One study showed that the expression of three lncRNAs, the potassium voltage-gated channel, KQT-like subfamily, member 1 opposite strand/antisense transcript 1 (KCNQ1OT1), hypoxia-inducible factor 1A antisense RNA 2 (HIF1A-AS2) and MALAT1 were increased in PBMC samples in MI patients, whereas lncRNA ANRIL expression was reduced [184]. Here, CDKN2B-AS1 is linked to myocardial infarction.
