Abstract

Hyperglycemia caused by diabetes mellitus could increase the risk of diabetic cardiomyopathy. However, to the best of our knowledge, the underlying mechanism of this process is still not fully explored. Thus, developing ways to prevent hyperglycemia can be beneficial for diabetic patients. The present study was designed to investigate the influence of metoprolol and bisoprolol on the cardiomyocytic hypertrophy of neonatal rat cardiomyocytes. Cardiomyocytes were cultured in two types of media: One with low glucose levels and one with high glucose levels. Cardiomyocytes cultured in high glucose were further treated with the following: A protein kinase C (PKC) inhibitor, an NF‑κB inhibitor, metoprolol or bisoprolol. The pulsatile frequency, cellular diameter and surface area of cardiomyocytes were measured. Protein content and [3H]‑leucine incorporation were determined, atrial natriuretic peptide (ANP), α‑myosin heavy chain (α‑MHC) and β‑myosin heavy chain (β‑MHC) mRNA levels were calculated by reverse transcription‑quantitative PCR, while the expression and activation of PKC‑α, PKC‑β2, NF‑κB, tumor necrosis factor‑α (TNF‑α), and c‑fos were detected by western blotting. Metoprolol or bisoprolol were also used in combination with PKC inhibitor or NF‑κB inhibitor to determine whether the hypertrophic response would be attenuated to a lower extent compared with metroprolol or bisoprolol alone. Cardiomyocytes cultured in high glucose presented increased pulsatile frequency, cellular diameter, surface area, and protein content and synthesis, higher expression of ANP and β‑MHC, and lower α‑MHC expression. High glucose levels also upregulated the expression and activation of PKC‑α, PKC‑β2, NF‑κB, TNF‑α and c‑fos. Metoprolol and bisoprolol partly reversed the above changes, while combined use of metoprolol or bisoprolol with PKC inhibitor or NF‑κB inhibitor further ameliorated the hypertrophic response mentioned above to lower levels compared with using metroprolol or bisoprolol alone. In conclusion, metoprolol and bisoprolol could prevent hypertrophy of cardiomyocytes cultured in high glucose by the inhibition of the total and phospho‑PKC‑α, which could further influence the PKC‑α/NF‑κB/c‑fos signaling pathway.
