Antibiotic Proved Protective against Heart Tissue Damage and Cell Death – Research Find

Antibiotics - decreased cell death and heart attack injury by maintaining Adenosine Tri Phosphate (ATP) levels in the cells//.

A study with rapamycin - an antibiotic (used to trigger organ survival in transplant patients) by Virginia Commonwealth University researchers have revealed that heart tissue damage after an acute heart attack might be protected by rapamycin.

In the July issue of the Journal of Molecular and Cellular Cardiology, the official publication of the International Society for Heart Research, researchers demonstrated for the first time that pretreatment with a clinically relevant dose of rapamycin induces a protective effect against heart attack injury and reduces programmed cell death.

Researchers believe through the opening of the mitochondrial KATP channel of heart cells, rapamycin enables cells to maintain ATP levels. Mitochondria are cellular organelles critical for converting oxygen into ATP, the key fuel for cellular function.

‘Rapamycin may one day be beneficial as a potential therapeutic strategy to limit cell death caused by ischemia or reperfusion injury, and possibly long-term prevention of ventricular remodeling – the changes in size, shape and function that may occur to the left ventricle of the heart,’ said Rakesh C. Kukreja, Ph.D., professor of medicine and Eric Lipman Chair of Cardiology at VCU. Kukreja is lead author of the study.

Rapamycin blocks protein synthesis by inhibiting the mammalian target of rapamycin (mTOR), an essential component in the pathway of the cell cycle progression. The drug has been found to be important in transplant medicine and especially in kidney or heart transplantation. Additionally, Kukreja said that because of the antibiotic’s antigrowth properties, rapamycin effectively reduces coronary restonosis, the abnormal narrowing of a blood vessel. In coronary angioplasty, stents coated with rapamycin are implanted to reduce the risk of restonosis.

‘A significant clinical question will be whether or not rapamycin coated stents can be utilized in patients to favorably affect damaged heart muscle beyond the blockage causing a heart attack,’ said George W. Vetrovec, M.D., chair of cardiology at VCU’s School of Medicine, and co-author of the study.

For the last several years, Kukreja and his colleagues have studied a class of erectile dysfunction drug known as phosphodiesterase-5 inhibitors as part of ongoing research into heart protection. The team first investigated Viagra?, generically known as sildenafil, and more recently, Levitra?, generically known as vardenafil, and found that both compounds showed protective effects in the heart during experimental heart attacks in animal models.

This work was supported by grants from the National Institutes of Health, and American Heart Association, National Center.
