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:"OBJECTIVE: HIV-infected individuals are at increased risk for myocardial infarction. Given observations that cytomegalovirus (CMV) infection, CMV-specific T cells, and CX3CR1 have each been associated with atherosclerosis, we hypothesized that CMV-induced T-cell immunopathology could contribute to HIV-associated atherosclerosis. METHODS: We measured the expression of CX3CR1 on peripheral blood mononuclear cells and its association with carotid artery intima-media thickness (IMT) in 29 HIV-infected individuals and 48 uninfected controls. We analyzed the phenotype and specificity of CX3CR1(+)CD4(+) T cells, the production of CX3CL1 (the ligand of CX3CR1) by CMV-infected endothelial cells in vitro, and the migration of CD4(+) T cells induced by CX3CL1. RESULTS: The progression of atherosclerosis in HIV-infected individuals, as assessed by longitudinal measurements of carotid IMT, was associated with a high frequency of CD4(+) T cells that express the chemokine receptor CX3CR1. Such CD4(+)CX3CR1(+) T cells were antigen-primed, produced high levels of pro-inflammatory cytokines, and composed the majority of the CMV-specific CD4(+) T cells. CMV-stimulated CD4(+) T cells were also found to induce the production of CX3CL1 (the ligand for CX3CR1) by human arterial endothelial cells, driving the transendothelial migration of pro-inflammatory CD4(+) T cells. Finally, we observed that CD4(+)CX3CR1(+) T cells could be localized to the coronary arterial wall in HIV disease. CONCLUSION: HIV-associated atherosclerosis may be driven by a positive feedback pathway in which a high frequency of antigen-stimulated, CMV-specific CD4(+)CX3CR1(+) T cells induce endothelial cells to secrete CX3CL1, which itself drives progressive infiltration of the arterial wall by pro-inflammatory cells."
