Margo Panush Cohen is an American physician and entrepreneur. She has been a Professor of Internal Medicine and Chief of Endocrinology and Metabolism at the Wayne State University School of Medicine and the University of Medicine and Dentistry of New Jersey. She is President and Chief Scientific Officer of Glycadia, and a founder of its subsidiary Exocell.
Cohen earned a BS from the University of Michigan and an MD from the University of Michigan Medical School. She held an internship at Sinai Hospital in Detroit, Michigan and a residency at Detroit's Henry Ford Hospital. She was then awarded fellowships from the Public Health Service and the National Institutes of Health and pursued doctoral studies in biochemistry at Wayne State University. Moving with her family to Argentina, she completed her doctoral program at the University of Buenos Aires. [1] [2]
Returning from Argentina, Cohen joined the faculty of Wayne State University School of Medicine as Assistant Professor of Medicine, becoming Full Professor and head of Endocrinology and Metabolism at the Medical Center's Detroit Receiving Hospital. [1] In 1982 she became Professor of Medicine and Head of the Division of Endocrinology and Metabolism at the University of Medicine and Dentistry of New Jersey. She received a Fulbright Scholarship in 1986 for a sabbatical in Israel at the Beilinson Hospital/University of Tel Aviv. [1]
Cohen founded Exocell in 1988 to develop diabetes-related diagnostic products, and subsequently established Glycadia to develop therapeutic products. The company received initial financing from venture funds and the Commonwealth of Pennsylvania. Its first FDA-approved diagnostic product was Albuwell, a test that detects diabetic kidney disease, followed by other diagnostic products approved by the U.S. Food and Drug Administration (FDA) to monitor diabetes management and complications. [1] [3] She holds twelve patents in the field of diabetes treatment. [4] She continues to be the President and Chief Scientific Officer of Glycadia, . [5]
Cohen has been editor-in chief- of the Journal Endocrinology and served on study sections of the National Institutes of Health. She was twice appointed Chairman of the Board of Scientific Counselors for the National Institute of Dental Research at the National Institutes of Health. [6] [7] She was elected a member of the American Society for Clinical Investigation in 1982 and is currently[ when? ] an emeritus member of the society. [8]
Cohen has contributed to several areas in endocrine and diabetes research. While in graduate school, she uncovered the mechanism by which the anti-convulsant aminoglutethemide interferes with the production of adrenal steroids, leading to clinical use of the drug in hormone-dependent cancers. [9] [10] In Argentina she studied the effects of diabetes, insulin and pituitary hormones on protein synthesis and vascular metabolism. [11] [12] As a visiting scientist in England, she examined effects of diabetes on basement membranes. [13] In Israel, Cohen discovered the increased prevalence of diabetes in young Ethiopian immigrants and linked it to radical changes in dietary habits. [14] [15] She has also researched immune factors diabetes [16] and the cause of kidney, eye and vascular complications tied to diabetes, uncovering the role of increased nonenzymatic glycation in their genesis and identifying abnormalities in the production of matrix components and in signaling pathways inhibition. [17] [18] [19] [20] [21] [22]
Cohen has authored and edited numerous books in the areas of diabetes, endocrinology and metabolism. These include:
Cohen married her college boyfriend, Perry M. Cohen, an investment banker, and she is the mother of three sons:. [1] [23] [24] [25]
The adrenal glands are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla. The adrenal cortex itself is divided into three main zones: the zona glomerulosa, the zona fasciculata and the zona reticularis.
The endocrine system is a messenger system in an organism comprising feedback loops of hormones that are released by internal glands directly into the circulatory system and that target and regulate distant organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems.
Hyperglycemia is a condition in which an excessive amount of glucose circulates in the blood plasma. This is generally a blood sugar level higher than 11.1 mmol/L (200 mg/dL), but symptoms may not start to become noticeable until even higher values such as 13.9–16.7 mmol/L (~250–300 mg/dL). A subject with a consistent fasting blood glucose range between ~5.6 and ~7 mmol/L is considered slightly hyperglycemic, and above 7 mmol/L is generally held to have diabetes. For diabetics, glucose levels that are considered to be too hyperglycemic can vary from person to person, mainly due to the person's renal threshold of glucose and overall glucose tolerance. On average, however, chronic levels above 10–12 mmol/L (180–216 mg/dL) can produce noticeable organ damage over time.
Type 2 diabetes (T2D), formerly known as adult-onset diabetes, is a form of diabetes mellitus that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. Common symptoms include increased thirst, frequent urination, fatigue and unexplained weight loss. Symptoms may also include increased hunger, having a sensation of pins and needles, and sores (wounds) that do not heal. Often symptoms come on slowly. Long-term complications from high blood sugar include heart disease, strokes, diabetic retinopathy which can result in blindness, kidney failure, and poor blood flow in the limbs which may lead to amputations. The sudden onset of hyperosmolar hyperglycemic state may occur; however, ketoacidosis is uncommon.
Cortisol is a steroid hormone, in the glucocorticoid class of hormones and a stress hormone. When used as a medication, it is known as hydrocortisone.
