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:"Coronary artery disease (CAD) has become a major health problem in many countries because of its increasing prevalence and high mortality. Recently, an association of a functional sequence variation, -8C>G, in the human proteasome subunit alpha type 6 gene (PSMA6) with the susceptibility to CAD was reported. To validate the association, we investigated a total of 1330 cases and 2554 controls from Japanese and Korean populations for PSMA6 genotypes, and no evidence of the association was obtained in both Japanese (odds ratio (OR)=1.03, 95% confidence interval (CI); 0.90-1.19, P=0.66, allele count model) and Korean populations (OR=1.00, 95% CI; 0.86-1.17, P=0.95, allele count model). However, when a meta-analysis of data from this study and previously reported six replication studies was done, OR was 1.08 for the G allele (95% CI; 1.02-1.14, P=0.0057), suggesting that the contribution of PSMA6 to CAD was not large enough to be readily replicated. Further studies are required to establish the contribution of this variant in the susceptibility to CAD."
