Overview

In the past 12 years my research has focused on investigating novel mechanisms and therapies for cardiac hypertrophy and heart failure in animal models. As a pharmacist I have a special interest in the translation of my findings into human drug therapy for heart disease and I wish to focus my career on contributing to the fascinating and decisive early steps in the long process of drug development.

2001-2003 Masters studies in Egypt: Using advanced biochemical and electron microscopic methods I investigated the role of TNF-α inhibition and antioxidants in protection against doxorubicin-induced cardiomyopathy in rats. My Masters study resulted in 2 publications (Mohamed et al., J Pharm. Pharmacol., 2004 & Mohamed et al., Egy. J. Biochem. Mol. Biol. 2005) which described combination of TNF-α inhibition and antioxidant therapy could protect against the cardiac side effects of this powerful cancer chemotherapy.


2005-2008 PhD studies in Manchester: As a PhD student in the Cardiovascular Medicine research group I continued investigating novel and potentially ‘druggable’ proteins that regulate cardiac hypertrophy and heart failure. In 2005, one of the proteins with unknown function in the heart was the plasma membrane calcium ATPase pump isoform 4 (PMCA4) which pumps calcium out of the heart cell, but does not contribute to contraction/relaxation. Therefore, I decided to explore its role using transgenic and knock-out mouse models, and cellular models and was able to describe a novel role for PMCA4 in regulating cardiac contractility indirectly through modulation of neuronal nitric oxide synthase (nNOS). This work resulted in three publications in highly recognized journals (Williams et al., JBC 2006, Mohamed et al., JBC 2009 and Oceandy et al., Circulation 2009), and several oral and poster presentations at international cardiovascular conferences. 


2008-2011 Post Doctoral training in Manchester: In my first post-doctoral position I expanded my interest from pure molecular biology to live imaging of subcellular compartments, one of the most fascinating developments in modern heart research. To this end, I trained for several months with Prof. M. Zaccolo at the University of Glasgow and started a collaboration with Prof. Michael I. Kotlikoff (Cornell University, USA). Through these collaborations I have developed new tools to assess the changes in local calcium, cAMP and cGMP to explore the role of PMCA4 in modulating compartmentalized cardiac signalling during cardiac hypertrophy and failure. This is carried out using live cell bio-imaging fluorescence resonance emission transfer (FRET) techniques. I independently transferred this complex technology to Manchester (Bio-imaging Facility, Smith Building). Using these methods I first described a locally confined cAMP, cGMP and calcium space in the vicinity of PMCA4 in myocardial caveolae. My postdoctoral work has been highly recognized. I was awarded one of the three Young Investigator Awards (Basic Science) at the European Society of Cardiology Congress in 2010, the largest cardiology conference in the world. In addition, an extensive interview with me was published in Circulation, the leading international cardiovascular journal (European Perspectives in Cardiology. Circulation. 2010; 122(10):f55-60). Several publications will arise from this work; two have been published (Mohamed et al. Methods Mol Biol. 2010;637: 333-42 and Mohamed et al., JBC 2011).
