Summary of the Literature Regarding Effects of p53 Inhibition on Acute Myocardial Ischemia/Reperfusion Injury.
Species | Protocol of I/R Injury | Protocol of p53 Inhibition | Estimation of Infarct Size | Result | References | |
---|---|---|---|---|---|---|
1 | Male rats | Isolated perfused hearts, Regional I/R | Infusion of PFTα at 10 μmol/L, for 15 minutes before I, for 5 minutes prior to the end of I and continued for 10 minutes to R | TTC staining | IS reduction | 22 |
2 | Male rabbits | In vivo, Regional I/R | Administration of PFTα at 1.5 or 3.0 mg/kg by intraperitoneal injection 30 minutes before I | TTC staining | 1.5 mg/kg: no effect on IS, 3.0 mg/kg: IS reduction | 20 |
3 | Aged male F344 rats (20 months old) | In vivo, Regional I/R | Administration of PFTa at 2.2 mg/kg by intraperitoneal injection 40 minutes before I | TTC staining | IS reduction | 21 |
4 | Male mice (11–14 weeks old) | Isolated perfused hearts Global I/R | As shown in Figure 1A | TTC staining | No effect on IS | Our study |
Abbreviations: I/R, ischemia/reperfusion; PFT, pifithrin; TTC, 2,3,5-triphenyltetrazolium chloride, IS = infarct size.
