Based on progress to date, Dr. Stanton was awarded a new grant in 2022 and 2023 to fund an additional year of this Scholar grant.
Rhabdomyosarcoma (RMS) is a highly aggressive and lethal pediatric cancer affecting children and adolescents and arises in the soft tissue and skeletal muscle of the extremities, head and neck, and reproductive organs. From the clinical perspective, although patient outcomes have improved in general, nevertheless survival rates for some RMS tumors remains at less than 30%. One particularly aggressive subtype is alveolar RMS which is driven by the occurrence of chromosomal translocations resulting in the generation of chimeric or fusion proteins between the PAX3 or PAX7 and the FOXO1 genes. These are known as fusion-positive RMS (FP-RMS) and are associated with reduced relapse-free survival and generally poorer outcomes. But researchers still have limited understanding of how the "fusion" gene itself is driving the tumor, and no subtype-specific therapies exist. Dr. Stanton aims to determine how the fusion gene works with a protein complex known as BAF, to alter the epigenetic state of the cell to keep them dividing and stop the cell from differentiating into mature muscle tissue. His team is exploring the mechanism of how the BAF complex regulates the epigenetic state and memory of the FP-RMS. Furthermore, using small-molecule drugs and genetic depletion strategies (CRISPR) they will determine if FP-RMS tumors are dependent on the BAF complex for survival. Finally, they are working to identify potential novel therapies for patients with aggressive and lethal FP-RMS, to improve their outcome.

The 2021 and 2022 portions of this grant is funded by and named for the Aiden's Army Fund. When he was 8 years old, Aiden Binkley was diagnosed with Stage IV rhabdomyosarcoma. He had a huge tumor in his pelvis and the cancer had metastasized to his lungs. But this bright, funny and courageous boy believed he got cancer so he could grow up to find a cure for it. Aiden’s story has inspired so many people and his vision to cure cancer is being carried on by Aiden’s Army through the funding of research. They will march until there is a cure!

The 2020 and 2023 portions of this grant is funded by and named for by Berry Strong, a St. Baldrick’s Hero Fund, established in honor of Caroline Berry. Diagnosed with alveolar rhabdomyosarcoma when she was 14, Caroline endured a two-year battle with courage and determination. Throughout treatments of radiation and chemotherapy and undergoing six surgeries, Caroline was a beacon of hope, unselfishly raising awareness and funding for research so no child would have to endure what she did. After a brief remission, scans revealed Caroline had relapsed and she passed away on Thanksgiving in 2018. Caroline is remembered as a bright light, creative, intelligent, funny and feisty who was always eager to share a smile with others. She continues to be an inspiration through the Berry Strong Hero Fund which will continue her legacy and her passion to raise awareness and fund the most promising childhood cancer research.

Based on progress to date, Dr. Ou was awarded a new grant in 2022 and 2023 to fund an additional year of this Scholar grant. Due to the tumor and treatment damaging the developing brain, 60-80% of pediatric brain tumor survivors experience long-term neurocognitive impairment. There are two possible paths to improve outcomes: intervene the adverse brain development after treatment, or further optimize radiotherapy dose distribution in the brain before treatment. For the former, the question is to find at-risk patients to intervene after treatment. For the latter, the question is to find target brain regions, where changing radiation doses can potentially change outcomes. Both questions have been studied on the population-level, not on the individual level. This project aims to push our knowledge in these two fronts to the individual level. Dr. Ou is using data from 3 just finished clinical trials to find target patients and find target brain regions for radiation dose optimization. Compared to studies that consider one risk factor a time, Dr. Ou will consider a comprehensive set of risk factors to improve precision to the individual level. The results will allow him to design future larger-scale, multi-site retrospective replicative and eventually prospective clinical trials, to improve neurocognitive outcomes in this vulnerable population before and after treatment.

This grant is generously supported by the Grace for Good Fund, established in honor of Grace Carey and celebrates her survivorship from medulloblastoma. Her cancer journey began in 2007 when she was diagnosed at age 5 with a treatment regime that entailed surgery, proton beam therapy and chemotherapy. While Grace handled it all with minor setbacks, she now faces the physical, emotional and cognitive challenges wrought by the very medications and procedures that saved her life. This fund was inspired by Grace’s desire to help other kids with cancer and supports research of brain tumors and the multitude of challenges facing survivors post treatment.

