ABSTRACTIntroductionTransforming growth factor-β (TGF-β) is an important cytokine with modulatory actions in the nervous system. The development of hydrocephalus in mouse models resulting from the overexpression of TGF-β1 has previously been described, but the mechanism by which this occurs remains obscure.Methods In order to evaluate the role of TGF-β in hydrocephalus, we used SYBR Green I-based real-time quantitative RT-PCR method and Western blot analysis to analyze the TGF-β2 and TGF-β3 mRNA and protein expressions in the cerebral cortex of the H-Tx rat, a model of congenital hydrocephalus.Results The hydrocephalic H-Tx rat expressed significantly higher TGF-β3 levels than their normal siblings (p<0.01) at 7 and 14 days of age. This difference became insignificant when analyzed at 21 days of age. On the other hand, such a difference has not been observed in the TGF-β2 levels in the hydrocephalic H-Tx rat.Conclusions These results suggest that TGF-β2 and TGF-β3 expression may be modulated differently in the hydrocephalus, and TGF-β3 may contribute to the development of hydrocephalus in this rat model.
