During a membership event April 29, the Cincinnati Cancer Center awarded over $200,000 in pilot grants to members and basic scientists who are collaborating to find out more about various cancers with hopes of generating more data and additional funding.
Three teams received Affinity Group Awards to encourage multidisciplinary research efforts and link CCC programs.
Cincinnati Cancer Center
member Shao-Chun Wang, PhD, assistant professor in the department of cancer
biology and member within the UC Cancer Institute, says there are two major
challenges in treating breast cancer: determining how aggressively to treat the
cancer in its early stages and overcoming the recurrence of cancer metastases
after years of the cancer cells resting or remaining dormant after surgery or
anti-cancer drug treatments.
These questions are
the focus of Wang’s project, funded by a $60,000 CCC affinity grant.
with CCC co-investigators Susan Waltz, PhD, professor in the department of
cancer biology, and Jiang Wang, MD, PhD, associate professor in the department of
pathology and laboratory medicine, who are also members in the UC Cancer
Institute, are trying to understand the mechanisms that control the
aggressiveness of early-stage tumors and that "wake up” dormant tumor cells
residing in distant organs throughout the cancer patients’ body.
collaboration, the group has successfully identified a signaling pathway in
which the Ron receptor tyrosine kinase, a cell surface protein frequently found
activated in breast cancer, controls the activity of PCNA, a nuclear protein
playing a key role for cancer cells to spread. This work, which was just
published in the journal Oncogene,
together with other unpublished results of the team, points to the potential
importance of the Ron-PCNA pathway in determining the aggressiveness of breast
cancer at both the primary and the metastatic sites.
"The PCNA protein can
easily be regulated by cancer-causing pathways to enhance cancer cell growth,”
Wang says. "These pathways can be exploited as treatment targets to prevent
tumor recurrence and as biomarkers to help physicians assess how aggressively to
treat early stage breast cancer.”
In addition to using
animal models, Jiang Wang of the team is providing pathological expertise so
that they can also investigate the activities of this pathway in human tumor
tissues for its role in cancer development as well as patient outcomes.
"This project is
extremely relevant to the current problems in the therapy of breast cancer,”
Waltz says. "With this funding, we can build preliminary data to gain funding
for a larger research project that could help us one day provide better
outcomes for patients with recurrent breast cancer.”
The University of
Cincinnati, Cincinnati Children’s Hospital Medical Center and UC Health have
created the Cincinnati Cancer Center—a joint effort designed to leverage the
strengths of all three organizations in order to provide the best possible
cancer diagnostics, research, treatment, and care for individuals in the
Tristate region and the nation. To learn more, visit cincinnaticancercenter.org.