Adoptive immunotherapy has demonstrated unprecedented clinical success in the treatment of leukemia. In this therapy, T cells are isolated from a patient, expanded outside of the body, and genetically modified prior to reinfusion. The ability of these T cells to recognize and eliminate cancer cells is improved by expressing a protein (CAR) on the T cell surface. This protein increases "specificity," the ability to recognize cancer cells, and "function," the ability to destroy those cancer cells. An important challenge in cellular immunotherapy is to minimize the manipulation of patients' T cells outside the body. Prolonged culture protocols trigger functional exhaustion and compromises their efficacy upon return to the body. A critical issue involves the pre-requisite "activation" step necessary for CAR expression on the cell surface of T cells. By optimizing culture conditions, Dr. Ghassemi developed approaches to express CAR in dormant T cells without the need for activation. Importantly, her preliminary findings show that elimination of this activation step retains effector function and potency of CAR T cells in models of the pediatric cancer ALL. This project is providing insight into the regulatory components influencing CAR expression in dormant T cells which will lead to superior CAR T cells for cellular immunotherapies against ALL.

This grant is supported by TEAM ABBY Gives, a St. Baldrick's Hero Fund. Abby was diagnosed with Pre-B ALL when she was almost five years old. She had a successful bone marrow transplant, but battle battled graft vs. host disease (GVHD) for years. Abby and her treatment team worked hard over many years to keep the GVHD in check. Sadly, Abby passed away on October 19, 2021. This fund unites the incredible support of family and friends in Abby's memory and inspires others to join the fight for cures and better treatments.

Cancer cells rely on specific nutrients for growth and survival, rendering nutrient restriction as a potential therapeutic strategy. Along this line, acute lymphoblastic leukemia (ALL) cells have been found to be dependent on exogenous supply of asparagine, a nonessential amino acid, for protein synthesis. As a result, depletion of asparagine in the blood stream by L-asparaginase, a chemo-agent, has been successfully used to treat pediatric ALL for 40 years. However, ALL patients can develop resistance to the continuous application of this chemo-agent. Dr. Zhang is determining how ALL cells become resistant to L-asparaginase treatment, and therefore to provide experimental evidence of novel therapeutic targets that can potentially improve the outcome in pediatric ALL patients.

Ewing sarcomas are bone cancers that impact many adolescents and young adults. Despite the use of intensive traditional chemotherapy combined with advanced surgical techniques, 30-40% of patients still die after the disease eventually spreads to other organs, such as the lungs and bone marrow. Dr. Hayashi's team believes the key to overcoming this problem lies in the identification of “Circulating Tumor Cells (CTC)”. These are cells that break away from the original tumor and travel through the blood stream, eventually taking root in another organ to form what is called metastatic disease, meaning the cancer has spread from where it started into different areas of the body. These cells undergo multiple changes in order to leave the original tumor and survive in the harsh environment of the blood stream, eventually leaving the blood stream to invade another organ where they multiply and grow. This project aims to dissect each of these complicated steps with the goal of unveiling which element of this devastating process can be targeted to disrupt it.

People always say we need to outsmart cancer to beat it. As the Hope with Hazel St. Baldrick's Scholar, Dr. DuPage is not sure we will ever be able to do this with simple chemicals or radiation beams. Not only are these strategies rarely specific for the cancer cells alone, often leading to severe side effects that can be lifelong, but cancers always find a way around these single agents and "relapse." What if we could use a "living drug" to treat cancer? A drug that was as wiley and adaptable as the cancer itself and would last for a lifetime? A smart drug! Our own immune systems are capable of fighting our own cancers with extreme precision if we can train them to do it. This research is focused on understanding how cells of our immune system interact with tumor cells and how we can train our own immune cells to fight our own cancers. It is called cancer immunotherapy, and for children with cancer, Dr. Dupage thinks there are no better patients because their young and healthy immune systems are perfectly suited to be trained to fight cancer, removing the need for procedures that can manifest dangerous side effects in adulthood, and safely protecting them for life.

This grant is named for the Hope with Hazel Fund in honor of Hazel Hammersley who was diagnosed with Stage III neuroblastoma at age 2. She endured treatments, surgeries and two relapses with an amazing ability to push through and live life to its fullest. She loved her family and her happy place was with them. Through Hazel, her family learned that no one can fight pediatric cancer alone. This fund remembers her love of life and is dedicated to raising awareness and funds for research to protect kids with cancer who are still in the fight.

