The design of HCCDB

MongoDB was used to store the data of archived HCC datasets, GTEx, and TCGA in the format of JSON. Echarts was applied for charting and data visualization. HCCDB provides four main pages and serval downstream pages. The possible jumps among HCCDB pages and the third-party links are indicated by arrows. HCC, hepatocellular carcinoma; GTEx, Genotype-Tissue Expression; TCGA, The Cancer Genome Atlas; HPA, Human Protein Atlas; TTD, Therapeutic Target Database; GEO, Gene Expression Omnibus; Up-list, up-regulated gene list; Down-list, down-regulated gene list; Co-genes, co-expressed genes.
