The immunoreactive score (IRS) of immunohistochemistry for the proliferating cell nuclear antigen (PCNA) was greater in AURKA(V352I) and AURKA(WT) than in control fish at 5 and 7 months. (A) Representative images of immunohistochemistry (IHC) staining for PCNA in control, AURKA(WT), and AURKA(V352I) at 3, 5, 7, 9, and 11 months; (B) Selected enlarged images show the nuclear signals of PCNA from AURKA(WT)—7 M and AURKA(V352I)—5 M; (C) Statistical analysis of PCNA immunostaining IRS score at 3, 5, 7, 9, and 11 months. IRS score of control fish (Tg(fabp10a:EGFP-mCherry) abbreviated as mC, AURKA(WT) and AURKA(V352I) is shown in red (3 M), orange (5 M), green (7 M), purple (9 M), and blue (11 M). Statistical analysis of results was performed using a two-tailed Student’s t-test. The error bar means standard deviation. Asterisks (*) represent the level of significance. * p-value ≤ 0.05; ** p-value ≤ 0.01; *** p-value ≤ 0.001.
