One of the transcription factors for the myosin gene is the same as that for the sarcoplasmic reticulum pump, suggesting that there is a common aging link between the two cellular mechanisms.
As the heart ages, these free radicals can greatly alter how well the cellular calcium pumps on the sarcoplasmic reticulum work.
In the aging heart, free radicals damage proteins, membranes, and calcium pumps on the sarcoplasmic reticulum that myocytes need to produce contractions.
Sarcoplasmic reticulum (SR) plays a critical role in the maintenance of [Ca.
Pra-c thus has a protective effect on ischemia reperfusion damage of myocardial cells, and may act on the myocardial cell membrane and sarcoplasmic reticulum calcium pump.
Pra-c had a clear effect on SHR blood pressure, and reversed SHR ventricular remodeling by upregulating the gene expression of sarcoplasmic reticulum PLB.
