11679167AKTAkt0.0is an homologue of the mammalian protein kinase B/Akt, B Akt which is involved in insulin signalling apoptosis and cellular proliferation 
11679167AKTAkt0.0Sch9/Rim15 Sch9 Rim15 and the C elegans DAF-2/AGE-1/Akt/DAF16 DAF-2 AGE-1 Akt DAF16 pathways play similar roles in regulating ageing and stress

12654515AKTAkt0.3neuron-like cell death from mutant G93A-SOD1 effects via PI3-K/Akt PI3-K Akt activation 
12654515AKTAkt0.0In addition we show that Akt activation promotes NSC34 motor neuron-like cell survival in the presence 
12654515AKTAkt0.3cell survival is mediated by activation of the PI3-K/Akt PI3-K Akt pathway 2

12654515AKTAkt0.1One of the downstream effectors of PI3-K is Akt activation 
12654515AKTAkt0.0examined whether VEGF treatment of NSC34 cells was associated with Akt phosphorylation 
12654515AKTAkt0.0Indeed cells exposed to VEGF displayed concentration- and time-dependent Akt activation ( Fig 5D and E 
12654515AKTAkt0.0Overexpression of the dominant negative mutant of Akt resulted in a significant reduction in the protective effect by 
12654515AKTAkt0.0In contrast expression of constitutively active Akt increased cell survival despite the presence of mutant G93A-SOD1 ( 
12654515AKTAkt0.1Taken together the data indicate that activation of Akt by VEGF contributes to the protection from NSC34 motor neuron-like 
12654515AKTAkt0.3Thus it is possible that the PI3-K/Akt PI3-K Akt signaling module recruited by VEGF in our experiments is associated 
12654515AKTAkt0.0Our experiments further revealed that Akt activation is essential for implementation of the protective effect by 
12654515AKTAkt0.0Indeed expression of dominant negative Akt blocked the protective function of VEGF while the expression of 
12654515AKTAkt0.0protective function of VEGF while the expression of constitutively active Akt partially prevented mutant SOD1-mediated motor neuron-like cell death even in 
12654515AKTAkt0.0These findings are not surprising since Akt is now well established as a critical protein activated by 
12654515AKTAkt0.0Once phosphorylated Akt has been demonstrated to promote cell survival by inactivation of 
12654515AKTAkt0.3However several lines of evidence suggest that the VEGF/Akt VEGF Akt pathway is particularly important to neuronal survival 
12654515AKTAkt0.1a pre-conditioning hypoxic stimulus up-regulated the expression of VEGF and Akt and the activity of the latter was critical to increased 
12654515AKTAkt0.0Similarly expression of active Akt suppressed mouse hippocampal neuronal death induced by hypoxia glutamate or 
12654515AKTAkt0.0In addition activation of Akt was tightly linked to neuronal cell survival after traumatic brain 
12654515AKTAkt0.3We now demonstrate that the activation of PI3-K/Akt PI3-K Akt signaling pathways by VEGF can promote motor neuron-like cell survival 
12654515AKTAkt0.3However since the activation of PI3-K/Akt PI3-K Akt is a transient event ( Fig 4 the long-lasting protective 
12654515AKTAkt0.3and molecular genetic approaches we have demonstrated that PI3-K/Akt PI3-K Akt activation is the primary contributor to the neuroprotective function of
