TSU Medical Researcher Leads Fight Against Brain Tumors

NASHVILLE, Tenn. (TSU News Service) – People suffering from brain tumors could receive better medical care as a result of research currently being done by one of Tennessee State University’s leading medical scientists.

Dr. Quincy Quick, TSU associate professor of Biology, said by investigating the protein Microtubule Actin Crosslinking Factor 1 (MACF1), he hopes to help doctors target brain tumors using a precision method approach and thereby provide more effective therapy.

“All cancers are different,” he said.  “Even though you and I may have a brain tumor, we would have different types of brain tumors because our genetics are different.  Therefore, the genetics of our tumors would be different.”

According to Quick, if two patients had brain tumors and one patient’s tumor expressed the MCAF1 protein and the other didn’t, doctors would be able to use his research to better determine which type of therapy would best treat each tumor.

“Cancers have a lot of different components.  You treat a tumor with radiation or chemotherapy.  The reality is that some of those cells in the tumor would be killed, and some of them wouldn’t be,” he said.  “The idea is how do you then identify one target that would kill all of the cells within the tumor population.  MCAF1 would be thrust into that category as a potential target that could be inhibited and kill all the cells in the tumor and not just the subpopulation of those cells.”

According to brain tumor experts at the National Institutes of Health (NIH), there are more than 130 different types of brain tumors, and about 80,000 people in the U.S. are diagnosed with a primary brain tumor each year.

Currently, four students assist Quick with different aspects of the research project which began in August and is funded for four years by the National Institute of General Medical Sciences (NIGMS) in NIH.

Orica Kutten, a sophomore biology major from Ghana, said working in the lab with Quick has given her direction for her career path.

“Initially, I just wanted to go to medical school,” she said. “But now I am thinking of possibly going to research school and furthering my studies in cancer research.”

Kutten, a member of the TSU Honors College, said the lab work has introduced her to techniques she will need to know whether she attends medical school or graduate school.

“I love working in the lab with Dr. Quick,” she said. “He has been a great mentor, and I am very grateful for all the things I have been able to learn in his lab.”

Quick explained that the process for introducing new methods of treatment for brain tumors is slow in the United States, but patients diagnosed with these tumors can receive better medical care by asking their doctors more informed questions.

He advises those suffering from brain tumors to ask their doctor if they are using a precision method approach.  Specifically, he said, patients should ask, “Are you evaluating the genetics of my specific tumor for me as an individual so that I can receive the best individualized therapy for me as opposed to taking the generic approach you would take with anybody that is characterized with this kind of tumor?”

Quick said the technology is available to make certain distinctions between the types of brain tumors, but often doctors don’t use it, and patients don’t know to ask the doctors to evaluate the genetics of their tumors so they can receive the best therapy.

“That’s a huge part of the problem,” he said.  “You need to be informed about the technology you are asking about so when the doctor gives you a response, you can make an appropriate decision like, ‘Do I need to go get a second opinion?’”

Dr. Edith Mitchell, Noted Cancer Specialist, TSU Graduate Named to Biden’s Cancer Moonshot Blue Ribbon Panel

NASHVILLE, Tenn. (TSU News Service) – Renowned cancer specialist and TSU alum, Dr. Edith P. Mitchell, is part of a panel that recently submitted 10 cutting-edge scientific recommendations to help speed the development of cancer cures.

Mitchell, clinical professor and director of the Sidney Kimmel Center to Eliminate Cancer Disparities at Thomas Jefferson University, served on the Blue Ribbon Panel of scientific leaders and cancer patient advocates named to provide direction for Vice President Joe Biden’s National Moonshot Initiative.

President Obama announced the $1 billion initiative as part of his State of the Union Address in January and named Biden to head it. The Moonshot aims to make more therapies available to more patients, while also improving efforts to prevent cancer and detect it at an early stage.

In September, Mitchell’s panel submitted their report, with recommendations aimed at the Moonshot goal of making 10 years of progress in five years.

“Serving on the Moonshot Blue Ribbon Panel is one of the most exciting things that has occurred in my career,” said Mitchell, who is also outgoing president of the National Medical Association. “As members of the panel, we were able to take what we know from experience from cancer and working with cancer research to come up with these recommendations, which we are certain will help the vice president in his work.”

The panel recommended that the Moonshot consider the following:

  • Establish a network for direct patient involvement
  • Create a clinical trials network devoted exclusively to immunotherapy
  • Develop ways to overcome resistance to therapy
  • Build a national cancer data ecosystem
  • Intensify research on the major drivers of childhood cancers
  • Minimize cancer treatment’s debilitating side effects
  • Expand use of proven prevention and early detection strategies
  • Mine past patient data to predict future patient outcomes
  • Develop a 3D cancer atlas
  • Develop new cancer technologies

Mitchell, a retired Air Force brigadier general, is one of Tennessee Gov. Bill Haslam’s nominees for Tennessee State’s University Board of Trustees.

NASHVILLE, Tenn. (TSU News Service) – A Tennessee State University scientist and a group of researchers from Washington University School of Medicine at St. Louis have come up with an experimental vaccine for breast cancer that appears to be safe in a preliminary trial.

According to a study published in Clinical Cancer Research, Dr. Venkataswarup Tiriveedhi, assistant professor of Biological Sciences in the College of Agriculture, Human and Natural Sciences, and his colleagues found that the experimental vaccine, Mammaglobin-A, was “overexpressed” in 40 to 80 percent of primary breast cancers.

Also known as MAM-A, the vaccine prompted CD8 T-cells to track and eliminate the MAM-A protein, noted Tiriveedhi. To determine the efficacy and safety of the experimental drug, he said they conducted a phase I trial involving 14 patients diagnosed with advanced breast cancer.

“The side effects from the vaccine after one year were minimal, and included rashes, tenderness, and mild flu-like symptoms,” added Tiriveedhi, who specializes in cancer and immunology.

By the one-year mark, the study revealed, roughly 50 percent of the patients showed no sign of disease progression. By comparison, only 20 percent of a similar group of 12 patients showed no signs of disease progression one year out.

The researchers, however, stressed the need for a larger and longer study, to prove the current preliminary evidence prior to its use in all breast cancer patients. They theorized that “these promising results” from initial studies could be applied not only to prevent cancer progression but also to prevent the development of breast cancer in women.

“The current one (study) is a small Phase-I trial mainly aimed at testing the safety (does no harm). But we have also found this vaccine to be highly effective against the disease. The next step is to go for larger Phase II/III studies with a higher cohort of breast cancer patients and rigorously test for efficiency, dosing, clinical outcomes, cancer stage specificity, etc.,” noted Tiriveedhi, who holds MD and Ph.D. degrees.

He called the study a “promising move forward” that is not just restricted to breast cancer, but one that can be employed in “similar strategies” to treat other cancers such as lung and colon cancers.

“The MAM-A DNA vaccine is safe, capable of eliciting MAM-A–specific CD8 T-cell responses, and preliminary evidence suggests improved PF,” the researchers concluded.

Dr. Tiriveedhi, who came to Tennessee State University about a year and half ago, started the study, “Safety and Preliminary Evidence of Biologic Efficacy of a Mammaglobin-A DNA Vaccine in Patients with Stable Metastatic Breast Cancer,” with his colleagues at Washington University before leaving to join the faculty at TSU.
