Marshall University professor Vincent Sollars recently received a $432,000 grant from the National Cancer Institute for his unique cancer research. It involves something called canalization.

Click this picture to hear Clark Davis interview Dr. Vincent Sollars about his research.

Dr. Sollars is an associate professor in the Marshall University School of Medicine. He’s taking an unusual approach to find better treatments for cancer.

“In the end what we’re looking at is making life better for people that have this deadly disease, that’s the main reason I became a scientist,” Sollars said.

The idea of canalization is that as cells develop and mature they become different things.

“As they develop they start as very immature cells that look like each other, and then they mature,” Sollars said. “That process is structured and they’re pushed a long a certain direction like a canal pushes water.”

And he said when that canalization does not work appropriately that is when cancer cells develop. Sollars is examining why some of those cells do not follow the path and end up becoming cancerous. Sollars said that some of the cells will stop listening and cooperating with neighboring cells. That communication with the other cells is necessary for the complex mix that becomes the different cells in our body. When the cells do not listen, bad things happen.

“The loss of this canalization is a force that will allow those cells that are normal to become cancerous, if we understand how that occurs we can develop new chemotherapies,” Sollars said. “If it is truly a force that helps a cancer cell progress we can put breaks on that force.”

Sollars and a team of student researchers will the test the role of canalization in the maturing process of cells and cancer development in mice. They will target leukemia specifically with this grant, but the results can apply to all cancer types. Sollars said most often with cancer research, the examination is of the genes that mutate and become cancerous. His work differs because it looks at the process those individual cells are taking in becoming a normal part of the body or cancer down the road.

“What I’m doing is understanding not a particular gene, but a process,” Sollars said. “So how do cells bring about the changes in these genes, not the specific genes themselves, but the process and so this is a fundamental process is my theory that most cancers use to progress.”

Sollars says ultimately the hope is that if his hypothesis can be proved true, a certain type of chemotherapy could be used in conjunction with the already occurring treatment of leukemia. He says often times the initial treatment of leukemia will seem successful, putting the cancer into remission. But often he said cancer cells will be hiding and growing without the knowledge of the doctor until it’s too late.

Sollars hopes to hire 8 undergraduate and graduate students along with a full-time technician.

It’s called ChemoID, and it could represent a big step forward in cancer care.

Nearly a decade ago, two Marshall University professors met on this bridge, which connects the Science Building and the Byrd Biotechnology Center. That moment of serendipity, of blind chance bringing two people together, was the beginning of a relationship which led to combining research and work leading to revolutionary new way to fight cancer.

ChemoID_VideoIt’s a new paradigm in cancer treatment,” Dr. Jagan Valluri, Marshall University professor said. “Simply because this particular assay that we developed is simply going to deliver great results in improving clinical outcomes. And more importantly there is a lessening of the financial burden on patients because the assay is going to select the right chemotherapy for that particular patient.

“A particular patient will respond to a certain drug better than another patient,” Dr. Pier Paolo Claudio, Marshall University professor said. “Why is that? Because those cancers are, although they look the same, they are really different. You and I, we are different genetically, so is cancer. And so, therefore the different response is due to that. So our test is a functional test that is able to find, select correct drugs, more useful drugs for that individual patient. And deselect those that are not useful that would cause more harm than benefit.

Identifying the best treatment for cancer has long been the subject of comprehensive research. The Marshall professors developed their second-level test, which subjects cancer stem cells to a multitude of different medicines.

Claudio says clinical tests show ChemoID is very effective and accurate in predicting which chemotherapy drugs or combination of drugs work best in individual cancer patients.

