Chemically modified oligomers as huntingtin inhibitors. (A) The sequences of oligomers with indicated chemical modifications at particular positions. (B) The western blot analysis of huntingtin levels in the HD fibroblasts (GM04281) at 72 h after transfection with the indicated oligomers. (C) Representative results for the experiment described in (B) for allele-selective oligomers: PNA and morpholino. C - the reference bar indicates the HTT expression level in the cells transfected with control siRNA. In the graph, the signal intensities were normalized to the plectin protein level and compared using a one-sample t-test. The error bars represent standard deviations. The P-value is indicated by asterisks (* p < 0.001; ** 0.001 < p < 0.05).
