Professor Roger Guillemin, M.D., Ph.D.

Nobel Laureate
Immediate past President of the
Salk Institute of La Jolla, CA.
2010 Gentle Giant Award Recipient

Roger Guillemin, immediate past president of the Salk Institute and distinguished professor, was awarded the Nobel Prize in 1977 for discoveries that laid the foundation for brain hormone research. His work brought to light an entire new class of substances shown to be important for the regulation of growth, development, reproduction and responses to stress. The impact of his studies has been profound for a variety of diseases and disorders, including thyroid diseases, problems of infertility, diabetes, and several types of tumors.

One of these hormones, called growth-hormone releasing factor, is used to treat growth deficiencies in children; another, called somatostatin, is used to control tumors of the pituitary gland. Dr. Guillemin was also among the first to isolate endorphins, brain molecules known to act as natural opiates. Following the isolation of endorphins, his work with cellular growth factors (CGFs), in addition to inhibins and activins, led to the recognition of multiple physiological functions and developmental mechanisms.

Since his retirement from the active pursuit of science in 1989, Dr. Guillemin has shifted his long-standing expertise with computers from science to art.

Scott Hamilton

Olympic Gold Medalist, Figure Skating
2008 Award Recipient

On the second night of the 2008 December in the Desert Conference at the Rancho Las Palmas Resort & Spa, in Rancho Mirage, CA, the PNA presented its Gentle Giant Award to Mr. Scott Hamilton. Scott Hamilton is a world class athlete but he’s also a survivor of cancer and pituitary disease. Hamilton was diagnosed with testicular cancer in 1997, and learned he had a benign pituitary brain tumor (a craniopharyngioma) in November of 2004.

George P. Chrousos, M.D.

Professor and Chairman
Athens University Medical School
Children’s Hospital Aghia
2006 Award Recipient

On the second night of the 2006 December in the Desert Conference, the PNA presented its Gentle Giant Award to Dr. George Chrousos. Dr. Chrousos is a professor at the University of Athens and a leading expert on Cushing’s disease and psychiatric disorders caused by hormonal imbalances. He is the former chief of Pediatric Endocrinology at the National Institutes of Health.

The keynote speaker for the ceremony was Nobel Laureate Dr. Roger Guillemin, who talked about the history of acromegaly. Guillemin, a distinguished professor at the Salk Institute for Biological Studies in San Diego, California, won the Nobel Prize in 1977 for discoveries that laid the foundation for brain hormone research. His work brought to light an entirely new class of substances shown to be important for the regulation of growth, development, reproduction and responses to stress.

We are proud to count both Drs. Chrousos and Guillemin as members and supporters of the PNA.

George P. Chrousos is Professor and Chairman of Pediatrics at the Athens University Medical School. He has focused his research on the hypothalamicpituitary- adrenal (HPA) axis and has extensively studied the neuroendocrine alterations associated with mood disorders, sleep, pain perception, and immune function. His laboratory is recognized worldwide for its work on the glucocorticoid signaling system, diseases of the HPA axis, such as Cushing’s syndrome, and the physiologic and molecular mechanisms of stress.

Dr. Chrousos has contributed immensely to the biomedical literature and his work has provided new insights into a variety of chronic complex disorders. He has written over 1000 scientific papers and his work has been cited in about 35,000 other scientific articles, an irrefutable testimony to the importance and influence of his research. He is one of the most cited physician scientists in the world (ISI highly cited). His work has educated a broad community of physicians and scientists around the world. As a mentor, he has helped to develop the careers of many young physicians and scientists, several of whom are now professors and chairpersons in Europe, the United States, Australia and Latin America. An outstanding teacher, he has had a number of visiting professorships and given prestigious lectures throughout the world.

Dr. Chrousos has received numerous national and international awards for his work, including election to membership in the prestigious American Society of Clinical Investigation and the Association of American Physicians. He was recently inducted as a master of both the American College of Endocrinology and the American College of Physicians.

