XIST and myocardial infarction: The qRT-PCR results qRT-PCRs showed that the expression levels of NEAT1, KCNQ1OT1, XIST, FCER1G, and TYROBP in patients with MI were significantly greater than those in healthy individuals, and these results are consistent with the results of previous literature.[5,33–35] Our study further supports the functional studies of lncRNAs in MI and provides a new therapeutic target for the treatment of MI.
