Description |
Anisomycin is a potent protein synthesis inhibitor which interferes with protein and DNA synthesis by inhibiting peptidyl transferase or the 80S ribosome system.

In Vitro |
To examine whether JNK has a core role in colistin-induced neurotoxicity in PC-12 cells, an SP600125 (a highly selective inhibitor of JNK) and Anisomycin (a potent activator) are used in this study. In order to select an appropriate concentration, PC-12 cells are treated with a range of SP600125 (0-80 μM) and Anisomycin (0-20 μM) respectively for 24 h. The results show that the cells viability significantly decreases by SP600125 treatment in a concentration-dependent manner, observed at the concentrations greater than 20 μM (p<0.01). Similarly the cells viability is inhibited by Anisomycin treatment (≥8 μM) (p<0.05) [1].

In Vivo |
Disruption of TNFRp55/p75 attenuates Anisomycin-induced ventricular functional improvements. Anisomycin results in an improvement in left ventricular developed pressure (LVDP), which disappears in animals with disruption of TNFR p55/p75. In addition, the Anisomycin-induced improvement in LVEDP in wild-type animals is eliminated by deletion of TNFR p55/p75. Likewise, disruption of TNFR p55/p75 abrogates the recovery of rate pressure product (RPP) elicited by pretreatment of Anisomycin. TNFR p55/p75-/- mice without Anisomycin treatment do not show differences in cardiac functional recovery compared with the control wild-type mice. There are no significant differences in heart rate between wild-type and TNFR p55/p75-deficient mice. To see whether Nox2 is involved in Anisomycin-induced myocardial protection, Nox2-deficient mice are treated with Anisomycin. The improvement in the LVEDP in Anisomycin-treated mice is eliminated in Nox2-/- mice compared with wild-type mice. In addition, recovery of RPP in wild-type mice treated with Anisomycin is mitigated in Nox2-/- mice. Nox2-/- mice without Anisomycin treatment do not show the difference in cardiac functional recovery compared with wild-type control mice[2].

Cell Assay |
PC-12 cells are seeded in 96-well plates at a concentration of 1×104 cells/well and cultured in an incubator at 37°C with 5% CO2 for at least 12 h prior to exposure to different concentrations of SP600125 (0-80 μM) or Anisomycin (0-20 μM) for 24 h. Subsequently, the culture medium is added to 20 μL of 5 mg/mL MTT working solution and the plate is incubated for 2 h at 37°C. The culture supernatant is removed and the formazan crystals are dissolved in 150 μL DMSO. Finally, the absorbance of each well is measured at 490 nm by a microplate reader. Cell viability is expressed as the percentage of the control group, which is set to 100%[1].

Animal Admin |
Mice[2] Adult male TNFRp55/p75 mice, adult male wild-type C57/BL and homozygous Nox2-/- mice are used in this study. Mice are randomized into six experimental groups that undergo the following treatments,. Animals are divided into six groups: group 1: control ischemia/reperfusion, wild-type mice are injected with DMSO (0.1 mL); group 2: Anisomycin+wild-type mice, wild-type mice are injected with Anisomycin (0.1 mg/kg ip); group 3: Anisomycin+TNFR p55/p75-/- mice, TNFR p55/75-/- mice are injected with Anisomycin (0.1 mg/kg ip); group 4: TNFR p55/p75-/- mice, TNFR p55/75-/- mice are not injected with Anisomycin; group 5: Anisomycin+Nox2-/- mice, Nox2-/- mice are injected with Anisomycin (0.1 mg/kg ip); and group 6: Nox2-/- mice, Nox2-/- mice are not injected with Anisomycin. Later (24 h), the hearts are subjected to 30 min of ischemia followed by 30 min of reperfusion[2].
