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.

    Basic Information

    Gene Name: CTSS

    Description: cathepsin S

    Entrez Gene ID: 1520

    SwissProt Acc Number: P25774

    RefSeq: NM_004079

    It was suspected to be CHD related:

    ..Recent data suggested the participation of lysosomal cysteine proteases such as cathepsin S (CTSS) in atherogenesis.The CTSS -25G/A polymorphism was not related with CHD in our Chinese population sample...

    From PMID: 19593952, in Journal Acta Cardiol.? , 2009


    There were 0 potential papers with CTSS and CHD.

    NOTEs: These result is mostly from TEXT-MINING and there might have mismatches.
