Biosketch

Dr. Jose R. Pinto earned his Ph.D in 2006 from the Federal University of Rio de Janeiro. His research of study was Muscle Biochemistry and Biophysics. He researched as a postdoctoral scholar from 2006 to 2010 at the University of Miami, Miller School of Medicine under the mentoring of Dr. James D. Potter. His postdoctoral research focus was on the Molecular Mechanisms of Inherited Cardiomyopathies. In 2010, Dr. Pinto became a research assistant professor until he joined the FSU College of Medicine Biomedical Sciences Department in 2011.

Research Focus

Cardiac and skeletal muscle regulation and inherited diseases. Molecular basis of striated muscle contraction.

Cardiac/Slow Skeletal Troponin C (C/SSTnC) is the only component of CTn that is expressed and present in both cardiac and slow skeletal muscles. Our research aims at elucidating the physiological consequences of TnC mutants related to Hypertrophic (HCM) and dilated (DCM) cardiomyopathy in slow skeletal muscle. These studies will investigate whether slow skeletal muscle containing C/SSTnC mutations develops skeletal abnormalities similar to those seen in the heart and whether the function of skeletal muscle is altered. Our lab uses innovative approaches including knock-in mice to provide critical insights into this disease in skeletal muscle.
