Erratum to: Novel function of PIWIL1 in neuronal polarization and migration via regulation of microtubule-associated proteins

After publication of this article [1], the authors noticed two errors in Figs. 2e and 3e.

Fig. 2
figure1

PIWIL1 is required for the multipolar–bipolar transition of postmitotic neurons. a, d Morphology of labeled neurons in different cortical regions 3 or 5 days post-IUE with siRNA 1. b, e Traces of labeled neurons 3 or 5 days after IUE respectively. c, f Percentage of bipolar cells (white arrows) in different cortical regions. Data are from at least 3 independent IUE experiments. g Typical morphology of labeled mouse neurons in the IZ 3 days after IUE with RNAi 2 or RNAi 2 plus HIWI compared with individual control plasmid. h Percentage of bipolar cells at the IZ of electroporated mouse cortex. Scale bar, 30 μm. Error bar, SEM, **P < 0.01, ***P < 0.001 (Student’s t-test)

Fig. 3

PIWIL1 knockdown impairs polarization of cortical neurons ex vivo. a Diagram of the ex vivo assay. b, c Average numbers of primary neurites of electroporated cells. d Immunostaining: cultured neurons with PIWIL1 knockdown exhibited multipolar morphology and lower levels of Tau but not Tuj1. e Average neurites’ fluorescence intensity of Tau in GFP+ neurons. Scale bar, 20 μm. Error bar, SEM, *P < 0.05, ***P < 0.001 (Student’s t-test)

The images provided for Fig. 2e in squares ‘Scramble upCP’ and ‘Scramble IoCP’ were incorrect. The correct version of Fig. 2 is included in this erratum.

In Fig. 3e, the label ‘RNAi 4’ was missing from the x axis. The correct version of Fig. 3 is also included in this erratum.
