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:"TBX1, encoding a T-box containing transcription factor, is the major candidate gene for del22q11.2 or DiGeorge syndrome, characterized by craniofacial and cardiovascular defects including tetralogy of Fallot and common arterial trunk. Mice lacking Tbx1 have severe defects in the development of pharyngeal derivatives including cardiac progenitor cells of the second heart field that contribute to the arterial pole of the heart. The outflow tract of Tbx1 mutant embryos is short and narrow resulting in common arterial trunk. Here we show by a series of genetic crosses using transgene markers of second heart field derived myocardium and coronary endothelial cells that a subdomain of myocardium normally observed at the base of the pulmonary trunk is reduced and malpositioned in Tbx1 mutant hearts. This defect is associated with anomalous coronary artery patterning. Both right and left coronary ostia form predominantly at the right/ventral sinus in mutant hearts, proximal coronary arteries coursing across the normally coronary free ventral region of the heart. We have identified Semaphorin3c as a Tbx1-dependent gene expressed in subpulmonary myocardium. Our results implicate second heart field development in coronary artery patterning and provide new insights into the association between conotruncal defects and coronary artery anomalies."
