TRPV3 protein, cardiac hypertrophy marker proteins (BNP and β‐MHC) and autophagy associated proteins (Beclin‐1 and LC3‐II) were up‐regulated, as well as, miR‐103 expression and autophagy associated proteins (p62) were down‐regulated in cardiac hypertrophy models in vivo and in vitro respectively. This evidence concerns the gene NPPB and cardiac hypertrophy.
