Meanwhile, circNcx1 (a circRNA transcribed from the sodium/calcium exchanger 1 (ncx1) gene, which is also called solute carrier family 8 member A1 (slc8a1) gene), was able to regulate cardiomyocyte apoptosis by targeting miR-133a-3p-CDIP1 in 2018 [100], but whether it can regulate myocardial hypertrophy by targeting miR-133a is still unknown. Here, SLC8A1 is linked to cardiac hypertrophy.
