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: PALLD

    Description: "palladin, cytoskeletal associated protein"

    Entrez Gene ID: 23022

    SwissProt Acc Number: Q8WX93

    RefSeq: NM_001166108

    It was supported literatures to be a novel CHD related gene:

    .."A single-nucleotide polymorphism (SNP) in the palladin gene (PALLD, rs7439293) has recently been reported to be associated with coronary heart disease (CHD) in two case-control studies as well as in a large population-based cohort (Atherosclerosis Risk in Communities study, ARIC). "..

    From PMID: 21054356, in Journal Eur J Clin Invest , 2011


    There were 2 potential papers with PALLD and CHD.
