Next generation sequencing reveals NRAP as a candidate gene for hypertrophic cardiomyopathy in elderly patients
https://doi.org/10.1101/789065
Hypertrophic cardiomyopathy (HCM) is a heterogenous heart muscle disease predominantly caused by sarcomeric protein encoding genes. However, the cause for a significant number of elderly patients remains unclear. Here, we performed whole-exome sequencing in a South Indian family with an elderly HCM proband. We identified a heterozygous...

i-DHANS: Indian database of healthy aging nucleotide sequences
Manuscript under preparation
Indian database of healthy aging nucleotide sequences (i-DHANS) is the first Indian exome database for healthy aging individuals. It provides comprehensive information of different types of genetic variation on the Indian aging alleles that help to distinguish disease associated mutations. A total of 1500 control participants were analyzed and 94 healthy aging individuals were selected with the...
Myocardin ablation in a cardiac-renal rat model
Sci Rep. 2019; 10;9(1):5872.
Dilated cardiomyopathy (DCM) is a major co-existing form of heart failure (HF) with renal diseases. Myocardin (MYOCD), a cardiac-specific co-activator of serum response factor (SRF), is increased in DCM porcine and patient cardiac tissues and plays a crucial role in the pathophysiology of DCM. Inhibiting the increased MYOCD has shown to be partially rescuing the DCM phenotype in porcine model. However, expression levels of MYOCD in...

Database for Cardiomyopathy: CardioDatabase
CardioDatabase is a comprehensive integrated platform for cardiomyopathy disease, which links dynamic information such as molecular pathogenesis, genetic variants and frequencies, modulation of important pathways, available therapies and therapeutic targets and basic information of disease associated genes. The information was collected in cohesive manner from different databases along with in-house curation. The...
Mir-19b-3p Regulates Autophagy by Targeting Raf-1 During Hypertrophic Cardiomyopathy
Circulation Research. 2018;121:A484
Hypertrophic cardiomyopathy (HCM) is a heterogenous disease predominantly caused by sarcomeric genes. However, 40-50% cases etiology are not known. RAF1 mutations cause syndromic and isolated childhood cardiomyopathies. Functional mutations in untranslated regions (UTRs) of RAF-1 gene are rare, and their role in cardiomyopathy is unexplored. UTRs are important sites for interaction of epigenetic regulators...

Raf1, a nexus for cardiac hypertrophic signaling in human disease
In the current issue of the Journal of Molecular and Cellular Cardiology (July 2011), Dhandapany et al. further explore the ability of Raf1 to regulate hypertrophy of cardiomyocytes. The authors employ three common Raf1 mutations observed in Noonan/LEOPARD syndromes to dissect downstream signaling pathways ultimately impacting myocyte growth control.

Cardiovascular diseases (CVDs) are the leading cause of mortality globally. They are caused by various disorders of the heart and blood vessels. We are interested in understanding three major forms of CVDs including, cardiomyopathies, congenital heart disease and coronary heart disease (heart attacks).
We are a multi-disciplinary team including Geneticists, Clinicians, Bioinformaticians, Engineers, Biochemists, Biophysicists, and Molecular Biologists addressing CVDs through a multi-level approach.
The long-term goals of my group are to explore new genes, mechanisms and relevant drugs that have significant clinical and curative impact on CVDs.
