MONROE, La. 鈥� The National Institutes of Health (NIH) has awarded University of Louisiana Monroe
professor Dr. Karen Briski a five-year $1.7 million grant that may one day lead to
a life-changing treatment of Type-1 diabetes.
This research project grant (R01) is the largest single grant awarded to a faculty
member in the history of 四色AV.
鈥淭he competition for federal research dollars is fierce, with award rates in the 10
to 30% range. R01 funding from NIH is one of the more competitive instruments, so
this award signals how well-respected scientists view the quality of Dr. Briski's
previous research and the importance of the discoveries anticipated from her laboratory's
work,鈥� said Dr. Eric Pani, 四色AV鈥檚 VP of Academic Affairs.聽
Briski鈥檚 research will focus on a completely novel way of protecting nerve cells from
injury due to hypoglycemia by investigating how estrogen can increase energy stored
in the brain.
Hypoglycemia is a recurring side effect of strict insulin therapy to stabilize blood
glucose (sugar) levels in Type-1 diabetes patients. It poses a significant risk for
nerve cell damage and neurological dysfunction.
Fear of hypoglycemia can deter diabetic patients from rigorous management of glucose,
which can result in overly-high blood sugar, or hyperglycemia. In the long-term, repeated
hyperglycemia can lead to blindness, skin infections, organ damage and nerve damage
in the feet and hands. 聽
Studies have shown that the stress and anxiety of maintaining proper glucose levels
can lower a patient鈥檚 quality of life. But Briski hopes to improve the quality of
life of these patients by reducing harmful effects of hypoglycemia.
鈥淒iabetic patients are found in every community. Hypoglycemia is an unavoidable aspect
of their daily lives. If our outcomes here can lead us on the road to developing a
therapeutic strategy whereby their brain is less vulnerable to injury and damage during
hypoglycemic episodes, then it is going to have a major benefit to their quality of
life,鈥� Briski said.
Briski鈥檚 studies suggest that estrogen plays a beneficial role in increasing the amount
of glycogen (stored glucose) in the brain and facilitating its release during episodes
of hypoglycemia.
Estrogen is best known as a major sex hormone in women but it is also present in males
at lower levels. However, it also has other uses in the body. Briski believes that
estrogen releases stored glucose in specific regions of the brain, so she plans to
target her research to these areas.聽
Briski credits this innovative approach to the 鈥渦nparalleled level of resolution鈥�
that the School of Pharmacy has brought to this field of research by being able to
dissect individual nerve cells and measure proteins produced by single populations
of these cells.聽聽
This level of 鈥渕icrodissection鈥� is accomplished through the use of state-of-the-art
laser catapult technology that 四色AV president Dr. Nick J. Bruno helped acquire several
years ago.
鈥淒r. Bruno was instrumental in procuring as part of my startup what is called the
Zeiss Laser Catapult Microdissection instrument as well as a confocal microscope.
Both are two state-of-the-art instruments and much of my scholarly and grantsmanship
success over the last couple years has been the use of these instruments,鈥� said Briski.聽
Over the next five years, Briski will be joined by four other 四色AV researchers, who
served as co-investigators on the grant: Dr. Paul Sylvester, Dr. Seetharama Jois,
Dr. Christopher Gissendanner, and Dr. Sami Nazzal.
About the National Institutes of Health (NIH)
Founded in 1887, the National Institutes of Health today is one of the world's foremost
medical research centers, and the Federal focal point for medical research in the
United States. The NIH, comprising 27 separate Institutes and Centers, is one of eight
health agencies of the Public Health Service which, in turn, is part of the U.S. Department
of Health and Human Services.
