Abstract
Objective
Polyethylene terephthalate (PET) has emerged as a focal point in addressing global pollution and a critical environmental issue due to its potential health hazards. However, its role in the pathogenesis of osteosarcoma (OS) and the underlying molecular mechanisms remain largely unexplored, further highlighting the necessity of assessing its molecular toxicity.
Methods
This study integrated network toxicology, machine learning, molecular docking, and CIBERSORT-based immune infiltration analysis to systematically investigate the potential impact of PET exposure on contracting OS, elucidating its biological functions, signaling mechanisms, and immune microenvironment. Molecular docking was further applied to characterize the binding properties of PET with hub proteins, and potential therapeutic agents for OS were predicted.
Results
We identified 12 potential key targets of OS associated with PET exposure and, through machine learning models, selected six hub genes (i.e., BCAT1, CDK4, CSF1R, CXCR4, MYB, and PRTN3). Gene Ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) analyses were conducted to elucidate the roles of these genes in biological processes, cellular components, molecular functions, and signaling pathways. Molecular docking results revealed that PET exhibits high specificity in binding to these hub genes, particularly by interacting with CSF1R (−8.312 kcal/mol), potentially activating the PI3K-Akt signaling pathway and modulating the OS immune microenvironment to promote tumor progression through multiple mechanisms. Furthermore, drug prediction analysis identified p-Benzoquinone and JNK-9L as potential therapeutic candidates for OS.
Conclusion
This study reveals that PET may play a critical role in OS development by regulating hub genes and signaling pathways. Molecular docking analysis demonstrates that PET can tightly bind to specific target proteins, suggesting a potential molecular mechanism underlying OS progression. These findings provide a scientific basis for further evaluating PET-related health risks and offer theoretical support for the development of future prevention and treatment strategies.
期刊介绍:
The Journal of Bone Oncology is a peer-reviewed international journal aimed at presenting basic, translational and clinical high-quality research related to bone and cancer.
As the first journal dedicated to cancer induced bone diseases, JBO welcomes original research articles, review articles, editorials and opinion pieces. Case reports will only be considered in exceptional circumstances and only when accompanied by a comprehensive review of the subject.
The areas covered by the journal include:
Bone metastases (pathophysiology, epidemiology, diagnostics, clinical features, prevention, treatment)
Preclinical models of metastasis
Bone microenvironment in cancer (stem cell, bone cell and cancer interactions)
Bone targeted therapy (pharmacology, therapeutic targets, drug development, clinical trials, side-effects, outcome research, health economics)
Cancer treatment induced bone loss (epidemiology, pathophysiology, prevention and management)
Bone imaging (clinical and animal, skeletal interventional radiology)
Bone biomarkers (clinical and translational applications)
Radiotherapy and radio-isotopes
Skeletal complications
Bone pain (mechanisms and management)
Orthopaedic cancer surgery
Primary bone tumours
Clinical guidelines
Multidisciplinary care
