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:"A previous genetic analysis of the Cholesterol and Recurrent Events (CARE) trial found that carriers of the 719Arg allele of the kinesin family member 6 gene (KIF6) (rs20455), but not noncarriers, received significant event reduction from pravastatin therapy. However, that previous analysis of CARE included only Caucasian patients and was limited to the myocardial infarction components of the primary end point. Therefore, the aim of this study was to investigate whether pravastatin therapy reduced primary end point events in KIF6 719Arg carriers and noncarriers, separately, in the combined ethnic groups of CARE. The effect of pravastatin therapy on primary end point events (fatal coronary event or nonfatal myocardial infarction) was investigated in Cox regression models that adjusted for population structure using either self-reported ethnicity or the principal components of genetic heterogeneity. After adjustment for age, gender, and self-reported ethnicity, pravastatin therapy reduced events in carriers of KIF6 719Arg (hazard ratio [HR] 0.63, 95% confidence interval [CI] 0.49 to 0.83) but not in noncarriers (HR 1.01, 95% CI 0.69 to 1.45) (p for interaction = 0.049). After adjustment for age, gender, traditional risk factors, and principal components, pravastatin therapy reduced events in carriers of 719Arg (HR 0.64, 95% CI 0.49 to 0.85) but not in noncarriers (HR 0.90, 95% CI 0.62 to 1.32) (p for interaction = 0.14). In conclusion, in an analysis that included CARE patients of all ethnic groups, pravastatin therapy significantly and substantially reduced primary end point events in carriers of the KIF6 719Arg allele but not in noncarriers."
