Representative immunoblots and quantitative analysis of synaptosomes from cultured mutant hippocampal neurons in the presence and absence of FK506 treatment showing a selective increase in total GluA1 and GluA1 S845 phosphorylation [pGluA1(S845)] (n=10 experiments, *p<0.05 and ***p<0.001, unpaired two-tailed student's t-test).

Effect of FK506 on protein expressions of p-JNK, p-ERK, cytosolic cytochrome c and cleaved caspase-3. Cells were incubated either in the absence of (control) or in the presence of FK506 (12.5, 25 and 50 μM) for 8 h, and protein expressions of p-JNK, p-ERK, cytosolic cytochrome c and cleaved caspase-3 were determined using western blotting. Increasing expressions of p-JNK, p-ERK, cytosolic cytochrome c and cleaved caspase-3 were observed in fibroblasts after FK506 treatment at increasing concentrations, and peaked at the concentration of 50 μM.

TH2849 protects mitochondrial from damage induced by MPP+. Representative confocal image of MDA‐MB‐231 cells incubated with treated with 1‰ DMSO, 10 μmol/L MPP+ alone, or co‐treated with 1 μmol/L rapamycin, 10 μmol/L FK506, 1 μmol/L TH 2451, and 1 μmol/L TH 2849 for 24 h, and then, the immunofluorescence experiment was performed with the primary antibody against (A) Tom20 and (D) NF‐Κb, or the fluorogenic probe DCFH‑DA was used to detect the ROS levels (C). B, EGFP‐LC3 transfected PC12 cells were treated with 10 μmol/L MPP+ alone or co‐treated with 1‰ DMSO, 1 μmol/L rapamycin, 10 μmol/L FK506, 1 μmol/L TH 2451, and 1 μmol/L TH 2849 for 24 h. Mitochondrial transmembrane potential (ΔΨm) was detected by JC‐1. All the substances were dissolved in DMSO. Scale bars: 10 μm. n = 3

Effect of FK506 on fibroblast proliferation in vitro. Rat skin fibroblasts were treated with increasing concentrations of FK506 for 8 h. The viable cells were measured by CCK-8 assay. FK506 inhibited fibroblast proliferation in a dose-dependent manner. Cell viability reached a relatively minimal level at 75 μM. *P<0.05, **P<0.01 compared with control. All experiments were preformed three times with comparable results
