introduction/brief CV

Professional Background
Dr Rukhsana Gul is an Associate Professor at Obesity Research Center (ORC), College of Medicine, King Saud University, KSA. Dr Gul has completed her Ph.D. from Department of Biochemistry, School of Medicine, Chonbuk National University, South Korea. Prior to joining ORC, Dr. Gul was working as a Postdoctoral fellow in Diabetes Research Center, Department of Internal Medicine, School of Medicine, University of Missouri, Columbia-MO, USA.
Research Description
Dr Gul has a long-standing interest in the signaling mechanisms activated by the peptide hormone Angiotensin II (Ang II) in normal development and cardiovascular pathology. Her research has taken a new direction recently with the emphasis on understanding the role of different microRNA’s in cardiovascular pathology. Her recent studies in Diabetes Research center, at the University of Missouri, have unraveled a novel role of Nebivolol, a 3rd generation beta adrenergic receptor blocker. During her Ph.D. and Postdoc training at the School of Medicine, Chonbuk National University, South Korea, Dr Gul elucidated a novel signaling pathway of ADP-ribosyl cyclase activation by Ang II in adult rat cardiomyocytes. She also demonstrated that inhibition of ADP-ribosyl cyclase by a small molecule inhibitor, 2,2'-dihydroxyazobenzene (DAB), attenuates Ang II-induced cardiac hypertrophy.
Research interests
Cellular mechanisms of obesity induced cardiac pathologies.
Current Projects
Role of β-adrenergic receptor blockers on amelioration of cardiovascular abnormalities in over-activated renin angiotensin aldosterone system
Differential effects of β-adrenergic receptor antagonists on lipopolysaccharide-induced cardiovascular pathologies.
Effects of Nanoparticles on cardiovascular pathologies induced by different agonists.
Positions available
Dr. Gul is now accepting the volunteer researchers with Master’s or Ph.D. degree in the field of biological sciences, who are interested in learning and actively participating in our ongoing research projects.
Dr Gul is also accepting students requiring a co-supervisor for their Master’s or Ph.D. research project. Students can also be assigned to the ongoing projects depending on their interest and abilities.
