Fig 1: DeepCLIP predicts increased TDP-43 binding as mechanism behind ACADM exon 6 skipping. (A) DeepCLIP TDP-43 profile across the 5'ss of ACADM exon 6 with wt indicated in black and patient mutation indicated in red. Along the first axis the sequence is shown and along the second axis the DeepCLIP BLSTM values are shown. SPRi oligo location and SSO locations are indicated in blue and red bars above and below the sequence, respectively. (B) Splicing of wt and mutant minigenes with either TDP-43 targeting siRNA or non-targeting siRNA determined by RT-PCR. (C) Western blot of TDP-43 and HPRT from siRNA and minigene transfected samples. (D) Splicing of wt and mutant minigenes treated with either a control SSO (Ctrl-SSO), SSO1, or SSO2 determined by RT-PCR. (E) DeepCLIP profile of short RNA oligos used in SPRi measurement, reference in black and +7A>G variant in red. (F) The difference in DeepCLIP binding profiles in (E) between reference and variant. Positive score indicates higher score in variant. (G) SPRi measurements of TDP-43 binding to the wt oligo in (E). (H) SPRi measurements of TDP-43 binding to the variant oligo in (E). In both (G) and (H), the black line indicates the fitted binding model.
Fig 2: hnRNP A1 and hnRNP A2/B1 regulate inclusion of IKBKAP exon 20. Knockdowns of hnRNP A1 or hnRNP A2/B1 in four different FD patient fibroblasts GMO4663, GMO4589, GMO4899 and GMO2343. (A) hnRNP A1 knockdown increases IKBKAP exon 20 inclusion, while hnRNP A2/B1 decreases IKBKAP exon 20 inclusion. (B) IKBKAP exon 20 inclusion was quantified using the fragment analyzer. Error bars indicates SEM, n = 2 ***P-value < 0.001, **P-value < 0.01, *P-value < 0.05 knockdown was validated by qPCR where expression of hnRNP A1 (C) and hnRNP A2/B1 (D) was normalized to the expression of TBP. Error bars indicates SEM, n = 3 ***P-value < 0.001, **P-value < 0.01, *P-value < 0.05. (E) Knockdown of hnRNP A1 and hnRNP A2/B1 was confirmed by western blotting (GMO4663) and HPRT was used as a loading control.
