Muge N. Kuyumcu-Martinez received her Ph.D. at Baylor College of Medicine studying mechanisms by which positive-strand RNA viruses utilize to target RNA binding proteins involved in host mRNA translation. She pursued her post-doctoral training at Baylor College of Medicine working on alternative splicing regulation by RNA binding proteins during heart development and in cardiac complications of muscular dystrophy. She was promoted to an Instructor position at Baylor College of Medicine. In 2010, she was recruited as a tenure track Assistant Professor to the University of Texas Medical Branch. Since then, she has received the prestigious March of Dimes Basil O'Connor Starter Scholar Award and obtained numerous federal and private grants. She has published several high impact research papers and review articles regarding the role of RNA binding proteins in human heart diseases. She has served as an ad hoc member of study sections for American Heart Association and NIH. She is currently a member of American Heart Association and RNA society.
Our laboratory’s main focus is to understand gene regulation by RNA binding proteins in the heart. We utilize state of the art RNA-sequencing technologies combined with mouse genetics, molecular and cellular biology techniques to achieve our goals.
- Identifying RNA binding proteins and their target RNA networks are essential for proper heart development and function
- Elucidating how dysregulation of these RNA networks and RNA binding proteins leads to congenital and adult heart diseases
- Defining novel methods to restore essential gene regulatory RNA networks for prevention or treatment of human heart diseases
We are currently pursuing two different aspects of gene regulation by RNA binding proteins in the heart.
1. RNA binding proteins and their target RNA networks essential for heart development
Congenital heart defects can lead to childhood deaths and life-long cardiovascular complications. Recent studies linked mutations in RNA binding proteins to congenital heart defects. Not much is known regarding the role of RNA binding proteins in cardiovascular development. The RNA binding protein RBFOX2 is mutated in patients with congenital heart defects. It is unclear how RBFOX2 contributes to mammalian heart development. We are systematically investigating how loss of Rbfox2 in mouse cardiac progenitor cells impact early cardiovascular development and identifying its target RNA networks in the embryonic heart.
RNA binding proteins can impact gene expression and function by regulating pre-mRNA splicing, cleavage and polyadenylation, mRNA stability, localization and translation. However, RNA regulatory networks are poorly defined in the embryonic heart. We are focused on identifying essential RNA regulatory networks regulated by RNA binding proteins in the embryonic heart with direct impact on cardiovascular development. These findings will provide insights into better understanding congenital heart defects and may lead to novel ways to prevent life-long cardiovascular complications.
2. Dysregulation of gene regulatory RNA networks in diabetes
We identified several different RNA binding proteins that are dysregulated in diabetic hearts. We are further pursuing the consequences of these changes in these RNA binding proteins and their target expression and function in the diabetic hearts. We are currently testing antisense oligo based therapy to correct aberrant gene expression by targeting pre-mRNAs in order to find novel ways to. prevent or treat diabetic heart complications using mouse models.
Diabetes is a costly health care problem affecting 8.3% of the US population. The majority of the diabetes patients die from cardiovascular complications. Defining RNA regulatory networks that contribute to aberrant gene expression in diabetic hearts may reveal novel ways such as oligo-based therapy to correct these defects and ultimately prevent/treat cardiovascular complications of diabetes.
