Introduction: What they say:
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.
What we say:
On the foundation of this interesting finding, Dr L Boominathan PhD, Director-cum-chief Scientist of GBMD, reports that: Molecular therapy for Myocardial Infarction: PPARδ improves myocardial function after myocardial infarction via up-regulation of PNUTS
From Significance of the study to Public health relevance:
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.
From Research Findings to Therapeutic Opportunity:
This study suggests a small molecule-based cardiac regeneration therapy. PPARδ (Peroxisome proliferator-activated receptor (PPAR) δ), by increasing the expression of its target gene, it may increase the expression of PNUTS. Thereby, it may: (1) inhibit DNA damage responses, (2) inhibit telomere shortening; and (3) promote cardiomyocyte survival/regeneration (figure 1).
Thus, by treating cardiac patients with PPARδ activators, one may prevent ageing-associated (or, stress-associated) decline in cardiac function. Together, this study suggests that “PPARδ or its activators or PPARδ activators plus any of the known drugs that prevent/improve myocardial infarction” can be used to improve myocardial function and prevent myocardial infarction.
