Specifically, the expression levels of genes encoding Ca2+ channels (cacna1g), K+ channels (kcna6, kcnj1, kcnj4, kcnq2, and kcnq4), and vesicular acetylcholine transporter (slc18a3) were significantly upregulated in rats with arrhythmia following LA treatment. Here, SLC18A3 is linked to Arrhythmia.
