Gangliotetraose (Gg4) is a tetrasccharide, exhibits major components including GM1 and its sialylated derivatives. GM1 facilitates efflux of nuclear Ca2+ and reduces the level of nuclear Ca2+ that characterizes the differentiated neuron. GM1 affects neuronal plasticity and repair mechanisms, as well as neurotrophin release in the brain[1][2]. | [in vivo]
Gangliotetraose (GM1) (30 mg/kg; i.p.; 5, 11, 42, and 73 d) stimulates the regeneration of nigrostriatal dopaminergic neurons in the central nervous system of rats after unilateral hemitransection[5].
| Animal Model: | Unilateral semi-transection model in Sprague-Dawley rats (170-190 g)[5] | | Dosage: | 5 mg/kg; 30 mg/kg | | Administration: | Intraperitoneal injection; 5, 11, 42, 73 days; started on day 2 after surgery and finished 24 h before sacrifice | | Result: | Increased the Vmax of tyrosine hydroxylase (TH) in the lesioned side starting on day 14 dose-dependently with 73% (5 mg/kg/d) and 85% (30 mg/kg/d) of that of the unlesioned side, respectively. |
