Disease relevance of CPO

  • Population genetic and embryologic studies suggest that cleft palate only (CPO) may be a distinct clinical entity from cleft lip with or without cleft palate (CL/P) [1].
  • Mutational screening was performed in infants with nonsyndromic CPO or CL/P who were identified by the Iowa Birth Defects Registry [1].
  • BACKGROUND:: Nonsyndromic cleft lip with or without cleft palate (CL/P) or cleft palate only (CPO) are orofacial clefts and have a multifactorial etiology [2].
 

High impact information on CPO

  • The CP on chromosome 2 is predicted to cleave substrates with C-terminal acidic residues and was named CPO [3].
  • 9t,11t-conjugated linoleic acid was detected in the liver tissue and colonic mucosa of rats fed the CPO-containing diet [4].
  • Also, the effect of CPO on the fatty acid composition of liver tissue and colonic mucosa, the serum levels of total cholesterol and triglyceride, and the mRNA expression of cyclooxygenase (COX)-2 in the colonic mucosa were measured [4].
  • In the present study, we investigated whether dietary administration with CPO affects the development of azoxymethane (AOM)-induced colonic aberrant crypt foci (ACF) in male F344 rats to elucidate its possible cancer chemopreventive efficiency [4].
  • The indices of cell proliferation and apoptosis in the colonic mucosa of rats treated with AOM and 1% CPO have significant differences when compared with the AOM alone group [4].
 

Biological context of CPO

 

Associations of CPO with chemical compounds

  • Additionally, dietary administration with CPO decreased the serum triglyceride level and the expression of COX-2 mRNA in the colonic mucosa [4].
  • Catalpa (Catalpa ovata) seed oil (CPO) is a unique oil that contains a high amount of 9trans,11trans,13cis-conjugated linolenic acid [4].
  • Being a boy (OR, 2.0; 95% CI, 1.4-3.0), folic acid supplementation (OR, 0.6; 95% CI, 0.4-0.9), and low paternal education (OR, 1.6; 95% CI, 1.0-2.3) mainly determined CL/P in the multivariate analyses, compared to low paternal (OR, 4.5; 95% CI, 2.1-9.4) and maternal medication use (OR, 2.0; 95% CI, 1.0-4.0) for CPO [2].
