Abstract:
Molecular and functional mechanisms of bone metastases were poorly understood. This study was to screen out differentially expressed genes (DEGs) and functional proteins in bone metastases from lung for better understanding of the molecular and functional mechanisms. Our results suggested CTSS, CTSD, MX1, NKX2-1 might play a decisive role in bone metastasis. Collectively, these results demonstrated that bone metastasis from lung cancer would lead to changes in lysosome function, which may affect the decomposition and elimination of old bone matrix, thus affecting bone turnover. In addition, our findings provided new insights into the prediction and treatment of bone metastases.
Insights
This study identified key genes like CTSS and CTSD involved in lung cancer bone metastasis. These findings reveal altered lysosome function impacting bone turnover and offer new treatment insights.
Area of Science:

Purpose of the Study:
- To screen for differentially expressed genes (DEGs) and functional proteins in lung cancer bone metastases.
- To elucidate the molecular mechanisms driving bone metastasis.
- To identify potential targets for predicting and treating bone metastases.
Main Methods:
- Differential gene expression analysis was performed on bone metastasis samples from lung cancer patients.
- Proteomic analysis was utilized to identify key functional proteins.
- Bioinformatic tools were employed to analyze gene and protein expression data.
Main Results:
- Several differentially expressed genes (DEGs), including CTSS, CTSD, MX1, and NKX2-1, were identified.
- These genes and proteins are suggested to play a critical role in the process of bone metastasis.
- Bone metastasis was associated with significant alterations in lysosome function.
Conclusions:
