Key Points

This research aims to clarify the mechanisms behind the elevated TRAF6 expression in myocardial ischemia-reperfusion injury.
Examined the role of TIF1β in stabilizing TRAF6 during myocardial ischemia-reperfusion injury.
Analyzed TRAF6 SUMOylation as a mediating factor.
Evaluated heart function post-injury in relation to TRAF6 expression levels.
TRAF6 was found to be significantly elevated in myocardial ischemia-reperfusion injury models.
TIF1β was linked to the stabilization of TRAF6 through SUMOylation.
Inhibition of TRAF6 expression correlated with improved heart function outcomes.

Abstract

Myocardial ischemia-reperfusion injury (MIRI) exacerbates myocardial damage, resulting in a further decline in heart function. Abnormally high TRAF6 expression was reported in MIRI. However, what actually causes the abnormally elevated expression of TRAF6 in MIRI is still unclear and needs further study.
