Abstract:
Objective To explore the network structure of genes and microRNA(miRNA) at the system level and to study topological characteristics of survival rate related molecules by means of survival analysis.Methods Regulatory networks were established with genes of hepatocellular carcinoma( HCC) and with the expression profiling data of miRNA. Survival knowledge in nodes was studied.Results All the nodes in gene co-expression networks conformed to power-law distribution.In a network, high-degree nodes were called Hub, which enriched more survival related genes than lower degree ones.Conclusion Hub nodes in gene regulatory networks promise to be potential features for molecular subtyping.
