A recent study from the Institute for Cardiovascular Regeneration, Centre of Molecular Medicine, Frankfurt, Germany shows that “MicroRNA-34a regulates cardiac ageing and function.” This study was published in the 7 March 2013 issue of Nature by Prof Dimmler, Boon, and others.
On the foundation of this interesting finding, Dr L Boominathan PhD, Director-cum-chief Scientist of GBMD, reports that: Molecular therapy for Myocardial Infarction: Sirtuin-7 improves myocardial function after myocardial infarction via up-regulation of PNUTS/PPP1R10 (Serine/threonine-protein phosphatase 1 regulatory subunit 10)
Given that: (1) cardiovascular disease is the leading cause of death worldwide; (2) in India, in 2004, 14.6 lakhs deaths (14% of total deaths) were due to ischemic heart disease; and (3) the global economic cost spent in the treatment of cardiovascular disease in 2011 was little more than 10 billion US dollars, there is an urgent need to find: (i) a way to induce regeneration of adult cardiomyocytes that were lost in Myocardial patients; (ii) a cheaper alternative to the existing expensive drugs; and (iii) a side-effect-free drug.
This study suggests a small molecule-based cardiac regeneration therapy. HMGI-C, by decreasing the expression of its target gene, it may increase the expression of PNUTS/PPP1R10. Thereby, it may: (1) inhibit DNA damage responses, (2) inhibit telomere shortening; and (3) promote cardiomyocyte survival/regeneration.
Thus, by treating myocardial patients with Sirtuin-7 activators, one may prevent ageing-associated (or, stress-associated) decline in cardiac function. Together, this study suggests that pharmacological formulations encompassing “Sirtuin-7 activators” may be used to improve cardiac function after myocardial infarction.
