Abstract: BACKGROUND:  Autophagy is a highly conserved lysosome degradation pathway in eukaryotic cells, which is mainly used to degrade intracellular long-lived proteins, damaged organelles, invasive pathogenic microorganisms, and so on. Recent studies have shown that cell autophagy plays an important role in the occurrence and development of pulmonary hypertension, so elucidating the molecular mechanism of cell autophagy is particularly important for the treatment of pulmonary hypertension.
OBJECTIVE: To generalize the process of autophagy and the regulation of cell signaling pathways on autophagy, to summarize the effect of autophagy in pulmonary hypertension, and to put forward methods to study cell autophagy.
METHODS: With the search formula “Cell Autophagy and Cell Signaling Pathway”, CNKI, WanFang, and VIP were retrieved, and with the search formula “(“ Autophagy “[Mesh]) AND” Signal Transduction “[Mesh]” and “(“Hypertension, Pulmonary”[Mesh]) AND “Autophagy”[Mesh],’’ PubMed was searched. After preliminary screening of the title and abstract to exclude stale and poor-quality literature, a total of 44 literatures were included for analysis.
RESULTS AND CONCLUSION: In recent years, studies have found that autophagy is related to many diseases, and it is unknown about whether autophagy has protective or harmful effects. Many signaling pathways have participated in and regulated autophagy. This paper clarifies the effect of cell signaling pathways on autophagy; explores the relationship between cell signaling pathway proteins and the upstream and downstream of cell autophagy proteins; elucidates the influence of a substance on cell autophagy and signaling pathway, and  the substance maybe regulates cell autophagy via a certain pathway. 

Key words: autophagy, process of autophagy, PI3K/AKT/mTOR signaling pathway, JNK signaling pathway, P38MAPK signaling pathway, ERK signaling pathway, NF-κB signaling pathway, pulmonary hypertension