Sarcomas are tumors of the bone and soft tissues that comprise up to 20% of cancer diagnoses in children. Despite dismal outcomes for patients with recurrent or metastatic disease, treatment regimens have remained largely unchanged for decades – intense non-specific chemotherapy combined with surgery or radiation. Dr. Tulpule studies Ewing’s sarcoma (ES), a bone tumor caused by a unique genetic change that creates a tumor-specific protein EWS-FLI1. To date, no drug has been identified to directly block the cancer causing EWS-FLI1 protein. His research takes a different approach to combating ES by asking a fundamental question: can we identify a targetable weakness in ES tumors that is caused by the EWS-FLI1 protein? Using a cutting-edge screening technology called CRISPR interference, Dr. Tulpule's team identified a specific vulnerability in ES cells’ capacity to repair damage to their DNA. Normal cells have many backup systems in place to repair DNA damage, but they have shown that EWS-FLI1 causes ES cells to become overly reliant on a single pathway, known as homologous recombination (HR) repair, such that blocking HR is an effective and specific way to kill ES. Dr. Tulpule is building a detailed understanding of why ES cells are so vulnerable to HR pathway blockade and then applying that knowledge towards developing less toxic and more effective treatments for ES patients.

Despite improvements in outcome for patients with acute lymphoblastic leukemia (ALL), up to 25% of children and 40% of adults fail frontline therapy and their prognosis is dismal, especially for high-risk and relapsed leukemia. Cure rates for ALL patients that are relapsing on therapy is approximately 20% and currently there are no targeted therapies. Dr. Tsirigos' goal is to address this significant clinical need by studying how DNA, our genetic material, is organized inside the nucleus of the cells, i.e. how it is folded in three-dimensional space. Over the past decade, seminal studies have demonstrated that DNA folding is of fundamental importance in that it allows the cell to properly perform its function and retain its identity (e.g. a liver cell versus a blood cell). Very recent studies have demonstrated that disruptions of DNA folding may cause various diseases, such as developmental defects and cancer. However, no study has addressed the question of disruptions of DNA folding on the genome-wide scale in cancer or how such disruptions may be exploited for more effective treatments. Dr. Tsirigos is attempting to answer two key questions. First, are cancer-promoting genes (“oncogenes) capable of disrupting normal DNA folding to transform normal cells into malignant ones? And, second, can drug treatment restore DNA folding and thereby also restore normal cell function?

This grant is made with generous support from the Rally for Ryan Fund. Ryan was diagnosed with high risk ALL when he was 7 years old. He endured 3½ years of treatments with a brave acceptance that this was his fight to win. He recently relapsed and is in the fight again. This fund honors Ryan’s perseverance and his commitment to make a difference for kids with cancer by shaving for St. Baldrick’s and raising funds for research.

Based on progress to date, Dr. Osborn was awarded a new grant in 2022 and 2023 to fund an additional year of this Scholar grant. Abnormal growth of B-cells can result in leukemia, and a cutting-edge treatment option is immunotherapy with T-cells. T-cells can be engineered to express a chimeric antigen receptor (CAR) that is a 'seek and destroy' molecule for the CD19 protein on B-cells. CAR T-cells are the first FDA approved gene therapy and some stunning therapeutic responses have been observed. However, the T-cell activity can be so robust that they cause a massive cytokine storm that can be lethal. Furthermore, normal and cancerous B-cells express the CD19 protein targeted by the CAR, so normal B-cell loss occurs resulting in an impaired immune system. These side effects represent a significant hurdle in the safe and effective treatment of B-cell leukemia. To address this, Dr. Osborn, will express the CAR in a specialized subset of cells called T-regulatory (Treg) cells. Tregs have the same potent killing ability as T-cells but accomplish it without healthy tissue collateral damage. Additionally, he will engineer functional B-cells that are invisible to the CAR. This will allow for normal B-cell numbers and an intact immune system. Dr. Osborn will conduct these studies that are structured to resolve an unmet need, are highly novel, and are poised to make an immediate impact on childhood leukemia. 

The 2022 portion of this grant is named for the Rays of Hope Hero Fund which honors the memory of Rayanna Marrero. She was a happy 3-year-old when she was diagnosed with Acute Lymphoblastic Leukemia (ALL). She successfully battled ALL, but a treatment induced secondary cancer claimed her life at age eight. Rayanna had an amazing attitude and loved life. She, like so many kids facing childhood cancer, did not allow it to define who she was. This Hero Fund aspires to give hope to kids fighting cancer through research.

