The invention discloses a research method of MS-275 acting on acute
myocardial ischemia reperfusion injury. The research method comprises the following steps: step I, performing
ligation of an anterior descending
branch of a
left coronary artery of an SD male bandicoot to construct a bandicoot
acute MI / RI model; step II, observing the action of the MS-275 in an MI / RI
acute stage of the bandicoot;and step III, discussing a
molecular mechanism of the MS-275 on bandicoot MI / RI protection action. According to the research, through constructing the bandicoot
acute MI / RI model and combination within vivo and vitro experiments, the following research objectives are achieved: (1) observing the
acetylation level of
histone, and expression of HDAC1 and
microRNA-210(miR-210) in
cardiac muscle tissue of the bandicoot at the MI / RI
acute stage; (2) confirming that the MS-275, a novel HDACI type selective
depressant, has protection action on MI / RI of the bandicoot and influence on the
acetylation level of the
histone and expression of HDAC1 and miR-210 in tissue of a
myocardial infarction region of the bandicoot subjected to
myocardial ischemia reperfusion; and (3) disclosing a specific
molecular mechanism that the MS-275 improves MI / RI of the bandicoot from the angle of miRNA epigenetic regulation, and providing an important theory and experiment basis for MI / RI treatment with HDACi.