“Dr. George Chrousos has served as a leader and role model of Physician-Scientists in the field of pituitary medicine. His investigations have been carried out with a precise scientific approach, but always based on clinically-relevant questions. His interest in the interactions between the brain and the hormonal milieu has led him on a focused journey through the territory of the pituitary and its target, the adrenal, to clarify for patients and clinicians alike the importance of endocrinology in psychosocial medicine. For this body of work, his dedication and support of patients throughout the world, the PNA owes him a debt of gratitude.”
– Dr. Sylvia Asa

“I have known George for almost 20 years and there is no doubt that he is one of the premier researchers all time in the field of pediatric endocrinology. During his tenure at the NIH, he brought adrenal gland research to a new level.”
“I have to thank George for two things in particular. First, when I was at UCLA, he interviewed for our vacant Division Chief position, but, for whatever reasons, did not take the position. That was good news for me because I got the position. I am forever indebted. Second, one of my recent fellowship graduates, Dr. Maria Karantza, a Greek national, recently returned home to Athens and took a position with George. Maria was one of the best fellows I ever had and I have entrusted George with the further advancement of her career. I know that she is in great hands.”
– Dr. Mitchell Geffner

“Few Physician-Scientists have come close to the term. Dr. Chrosous embodies the descriptor better than anyone else I know. For decades Dr. Chrosous has made his mark by leading a world-class research team. However, what has set him apart was a constant eye for the clinically relevant. Always focused, introspective but with utmost humility, he has provided us with an outstanding role model.”
– Dr. Shereen Ezzat

“Chrousos in ancient as well as modern Greek, means gold. George Chrousos, our gold standard in endocrinology!”
– Dr. Roger Guillemin

“If there is such a category, Dr. Chrousos has earned the designation of both a ‘patient’s doctor’ as well as a ‘doctor’s doctor’! His devotion to the plight of children and adult patients with pituitary/hormonal disorders is by now legendary, world-wide! What is only known in the medical community, is that his devotion to the healing arts is such that he gathers the universal admiration and respect of other world class physicians. Having observed him in many countries, I know a good man when I see one. He is indeed a Gentle Giant.”
– Robert Knutzen

Charles B. Wilson, M.D.

University Of California, San Francisco
2002 Award Recipient

UCSF Professor Emeritus Charlie Wilson was honored on Saturday February 2nd 2002, in recognition of his outstanding contributions and dedication to the field of pituitary/endocrine medicine at the First Annual Gentle Giant Award Dinner.

The event was held at the Delancey Street Foundation, Town Hall, 600 Embarcadero, San Francisco.

Wilson is recognized worldwide for his surgical skills and commitment toward research and medical advancement. He has served on local, state and national committees and has served as a consultant in health care. Most notably, Wilson popularized and perfected the transsphenoidal approach to pituitary tumors by proving its effectiveness and safety. He has performed more than 3,300 transphenoidal surgeries for a pituitary tumor at UCSF Medical Center. His skills in surgery as well as in research have helped patients all over the world.

In 1968, Wilson was invited to UCSF to serve as professor and chairman of the neurosurgery division and to establish a laboratory for the study of brain tumors. By 1970, he had established the department of neurological surgery and the Brain Tumor Research Center (BTRC), a national cancer research center, which has been continuously funded by the National Institutes of Health since 1971. As director of the BTRC, Wilson realized an integrally related program of basic science and clinical research. The BTRC treats over 500 brain tumor patients each year, contributes extensively to basic and applied research in neuro-oncology, trains numerous neuro-oncologists and clinical and basic scientists in brain tumor research, and provides continuing education and consultation for private practitioners.

During the past few years, Wilson has redirected his primary focus to the organization and delivery of health care, in particular the challenges facing academic medicine in response to an environment of new market forces. He served as Senior Associate on Medical Affairs to the President of the University of California, in addition to his clinical practice at UCSF. In 1996, he obtained a Master’s degree in Health Administration.

Wilson resigned as chairman of the department of neurological surgery and director of the BTRC in April 1997 to pursue these interests. In July of that year, he was appointed Senior Research Fellow at the nonprofit independent research organization, Institute for the Future in Menlo Park and San Francisco. He now serves as its director, providing expertise in areas such as novel medical technologies, academic medical centers, the future of health care and the impact of genetics and genomics on health and health care. Wilson authored an article, “The Hospital of the Future,” which appeared in the September 2001 issue of UCSF Magazine.

Wilson earned his medical degree and received neurosurgical training at Tulane University, where he graduated first in his class in 1954.
