Randi and Paul Hagerman
Randi Jenssen Hagerman, MD is a developmental
and behavioral pediatrician and the Tsakopoulos-Vismara
professor of Pediatrics at the University of California
at Davis, Medical Center. Dr. Hagerman is the Director
of the MIND Institute (Medical Investigation of Neurodevelopment
Disorders) at UC Davis and has become internationally
known as a Fragile X clinician and researcher. As
the Director of the MIND Institute, Dr. Hagerman is
at the helm of one of the country's primary clinics
for evaluation, diagnosis and treatment of a wide
spectrum of neurodevelopment disorders including Autism,
Asperger's and Fragile X. Her husband, Paul, joined
UC Davis in the Department of Biological Chemistry
and as an associate researcher with the M.I.N.D. Institute.
A founding CFXF Scientific Advisor, Dr. Hagerman has
been quoted previously in this newsletter as having
told the U.S. Congress that "Fragile X is a 'research
portal' for other brain disorders. It is the leading-edge
candidate for a breakthrough in understanding many
other diseases, especially autism". This fact of Fragile
X as a 'portal' is most attractive to researchers
such as Dr. Hagerman who recognize its potential to
unlock the mystery of disorders that affect millions
of people around the world. Dr. Hagerman has spent
over 20 years on Fragile clinical work and research,
particularly in molecular clinical correlation and
treatment endeavors. Dr. Hagerman is the chairman
of the Scientific and Clinical Advisory Committee
of the National Fragile X Foundation and is a scientific
reviewer for the FRAXA Foundation. The third edition
of Dr. Hagerman's book, Fragile X Syndrome: Diagnosis,
Treatment and Research, will be published in 2002
by the Johns Hopkins University Press.
Brenda Finucane, M.S., C.G.C.
Brenda is a genetic counselor and
the Director of Genetic Services at the Elwyn
Training and Research Institute in Media, Pennsylvania.
Elwyn is a private, nonprofit corporation which
provides a variety of residential and day services
for people with developmental disabilities in
the U.S. and overseas.
Since 1985, Ms. Finucane has been providing genetic
diagnostic and counseling services within an educational
setting, allowing her the unique opportunity to
research and apply practical knowledge about fragile
X syndrome. She has been directly responsible
for the diagnosis of over 80 children and adults
with fragile X syndrome within the Elwyn System
alone. She is an active participant along with
educators, psychologists and other school personnel
in team meetings and behavioral planning for both
day and residential students. Through Elwyn's
Technical Assistance for Schools program, she
has also had many opportunities to visit schools
throughout the U.S. to provide staff training
and to assist in the development of education
and behavior pans for students with fragile X
syndrome. She states, "I feel strongly that
the benefits of a fragile X diagnosis should extend
beyond the valuable genetic information provided
to families. There is a rich body of research
on behavior and learning styles in these individuals
which has immediate applicability at school and
in the home. I strongly support the work of CFXF
in fostering research into the molecular underpinnings
of fragile X syndrome, and in its interest in
discovering a cure at the biochemical level. Until
that dream is realized however, there is still
much we can do to ameliorate symptoms in children
and adults with this condition."
In addition to her work with CFXF, Ms. Finucane is
a member of the Scientific and Clinical Advisory Committee
of The National Fragile X Foundation, and she serves
as a contact for newly-diagnosed families within the
mid-Atlantic region. Her work in genetics extends
to many other syndromal causes of developmental disabilities,
and she is widely published. Recent publications include
an updated edition of Fragile X Syndrome: A Handbook
for Families and Professionals (in press) which is
distributed by The National Fragile X Foundation.
In 2000, she co-authored the book, Genetics and Mental
Retardation Syndromes: A New Look at Behavior and
Interventions (Brookes Publishing Company) with UCLA
psychologists Elisabeth Dykens and Robert Hodapp
Dr.
Gideon Dreyfuss
Dr. Gideon Dreyfuss, Isaac Norris Professor
of Biochemistry and Biophysics, Howard Hughes Medical
Institute Investigator, University of Pennsylvania
School of Medicine.
Dr. Dreyfuss received his Ph.D. degree in biological
chemistry from Harvard University in 1978 and was
a Helen Hay Whitney post-doctoral fellow at the Massachusetts
Institute of Technology. Prior to his present appointment,
he was Professor and Established Investigator of the
American Heart Association at Northwestern University.
Dr. Dreyfuss is chiefly interested in the transport
of RNAs and proteins between the nucleus and cytoplasm
and in the molecular functions of SMN, the protein
responsible for the neurodegenerative disease spinal
muscular atrophy.
