Disease relevance of Ces1

  • We demonstrate that each of these ONYX-015-based adenoviruses expresses an active CE enzyme that can efficiently convert CPT-11 to SN-38 [1].
  • However, in contrast to CPT-11, a water-soluble CPT analogue that was recently approved for second line treatment of colorectal cancer, the 20(S)-glycinate esters do not require carboxylesterase for conversion to their active forms [2].
  • Reversal of CPT-11 resistance of lung cancer cells by adenovirus-mediated gene transfer of the human carboxylesterase cDNA [3].
  • Cell toxicity induced by inhibition of acyl coenzyme A:cholesterol acyltransferase and accumulation of unesterified cholesterol [4].
  • Genetic analyses identified Ses1 as a significant quantitative trait locus influencing the carrier state of 129S6 mice following a sublethal challenge with Salmonella enterica serovar Enteritidis [5].
 

High impact information on Ces1

  • Finally, we demonstrate that we can achieve transgene expression and activity in vivo in a human tumor xenograft model, and that treatment with a CE-expressing virus in combination with CPT-11 enhances survival of tumor-bearing mice [1].
  • AdCMV.CE infection resulted in an increase in functional CE protein in resistant cells in vitro that was sufficient to convert CPT-11 to its active metabolite, SN-38, and effectively suppressed resistant cell growth in vitro in the presence of CPT-11 [3].
  • N-terminal amino acid sequence analysis indicated that the isolated enzyme was rat serum carboxylesterase [6].
  • Similarly, the nonacetylated derivative, N-(deoxyguanosin-8-yl) benzidine, was synthesized by carboxylesterase treatment of N-(deoxyguanosin-8-yl)-N'-acetylbenzidine and was shown not to occur in rat and mouse liver DNA [7].
  • Identification, expression, and purification of a pyrethroid-hydrolyzing carboxylesterase from mouse liver microsomes [8].
 

Chemical compound and disease context of Ces1

 

Biological context of Ces1

 

Anatomical context of Ces1

  • Mouse peritoneal macrophages (MPMs) or J774 macrophages were loaded with cholesteryl esters using acetylated LDL and FC/phospholipid dispersions and were subsequently exposed to an acyl coenzyme A:cholesterol acyltransferase (ACAT) inhibitor [17].
  • The model foam cells were then incubated for up to 5 days with an acyl-coenzyme A:cholesterol acyltransferase (ACAT) inhibitor (CP-113,818) in the absence of an extracellular FC acceptor to allow intracellular accumulation of FC [18].
  • To determine the chromosome location of the largest unmapped linkage group in the rat (LG V containing multiple carboxylesterase loci), we used single-strand conformation polymorphism analysis to identify the rat esterase-10 gene in a panel of rat x mouse somatic cell hybrids [16].
  • The loss in carboxylesterase activity correlated with decreased immunodetectable hydrolase A in microsomes incubated with VC, PMSF, or PMSF and VC [19].
  • All cell types of the respiratory epithelium had some carboxylesterase activity, with varying intensities between individual cell populations [20].
 

Associations of Ces1 with chemical compounds

  • We further demonstrate that feeding mice with diets containing cholestyramine or sodium cholate increases mRNA-expression of ES-x in liver 2.5- to 3-fold [13].
  • 9. Treatment with endoglycosidase H caused an increase in electrophoretic mobility indicating that the liver carboxylesterase was a glycoprotein of the high mannose type [21].
  • A second carboxylesterase gene (NCBI accession number NM_133960), isolated during a cDNA mouse liver library screening, was also found to hydrolyze pyrethroids [8].
  • Treating Y-1 cells with the acyl coenzyme A:cholesterol acyltransferase inhibitor, 58-035, caused cellular cholesteryl ester depletion and rendered more apparent the effect of dibutyryl-cAMP to cause cellular free cholesterol depletion [22].
  • Male mice were treated (i.p.) for 3 days with 15 different environmentally encountered epoxides, and the effects of these compounds on liver microsomal and cytosolic epoxide hydrolase (mEH and cEH), glutathione S-transferase (mGST and cGST) and carboxylesterase (mCE) activities were determined [23].
