However, AMO-1 infection reversed the A-TP-induced upregulation of miRNA-1 to approximately 49% of the pacing group (Figure 1A), and recovered the expression levels of KCNE1 and KCNB2 (mRNA: to approximately 1.2-fold and 1.7-fold of the pacing group, respectively) (Figure 2). Here, KCNB2 is linked to infection.
