7、 Anisomycin (a potent activator) are used in this study. In order to select an appropriateconcentration, PC-12 cells are treated with a range of SP600125 (0-80 M) and Anisomycin (0-20 M) respectively for24 h. The results show that the cells viability significantly decreases by SP600125 treatment in

Similarly the cells viability isinhibited by Anisomycin treatment (8 M) (p0.05) 1.体内研究 Disruption of TNFRp55/p75 attenuates Anisomycin-induced ventricular functional improvements.

In addition, the Anisomycin-induced improvement in LVEDP in wild-type animals is eliminated by deletionof TNFR p55/p75. Likewise, disruption of TNFR p55/p75 abrogates the recovery of r

The improvement in the LVEDP inAnisomycin-treated mice is eliminated in Nox2-/- mice compared with wild-type mice. In addition, recovery of RPP inwild-type mice t