Let me illustrate how ChemoID works using this deck of cards. Let’s say each card is a federally-approved chemotherapy treatment against cancer and let’s say you’re diagnosed with lung cancer. So, your doctor picks a card. First generation testing is right about 60 to 70 percent of the time in choosing the right chemotherapy to deal with a general type of cancer. So, your oncologist picks this type of chemotherapy and it proves to be effective. But then another person is diagnosed with the exact same type of cancer. Their oncologist also prescribes this form of chemotherapy but it doesn’t work on them. So the oncologist is forced to go to a second type, this drug which is a little bit more effective. What the ChemoID researchers say is that their second generation test finds the correct medication to deal specifically with your type of cancer. They say that ChemoID will save money, it will save time and most importantly it will save lives.

“We have introduced a novel part to this test which is testing the cancer stem cell population,” Claudio said. “Which are the seeds of cancer, the roots of cancer. Just like normal tissue have stem cells, also cancer has stem cells. However, those are evil stem cells able to regrow and repair cancer following a failed chemotherapy. So if we leave those bad boys behind what happens is that cancer will recur. Our ability with this test is to select those cancer stem cells and grow them up so that we have material now to make a test and predict against cancer stem cells which chemotherapy will be more effective for selected patients, for individual patients.

Link to ChemoID interview“People have been trying to personalize chemotherapy,” Valluri said. “Because chemotherapy, when you provide chemotherapy to a patient it is generally based on clinical trials on generalized populations. It’s never specific to a patient group or subset of people. And so, what our process does is we minimize the trial and error by truly personalizing the chemotherapy and going after what we call the seeds of the cancer, the cancer stem cells. And so, the seeds of the cancer, if we can effectively target them and lower the load of the cancer stem cells there there is a greater clinical outcome.”

Finding the best chemotherapy option for each individual cancer patient could save time and avoid the harsh side effects of chemo treatments which aren’t most effective.

“Every person is different,” Claudio said. “So because every person is different, although every single card could be a good play to be played, drugs that may work better, we can find the drugs that can work better for that particular patient and therefore play that card instead of a different card.”

Clinical trials at the Edwards Comprehensive Cancer Center showed very positive results. ChemoID has been used to help dozens of patients during the testing period. One patient is celebrating six years of treatments. That’s six years longer than they were expected to live.

“By using the correct drug and by impacting more the cancer than the patient will in the end, prolong life and provide a better quality of life for patients,” Claudio said.

ChemoID is not a cure for cancer. But, for people with lung, brain, spine and breast cancer, it represents finding their best chance at making their disease chronic instead of fatal.

Claudio says an additional benefit is that ChemoID could save money. He and his partner recently talked with Senator Joe Manchin about their research and how it could cut Medicaid costs if its implemented on a wide basis.

“First of all, the quality of life, the ability to extend a person’s life that might be terminal,” Manchin said. “But the other thing is the amount of money that would be saved from treating so many different things that doesn’t have an effect.and being able to pinpoint what will be effective.”

The researchers say your oncologist, your doctor, will still have the final say as to which medicine they want to use to treat your cancer.

However, ChemoID is an additional tool which could give both doctors and patients more information about the best path to take and could provide an additional edge leading to longer and better quality lives.

“It’s gonna have an impact worldwide,” Valluri said. “Because when you think about in the U.S. alone we spend 30 billion dollars on chemotherapy drugs. The cost of cancer in this country alone is over 210 billion and it is a tremendous financial burden on patients. What this assay does is truly personalizes the chemotherapy selection. You’re not only reducing toxicity improving patient outcomes and reducing costs. So, there’s many facets to this technology.”

“By using this test,” Claudio said. “Oncologists can have a new pair of glasses that magnifies drugs that are working for that particular patient and can provide a benefit to the patient better than other drugs that wouldn’t.

Cabell-Huntington Hospital is planning to implement the new ChemoID cancer screening this fall.

The test’s creators say they hope to share the ChemoID technology with the hospitals across West Virginia, the nation and eventually the world.

Biomedical sciences researcher to present results of clinical trials on personalized chemotherapy

HUNTINGTON, W.Va. – Dr. Pier Paolo Claudio, a researcher at the Marshall University Joan C. Edwards School of Medicine, is traveling to Paphos, Cyprus, next month to present his work to personalize chemotherapy for cancer treatment.

