Figure Lengend Snippet: Upregulation of the transcription factors POU3F2 and NTF3 during neuronal differentiation of NT2D1. a The protocol for neuronal induction of NT2D1 cells is schematized. b β3-tubulin staining for neuronal cells in NT2D1 cells untreated (non) and treated with neuronal induction medium at the indicated time points. c Quantification of β3-tubulin-positive cells. d Immunoblotting analysis for POU3F2, POU3F3, β3-tubulin, and NTF3 in NT2D1 cells untreated or treated with neuronal induction medium at the indicated time points. The values show the expression relative to that of untreated cells (to which a value of 1 was assigned). e Microarray analysis showed that neuronal induction for 6 h increased the expression of NTF3 and GADD45 in NT2D1 cells. f NTF3 mRNA expression after neuronal induction was analyzed by real-time PCR. The levels of mRNA were calculated as the relative expression compared with that of non-induced NT2D1 cells. GAPDH mRNA was used as a control. * p < 0.05; *** p < 0.001. g Phospho-TrkC (Tyr820) staining in treated and untreated NT2D1 cells.

Figure Lengend Snippet: Identification of the POU3F2 binding site on the NTF3 promoter. a Transcription factor response elements predicted by the Transcription Element Search System for the nucleotide sequence of the NTF3 promoter region (− 1823 to + 243). The transcription start site is indicated as + 1. b Comparison of NTF3 promoter sequence conservation between different species. c Biotin-labeled oligonucleotides containing the intact or mutated POU3F2 binding site were hybridized with total lysates prepared from NT2D1 cells. The POU3F2-DNA complexes were precipitated by streptavidin agarose beads. POU3F2 was analyzed by Western blot analyses. The input of nuclear extracts was used as loading control. Three independent experiments were performed. d Chromatin was prepared from NT2D1 cells treated with induction medium for 0, 2, and 6 h. Cell lysates were mixed with antibodies against POU3F2 or IgG and then precipitated. The precipitates were analyzed by PCR for the presence of the NTF3 promoter sequence. The DNA purified from the sonicated chromatin was directly analyzed by PCR using the ChIP primer, which was used as an input control (Input). e The values of the ChIP DNA were normalized to that of the NT2D1 cells at 0 h (as a control). Values of fold-change over the control are presented as mean ± SEM of three independent experiments for d . * p < 0.05 compared with the control