Endocrine glands are ductless glands of the endocrine system that secrete their products, hormones, directly into the blood. The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testicles, thyroid gland, parathyroid gland, hypothalamus and adrenal glands. The hypothalamus and pituitary glands are neuroendocrine organs.
Advanced glycation end products (AGEs) are proteins or lipids that become glycated as a result of exposure to sugars. They are a bio-marker implicated in aging and the development, or worsening, of many degenerative diseases, such as diabetes, atherosclerosis, chronic kidney disease, and Alzheimer's disease.
Diabetic nephropathy, also known as diabetic kidney disease, is the chronic loss of kidney function occurring in those with diabetes mellitus. Diabetic nephropathy is the leading causes of chronic kidney disease (CKD) and end-stage renal disease (ESRD) globally. The triad of protein leaking into the urine, rising blood pressure with hypertension and then falling renal function is common to many forms of CKD. Protein loss in the urine due to damage of the glomeruli may become massive, and cause a low serum albumin with resulting generalized body swelling (edema) so called nephrotic syndrome. Likewise, the estimated glomerular filtration rate (eGFR) may progressively fall from a normal of over 90 ml/min/1.73m2 to less than 15, at which point the patient is said to have end-stage renal disease. It usually is slowly progressive over years.
Glibenclamide, also known as glyburide, is an antidiabetic medication used to treat type 2 diabetes. It is recommended that it be taken together with diet and exercise. It may be used with other antidiabetic medication. It is not recommended for use by itself in type 1 diabetes. It is taken by mouth.
11β-Hydroxysteroid dehydrogenase enzymes catalyze the conversion of inert 11 keto-products (cortisone) to active cortisol, or vice versa, thus regulating the access of glucocorticoids to the steroid receptors.
Type 1 diabetes (T1D), formerly known as juvenile diabetes, is an autoimmune disease that originates when cells that make insulin are destroyed by the immune system. Insulin is a hormone required for the cells to use blood sugar for energy and it helps regulate glucose levels in the bloodstream. Before treatment this results in high blood sugar levels in the body. The common symptoms of this elevated blood sugar are frequent urination, increased thirst, increased hunger, weight loss, and other serious complications. Additional symptoms may include blurry vision, tiredness, and slow wound healing. Symptoms typically develop over a short period of time, often a matter of weeks if not months.
Fructosamines are compounds that result from glycation reactions between a sugar and a primary amine, followed by isomerization via the Amadori rearrangement. Biologically, fructosamines are recognized by fructosamine-3-kinase, which may trigger the degradation of advanced glycation end-products. Fructosamine can also refer to the specific compound 1-amino-1-deoxy-D-fructose (isoglucosamine), first synthesized by Nobel laureate Hermann Emil Fischer in 1886.
Vildagliptin, sold under the brand name Galvus and others, is an oral anti-hyperglycemic agent of the dipeptidyl peptidase-4 (DPP-4) inhibitor class of drugs. Vildagliptin inhibits the inactivation of GLP-1 and GIP by DPP-4, allowing GLP-1 and GIP to potentiate the secretion of insulin in the beta cells and suppress glucagon release by the alpha cells of the islets of Langerhans in the pancreas.
Endocrine diseases are disorders of the endocrine system. The branch of medicine associated with endocrine disorders is known as endocrinology.
Dapagliflozin, sold under the brand names Farxiga (US) and Forxiga (EU) among others, is a medication used to treat type 2 diabetes. It is also used to treat adults with heart failure and chronic kidney disease. It reversibly inhibits sodium-glucose co-transporter 2 (SGLT2) in the renal proximal convoluted tubule to reduce glucose reabsorption and increase urinary glucose excretion.
3-Deoxyglucosone (3DG) is a sugar that is notable because it is a marker for diabetes. 3DG reacts with protein to form advanced glycation end-products (AGEs), which contribute to diseases such as the vascular complications of diabetes, atherosclerosis, hypertension, Alzheimer's disease, inflammation, and aging.
George Widmer Thorn was an American physician whose contributions led to new treatments of kidney diseases and adrenal gland disorders, most notably Addison's disease. Thorn was Chief of Medicine at Boston's Peter Bent Brigham Hospital, presently known as Brigham and Women's Hospital. Thorn pioneered the use of cortisone for treating Addison's disease, and devised an early test for this disease, now known as the Thorn test. His research of cortisone and ACTH led to new treatments of other diseases such as hypertension, rheumatoid arthritis and diabetes.
Leonid Poretsky is a Russian-born American endocrinologist. His research interests include mechanisms of insulin action in the ovary, endocrinological aspects of AIDS, and clinical outcomes in diabetes. He has authored over 150 publications and has served on the National Institutes of Health's review committees and on the editorial boards of the Journal of Clinical Endocrinology and Metabolism and other endocrine journals.
Diabetes mellitus, often known simply as diabetes, is a group of common endocrine diseases characterized by sustained high blood sugar levels. Diabetes is due to either the pancreas not producing enough insulin, or the cells of the body becoming unresponsive to the hormone's effects. Classic symptoms include thirst, polyuria, weight loss, and blurred vision. If left untreated, the disease can lead to various health complications, including disorders of the cardiovascular system, eye, kidney, and nerves. Untreated or poorly treated diabetes accounts for approximately 1.5 million deaths every year.
