Fig. 6. Alterations in gene expressions in the gill and DG of mussel under MP stressor.
A Immunostaining for antibodies against DAPI (blue), pAKT (green), pERK (red) in the gill and DG of day 14–100 mg/L microsphere and microfiber groups. B Quantification for expression level of pERK and pAKT in gill and DG of each group. One-way ANOVA multiple comparison was performed to calculate significance (**p < 0.01, ***p < 0.001, n = 5). C Transcription level of target genes of the gill in day 14–100 mg/L microsphere and microfiber groups. Data are presented as mean ± SD. One-way ANOVA with Turkey’s post hoc test was conducted to calculate significance (*p < 0.05, **p < 0.01, ***p < 0.001, n = 3). n.s; not significant. D Schematic depicting the molecular pathways functioning in spherical and fibrous morphotypes MP-induced stress in mussels.
