Figure Lengend Snippet: ( a ) Indirect IFs demonstrating increased overlapping (yellow/orange) immunoreactivity for TrkA (green) and MitoTracker-labeled mitochondria (red) (upper panels) and Y490 phosphorylated TrkAIII (pTrkAIII, green) and MitoTracker-labeled mitochondria (red) (lower panels) in DTT-treated (5 mM for 6 h) TrkAIII SH-SY5Y cells compared to untreated controls (control). DAPI stained nuclei are blue. (bar = 50 μm). ( b ) Western blots demonstrating TrkAIII cleavage and Y674/5 phosphorylation in mitochondria (50 mg) from DTT-treated (5 mM for 6 h) TrkAIII SH-SY5Y cells compared to untreated TrkAIII SH-SY5Y controls. ( c ) Western blots demonstrating increased PTPase oxidation (arrows) in mitochondria (50 mg) from DTT-treated TrkAIII SH-SY5Y cells (5 mM for 6 h) compared to untreated controls (Con). ( d ) Phase contrast images merged with green fluorescence and histogram demonstrating significant differences (* p < 0.0001) in pcDNA-SH-SY5Y and TrkAIII SH-SY5Y percentage cell death at 24 h and 48 h, induced by 5 mM DTT.
