Hadassah and Boston Cardiologists Identify Factor Which Exacerbates Heart Failure
In a series of experiments, Dr. Ronen Beeri, Director of the Cardiovascular Research Center at the Hadassah Medical Center, and Dr. Robert Levine, Senior Physician at Massachusetts General Hospital in Boston, have demonstrated that mitral regurgitation augments the remodeling process occurring after a myocardial infraction which, in turn, exacerbates further heart failure.

They have also discovered that repairing the mitral regurgitation early enough may reverse these deleterious processes, while delayed repair may not. The two physicians have now begun to explore the cellular processes which cause the individual cells to fail. In what may hold promise for the future, they have utilized gene therapy techniques in a sheep model of heart failure to implant a gene for the Sarcoplasmic reticulum Ca (+2)-ATPase ( SERCA2a), which controls a key process in the cell's calcium signaling. The sheep which underwent gene therapy had upregulated levels of SERCA2a, which led to better function and lesser remodeling. They exhibited improved contractility, smaller heart volumes, and activation of cellular pathways that lead to better heart compensation.
Hadasit, Hadassah’s Technology Transfer Arm, Reviews
When the Hadassah University Medical Center’s physicians suggest a
solution to a medical problem which can lead to the development of a new
medicine or product, Hadasit, Hadassah’s technology transfer arm, explores its
feasibility and supports the promotion of those viable ideas with innovation
potential. Although 2012 has been “a year full of challenges for the life
science industry,” says Einat Zisman, Hadasit’s Chief Executive Officer,
Hadasit still signed 125 agreements for clinical trials, all to be done at
Hadassah. In addition, Hadasit signed 15 agreements for cooperation and
commercialization of technologies that were developed at Hadassah. Click here
