        Heart disease, adult and congenital, is the leading cause of morbidity and mortality in the developed world due to inability of existing treatment to replace damaged and lost heart tissue. Heart is one of the least regenerative organs in the body with limited endogenous ability to repair or replace affected cardiomyocytes. The research goal of the Trivedi lab is to identify cellular processes and regulatory mechanisms involved in congenital heart diseases and thereby, cardiac growth and development. Mechanistic insights into embryonic cardiac growth pathways could pave the way to repair the injured embryonic and adult heart.

        Although transcription factors involved in cardiac growth and development have been described, the closely associated chromatin modifiers of this process remain largely unknown. Histone deacetylases (Hdacs) modify chromatin structure to regulate gene expression in the heart and elsewhere. Using knockout murine models and isolated cardiomyocytes, we have characterized chromatin modifying enzymes and signaling pathways leading to cardiomyocyte differentiation (Lewandowski SL et al, Human Molecular Genetics, 2014), proliferation (Trivedi CM et al, Developmental Cell, 2010; Trivedi CM et al, JBC, 2008) and hypertrophic cardiomyopathy (Trivedi CM et al, Nature Medicine, 2007).

        Recently, the Trivedi lab has established a critical interplay between chromatin modifying enzymes and transcription factors during pathogenesis of congenital heart defects (Lewandowski et al, Human Molecular Genetics, 2014). TBX5, the causative gene in the Holt-Oram Syndrome, was the first identified single-gene mutation giving rise to congenital heart defects. Our studies reveal a critical mechanistic relationship between TBX5G125R, a gain-of-function mutation identified in patients with Holt-Oram Syndrome, and Hdac3. We described a specific and novel function of Hdac3 in cardiac progenitor cells during early murine cardiogenesis. We uncover a mechanism whereby Hdac3 deacetylates the transcription factor Tbx5 and represses Tbx5-dependent activation of cardiomyocyte lineage-specific genes to maintain the pluripotent state of cardiac progenitor cells. These discoveries have opened new areas of investigation and contributed to growing appreciation that HDACs are master regulators of cardiomyocyte homeostasis and function.


        Rotation Projects

        Rotation Projects:

        Please contact Chinmay Trivedi ( for information regarding potential rotation projects. We will develop a specific rotation project based on student's interest, background, and goals of the rotation. Students can rotate either for a half- or full-semester.

        Project 1: Characterize progressive lineage restriction of cardiac progenitor cells in murine model.
        Project 2: Identify novel chromatin modifiers regulating specification of murine cardiac progenitor cells. 
        Project 3: Characterize cellular interactions during murine cardiac development and diseases.
        Project 4: Determine novel roles of epigenetic modifications during cardiac diseases.
