p53 downregulation rescues neurodevelopmental defects in XLID JMS patient hiPSCs

(A) Relative number of rosettes upon neural differentiation of WT-DYS0100, JMS-cl.1, and JMS-cl.1-expressing shRNA control (shCtrl) or shRNA targeting p53 (shP53a and shP53b) hiPSCs (n ≥ 3, biological replicates). JMS cells harbor HUWE1 p.G4310R.

(B–D) mRNA expression levels of NES/NESTIN (B), TUBB3/TUJ1 (C), and DCX (D) analyzed by qRT-PCR in WT and JMS neural cells (collected at day 13) addressed by qRT-PCR.

(E) Immunofluorescence analysis of the TUJ1 signal in WT-DYS0100, JMS-cl.1, JMS-cl.1 shCtrl, and JMS-cl.1 shP53a and shP53b at day 13 of neural differentiation.

(F–H) qRT-PCR analysis of CDKN1A/p21 (F), GADD45α (G), and BAX (H) expression in WT and JMS neural cells (collected at day 13).

All error bars indicate mean ± SEM (n = 3, biological replicates); one-way ANOVA followed by Dunnett’s post-test (A); one-tailed t test (B–D and F–H); ∗p ≤ 0.05, ∗∗p ≤ 0.01, ∗∗∗p ≤ 0.001, ∗∗∗∗p ≤ 0.0001, n.s. ≥ 0.05. See also Figures S4 and S5.
