Identifying significant crosstalk of pathways in tuberous sclerosis complex.

OBJECTIVE Tuberous sclerosis complex (TSC) is the second most common phakomatosis and is characterized by the formation of benign hamartomas and low-grade neoplasms in multiple organ systems. In this study, our objective here was to explore the interaction and crosstalk between pathways in response to tuberous sclerosis complex. MATERIALS AND METHODS We enriched the significant pathways and made the crosstalk analysis of the significant pathways. RESULTS The results showed that ECM-receptor interaction was a significant pathway in TSC. In addition, insulin-signaling and mTOR signaling also have been identified involved in TSC here, which have been well characterized. Further analysis indicated that there was a crosstalk between ECM-receptor interaction and antigen processing and presentation, ECM-receptor interaction and apoptosis, and leishmaniasis-oxidative phosphorylation-pancreatic cancer. In this study, a network-based approach was used to analyze the crosstalk among TSC related pathways. The crosstalk of pathways is found and analyzed using the PPI datasets and expression profiles. CONCLUSIONS Our work showed that comprehensive and system-wide analysis could provide evidence for TSC pathway and complement the traditional component-based approaches. The crosstalk identified might provide new alternative insights into the TSC pathology, which may contribute to the development of novel therapeutic targets for TSC.
