Figure Lengend Snippet: Generation and feature of PCM1 KO RPE1 cells. (A) The PCM1 KO RPE1 cells were coimmunostained with antibodies specific to PCM1 (cyan) and centrin-2 (magenta). (B) The PCM1 KO cells were subjected to immunoblot analyses with antibodies specific to PCM1 and GAPDH. (C) The PCM1 KO cells were subjected to immunoblot analyses with antibodies specific to PCM1, CEP290, OFD1, CEP90, CEP131, and GAPDH. (D) The PCM1 KO cells were cultured in a serum-deprived medium for 48 h and coimmunostained with antibodies specific to acetylated tubulin (magenta), along with PCM1, CEP290, OFD1, CEP131, and CEP90 (cyan). (E) Centrosome intensities of PCM1, CEP290, OFD1, CEP131, and CEP90 were determined. (F) The PCM1 KO cells were coimmunostained with antibodies specific to centrin-2 (magenta), along with CEP250 and CROCC (cyan). (G) Centrosome intensities of CEP250 and CROCC were determined. (H) The PCM1 KO cells were subjected to immunoblot analyses with antibodies specific to CEP250, CROCC, and GAPDH. (I) The FLAG-PCM1-expressing cells were coimmunostained with antibodies specific to PCM1 (cyan) and centrin-2 (magenta). (A, D, F, and I) Scale bars, 10 μm; inset scale bars, 2 μm. (E and G) More than 30 cells per group were counted in three independent experiments. Within each box, the black center line represents the median value, the black box contains the interquartile range, and the black whiskers extend to the 10th and 90th percentiles. Statistical significance was determined using one-way ANOVA with Tukey’s post hoc test (***, P < 0.001; n.s., not significant). Source data are available for this figure: .
