How to Build CHD@ZJU

CHD related Articles were retrieved from Pubmed, by entering keywords "coronary heart disease" and constrict the publish date from 2000/1/1 to now (2013/1/23). As a result, totally 115898 articles were found and their abstracts were downloaded for text mining. Since some articles didn't contain abstracts, only 88396 abstracts remained.
The text-mining process to get CHD related genes could be divided in to 5 following steps:

  • 1) Extracting all keywords from abstracts and ignoring those keywords start with numbers. 101402 keywords were extracted.

    •
  • 2) Input these keywords into Gene library in ArrayTrack and find possible related genes. 4674 genes were then found.

  • 3) Put these 4674 genes again into pubmed abstracts to find related aticles. Only genes which offical name or there keyword description (such as prolactin for gene PRL) could be found in the abstract would be remained. As a result, 1247 genes were remained.

    •
  • 4) Manually examined on the 1247 genes to validate it was acutally related to CHD. Some genes would be filtered if it represents other meanings (such as gene CAD, Entrez ID:790, carbamoyl-phosphate synthetase 2, is mostly meant coronary arterial disease in articles). 681 genes were then validated with at least one reference.

  • 5) All genes was compared with 1078 CHD genes in RGD database, and 370 genes were overlapped. These 370 genes were labels as "RGD_Supported" and the other 293 genes were labels as "REFERED". All 663 genes had supported references in CHD@ZJU which were examined by step 4.

  • Abstract:"The single nucleotide polymorphisms (SNPs) apolipoprotein E (APOE) epsilon3/epsilon2/epsilon4, cholesteryl ester transfer protein (CETP) TaqIB, and apolipoprotein C3 (APOC3) -482 C>T have been associated with an atherogenic lipid profile and, in some studies, with increased cardiovascular risk. However, no data exist on their combined impact on atherosclerotic disease. We therefore aimed at investigating the combined impact of these SNPs on the presence of angiographically determined coronary artery disease (CAD). Genotyping was performed in 557 consecutive Caucasian patients undergoing coronary angiography for the evaluation of CAD. From the individual SNPs, only the APOE epsilon3epsilon4/epsilon4epsilon4 genotype was significantly associated with an increased risk of significant coronary stenoses with lumen narrowing >or=50% (odds ratio (OR)=1.77 [1.16-2.71]; p=0.008). However, the risk of CAD strongly increased when more than one of the analysed genetic variants was present: ORs were 2.74 [1.29-5.83]; p=0.009 for patients with both the APOE epsilon3epsilon4/epsilon4epsilon4 and the CETP B1B1 genotype, 1.97 [1.06-3.66]; p=0.031 for patients with both the APOE epsilon3epsilon4/epsilon4epsilon4 genotype and the APOC3 -482T allele, 2.12 [1.31-3.44]; p=0.002 for patients with both the CETP B1B1 genotype and the APOC3 -482T allele, and 3.99 [1.57-13.79]; p=0.029 for patients with all three variants. Multivariate analyses confirmed these results. We conclude that there are strong synergistic effects of the APOE epsilon3/epsilon2/epsilon4, the CETP TaqIB, and the APOC3 -482 C>T polymorphisms on their association with CAD."
