Target Data

Function Involved in the transfer of neutral lipids, including cholesteryl ester and triglyceride, among lipoprotein particles. Allows the net movement of cholesteryl ester from high density lipoproteins/HDL to triglyceride-rich very low density lipoproteins/VLDL, and the equimolar transport of triglyceride from VLDL to HDL
Gene References into Functions
  1. Studied frequency of two genetic polymorphisms of cholesteryl ester transfer protein (CETP) in a Mongolian population with essential hypertension. PMID: 28425253
  2. The I405V polymorphism in the CETP gene is strongly associated with ischemic stroke in a Polish population. PMID: 30078763
  3. CETP may play an important role in the development of atherosclerosis mainly by decreasing HDL-C levels and increasing the accumulation of macrophage-derived foam cells PMID: 29317793
  4. Our results show an association of this CETP variant at position +82 on HDL cholesterol, levels and adiposity parameters in obese subjects with diabetes mellitus type 2 PMID: 29280647
  5. Results demonstrate that CETP expression reduced HDL and increased non-HDL fractions. Also, exercise training reduced CETP plasma levels. These results reinforce the positive metabolic effects of exercise, and resolved a controversy about CETP response to exercise PMID: 29058169

An association of cholesteryl ester transfer protein (CETP) TaqIB polymorphism with ischemic stroke (IS) was found in the 4 genetic models. In the subgroup analysis by ethnicity, similar risks were also observed in Asian population. CETP TaqIB polymorphism is associated with IS risk, and the B2 allele is a protective factor. PMID: 28648960
  8. The aggregation analysis revealed a higher correlation between siblings than between parent-offspring pairs representing the role of genetic factors in metabolic syndrome (MetS).

  18. Combined exposure to variants in the genes that encode the targets of CETP inhibitors and statins was associated with discordant reductions in LDL-C and apoB levels and a corresponding risk of cardiovascular events that was proportional to the attenuated reduction in apoB but significantly less than expected per unit change in LDL-C. PMID: 28846118
  19. Treatment of mildly hypercholesterolemic subjects with CETP inhibitor anacetrapib reduces Lp(a) levels by decreasing its production. PMID: 28729361

  21. Based on results from the study with a relatively large sample size, CETP may be the only detectable locus with common genetic variants that influence HDL-C response to statins substantially in individuals of European descent. Although CETP is known to be associated with HDL-C, the evidence is provided that this pharmacogenetic effect is independent of its association with baseline HDL-C levels. PMID: 27587472
  22. The rs1800775 [1.31 (1.22-1.42); p = 3.41E-12] in the CETP gene and rs359027 [1.26 (1.16-1.36); p = 2.55E-08] in the LMCD1 gene were significantly associated with LHDLC levels PMID: 26879886

  25. Since expression of CETP has been shown to be positively correlated with the risk of CAD, higher frequency of "A" allele (patients: 22.69% vs.controls: 13%) reveals that c.*84G>A is a risk factor for CAD in South Indians PMID: 27768712
  26. CETP V405V genotype was associated with significantly enhanced HDL levels (P = 0.03), mostly owing to the female sex (P = 0.46 for males, P = 0.02 for females), whereas LDL and triglyceride levels were unchanged. PMID: 27439317
  27. The single nucleotide polymorphisms in lipoprotein lipase, ApoA5, and CETP were associated with serum triglycerides and HDL-cholesterol levels, but not with coronary artery disease in Pakistani population under study. PMID: 28143480
  28. Elevated CETP blood concentration was risk factor for coronary artery disease and correlates with pre beta1-high-density lipoprotein. PMID: 28073362
  29. Results show that the bound cholesteryl esters intraconvert between bent and linear conformations in the CETP core tunnel as a consequence of the high degree of conformational flexibility of the protein. PMID: 27445332
  30. Daily consumption of policosanol for 8 weeks resulted in lowered blood pressure, reduced serum TG level and CETP activity, and elevated HDL-C contents. PMID: 28259941
