Prabodh Sadana, Ph.D.

Assistant Professor of Pharmaceutical Sciences

Dr. Sadana joined the Department of Pharmaceutical Sciences in November 2009. He received his Bachelors in Pharmacy, University of Delhi, New Delhi, India in 2000. In 2002, he received his Masters in Pharmacy (Pharmacology) from the University of Delhi, New Delhi, India. During his masters tenure, he was an instructor, Pharmacology course to the third year Bachelors of Pharmacy students at University of Delhi, New Delhi, India . In 2007, Dr. Sadana received his Ph.D. degree in Pharmacology, University of Tennessee, Memphis, TN.

He then worked for two years as a Post Doctoral Research Associate at St. Jude Children's Research Hospital, Memphis, TN.

Research Interests

Primarily my research interests lie in nuclear receptor (NR) physiology and pharmacology. Nuclear receptors are a big class of ligand activated transcription factors with 48 identified members in this class. These include proteins such as thyroid hormone receptor, glucocorticoid receptor, estrogen Dr. Prabodh Sadana in Labreceptor, and androgen receptor as well as a number of orphan receptors with yet unidentified physiological ligands and function. All members of this superfamily share a modular structure and many share analogous molecular mechanism of action. Currently accepted model of NR action involves co regulator exchange at the C terminus of the DNA bound receptor. A great deal of specificity and complexity of NR actions is governed by differential coactivator recruitment at target gene promoters. The broad focus of my research is studying transcriptional responses to nuclear hormone receptors which are hormone activated nuclear receptors. Currently, the primary nuclear receptor of interest in my lab is the thyroid hormone receptor (THR).

Thyroid hormone is an essential endocrine hormone with broad effects in growth, development and metabolism. The genomic effects of T3 are regulated by thyroid hormone receptor (THR) bound to the TRE sequences in the promoters of its target genes.  My lab is interested in delineating the molecular mechanisms of thyroid hormone action, its functional physiological consequences and developing means to modulate its activity and function. Among areas of active interest are:

  • Molecular mechanisms that correlate thyroid hormone dysfunction with metabolic and cardiovascular effects.
  • Regulatory mechanisms controlling expression of a and ß isoforms of the thyroid hormone receptor and means to modulate their activity.
  • Role of specific coactivators in thyroid hormone action and means to modulate their activity and function.


Another intriguing aspect of NR biology pertains to the role of coactivators in NR function. Of particular interest to me is the PGC-1 coactivator family (PPARg coactivator). My lab is actively looking at underlying themes governing the role of PGC coactivators in normal physiology and disease.

Lab team results

We are carrying out integrated studies involving the use of various biochemical, cell biology, molecular biology and chemical biology approaches as well as animal models to address these issues.
