UTP-induced phosphorylation of Akt and ERK in retinal cultures: inhibition by Src and PI3K inhibitors. Retinal cultures at E8C8 were incubated with 100 μM UTP for 5 min in the absence or presence of 1 μM Src inhibitor-1 or 25 μM LY294002. a Representative blots of three independent experiments performed in duplicate. b, c Blots were quantified by densitometry and expressed as mean ± SEM (arbitrary units). ***p < 0.001, compared to control cultures. ^## p < 0.01 and ^### p < 0.001, compared to UTP-treated cultures
