For isolation of voltage-gated sodium currents ( Figure?2H), internal KCl was replaced by CsCl to block potassium currents and 100?��M CdCl2 was used to block calcium currents. Dissociated neurons (20,000) were plated on poly-D-lysine/laminin coated 8-well chamber slides (BD Biosciences) containing a confluent monolayer of primary cortical mouse glia (Boulting et?al., 2011). For survival analysis, slides were fixed at 3 and 30?days, and cultures were stained for counting. The number of ISL-positive, TUJ1-positive motor neurons (counter [http://www.selleckchem.com/products/Erlotinib-Hydrochloride.html Erlotinib nmr] blinded to cell line identity) was normalized to the number on day 3 for each line. Retigabine (1?��M) or vehicle control was added from day 15 onward. Eleven total experiments (control motor neurons) and nine total experiments (ALS motor neurons) were performed from the same four separate differentiations. ER stress experiments were performed as described in Kiskinis et?al. (2014). In brief, in two separate independent biological replicates, 300?ng of RNA was used to generate cDNA, of which 2?��l and AmpliTaq Gold Polymerase (Applied Biosystems) were used for [http://en.wikipedia.org/wiki/Vasopressin_receptor Vasopressin Receptor] PCR amplification. The amounts of spliced and unspliced bands were quantified using Image J. Quantitative RT-PCR was performed in triplicate using the iSCRIPT kit (Bio-Rad) for cDNA synthesis and SYBR green (Bio-Rad) labeling followed by amplification using the iCycler system (Bio-Rad). Drugs included retigabine (Santa Cruz Biotechnology), bicuculline, strychnine, D-AP5, CNQX, flupirtine, TTX (all from Tocris Bioscience). CsCl and CdCl2 were from Sigma. p?[http://www.selleckchem.com/products/gsk126.html Selleck GSK126] considered statistically significant. Comparisons were made between control and ALS populations using t tests (two-tailed, unpaired)/ANOVA for continuous data and rank tests for nonparametric data (discrete measurements of number of spikes on ramps and rheobase). For analysis of MEA firing over time (Figure?1F), we used a mixed repeated-measures ANOVA model with fixed effects of cell line and time and random effects of individual replicate. For effect of retigabine on specific cells (Figures 3A and 3B), paired tests were used. For effect of retigabine on survival (Figure?3D), we fitted a linear regression model with effects of retigabine treatment, cell line, and their interaction. F-tests for difference between ALS and control lines gave p?= 0.0011, for effect of retigabine p?= 3.8?�� 10?4, and for effect modification p?= 0.015. For ALS subjects, the effect of retigabine was an increase in cell count of 25.3% (SD 5.6, p?= 6.4?�� 10?5). The effect estimate for 39b was 16.9% (SD 12.9, p?= 0.03) and for RB9d 39.9% (SD 11.3, p?= 0.001). For control subjects, the effect of retigabine was an increase in cell count of 6.1% (SD 5.1, p?= 0.23). For multiple genotype comparisons (Figure?5A), one-way ANOVA after log transformation to normalize variance and post hoc Tukey tests were used to analyze multiple ALS variants.