A portion of this grant was funded by and named for the Mighty Mimi Hero Fund. Mimi Enyon was diagnosed with acute lymphoblastic leukemia at the age of 3. Her courage in the fight was unparalleled and she became “Mighty Mimi” to all those she inspired on her way to remission. This fund was established to share Mimi’s cancer journey in an effort to raise awareness and funding for childhood cancer research for kids like her.

A portion of this grant is generously supported by the Stanley Kuzmickas Feeney Fund for Pediatric Cancer Research. It was Christmas 2015 when Stanley was diagnosed with acute lymphoblastic leukemia at 13 months old. He courageously endured treatments for 3½ years. Today, he is in remission and eagerly started school in fall 2019. In his honor, Stanley’s family has organized a head-shaving event each year since July 2016 called “StoshyStrong." With the funds raised, the Feeney family created this Hero Fund to support research in new discoveries, genomics and other biological therapies for the treatment of ALL. Their goal is to one day see personalized treatments for every child.

Children with high-grade gliomas, such as glioblastoma multiforme, have few therapeutic options and usually die of their disease. CAR T cells recognize protein targets on cancer cells and kill those cells. Many brain tumors express target proteins on only some of their cells and therefore cannot be efficiently treated with a CAR T cell that recognizes only one target. Therefore, Dr. Majzner aims to make T cells that can recognize up to four targets. He is exploring the best way to achieve specificity (the narrowness of the range of substances with which an antibody or other agent acts or is effective) for four antigens including using gene editing in order to make CAR T cells that can come from a healthy donor but be used in any patient.

A portion of this grant is funded by and named for the Be Brooks Brave Fund. Despite his diagnosis at age 5 with inoperable brain and spinal tumors, Brooks taught so many people what life is truly about--love. He was BRAVE beyond his years with an inspiring “faith over fear” attitude. This Hero Fund hopes to raise money for high-grade glioma research so no other family will hear the words, “there is no cure”.

A portion of this grant was also generously co-supported by the McKenna Claire Foundation, a St. Baldrick's partner and the Living for Luker Brain Tumor Research Fund, a St. Baldrick's Hero Fund. The McKenna Claire Foundation was established by the Wetzel family in memory of their daughter, McKenna. Their mission is to cure pediatric brain cancer by raising awareness, increasing community involvement and funding research. The Living for Luker Brain Tumor Research Fund was established in memory of Luke's love for life and caring for others. He was diagnosed at age 10 with Diffuse Intrinsic Pontine Glioma, a rare, uncurable cancer and never gave up hope throughout treatment.

Today, over 80% of children diagnosed with cancer in high income countries like the United States will survive. Considered a miracle of modern science, these gains are unfortunately not reflective of outcomes for the 90% of children with cancer who live in low- and middle-income countries (LMIC). Yet, as many LMIC continue their epidemiological transition away from overwhelming infectious disease to a greater non-communicable disease burden, cancer care has recently become a major global focus. As policy-makers now begin the cancer control and prioritization planning process to meet this challenge, estimates of global and national cancer-related disease burden are a critical piece of data required when making decisions. However, current efforts meant to generate global pediatric cancer burden data such as incidence, mortality and long-term morbidity measures are not ideally suited for this purpose as they are optimized to measure adult cancer burden and do not incorporate key pediatric-specific data sources. Instead, a pediatric cancer specific analysis is needed since children are sufficiently different from adult cancers such that new methods, which account for small numbers of cases, the lack of etiologic risk factors, histology-based classification codes, and the long-term effects of treatment, are required. As the Friends for Hope Fund St. Baldrick's Scholar, Dr. Bhakta will address this critical gap by producing comprehensive pediatric cancer-related burden estimates using the most current data sources and rigorous statistical estimation methods. It is anticipated the results of this study (to be published and made publicly available) will provide global stakeholders and policymakers key outcomes data to cure more children with cancer globally.

This grant is named for the Friends for Hope Fund created to honor Morgan Loudon and celebrates her strength and determination as a cancer survivor. Diagnosed when she was 9 with a rhabdoid tumor, today she has no evidence of disease. Through this fund, Morgan's family and friends hope to 'battle on' in the search for cures and better treatments.

