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:"Fractalkine/CX3CR1 pathway is considered a major modulator of atherosclerosis. In the present study, expression of CX3CR1 on PBMCs/monocytes of healthy individuals and coronary artery diseased patients was initially assessed by flow cytometry. Effects of pre-inflammatory cytokines interferon (INF)-gamma and tumor necrosis factor (TNF)-alpha on expression of CX3CR1 and a single representative of each major chemokine family (CCR5 and CXCR4) were further assessed in three cell models: THP-1 monocytes, Jurkat T lymphocytes and primary monocytes isolated from healthy donors. Finally, effects of angiotensin-converting enzyme (ACE) inhibitors captopril, lisinopril and angiotensin receptor blocker (ARB) losartan on chemokine receptor expression were evaluated in the same cell models either in a naive or stimulated state. INF-gamma significantly affected the chemokine receptor phenotype of THP-1 cells by increasing the rate of CX3CR1-positive cells. Pre-treatment with the ACE inhibitors, captopril and lisinopril, and the ARB, losartan, did not influence these effects. Captopril and lisinopril similarly had no effect on either stimulated or naive primary monocytes. Yet, a small but repeatable increase in CX3CR1 expression after treatment with losartan was noted. Nevertheless, the latter observation did not retain statistical significance after applying the Bonferroni correction. In conclusion, our data did not indicate any significant effect of the ACE inhibitors on the chemokine receptor phenotype of monocytes."
