qRT-PCR of SMN and SNCA in human SMA fibroblasts and NSC-34 cell clones. a qRT-PCR of SMN and SNCA in human SMA fibroblasts. Fibroblasts derived from an SMA type I and type III patient were compared to control. SMN1 (left) showed a decreased expression from control to type III to type I, respectively. SNCA mRNA level (right) showed a similar deceasing profile across samples from the same patients. Regression analysis using the RT-PCR cycle counts indicated a significant proportion of the variance in SNCA can be explained by knowing the SMN1 level (R2 = 0.49 (F(1,7) = 8.8049, p < 0.02). b qRT-PCR of Smn and Snca in NSC-34 cell clones. NSC-34 cell clones with differing SMN expression level, including that used in Table 1, were examined at passage 7. The C-6 cells Smn expression was 20% lower than control, while Snca expression was 48% lower. Smn expression in the more severe C-2 cells was lowered by 85% compared to control, while Snca expression was 98% lower. All measurements in this figure represent averaged triplicates
