Experimental details: Immunocytochemistry analysis of DNM1L in HeLa cells fixed for 10 minutes using 10% formalin and then permeabilized for 5 minutes using 1X TBS + 0.5% Triton X-100. Samples were incubated in DNM1L polyclonal antibody (Product # PA1-16987) using a dilution of 5 µg/mL overnight at 4 °C followed by anti-rabbit DyLight 488 (Green) with a dilution of 1:500. Alpha tubulin (DM1A) was used as a co-stain at 1:1000 and detected with an anti-mouse DyLight 550 (Red) at 1:500. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 40X objective.

Experimental details: Fig. 1 The effects of l -NAME on SNO-PDI, SNO-DRP1, and mitochondrial fusion in CA1 neurons under normal condition. l -NAME inhibits NO generation and the binding of PDI to DRP1, and reduces SNO-PDI and SNO-DRP1 levels without changed PDI and DRP1 expressions. However, l -NAME elongates mitochondrial length in CA1 neurons, accompanied by elevated DRP1-S616 phosphorylation. a Quantitative values (mean +- S.E.M) of nitrate/nitrite levels in the hippocampus 7 days after l -NAME infusion.

Experimental details: Fig. 4 The effects of l -NAME on SNO-PDI, SNO-DRP1, Trx1 activity, and mitochondrial fusion in CA1 neurons 3 days after SE. SE significantly reduces expression levels of DRP1 and PDI, PDI-binding to DRP1, and phosphorylation levels of DRP1-S616 and S637 levels independent of Trx1 activity. Both SNO-PDI and SNO-DRP1 are more diminished by l -NAME treatment. a Representative western blot for the effect of l -NAME on expression, S -nitrosylation, and phosphorylation levels of PDI and DRP1 following SE. b - d Quantification of values (mean +- S.E.M) of expression, phosphorylation, and S -nitrosylation levels of PDI and DRP1.
