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:"Studies focusing on the association of gene methylthioadenosine phosphorylase (MTAP) with the risk of coronary artery disease (CAD) and myocardial infarction (MI) are limited. In this study, we explored the effects of rs10118757 in MTAP gene on CAD and MI by performing association analysis in a Chinese Han population. rs10118757 was genotyped in 1007 CAD patients (including 338 MI patients) and 885 healthy controls. Allelic analysis showed that allele A of rs10118757 was associated with increased risk of CAD, with OR (95%CI)=1.193 (1.035-1.376), and P=0.015. After adjusted for age, BMI, gender, hypertension and smoking, rs10118757 was still significantly associated with CAD under additive and dominant models, with OR (95%CI)=1.252 (1.070-1.465), P=0.005, and OR (95%CI)=1.698 (1.168-2.467), P=0.006, respectively. Compared to additive model, dominant model may be the best-fitting model (P=6.63E-10 vs P=6.70E-10). As reported previously, rs10118757 was not associated with MI in the current study. Our study firstly reported that SNP rs10118757 was associated with CAD risk in a Chinese Han population, indicating that MTAP gene may play a potential role in the pathophysiological process of CAD."
