Figure 5. Hyperglycaemia-induced post-translational regulation of VEGF.

Figure 5

(A) Exposure to glucose 45 mM for 24 hours increased the level of secreted VEGF in neuron-SC co-cultures and SC monocultures. Data are express as percentage difference between their own control in independent experiments (n = 5) *p<0.05. (B) Hyperglycaemia significantly increased VEGF mRNA only in neuron monocultures (n = 5). (C) Representative and (D) quantitative western blot (WB) demonstrating VEGF decrease in hyperglycaemia-conditioned SC monocultures compared with control SC monocultures. VEGF level was not affected in neuron monocultures. Data are expressed as mean±SEM of independent experiments (n = 4) *p<0.05 vs controls. (E) VEGF induced a significant reduction in axonal outgrowth in neuron/Schwann cells coculture. Data are expressed as mean±SEM of independent experiments (n = 3) *p<0.05 vs controls.
