Figure Lengend Snippet: Effect of a 3-day decrease in PTBP1 protein level in HT22 cells on cell differentiation and maturation. (A) Representative western blotting of MAP2, PTBP1, βIII-Tubulin, NeuN and GAPDH (n=4 per group). Quantitative statistical analysis results of (B) MAP2, (C) PTBP1, (D) βIII-Tubulin, (E) NeuN. (F) Representative immunofluorescence staining images and quantitative statistical analysis results of (G) βIII-Tubulin and (H) PTBP1. (I) Representative immunofluorescence staining images and quantitative statistical analysis results of (J) NeuN and (K) PTBP1. (L) Representative immunofluorescence staining images and quantitative statistical analysis results of (M) MAP2 and (N) PTBP1 (n=3 per group). Scar bar, 50 µm. ** P<0.01, *** P<0.001 and **** P<0.0001. PTBP1, polypyrimidine tract-binding protein 1; MAP2, microtubule-associated protein 2; NC, negative control; si, small interfering; ns, not significant.
