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: VEGF-B (Vascular endothelial growth factor B) inhibits DNA damage responses, induces telomerase expression, inhibits telomere shortening, and promotes cardiomyocyte survival 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) the raise of death rate, due to cardiovascular disease, has increased from 123 lakhs in 1990 to 173 lakhs in 2013; (3) 85% of people over 80 years are susceptible to cardiovascular diseases;(4) in India, in 2004, 14.6 lakhs deaths (14% of total deaths) were due to ischemic heart disease; (3) the death due to cardiovascular disease is higher in low-to-middle income countries compared to developed countries; (4) the global economic cost spent in the treatment of cardiovascular disease in 2011 was little more than 10 billion US dollars; (5) an alarming number of people, such as 230 lakhs people, will die from cardiovascular diseases each year by 2030, there is an urgent need to find: (i) a way to induce regeneration of cardiomyocytes that were lost in Myocardial patients; (ii) a cheaper alternative to the existing expensive drugs; and (iv) a side-effect-free Natural product-based drug.
From Research Findings to Therapeutic Opportunity:
This study provides a small molecule-based therapy for myocardial infarction. VEGF-B (Vascular endothelial growth factor B), by increasing the expression of its target genes, it may increase the expression of PNUTS (figs.1-2) . Thereby, it may: (1) inhibit DNA damage responses, (2) increase telomerase expression, (3) inhibit telomere shortening; (4) promote cardiomyocyte survival/regeneration; (5) decelerate ageing; and (6) extend life span (fig 1).
Thus, by treating myocardial patients with VEGF-B (Vascular endothelial growth factor B), one may prevent ageing-associated (or, stress-associated) decline in cardiac function. Together, this study suggests that pharmacological formulations encompassing “VEGF-B or its activators or VEGF-B activators in combination with any of the known drugs that improve myocardial function” may be used to improve cardiac function after myocardial infarction (fig. 3).
