Pi3k/akt signaling pathway and bone destruction: Problems and mechanisms / 中国组织工程研究

ABSTRACT

BACKGROUND: In recent years, the PI3K/AKT signaling pathway is closely related to bone destruction-related diseases. Inhibitors targeting this signaling pathway are also undergoing extensive research, which provides new ideas for clinical treatment of bone destruction-related diseases. OBJECTIVE: To review the research of PI3K/AKT signaling pathway in bone destruction. METHODS: WanFang and PubMed databases were searched for relevant articles published from January 1998 to August 2019. The retrieval key words were “PI3K/Akt signaling pathway; osteoclasts; osteoblasts; bone destruction” in Chinese and English, respectively. To exclude duplicate studies by reading the title and abstract, finally 67 articles were included in result analysis. RESULTS AND CONCLUSION: An appropriate balance between osteoblast and osteoclast-mediated osteogenesis and bone resorption is necessary to maintain bone homeostasis, and an imbalance between these two biological processes will result in bone destructi on. PI3K/Akt signaling pathway is a signal transduction pathway that regulates cell activities and plays an important role in cell proliferation, apoptosis and differentiation. The PI3K/Akt signaling pathway is involved in the inhibition of osteoporosis by promoting osteoblast proliferation, differentiation and bone formation. These results reveal that further exploration on the inhibitors of the PI3K/Akt signaling pathway related to bone destruction will provide new ideas for drug therapy in clinical practice.
