Autophagy, a dynamic and highly conserved cellular process, is notably upregulated in cells under diverse stress conditions. Researchers investigated the role of death-associated protein 1 (DAP1) in modulating autophagy in Graves' disease (GD)-induced osteoporosis (OP) using the RFP Reporter Cell Line-MC3T3. Bone proteomics analysis identified DAP1 as a key protein. Genetic manipulation of DAP1 in MC3T3-E1 cells revealed its effects on autophagy and osteogenic markers. Electron microscopy and MAP1LC3/LC3 fluorescence were used to visualize autophagic vacuoles. Results showed that DAP1 overexpression inhibited autophagy and osteogenesis markers, while knockdown reversed these effects. In vivo, DAP1 knockdown increased bone mass in GD mice. DAP1 was found to regulate autophagy and osteogenesis via the ATG16L1–LC3 axis in osteoblasts, highlighting its role in GD-induced osteoporosis.
Figure 1. The impact of DAP1 on autophagic vacuoles and flux in MC3T3-E1 cells was investigated. RFP Reporter Cell Line-MC3T3 was utilized for fluorescence imaging of autophagic vacuoles. Alterations in autophagic vacuole numbers and distribution were observed, providing insights into DAP1's role in autophagy regulation. These findings contribute to understanding cellular mechanisms underlying bone metabolism. (Gao M, et al., 2023)
