20003314 Falk T, Zhang S, Sherman SJ: Vascular endothelial growth factor B (VEGF-B) is up-regulated and exogenous VEGF-B is neuroprotective in a culture model of Parkinson's disease. Mol Neurodegener. 2009 Dec 10;4:49.

Neurotrophic factors have shown preclinical promise, but the choice of an appropriate growth factor as well as the delivery has proven difficult.
In this study, we used a rotenone rat midbrain culture model to identify genes that are changed after addition of the neurotoxin. (1) We challenged rat midbrain cultures with rotenone (20 nM), a pesticide that has been shown to be toxic for dopaminergic neurons and that has been a well-characterized model of PD.

The survival and functional maintenance of vertebrate neurons depends on the availability of specific neurotrophic factors.
Down-regulation of Ret was also observed in dopamine-producing PC12 cells undergoing apoptosis induced by rotenone, another toxic substance for dopaminergic neurons, while other cellular components were not affected.

METHODS: We evaluated the protective effects of conditioned medium (CM) from cultured RPE cells on the DAergic cells against 6-hydroxydopamine (6-OHDA)- and rotenone-induced neurotoxicity and determined the levels of glial cell derived neurotrophic factor (GDNF) and brain derived neurotrophic factor (BDNF) released by RPE cells.

Moreover, other neurotrophic factors such as brain-derived neurotrophic factor and glia cell line-derived neurotrophic factor also reduced rotenone- or colchicine-induced microtubule depolymerization and death of TH (+) through a MEK-dependent mechanism.

In this paper, we focused on the differences between rotenone and manganese as toxins, and characterized the influence of neurotrophic factors on toxin-induced apoptosis in PC12 cells.
