RUNX1 and myocardial infarction: Given that RUNX1 expression is increased in the BZ 1-day after MI and is associated with impaired cardiac function (McCarroll et al. 2018; Martin et al. 2023; Kubin et al. 2011; Gattenlohner et al. 2003), it is important to clarify whether pharmacological inhibition of RUNX1 has an impact on infarct size following acute MI.
