Secretomes of Gingival Fibroblasts From Periodontally Diseased Tissues: A Proteomic Analysis
Objective
Cell secretomes represent a promising strategy for periodontal and bone regeneration. The objective of this study was to characterize the secretome of human gingival fibroblasts (GF) from periodontally diseased tissues (GF-perio) using proteomics.
Materials and Methods
Conditioned media of GF-perio from periodontitis patients (n = 6, 48-h serum-free culture) were subjected to liquid chromatography with tandem mass spectrometry. Global profiles, differentially expressed proteins (DEPs), and functional/gene-set enrichment (FEA) were analyzed using bioinformatics. Selected bone regeneration-related proteins were additionally measured using a multiplex immunoassay. Conditioned media of GF from periodontally healthy subjects were used as a reference.
Results
Overall, 1833 proteins were detected in GF-perio secretomes, including several growth factors, cytokines, chemokines, and extracellular matrix proteins important for wound healing and regeneration. Key bone-related cytokines (FGF2, MCP1, GPNMB, MMP2, IL6, IL8) were confirmed by an immunoassay. Compared to the reference group, 127 exclusive proteins and 73 DEPs (p < 0.05) were identified in the GF-perio group. FEA revealed significant enrichment of “exosome” and “cytoplasm” related cellular components in GF-perio secretomes.
Conclusion
The secretome of GF from periodontally diseased tissues may hold therapeutic potential, with several proteins important for wound healing and regeneration, especially those related to exosome functions.
期刊介绍：
Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