The lives of children surviving cancer are cut short by life-threatening infections. Most pathogens causing these infections come from the gut. Healthy children have good bacteria in their gut that protect them from pathogens. Chemotherapy and antibiotics harm good bacteria in the gut that protect children from pathogens. Without good bacteria, pathogens increase in the gut. These pathogens can get into the bloodstream and cause serious infections. Prior studies have repeatedly shown that replacing healthy stool with good bacteria in the gut is the best treatment and prevention of gut infections. Dr. Andersen's team is developing a new test that detects the good bacteria and pathogens in the gut using a stool sample. This new test will allow earlier identification of children with cancer at the greatest risk for a serious infection and the children most likely to benefit from replacing healthy stool with good bacteria back in their gut. They believe that replacing good bacteria in the gut can prevent serious infections from pathogens, including those with limited antibiotic treatment options. This new test will also identify the specific good bacteria in the gut that prevent infection for developing new probiotics to prevent serious infections in children with cancer.

There is a new and effective cancer treatment for some incurable pediatric blood cancers. The treatment involves programing a patient's own cells to destroy their tumor, a process called cellular immunotherapy. Despite great effort to use cellular immunotherapy to treat 'solid' tumors, which include tumors of the bones, muscles and other parts of the body, we have not been successful yet. One major reason is that the programmed patient cells are designed to recognize a single marker on a cancer cell. In some blood cancers, all of the tumor cells express the same marker increasing the likelihood that cellular immunotherapy can cure the patient. Solid tumors are more heterogeneous than blood cancers, meaning each solid tumor cell may express a different marker. Therefore, cellular immunotherapy is less likely to destroy all solid tumor cells and the chances of achieving a cure is much more difficult. A potential solution is to trigger the body's own immune system to destroy tumor cells that express many different markers, a process called "epitope spreading". Named as the David's Warriors St. Baldrick's Scholar, Dr. Leibowitz focuses his project on testing strategies to augment epitope spreading in pediatric solid tumors so that cellular immunotherapy may become an effective and viable treatment option in the future.

This grant is named for and generously supported by the David’s Warriors Hero Fund created in memory of David Heard who battled neuroblastoma and inspired his family and countless others to commit to raising money for research to fight pediatric cancer. This fund honors the amazing spirit in which he lived, embracing life until the very end.

Do you ever get a cold sore on your lip, or know someone who does? That sore is caused by a virus that destroys the cells in your lip. As the virus spreads, the sore gets bigger. Viruses are great at killing cells and spreading. But, the sore eventually goes away because the immune system attacks the infected cells, killing them and stopping the viral infection, allowing your lip to heal. Imagine if we could get both the virus and the immune system to kill cancer cells instead of lip cells! Previously Dr. Haworth's team used a safe version of the cold sore virus to infect a common type of hard-to-treat childhood cancer cells. The virus directly killed cancer cells and caused the immune system to attack the cancer cells that the virus missed. Dr. Haworth's team is testing ways to make the virus and immune system work better together. Dr. Haworth is infecting model tumors with the virus, and giving immune cells designed to attack the tumor, hypothesizing that giving both virus and immune cells will cure the tumor. Awarded at The Research Institute at Nationwide and transferred to St. Jude Children's Research Hospital.

Brain tumors are the leading cause of cancer-related deaths in children, and ependymomas are the third most common kind. Recent studies have shown that educating the patients own immune system to fight cancers immunotherapy can be safe and effective. Dr. Kohanbash's team has identified three peptides that might activate immune cells to specifically fight one of the more lethal types of ependymoma. Dr. Kohanbash is testing these peptides in the lab. He is also looking at how immunotherapy could help fight all six types of ependymoma that affect kids, and thus is studying relevant characteristics in the largest-ever series of pediatric ependymoma tumors as well as in ependymoma patients already participating in a clinical trial of a vaccine based on another peptide.

A portion of this grant is generously co-supported by the Henry Cermak Fund for Pediatric Cancer Research and the Team Campbell Foundation. The Henry Cermak Fund for Pediatric Cancer Research, a St. Baldrick's Hero Fund was created in memory of a brave boy who had an amazing spirit throughout his battle with a brain tumor. This fund is dedicated to Henry’s wish that “no one gets left out.”

