TRED:http://rulai.cshl.edu/TRED/TFlist.htm能直接下载的是主要的是36 curated cancer-TF families。TF家族的调控网络；GENE数据来自ensembl(hg19)；

    Database Statistics：介绍基因数据来源

    Browse Database：可以根据物种和染色体，搜索：基因，启动子，绑定位点，直系同源；转录因子：点击后会连接到genebank和TRANSFAC.

      search TF Target：可以输入TF，根据绑定启动子质量和绑定质量找寻TF 的靶标

      Gene Regulatory Network：36个与癌症相关家族的TF的网络，点击一个家族，则可以看到每个家族都有一个TF与基因的网络；在这个图中，黑线的含义未知；

"Promoter qualities ranked from high to low: 1, known, curated promoters; 2, known, pipeline collected promoters; 3, predicted promoters with Refseq evidence and putative promoters taking 5′ ends of Refseq as TSSs; 4, predicted promoters with mRNA (other than Refseq and EST) evidence; 5, predicted promoters with EST evidence; 6, predicted promoters supported only by gene prediction.Promoters included in a higher ranking are automatically excluded from the lower ranking categories."

 "A binding quality level was assigned based on definitiveness of the binding evidence, which was determined by the experimental approaches employed to demonstrate the binding and data interpretation from experts. For example, we assigned ‘known’ as the binding quality level to a binding that has been proved by gel-shift competition, DNase I footprinting, etc."
