Network Analysis of 20S-Ginsenoside Rg3 Effect on Human Colorectal Adenocarcinoma Cell Line HT-29

Abstract

Background and objectives: 20S-Ginsenoside Rg3 is a pharmacological active compound of ginseng. Evidences indicate that S20-Rg3 as an anti-cancer factor plays role in prevention and treatment of cancer. In the present study, proteomic data of 20S-ginsenoside Rg3 effect on human colorectal adenocarcinoma cell line HT-29 was analyzed via network analysis to understand more details about the molecular events. Methods: The differentially expressed proteins (DEPs) related to the effect of 20S-ginsenoside Rg3 on human colorectal adenocarcinoma cell line HT-29 were extracted from literature and analyzed via protein-protein interaction (PPI) network. The central nodes of the network were determined based on degree value and betweenness centrality. Results: Eight DEPS plus 100 added first neighbors were included in the PPI network. Five central nodes as hub-bottlenecks including ACTB, GAPDH, TP53, AKT1, and ALB among the added first neighbors and ANXA5 as hub-bottleneck and GSTP1 and PCNA as bottlenecks among the queried DEPs were introduced. Conclusion: PCNA, GSTP1, and ANxA5 as cell protective proteins are the crucial targeted proteins by 20S-ginsenoside Rg3 in the treated cell line HT-29. Up-regulation of GSTP1 and ANXA5 is correspondent to the cell protective property of 20S-ginsenoside Rg3, and down-regulation of PCNA refers to the opposite effect. It seems that cell protective roles of 20S-ginsenoside Rg3 are accompanied with the possible side effects.
