Pelotonia Funds Awarded by Ohio State Cancer Program to Seven Research Teams for Innovative Studies

COLUMBUS, Ohio — Seven groups of cancer researchers have received a funding boost to investigate innovative scientific ideas thanks to funds generated through Pelotonia, a grassroots cycling movement established in 2009 to raise money for cancer research at Ohio State.

The 2015 Pelotonia Idea Grants Program research projects range from first-in-human testing of a cancer-fighting virus based on the common herpes virus to laboratory studies aimed at improving our fundamental understanding of the role of stem cells in the most common form of brain tumors (glioma) and adult leukemia (chronic lymphocytic leukemia).

In the past five years, 74 OSUCCC – James research teams have received Pelotonia Idea Grants, which provide support for two years. Awardees are selected through a peer-review process conducted by both internal and external scientists not competing for grants in the current funding year. A total of $760,000 will be awarded in this latest round of Pelotonia Idea Grants, with $7.4 million in funding awarded since the program’s inception.

“The steadfast generosity and enthusiasm of our community makes it possible for us to fund the ideas of innovative scientists who have come to Columbus, Ohio, to conduct cancer research. For that, we are profoundly grateful and humbled,” says Michael Caligiuri, MD, director of OSUCCC and chief executive officer of the James Cancer Hospital and Solove Research Institute. “There is no routine cancer research, and none of these projects would be possible without the thousands of Pelotonia riders and donors who are bringing us closer each day to creating a cancer-free world.”

Summaries of the spring/summer 2015 Idea Grant projects follow here.

Herpes-Based Virus to Attack Solid Tumors

This team will test a new therapy for treating childhood and young-adult cancer. Oncolytic virus therapy uses live viruses to selectively infect and kill cancer cells, with minimal damage to normal tissue. Once in cancer cells, the anticancer virus is designed to kill cancer cells as it replicates and spreads to adjacent tumor cells. The goal is more complete and precise treatment of the tumor. This Pelotonia Idea grant will support a first-in-human study of a locally developed oncolytic virus based on the herpes simplex virus-1. Part of the Translational Therapeutics research program, this study is the first step toward determining whether the virus can shrink solid tumors outside the central nervous system.

Tumor Suppression and Genome Stability

Tumor-suppressor genes protect cells from developing into cancer. When these genes are mutated or silenced they can no longer protect the cell and this contributes to cancer development. Fhit is a tumor-suppressor gene that is lost in most human cancers, but scientists do not completely understand how or why its loss contributes to cancer development. In this study, researchers with the OSUCCC – James Molecular Biology and Cancer Genetics Research Program will identify Fhit-regulated genes that control cell survival, proliferation and invasiveness with the goal of identifying new targets for drugs that might help treat more than 50 percent of all cancer cases.

Improving Chemotherapy Effectiveness in Breast Cancer

Many kinds of chemotherapy kill cancer cells by damaging the DNA of rapidly dividing tumor cells. At the same time, some cancer cells survive the treatment due to their ability to repair DNA damage and their use of checkpoint signaling pathways. This study examines ways to disrupt or block DNA repair and cell-signaling pathways that enable cancer cells to survive chemotherapy and radiotherapy treatments that are designed to kill them. Specifically, it could define whether blocking a certain signaling pathway in the presence of chemotherapeutic agents could improve chemotherapy effectiveness in breast cancer. This study is also supported by the Stefanie Spielman Fund for Breast Cancer Research.

Stem Cell Resistance in Chronic Lymphocytic Leukemia (CLL)

Stem cells are cells that give rise to other cells in a tissue. A small proportion of cancer cells also have qualities of stem cells and are thought to play an important role in cancer development and resistance to chemotherapy. Leukemia-generating stem cells are widely accepted in myeloid leukemia, but little is known about the role of leukemia stem cells in the most common form of adult leukemia, CLL. In this study, researchers will evaluate a new technology for identifying potential stem-like CLL cells, determining whether they are true leukemia stem-like cells, and then learning more about their biology. The findings could lead to new and more effective treatments for CLL. The study is part of the OSUCCC – James Leukemia research program.

Defining Prostate Cancer Aggressiveness Through DNA Sequencing

Male hormones, such as testosterone, are known as androgens. Decades of research have demonstrated that androgens are necessary for the development and progression of prostate cancer.  In addition, antiandrogen hormone therapy has been a critical intervention in prostate cancer treatment. Although dramatic responses are often seen, the antiandrogen therapy ultimately fails as the cancer evolves to a treatment-resistant state. Exactly how androgens stimulate cancer growth and how resistance to antiandrogens occurs is poorly understood. The proposed research of this study — which is based in the Molecular Carcinogenesis and Chemoprevention research program — will provide a more precise understanding of the molecular and genetic events involved in these processes while helping to define markers that enhance our choices of antiandrogens for patients. This enhanced knowledge could result in the identification of androgen regulated targets and the development of more precise treatment approaches in prostate cancer.

Stem Cells’ Role in Brain Tumor Development and Spread

Gliomas are the most common tumor of the central nervous system and are difficult to treat, resulting in overall poor treatment outcomes. Researchers with the OSUCCC – James Translational Therapeutics and Molecular Biology and Cancer Genetics research programs believe that populations of cancer stem-like cells cause these tumors to be resistant to therapy. This project will take a closer look at the tumor microenvironment and cell communication pathways that support these clusters of stem-like cells in an effort to better understand how regulating these pathways could lead to future treatment modalities in glioma.

Mobile Health Intervention for HPV Vaccination

Human papillomavirus (HPV) vaccination in young adults age 18 to 26 is an effective strategy for reducing the burden of HPV-associated diseases like cervical cancer, however, vaccination rates are suboptimal among this population. In a new pilot study, researchers with the OSUCCC’s Cancer Control research program — in collaboration with the Wilce Student Health Center — will test a mobile health intervention to communicate with young adults about HPV-associated diseases and the HPV vaccine in an effort to increase uptake of the vaccine in this high-risk population.
