Abstract :
Objectives: To compare the plasma protein profiles of treated and untreated congenital hypothyroidism (CH) patients with those of normal control infants. Design and methods: Plasma samples were subjected to two-dimensional gel electrophoresis and silver staining or lectin detection. Resolved protein spots were analyzed by using computerized densitometry software. Results: The significant enhanced expression of the fibrinogen γ-chain and reduced expression of haptoglobin β-chain were demonstrated in the profiles of untreated CH patients using both silver staining and lectin detection methods. Lectin detection resolved only a single cluster of the haptoglobin β-chain for the untreated patients, in contrast to five isoform clusters detected in the controlsʹ and treated CH patientsʹ profiles. Conclusions: Plasma from untreated CH patients demonstrated different altered expression of fibrinogen and haptoglobin polypeptide chains, which was normalized when patients were treated. Our data also suggest differences in structures of the N-glycans of haptoglobin β-chain of the untreated CH patients.
