The distribution of acidic (aFGF) and basic (bFGF) fibroblast growth factor mRNA and protein were examined in mesencephalon by immunohistochemistry, immunoblot analysis, in situ hybridization histochemistry, and RNA analysis. Coexistence of aFGF or bFGF with tyrosine hydroxylase protein in nigral cells was observed with immunohistochemistry. Both aFGF and bFGF mRNAs were found in the substantia nigra. Unilateral 6-hydroxydopamine lesions of nigrostriatal neurons resulted in a loss of aFGF and tyrosine hydroxylase [L-tyrosine, tetrahydropteridine: oxygen oxidoreductase (3-hydroxylating), EC 22.214.171.124] mRNA-positive neurons on the lesioned side. The distribution of aFGF mRNA in monkey brain was similar to that seen in the rat. RNA and immunoblot analysis confirmed the presence of both aFGF and bFGF mRNAs and proteins in the substantia nigra of rat, monkey, and human.
