Dollars at WORK!

Wobbly Feet Foundation continues to beat national standards by donating 92% of every dollar towards our mission!

2016 was a most successful year with Wobbly Feet receiving over $95,000!! With these funds we have increased our contribution towards the A-T Children’s Project’s ( Global A-T Data Platform. This donation has been immediately put to work with the launch of this world-wide research study aimed at sequencing the individual genome of all children known to be diagnosed. The results of this study will give insight into any genetic variations that compensate for mutations in the A-T gene, possibility leading toward a drug treatment able to reduce the most devastating effect of A-T, the progressive neuro-degeneration.  140 A-T kids, including Connor, have already been sequenced and results are now being compiled. This study brings us new hope!

Additionally, we were able to continue funding of on-going research projects and provide grants to families of a child diagnosed with A-T to assist in payment of uninsured medical expenses aimed at improving their quality of life. Such grants include contribution towards a tank style wheelchair for a young man with A-T to continue to enjoy the rugged outdoor terrain of the Appalachian Trail near his home with his family and friends, a chair lift to help a young man with A-T transfer from the 1st to the 2nd floor of his family home where his bedroom is, assist a family to redesign their home pool for accessibility so their 2 wheel-chair bound sons may receive at-home water therapy and for a single mom whose young daughter with A-T.  & seizures could pay down the co-pays of the extensive medical bills pilling-up due to numerous hospital stays.

Funded research projects

On-going since 2015: The A-T Children’s Project launches the Global A-T Family Data Platform and Genome Sequencing Project. A patient driven effort lead by Anthony Philippakis, MD, PhD at the Broad Institute at Harvard and MIT, this platform is compiling clinical and genomic information in order to be shared and be accessed by scientists and researchers worldwide. 

  • 2017 update: Over 199 people with A-T have registered on the platform with 140 children with A-T contributing saliva samples for DNA sequencing. The platform is now available in 6 languages and is approved in 6 countries. Data is being established and will be available for researchers by October 2017

2017. Therapeutic Strategies for Ataxia Telangiectasia Lung Disease. Primary researcher: Dr. JoAnn M. Sekiguchi, PhD, University of Michigan. Grant period 1/1/2017-12/31/2018. A-T Children’s Project funded with support from Wobbly Feet.

Project description: to determine if anti-inflammatory compounds can reduce lung damage in a mouse model of A-T. About 25 percent of people with A-T develop lung disease. Problems with swallowing and aspiration, as well as weakened immune systems, lead to chronic lung disease. In addition, an inability to repair lung damage, premature aging, oxidative stress, and inflammation may contribute to the development of lung disease in A-T.

Dr. Sekiguchi and her laboratory will aim to learn if a certain type of immune cell, called a neutrophil, contributes to the over-active inflammatory response that occurs when the lungs of A-T mice are damaged. In hopes of finding a breakthrough approach to preventing lung damage in people with A-T, Dr. Sekiguchi’s team will test whether two compounds that target neutrophil-driven inflammation can reduce lung damage in A-T mice.

2017. Enabling Drug Screening for Ataxia TelangiectasiaPrimary researcher: Edward C. Gilmore, MD, PhD, Case Western Reserve University. Grant period 3/1/2017-2/28/2018. A-T Children’s Project funded with support from Wobbly Feet.

Project Description: Many drugs now taken by millions of people were discovered by high-throughput drug screening, a process in which scientists use robotics, data processing and control software, liquid handling devices and sensitive detectors to quickly perform millions of chemical tests until they find compounds that correct a biomolecular pathway that scientists believe is relevant to a disease. Now, the laboratory of Ed Gilmore, MD, PhD will begin this approach to ataxia-telangiectasia (A-T) and to discover drugs that treat the disease’s neurological problems. Based at Case Western Reserve University in Ohio, Dr. Gilmore believes that when the A-T protein is missing, a certain type of naturally occurring DNA damage, called double-strand breaks, isn’t repaired properly, ultimately leading to the brain cell death and neurological problems faced by children with A-T. His team will therefore focus on isolating brain cells from mice that have been engineered to have A-T and then identifying compounds that prevent double-strand breaks in those cells.

Once a promising compound(s) is identified, the A-T Children’s Project will quickly pursue the many subsequent steps required in drug discovery and development to advance effective and safe drugs that will slow or prevent the brutal neurological decline faced by patients. In this situation, Wobbly Feet intends to provide additional funding support.

2015. Defined A-T iPSC lines with genetic diversityPrimary researcher: Ronald Hart, PhD, Rutgers University. A-T Children’s Project funded with support from Wobbly Feet.

Project description: Ronald Hart, PhD and his lab will create induced pluripotent stem cells (iPSCs) using blood samples taken from kids with A-T. Disease-specific iPSCs are often called “disease in a dish” models, because they allow scientists to study a disease using cells in culture, outside of a human or animal body. Especially exciting, with the right stimulation, it may be possible to turn the iPSCs into brain cells, providing a way for neuroscientists to learn more about how A-T affects the brain. In addition, iPSCs can be used to screen chemical compounds for potential new drugs.

Update: Dr. Hart’s lab has established methods to test ATM function in iPSC lines to use as quality control when lines are distributed and is undergoing continued testing to reprogram A-T iPSC lines from existing blood samples.

2014. Metabolic Sensing and Stress Response Deficit in Ataxia TelangiectasiaPrimary researcher: Dr. Michael Kastan of Duke Cancer Institute. A-T Children’s Project funded with support from Wobbly Feet.

Project description: Scientists led by Michael Kastan, MD, PhD, head of the Duke Cancer Institute in Durham, North Carolina, have discovered that cells taken from A-T children are abnormally sensitive when deprived of nutrients such as glucose, glutamine and oxygen. With a grant from the A-T Children’s Project, the team will now study metabolic stress pathways in A-T to determine if metabolic abnormalities are responsible for the brain deterioration and lung problems of A-T. The goal of this project, which is co-funded by the Wobbly Feet Foundation, is to identify proteins in these pathways that, when influenced by drugs, may alleviate many of the devastating symptoms of A-T.

  • 2017 update: Dr. Kastan’s research is continuing to make advancements through a grant from the Orphan Disease Center at University of Pennsylvania School of Medicine.
  • 2015 update: Due to study results so far confirming their theoryDr. Kastan and his team will continue their research to explore possible drug targets towards a clinical trail.

2013. Mitochondrial Reactive Oxygen Species and Dysfunction in Ataxia-Telangiectasia.  Primary researcher: Dr. Gerald Shadel, PhD. Yale University.

  • 2014 update: Dr Shadel and staff’s result are positive, confirming their theory. At the end of yr 1 (2013), CT Innovations (Venture Capital firm) awarded Dr. Shadel a 2 yr grant to pursue the analysis of Mitochondrial defects in induced pluripotent stem cells from A-T patients.
  • 2016 update: Study results suggest mitochondrial antioxidant therapy as a useful approach to treat A-T. Additional tests are being completed to confirm.

2011-2013. Linking Neuro-degeneration to Protein Turnover in Ataxia Telangiectasia. Primary researcher: Dr. Shyamal Desai, PhD. Louisiana State University. A-T Children’s Project funded with support from Wobbly Feet.

2011-2013. PCD mice as an Animal Model of Ataxia in A-T  Primary researcher: Dr. Kamran Khokakhah, PhD. Albert Einstein University. A-T Children’s Project funded with support from Wobbly Feet.
