AbstractAs a classical form of programmed cell death, autophagy is widely involved in cellular metabolism and vital for the maintenance of homeostasis in physiological and pathological states. With multiple levels of regulation and signaling integrated in, autography presents complicated relevance with various diseases, such as cancer and neurological diseases. The emerging subject, systems biology, along with multi-omics approaches, offers a new strategy to investigate these interactive processes from a holistic perspective. In this chapter, we focus on the systems biology method for autophagy research and introduce essential research skills and procedures. The critical step of systematic study is to explore interplay between biological molecules based on massive biological data, which requires construction of networks in different biological levels, modification, and identification of key pathways and targets via optimized algorithm and experimental verification. Guided by systems biology research, drug design can thus be strengthened by efficient screening and accurate evaluation. Overall, systems biology promises to act as a powerful tool which both helps to clarify the profound mechanism and to develop efficacious medicine.
