Auditory Brainstem Implant Patients Needed For Research Study
A clinical research study of patients who have an auditory brainstem implant (ABI) is being conducted jointly by researchers at the Massachusetts Eye and Ear Infirmary (MEEI), Massachusetts Institute of Technology (MIT), and Harvard Medical School. We will use specialized hearing testing to better understand how your brain responds to stimulation from your ABI.  

Natural History Study of Plexiform Neurofibromas
 
This is a research study of the rate of growth of plexiform neurofibromas. The growth patterns of plexiform neurofibromas appear to be unpredictable, with the tumors often growing for periods of time and then remaining stable. The factors that influence neurofibroma growth are largely unknown.

The goals of this study is to closely monitor the growth of plexiform neurofibromas for a period of at least three years using magnetic resonance imaging (MRI). We will be analyzing the MRI data in a special way that allows us to precisely measure the volume of the neurofibroma. By repeating the assessment every six to 24 months, we hope to document the rate of change in size of the plexiform neurofibroma and to demonstrate that volume analysis of MRI data provides a reliable means of measuring neurofibroma growth. Finally, the study will bring together clinical and research resources that can later be used to test potential treatments of neurofibromas.

This is an international study funded by the U.S. Department of Defense NF Research Program. Eighteen medical centers worldwide are recruiting patients for this study, including Texas Childrenâs Hospital in Houston. For more information about the study and how to get involved contact:

Listed on this page are several researchers interested in obtaining tumor tissue from NF patients for laboratory studies. For these studies, the surgery must be performed for your medical care and there may be excess tissue available that can be donated for research studies. Please contact the researchers directly if you are interested. It is very important to arrange for this type of study well in advance of the surgery and to be aware that not all hospitals are able to comply with your request to send tissue for research.
 
NF1 Neurofibroma and Malignant Tumor Tissue Needed
 
Dr. Peggy Wallace and Dr. David Muir at the University of Florida have federal funding to continue their research of NF1 tumors. They are studying benign tumors (plexiform neurofibromas) and malignant tumors (often called neurofibrosarcoma, or MPNST). The goal of this work is to understand the changes that cause growth of these tumors to help develop better treatments. If you or a family member or friend is arranging surgery to remove any tumors for clinical reasons (preferably at least the size of an average marble) and would like to contribute extra surgical tissue to this research, please contact Dr. Wallace. She will discuss the research with you and help make arrangements to recover any extra tumor material (not needed by your physicians) if you wish to participate. It helps to make arrangements ahead of the surgery you schedule, as we need the tissue treated in a special way. A small amount of blood (one to three teaspoons) will also be needed, which can be obtained at the same time or another date. Dr. Wallace and Dr. Muir thank you very much for your help!

Neurofibromas Needed
 
Dr. Nancy Ratner at Cincinnati Childrenâs Hospital Medical Center requires neurofibromas from NF1 patients for an ongoing study of tumor growth factors, growth factor receptors and signaling pathways in neurofibroma cells. To be enrolled in this study, tumors must be removed for medical reasons. If you are interested in your tumor tissue being used for this study, AFTER you are scheduled for surgery, please have your physician or his/her nurse contact Dr. Ratner at least 24 hours prior to removal of tumors for instructions. Please do not contact Dr. Ratner directly; the contact must come from the doctor so that tumor is handled correctly. The study requires sterile tumor tissue covered by and shipped in tissue culture medium, on wet ice. Plexiform or cutaneous neurofibromas can be used. Some patient information (age, sex, criteria used to make the diagnosis of NF1) is required. Dr. Ratner will pay shipping costs but cannot pay the cost of surgery.

Midkine as a Diagnostic Marker for Neurofibromatosis
 
We are conducting a research study that is designed to explore a diagnostic blood test for NF1 and NF2. The protein midkine is often found in the serum of individuals with neurofibromatosis at high levels. If this result can be confirmed in a large number of individuals, midkine could become an independent diagnostic marker for NF1 and for NF2. In order to test this idea, we are recruiting individuals diagnosed with NF1 or NF2 to participate in our study.

If you have NF1 or NF2 and are interested in participating, or have any questions, please contact the investigator in charge of this study (contact information below). After this initial contact, participants will need to visit their regular physician to donate 10 ml of blood (about two teaspoons) and answer a brief questionnaire regarding your symptoms.

If you are interested in participating, or have any questions, please contact the investigator in charge of this study.