The Team Campbell Foundation, a St. Baldrick's partner, was established in memory of Campbell Hoyt, who courageously battled anaplastic ependymoma, a rare cancer of the brain and spine for five years. Its mission is to improve the lives of families facing a childhood cancer diagnosis through raising awareness, funding research and providing psycho-social enrichment opportunities.

A portion of Dr. Kohanbash's grant was also generously supported by the Henry Cermak Fund for Pediatric Cancer Research.

Based on progress to date, Dr. Ladle was awarded a new grant in 2020 to fund an additional year of this Scholar grant. As the Aiden's Army Fund St. Baldrick's Scholar, Dr. Ladle is using the body's own immune system to destroy cancer - specifically a class of cancer in children originating from connective tissues called sarcomas. Using fire as an analogy, Dr. Ladle seeks to build an intense flame of a powerful immune response which will specifically kill the cancer cells. To create this fire, one must follow specific steps. The kindling, which must be easily burned, is protein targets on the cancer cells (termed tumor antigens) recognized by the immune system. Next, the spark to ignite the kindling is initial inflammation in the tumor against these tumor antigens. Finally, to feed the fire, fuel or lighter fluid can be added in the form of recently approved immune modulator drugs which, when infused into patients, bind to immune cells residing in the tumor and activates them to kill the tumor cells. Each ordered step is essential in building an effective fire. This project addresses each of these key aspects for generating a successful immune response to treat sarcomas and creating new tumor antigens, adding inflammation to jump start the immune response against these antigens, and combining with new immune modulators allowing the immune cells to be active in destroying sarcomas.

Women who are diagnosed with cancer before 40 are often concerned about whether they will be able to have children in the future. Women can freeze their eggs or embryos (called fertility preservation) to help protect their fertility, but these services may not be widely available. Dr. Nichols has looked at how often women in North Carolina have children after cancer treatment and whether the health of their babies is different from women without cancer. She is further examining the use of fertility preservation after diagnosis and its association with birth rates and outcomes. This research will provide information to improve the long-term health of AYAs with cancer.

The EWSR1-FLI1 family of cancer genes causes Ewing sarcoma. However, no drugs currently exist that specifically block the action of EWSR1-FLI1 to cause cancer cells to grow. The McFadden Lab has engineered a "self-destruct button" into the EWSR1-FLI1 gene in Ewing sarcoma cells cultured in the laboratory, and these cells stop growing when the EWSR1-FLI1 gene is turned off. Dr. McFadden is using this laboratory tool to identify proteins that work with EWSR1-FLI1, and identify other genes it controls to cause Ewing sarcoma cells to grow. These studies will help identify new ways to stop the growth of Ewing sarcoma cells.

Rhabdomyosarcoma is a pediatric cancer of the developing skeletal muscle. The mechanisms that drive this tumor are poorly understood. From Dr. McEvoy's preliminary analysis, one possible mechanism is epigenetic deregulation of a group of long noncoding RNAs (lncRNA). This is exciting because lncRNAs play a role in tumorigenesis in other cancer types, including a subset of pediatric tumors. This presents a unique opportunity to develop novel therapeutic approaches for children with rhabdomyosarcoma. Dr. McEvoy's team hypothesizes that lncRNA deregulation is essential for rhabdomyosarcoma development. This study is working to understand the underlying mechanisms that drive this disease and identify potential new therapies. These results will have tremendous impact on patients, especially those with metastatic disease since only 20-40% will survive using current treatments.

Based on progress to date, Dr. Cimmino was awarded a new grant in 2020 to fund an additional year of this Scholar grant. Vitamin C is essential for maintaining healthy hair, skin, immune system and heart function. In addition to these health benefits, Dr. Cimmino and team propose that vitamin C might be a non-toxic therapeutic for the treatment of patients with pediatric acute myeloid leukemia. Recently, it was discovered that vitamin C enhances the activation of a group of enzymes called TET proteins that are required for normal blood development. A significant fraction of children and young adolescents with acute myeloid leukemia have mutations in TET2, causing impaired TET2 activity and a block in normal blood cell formation. However, only one of the two copies of the TET2 gene is defective in these patients. Dr. Cimmino's team is working to determine if treatment with high-dose vitamin C could enhance the activity of the remaining, non-mutant, TET2 protein, kill leukemia cells and restore normal blood development. Alternative therapies such as treatment with vitamin C might provide a safe and effective strategy to improve outcome for pediatric leukemia patients. Awarded at the New York University School of Medicine, and transferred to University of Miami.
