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:"BACKGROUND: Serotonin is a platelet agonist and potent vasoconstrictor that has recently received attention concerning its potential role in acute coronary artery thrombosis. Selective serotonin-reuptake inhibitors, such as paroxetine, are widely used antidepressant agents. We sought to characterize the potential inhibitory effect of paroxetine on platelet function. METHODS: Healthy male volunteers received 20 mg/d paroxetine for 2 weeks in a randomized, double-blind, placebo-controlled, two-way cross-over trial. RESULTS: Paroxetine decreased intraplatelet serotonin concentrations by -83% (P < .01). This inhibited platelet plug formation as reflected by a 31% prolongation of closure time measured with the platelet function analyzer-100 (P < .05). Furthermore, paroxetine lowered expression of the platelet activation marker CD63 in response to two different concentrations of thrombin receptor-activating peptide (P < .01). Plasma concentrations of prothrombin fragment, von Willebrand factor antigen, and circulating P-selectin remained unchanged in either period, indicating that paroxetine does not increase activation of coagulation, endothelium, or platelets in vivo, underlining a favorable safety profile. CONCLUSIONS: Paroxetine substantially decreases intraplatelet serotonin content and thereby reduces platelet plug formation under shear stress, and responsiveness to thrombin receptor activating peptide-induced platelet activation. Further studies will reveal whether these pharmacodynamic effects can be exploited for treatment of thrombotic artery disease."
