Query Compound: Users can search the interested compound to access miRSNP, SNP, miRNA, and gene related to the chemotherapy resistance of the queried compound (Figure 3).

Figure 3. Query compound.

Query SNP: In the search result page, the users can know that whether the queried SNP is CRmiRSNP and which chemotherapy resistance of compound is associated with this SNP. Additionally, users can aware that whether the SNP presents in the 3'UTR of the gene transcripts or in miRNA precursor transcripts (Figure 4).

Query MiRNA: In the search result page, the users can know that whether the CRmiRSNPs locate on the queried miRNA and which compounds chemotherapy resistance is associated with this miRNA. Additionally, users can find the information about SNPs that present in this miRNA precursor transcript and target genes of this miRNA (Figure 5).

Query Gene: In the search result page, the users can know that whether the CRmiRSNPs locate on 3'UTR of the queried gene transcripts and which compounds chemotherapy resistance is associated with this gene. Additionally, users can find the information about SNPs that present in 3'UTR of this gene's transcripts and miRNAs that potentially target this gene (Figure 6).