Mitochondrial Polymorphism and Number of Neurofibromas in NF1
 
We are conducting a research study that is designed to explore the reason why some individuals with NF1 develop a large number of neurofibromas, whereas others may develop a smaller number. We believe that there may be genes aside from the NF gene itself that help to determine the overall number of neurofibromas a person with NF will develop. In order to test this idea, we are recruiting individuals with NF to participate in our study. Specifically, we are looking for individuals who fit in any of the following categories:

Age Number of Neurofibromas
18-20 years old - fewer than five or more than 30
20-30 years old - fewer than 10 or more than 100
30-40 years old - fewer than 20 or more than 200
older than 40 years - fewer than 50 or more than 500

Participation in the study will have a physical examination and donate 20 ml (about four teaspoons) of blood. If you fit into any of the above categories and are interested in participating, or have any questions, please contact the investigator in charge of this study.

Seeking Doctors with NF1 Cases With Large Gene Deletions
 
Researchers at the University of Milan are interested in NF1 patients with a complex phenotype who are thought to bear large deletions involving NF1 gene. Their aim is to define by FISH analysis on chromosome spreads the sequences involved in the deletions. In particular, they are studying NF1 patients with dysmorphisms, mental retardation of any degree and other associated anomalies involving different systems. If you have any cases of this nature, please contact:

Call For Schwannomatosis Samples
 
Array-CGH (comparative genomic hybridization) is suitable for comprehensive and high-resolution profiling of DNA-copy-number. It allows simultaneous detection of heterozygous/homozygous deletions and/or amplifications occurring in constitutional or tumor DNA (Bruder et al., Hum Molec Genet, 2001. 10:271-282). A high-resolution array fully covering the entire 22q has recently been constructed and successfully applied in the analysis of tumor-derived and constitutional DNA.

The aim of this project is to characterize the frequency and location of deletions, which occur outside the NF2 locus on chromosome 22. This research task aims to characterize additional 22q-located gene(s), which may contribute to the development of schwannomatosis and the severe phenotype of neurofibromatosis type 2.

We would like to obtain blood-derived DNA or a blood sample from patients affected with schwannomatosis; i.e., patients with two or more pathologically verified schwannomas, plus lack of radiographic evidence of vestibular nerve tumor at age >18 years. These can be familial or sporadic cases. We need >25 microgram of high-molecular-weight DNA from peripheral blood. Alternatively, we would like to obtain 30 ml of peripheral blood (in EDTA tubes) transported to us via overnight courier service. Basic clinical details of the studied patients are also necessary.

Our project receives support from the U.S. Army Neurofibromatosis Research Program, the Swedish Cancer Society, the Uppsala University and the Swedish Research Council. The use of material derived from human subjects has been approved by the Uppsala University Research Ethics Committee (Institutional Review Board).

TEXAS NF FOUNDATION RESEARCH UPDATE
 
Texas NF Foundation has contributed more than $550,000 directly to research efforts to find a treatment for NF with the help of the Denise Terrill Charity Classics.

The Foundation has been funding research conducted by Dr. Hiroshi Maruta at the Ludwig Institute for Cancer Research in Melbourne, Australia. He has discovered that the NF pathways in the body are shared by 70% of all cancers, and have developed a substance (FK228) that has been able to block NF tumor growth in genetically engineered mice.

This research is very exciting. Last year, we were able to contribute $95,000 to Dr. Marutaâs research efforts. This year, our goal is to raise $125,000 for Dr. Maruta.

Dr. Marutaâs research has just been published in the April issue of the Cancer, Biology and Therapy journal. For more information on the article go to: http://www.LandesBioscience.com

Title: Signal Therapy of NF1-deficient Tumor Xenograft in Mice by the Anti-PAK1 Drug FK228

Author(s):
Yumiko Hirokawa, Hidenori Nakajima, C. Oliver Hanemann, Andreas Kurtz, Silke Frahm, Victor Mautner, Hiroshi Maruta

PAK1, a Rac/CDC42-dependent Ser/Thr kinase, is required for the malignant growth of RAS transformants, as well as both NF1-deficient and NF2-deficient cancer cells. FK228, a histone deacetylase (HDAC) inhibitor, suppresses the growth of more than 70% of human cancers in vivo, including RAS transformants, breast cancers and prostate cancers by activating a set of genes, including the tumor suppressors gelsolin and p21/WAF1, that block up-stream and down-stream of PAK1, respectively. Here we demonstrate that (i) the anti-PAK1 drug FK228 (0.1 nM) completely blocks the growth of both NF1-deficient and NF2-deficent cancer cells in vitro, and that (ii) FK228 (2.5 mg/kg, i.p., twice a week) causes the complete regression of an NF1-deficient human malignant peripheral nerve sheath tumor (MPNST) xenograft in nude mice. This is the very first case where a chemical drug in clinical trials for cancers has ever worked so effectively on neurofibromatosis (experimental neurofibromas) in vivo.
