Pathological cardiac hypertrophy induced by adrenergic overactivation can subsequently develop to heart failure which remains as a leading cause of mortality worldwide. Tanshinone IIA is a lipid-soluble pharmacologically active compound extracted from the rhizome of the Chinese herb Salvia miltiorrhiza, a well-known traditional Chinese medicine used for the treatment of cardiovascular disorders. However, little is know about the effect of Tanshinone IIA on cardiac hypertrophy. The present study was aimed to investigate whether Tanshinone IIA prevents cardiac hypertrophy induced by isoproterenol (ISO) and to clarify its possible mechanisms. Cardiomyocytes hypertrophy was induced by ISO 10 μM for 48 h with or without Tanshinone IIA 10, 30, 100 μM pretreatment, and evaluated by determining the cell size and the expression of ANP, BNP, β-MHC, Calcineurin, and NFATc3 by real-time PCR and western blot. We found that Tanshinone IIA pretreatment attenuated the enlargement of cell surface area induced by ISO in cultured cardiomyocytes. The mRNA level of ANP, BNP and β-MHC was obviously elevated in ISO-treated cardiac cells, which was effectively inhibited by Tanshinone IIA. Moreover, we found that Tanshinone IIA pretreatment could prevent the augment of intracellular calcium transient in ISO-treated cardiomyocytes. The further study revealed that Calcineurin, NFATc3, ANP, BNP and β-MHC proteins were upregulated by ISO in ventricular myocytes, and Tanshinone IIA pretreatment significantly attenuate the increased expression of Calcineurin, NFATc3, ANP, BNP and β-MHC proteins. In summary, Tanshinone IIA attenuated cardiomyocyte hypertrophy induced by ISO through inhibiting Calcineurin/NFATc3 pathway, which provides new insights into the pharmacological role and therapeutic mechanism of Tanshinone IIA in heart diseases.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

D050778 NFATC Transcription Factors A family of transcription factors characterized by the presence of highly conserved calcineurin- and DNA-binding domains. NFAT proteins are activated in the CYTOPLASM by the calcium-dependent phosphatase CALCINEURIN. They transduce calcium signals to the nucleus where they can interact with TRANSCRIPTION FACTOR AP-1 or NF-KAPPA B and initiate GENETIC TRANSCRIPTION of GENES involved in CELL DIFFERENTIATION and development. NFAT proteins stimulate T-CELL activation through the induction of IMMEDIATE-EARLY GENES such as INTERLEUKIN-2.
