Figure 4. Effect of various (CUG)7 AON concentrations on HTT mRNA expression.

Figure 4

Cells were transfected with 1ā€“20 nM (CUG)7. PCR products with primers flanking the CAG repeat of HTT were quantified by Lab on a Chip. (a) In the control cell line (FLB73) both alleles (17 and 21 CAGs) show a comparable concentration dependent reduction of HTT mRNA quantification after (CUG)7 transfection. (b) In HD fibroblasts (GM04022) the mutant transcript, with 44 CAGs, shows a strong reduction of mutant HTT mRNA expression with increasing (CUG)7 AON concentrations, whereas the normal HTT transcript with 18 CAGs is reduced to a lesser degree. Expression levels are corrected for loading differences with ACTB and mRNA levels of the Mock I transfections were set on 100% (* P<0.05, ** P<0.01, nā€Š=ā€Š4).
