Figure 6. Effects of MSCM-Fe3O4@PDA, Fe3O4@PDA and Fe3O4 NPs on ASK1/JNK signaling pathway. (A) Detection of ASK1 and JNK mRNA levels by RT-qPCR. (B) The representative pictures and statistical chart of p-ASK1 and p-JNK protein by immunohistochemistry. (C) Detection of p-ASK1, ASK1, p-JNK and JNK protein by western blot. ap < 0.05 when compared with control, bp < 0.05 when compared with MSCM-Fe3O4@PDA, cp < 0.05 when compared with Fe3O4@PDA.
