NAD(P)H oxidase inhibitors as well as antioxidants [20].
  • The in vivo experiments demonstrated that peritoneal macrophages from streptozotocin-induced diabetic mice increased SR-A expression when compared with those from nondiabetic mice [20].
  • Inhibitors of tyrosine kinase dramatically reduced MSR-induced protein tyrosine phosphorylation and PKC activity [21].
  • Our observations point to the conclusion that the reduction of SR-A expression and activity in presence of alpha-tocopherol is possibly related to its direct action on cell signaling [22].
  • Interestingly, gamma-tocopherol, which is a homologue of alpha-tocopherol with a comparable antioxidative capacity, showed only a weak suppression of SR activity, SR-A expression and AP-1 activity [22].

Other interactions of MSR1

 

Analytical, diagnostic and therapeutic context of MSR1

  • Meta-analyses revealed significant associations of prostate cancer with MSR1 IVS7delTTA, -14,742 A>G, and Arg293X in European Americans; Asp174Tyr in African Americans; RNASEL Arg462Gln in European American's overall and in family history-negative disease; and Glu265X in family history-positive European Americans [14].
  • In this context, we evaluated the association of germ-line mutations and common MSR1 sequence variants with prostate cancer risk in a case control study of a community-based sample of 134 African-American men with prostate cancer and 340 unaffected controls [30].
  • Nevertheless, the panel of intronic PCR primer pair sequences presented here will facilitate future studies to determine the full spectrum and frequency of genetic events that may affect expression/activity of the MSR1 gene in human tumors [2].
  • We have cloned an 80-kilobase human MSR gene and localized it to band p22 on chromosome 8 by fluorescent in situ hybridization and by genetic linkage using three common restriction fragment length polymorphisms [31].
  • Metabolic labeling/immunoprecipitation experiments showed that most of the macrophage scavenger receptor protein expressed by P388D1 cells was the N-glycosylated type II receptor; only small amounts of type I receptor were detected [32].
