categories that are closest to the “hallmarks of cancer” were defined as either closest GO terms or gene sets related to known functions of syndecan-1; all KEGG pathways present in human, including 9 cancer pathways; and gene sets provided as curated gene sets “C2″for gene set enrichment analysis at http://www.broadinstitute.org/ gsea/msigdb/genesets.jsp. To achieve maximal coverage and sensitivity of the analysis, we obtained a network for the enrichment analysis by merging the FunCoup network of functional coupling and known links from the curated databases, which resulted in a union network of 1,484,166 functional links between 16,302 distinct HUPO 
gene symbols. Network enrichment was estimated by using NEA Z-scores. The standard Z-score for the biological network connectivity between genes of a novel list A and genes of a known functional group F was computed from the observed and expected link counts and their n standard deviation: z~ nAFs effect Indirubin blocked RAR-STAT3 crosstalk Complementary action by reducing JAK/STAT3 signaling. Tanshinone IIA reduced RAR by hindering AR. These complement tetraarsenic tetrasulfide’s action on RAR Indirubin inhibited and reduced CDK2 to complement tetraarsenic tetrasulfide’s action on CDK2 Complementary action Down-regulated CDK2 in NB4 and NB4-R2 Cell cycle cells regulation Upregulated RING-type E3 ligase c-CBL and Growth inhibition degraded BCR-ABL Transported into tumor cells by AQP9 RARa reduction downregulated P53 and elevated Bcl-2 to reduce apoptosis Indirubin Inhibited and reduced CDK2 to produce anticancer effect Inhibited GSK3 to produce anticancer effect blocked VEGFR2 signaling to reduce angiogenesis and apoptosis Activated AhR which activates RARa to promote cancer Tanshinone IIA Increased Bax/Bcl-2 ratio, caspase 3, reduced Bcl-2, mitochondrial membrane potential, MMPs, to promote apoptosis Activated p53 signaling to promote anticancer effect Upregulated pP38 to enhance apoptosis Reduced HER2, NF-kBp65, RARa activities to promote anticancer effect, Reduced and antagonized AR and induced apoptosis pP38 upregulation activated RARa to promote cancer Upregulated efflux transporters to promote Tanshinone IIA eflux Scutellarein site Intracellular bioavailability Counteractive action Cell cycle regulation Growth inhibition Growth, angiogenesis inhibition Indirubin and Tanshinone IIA upregulated APQ9 to promote Tetraarsenic tetrasulfide’s cell entry Tanshinone IIA activated p53 signaling to reduce this counteractive action Tetraarsenic tetrasulfide reduced CDK2 to complement indirubin’s action on CDK2 Intracellular bioavailability enhancement Anti-counteractive action Complementary action Counteractive action Tetraarsenic tetrasulfide degraded PML-RAR to alleviate this counteractive action Apoptosis Anti-counteractive action Cell cycle regulation, apoptosis Apoptosis Apoptosis, growth inhibition, Growth inhibition Counteractive action Intracellular bioavailability Tetraarsenic tetrasulfide degraded PML-RAR to alleviate this counteractive action Indirubin inhibit certain efflux pumps which may reduce the efflux of Tanshinone IIA Anti-counteractive action Intracellular bioavailability enhancement The detailed descriptions of the relevant molecular interaction profiles are in efficacies are reportedly reduced by network robustness, redundancy, crosstalk, and compensatory and neutralizing actions. Our revealed potency-enhancing molecular modes provide useful clues for reducing these literature-reported nega
