|a OBJECTIVE: To screen differentially expressed brain proteins with proteomic method in cerebral cortex of neonatal rats with congenital hypothyroidism
|
| 520 |
|
|
|a METHOD: From the 13th day of gestation, pregnant Wistar rats from the experimental group were given intragastrically with 2.5 ml of 1% propylthiouracil daily. Cerebral cortex specimens were collected from the control and hypothyroidism neonatal rats. Two-directional electrophoresis (2-DE) was applied to analyze protein expression diversities between the euthyroid and hypothyroidism neonatal rat cerebral cortex. Protein spots with significantly different expression were screened and identified by mass spectrometry. Radioimmunoassay (RIA) was used to analyze serum FT(3), FT(4) levels of each groups

|
|a RESULT: The body weight of hypothyroid neonatal rats were lower than those in the corresponding control group (t = -8.07, P < 0.01). The FT(3) levels of hypothyroid neonatal rats were lower than those in the corresponding control group (t = 5.39, P < 0.01). The FT(4) levels of hypothyroid neonatal rats were lower than those in the corresponding control group (t = 7.62, P < 0.01). Stable 2-DE maps of normal and CH neonatal rat were constantly obtained. The maps were analyzed by software. Seven protein spots with high reproducibility, high resolution and significantly different expression were chosen and identified by mass spectrometry, including collapsing response mediator protein 2, actin related protein 2/3 complex subunit 5, ubiquitin-conjugating enzyme E2-25K, ATP synthase subunit d, Cu-Zn superoxide dismutase, synuclein alpha, and nucleoside diphosphate kinase

|a CONCLUSION: The value of this research is demonstrated here by the identification of several proteins known to be associated with nerve synapse structures formation, cell survival, metabolism, cell signal transduction, neural differentiation and nerve growth in the central nervous system. Furthermore this study identified several proteins except for collapsing response mediator protein 2 and Cu-Zn superoxide dismutase that have not previously been described in the literature and which may play an important role as either sensitive biomarkers of brain dysfunction caused by congenital hypothyroidism. In congenital hypothyroidism, brain development retardation may be related with some important processes, including abnormal synaptic formation, excess ROS production and apoptosis. The above-mentioned proteins may play critical roles in the processes, which provide valuable clues to clarify the pathogenesis of brain developmental disorders induced by congenital hypothyroidism
