LMNA and Huntington disease: Conversely, in HD neurons, this combination did induce cell death where either insult alone did not (Figure 5D, treatment p < 0.0001, genotype p < 0.0001, post-test vs. nGFP same genotype Hu18/18 progerin p = 0.1679, H2O2p > 0.9999, progerin + H2O2p = 0.3909; Hu97/18 progerin p = 0.3781, H2O2p > 0.9999, progerin + H2O2p < 0.0001).
