Research Expertise and Experience:

Postdoctoral Research Scientist August 2007­ June 2009: Working as a Postdoctoral Research Fellow in Dr. John Mariadason's Oncology research laboratory at Montefiore Medical Center, the university hospital for the Albert Einstein College of Medicine. The primary focus of my work is to determine the mechanisms of action of chemotherapeutic agents used in the treatment of colon cancer, with the ultimate goal of identifying biomarkers which can predict likelihood of response of individual patients to specific chemotherapeutic agents. Specifically, I have been investigating the mechanisms by which HDAC inhibitors induce apoptosis in colon cancer cells and

identifying genomic biomarkers predictive of response to these agents. Recently tissue microarrays were developed to analyze large number of human colon cancer biopsy sections, xenografts and mouse tissues from mouse model of colon cancer. Research Associate October 2006­ June 2007: Worked as a Research Associate in the laboratory of Dr. Mary E Fabry, Professor of Medicine and Ronald Nagel, Professor of Medicine, Albert Einstein College of Medicine, Bronx, New York. Work involved research on acute chest syndrome (ACS) which is a common cause of death in sickle cell disease. Postdoctoral Research Fellow May 2006­October 2006: Volunteer/ Postdoctoral Research Fellow, Montefiore Medical Center, Bronx, New York. Since May 2006-Oct. 2006: Worked as a volunteer on two colon cancer-related projects in the laboratory of Dr. John Mariadason. 1. Determination of the molecular mechanisms by which HADC-inhibitors induce apoptosis and differentiation in colon cancer cell lines in vitro. HDAC inhibitors are a novel class of chemotherapeutic agents presently undergoing phase I and II clinical trial to determine efficacy in a variety of hematopoietic and solid tumors. Previous studies in the laboratory have identified colon cancer cell lines sensitive and resistant to HDAC inhibitor-induced apoptosis and cell differentiation. The goal of this study is to understand the molecular basis for this differential sensitivity. 2. Application of a Systems Biology approach for predicting response of human colon tumors to chemotherapeutic agents. The overall goal of this ongoing study is to determine whether a combination of gene expression profiling, methylation profiling and Comparative Genome Hybridization (CGH) can identify molecular patterns predict likelihood of colon tumors undergoing relapse and response to chemotherapy. Harvard Fellow of Pediatric Medicine and Developmental Immunology 2000-2005: Research Fellow, Department of Pediatrics, Laboratory of Developmental Immunology, Harvard Medical School (HMS) & Massachusetts General Hospital (MGH), Boston, MA. The overall goal of my studies as a post-doctoral fellow in the laboratory of Dr. Thilo Stehle at HMS and MGH was to study the interactions between viruses and receptors, in order to describe mechanisms of viral attachment to target cells and to provide a basis for vaccine and drug design. 1. Structural analysis of the receptor of measles virus Signaling lymphocytic activation molecule (SLAM). The goal of this project was develop a foundation for the development of improved therapies against measles virus, by determining the crystal structure of SLAM. A virus that results in a rash, cough, runny nose, fever, and eye irritation, and can lead to ear infection, pneumonia, seizures, brain damage, and death causes measles. Despite available vaccines, measles is still a major cause of death worldwide, and also a continued cause of serious health problems in the United States and other developed countries. This is evidenced by the recent, massive outbreak of measles in Italy in the year 2002. Measles virus infects human cells by binding to a molecule on the cellular surface known as SLAM. I succeeded in expressing and purifying the SLAM protein, and I was actively engaged in crystallizing and determining its structure, when my PI Dr. Stehle, accepted a position in his native Germany. 2. Determination of the crystal structure of the Lymphotrophic Papovavirus (LPV) protein. LPV is an important member of the family of polyoma viruses, which is double stranded DNA virus, plays a critical role in the development of human warts, cervical cancer and tumors in certain animals. The mechanism by the LPV virus binds to its cell surface receptor is not clearly understood. I successfully expressed, purified and crystallized the LPV protein.

