Area of Science:
- Biochemistry
- Proteomics
- Endocrinology
Background:
- Thyroid fine needle aspiration (FNA) is a common diagnostic procedure.
- Understanding the protein composition of FNA fluid is crucial for diagnosing thyroid conditions.
- Previous proteomic analyses of thyroid FNA fluid are limited.
Purpose of the Study:
- To characterize the protein pattern of human thyroid FNA fluid.
- To establish a proteomic fingerprint for thyroid FNA.
- To identify potential protein markers for thyroid diseases.
Main Methods:
- Proteomic analysis of thyroid FNA fluid.
- Separation of proteins using 2-dimensional gel electrophoresis (2DE).
- Identification of proteins via peptide mass fingerprinting.
Main Results:
- Successfully generated an image of thyroid FNA protein components, identifying approximately 220 protein spots.
- Revealed a specific proteomic fingerprint for thyroid FNA fluid.
- Identified proteins belonging to diverse functional systems.
Conclusions:
- The established protein pattern provides a baseline for thyroid FNA proteome.
- This proteomic fingerprint may serve as a foundation for identifying novel biomarkers for thyroid diseases.

Abstract:
The aim of this study was to determine the protein pattern of human thyroid fine needle aspiration fluid (FNA) using a proteomic approach. FNA proteins were separated using 2-dimensional gel electrophoresis (2DE), digested and then analyzed by peptide mass fingerprinting. For the first time, we provided an image of the protein components of the FNA, in which approximately 220 protein spots can be identified. The proteome analysis revealed a specific fingerprint of FNA with proteins appertaining to various functional systems. Our preliminary results of FNA protein pattern could be a starting point in studying the presence of potential markers implicated in thyroid diseases.