The research efforts of the Dreyfuss laboratory are
presently focused on four interrelated topics:
* The transport of proteins and RNAs between the
nucleus and the cytoplasm.
* The molecular function of SMN (Survival of Motor
Neurons), the protein product of the Spinal Muscular
Atrophy (SMA) disease gene
* The structure and function of the hnRNP proteins,
with particular focus on the role of these proteins
in the formation and function of mRNA
* Novel phage display methods for identification
of interacting proteins.
Two of Dr. Dreyfuss' more recent publications include:
Nakielny, S. and G. Dreyfuss (1999) Transport of proteins
and RNAs in and out of the nucleus. Cell 99:677-690
and Kataoka, N., J. Yong, V.N. Kim, F. Velazquez,
R.A. Perkison, F. Wang and G. Dreyfuss (2000) Pre-mRNA
splicing imprints mRNA in the nucleus with a novel
RNA-binding protein that persists in the cytoplasm.
Mol. Cell 6:673-682
Dr.
Assam El-Osta
The Scientific Advisory Board of the
Conquer Fragile X Foundation counts among its ranks
some of the most well respected leaders in the fragile
X research world. Not only have they dedicated their
professional careers to the study of fragile X and
other such disorders, but they continue to be so generous,
providing their experience and guidance to our cause.
Each issue of the CFXF newsletter highlights one of
these remarkable scientists and now we proudly introduce
you to our newest member, Dr. Assam El-Osta.Recently,
Dr. Assam El-Osta, of the Peter MacCallum Cancer Institute
joined the Conquer Fragile X Foundation's Board of
Scientific Advisors and became a CFXF project grantee.
Along with our other Scientific Advisors, Dr. El-Osta
will provide the Foundation with scientific guidance
and share his experience. Dr. El-Osta's project, "Profiling
Chromatin-Dissecting the regulatory binding pattern
of Fragile X chromosome in vivo." was recently
funded by CFXF.
At present, Dr. El-Osta is a Senior Research Fellow
at the Peter MacCallum Cancer Institute at Melbourne,
a facility he joined in 1997. After receiving his
Ph.D. from the University of Melbourne, he was immediately
awarded the highly prestigious and nationally competitive
Anti-Cancer Council of Victoria, Postdoctoral Research
Fellowship and worked as a Research Fellow at the
Peter MacCallum Cancer Institute where he continues
his work in transcriptional gene silencing.
In 1999 Dr. El-Osta was invited by the world renowned
chromatin biologist, Dr. Alan P. Wolffe to join him
and his team at the Laboratory of Molecular Embryology,
National Institutes of Health, U.S.A. to examine in
greater detail the repression mechanisms of human
MDR1 gene in cancer. A mentor and a good friend, Alan
Wolffe nurtured El-Osta's research objectives and
together they identified the transcriptional repressor
complexes associated with the therapeutically relevant
multidrug resistance (MDR1) gene. Understanding the
mechanism of transcriptional regulation is crucial
if we are to offer therapeutic intervention. This
work was published recently in prominent molecular
and cellular biology publications.
We are delighted to have Dr. El-Osta serve as a scientific
advisor and to join our distinguished fragile X researchers.
Welcome, Dr. El-Osta.
Dr. Karen Usdin
Dr. Karen Usdin received
her Ph.D. in 1986 from the University of Cape Town,
South Africa. After doing Post-Doctoral work on gene
regulation in bacteria and a family of endogenous
retrovirus-like elements in mammals, she turned her
attention to the Repeat Expansion diseases, a group
of genetic disorders that includes fragile X syndrome.
She is now a Senior Investigator in the Laboratory
of Molecular and Cellular Biology at the National
Institutes of Health, U. S. A. Her group is investigating
the mechanism responsible for the fragile X mutation.
They are also interested in the molecular basis of
the premature ovarian failure seen in some female
carriers of “premutation” alleles and
the tremor and ataxia seen in some male carriers.
In addition, they are trying to understand the molecular
events that lead to the transcriptional silencing
of the FMR1 gene in people with fully mutated alleles.
Their work involves the analysis of DNA and RNA structures
formed by the fragile X gene as well as the proteins
that bind to them. Her group has also developed a
number of cell and animal models for studying different
aspects of fragile X syndrome. It is hoped that these
models may provide new insights into the normal and
pathological regulation of the FMR1 gene, and may
one day provide good systems for testing potential
treatments for this disorder.