Doctoral Research Student 1995-1999: Doctoral Research Student, North East Wales Institute (NEWI), University of Wales, Department of Biochemistry & Biotechnology. I completed my PhD in the laboratory of Dr. Glenn Morris at the University of Wales. The main objective of my thesis was to identify new potential immunogenic regions within the dystrophin protein by analyzing turn predicted regions, four flexible hinge regions and computer predicted regions of high hydrophilicity and antigenicity indices. I then synthesized and purified peptides of these regions to produce monoclonal antibodies. Dystrophin was chosen as a disease related model protein for the study. The region specific peptide antibodies were produced to avoid long and time consuming epitope mapping procedure. The approach can be applied to other proteins where antigenic determinants are still a mystery. Dystrophin is a protein, which is absent in patients with early childhood Duchenne muscular dystrophy (DMD), and defectively or abnormally expressed in middle and old age group Becker muscular dystrophy (BMD) patients. BMD is rare X-linked genetic disease which can develop in any adult of age forty or over without any family history and cause death within next few years. There is presently no treatment available for these severe muscle-wasting diseases. I produced 13 monoclonal antibodies against flexible hinges, WW domain, and ZZ domain regions of dystrophin during this research project were first reported monoclonal antibodies against these regions. These antibodies are presently being evaluated for better understanding of protein, diagnosis of the disease and also in gene therapy studies for monitoring re-expression of the dystrophin protein. Please check list of monoclonal antibodies for muscular dystrophy research from CIND supported by MDA, USA, ( Consultant Clinical Biochemist and Pathology Laboratory Director 1988-1995: Clinical Biochemist and Pathology Laboratory Director, POLYCLINIC Dr. Saifullah Jan, SA. This is a privately owned Poly Clinic. The patient's volume was more than hundred patients a day. I established this lab in 1988 and was a Director of the lab until 1995. Clinical research projects conducted during this time were as follows. 1994: Participated in " Blood Lipid Level Survey NIDDM patients" The population of various nationalities in the S.A. The project was sponsored by a pharmaceutical firm Parke-Davis. The instrument I used was Cholestech L.D.X. Lipid Analyzer from Cholestech Corporation, Hayward, USA. 1992-1993: Participated in "Cholesterol Level Survey" of the population in SA. This study included Cholesterol level Check-up of normal, hypertensive and, diabetic hypertensive persons. Male and female of various age groups and different nationalities were considered for the study. The project was sponsored by a pharmaceutical firm Merck, Sharp and Dome (MSD). Biochemist (Medical Technologist) 1984-1988: Biochemist (Medical Technologist), Department of Nephro-Urology, Jinnah Postgraduate Medical Center (JPMC), Karachi (Pakistan). In these two positions I was responsible for performing clinical biochemistry, hematology, and serology tests for the diagnosis of heath related problems. I was also responsible for the teaching and training of postgraduate medical research students and junior laboratory staff. While working as a Biochemist in the Department of Nephro-Urology at JPMC I also undertook the following two research projects related to chronic renal failure and nephrotic syndrome: 1) Serum lipids, their subfractions and hemoglobin A1 in patients with chronic renal failure (CRF). This project was undertaken in fulfillment for the requirements of degree of Master of Philosophy in Biochemistry. The goal of this project was to compare levels of lipids and lipid subfractions in CRF

patients and in healthy control subjects. In addition, urea derived carbamylated hemoglobin was determined in CRF patients and compared with the severity of the disease. 2) Serum proteins and lipid levels in patients with nephrotic syndrome (NS). NS is kidney disorder that can occur at any age but is more prevalent in children than in adults. This condition is marked by proteinurea and hypoproteinemia; edema, especially around the eyes, feet, and hands; and high cholesterol. Disease results in damage to the kidney's glomeruli, which gradually lose their ability to filter waste and excess water from the blood, and ultimately patients undergo CRF. The goal of this project was to find abnormalities in lipids and their subfractions in NS patients and to compare levels with the severity of the disease.