Claudio was invited to give the talk at the 5th International Conference on Recent Advances in Health and Medical Sciences, which will be held July 6-12.

He will be discussing the results of clinical trials conducted at the Edwards Comprehensive Cancer Center. The studies tested ChemoID, a cell culture method he developed with colleague Dr. Jagan Valluri to measure the sensitivity of patients’ tumors to chemotherapy treatment for lung, brain/spine and breast cancer.

He says more evaluation of the technology is needed, but preliminary tests on a small number of patients found ChemoID 100 percent accurate in predicting which drug is more effective in treating patients affected by brain cancer if the tumor-initiating cancer stem cells were evaluated.

Claudio“Oncologists every day face many challenges in determining the best course of therapy for an individual cancer patient,” says Claudio. “The basic problem is that patients with similar diagnoses don’t always respond to the same chemotherapy. This technology we have developed could help physicians select the appropriate chemotherapy for an individual patient—giving them an edge in the fight against cancer.”

He says the good news for cancer patients is that ChemoID may make possible personalized treatment by predicting the most effective drug combination to successfully target that specific patient’s cancer—increasing the chance the drugs will work and perhaps reducing side effects by helping the patient avoid unnecessary drugs.

In addition to presenting his own research at the conference, Claudio will be moderating a session, “Advances in Oncology and Anticancer Research. Cancer Pathology.”

Summaries of the research presented at the meeting will be published in the journal Frontiers in Bioscience.

Researcher receives $432,000 grant to study progression of cancer, involve students

The following news story provides different information about Dr. Sollars’ research than the previous one posted on our News page.

HUNTINGTON, W.Va. – Dr. Vincent E. Sollars, an associate professor of biochemistry and microbiology at the Marshall University Joan C. Edwards School of Medicine, has received a $432,000 grant from the National Cancer Institute to research a cutting edge concept to fight cancer.

The Academic Research Enhancement Award (AREA) will fund a three-year project in “epigenetics,” a relatively new concept in cancer therapies that has shown great promise.

“The basic question we are trying to answer is ‘What are the processes that enable a normal cell to start misbehaving and become cancer cells?’” says Sollars.

As he explains, the process that cells undergo to become cancer cells ultimately produces a cell that stops listening and cooperating with neighboring cells. That communication, however, is necessary for the complex mixture of cells our bodies contain.

He says, “This grant will investigate a process known as ‘canalization.’ Much like a canal for water directs the flow of water, canalization directs a cell as it matures into the specific type of cell needed by the body. Disrupting the canalization process can cause a cell to change and lose its direction, potentially pushing it down paths that lead to cancer.”

Sollars said his team will be testing the role of Vincent-Sollars-2012canalization in the process of maturing cells and cancer development. They will be targeting leukemia specifically with this grant but the results of their study can apply to all types of cancers.

“We think our work can have a great impact on science’s understanding of  how cancer progresses and will even help develop new treatments for most cancers,” he added.

This particular award is specifically designed to give students practical opportunities to participate in cutting-edge academic research. Over the course of the project, Sollars anticipates involving eight students from Marshall’s undergraduate and graduate programs, as well as students from the medical school. The grant also will fund a full-time technician.

The National Cancer Institute, part of the National Institutes of Health, is the federal government’s principal agency for cancer research and training.

Grant to fund MU’s new cancer research

HUNTINGTON — A new concept in cancer treatment will be future explored at Marshall University thanks to a grant from the National Cancer Institute.

The U.S. Department of Health and Human Services (HHS) National Cancer Institute awarded a $432,369 three-year Academic Research Enhancement Award to the Marshall Vincent-Sollars-2012University Joan C. Edwards School of Medicine to launch a cancer biology research project in “epigenetics,” a relatively new concept in cancer therapies, according to a press release from Rep. Nick Rahall, D-W.Va.

The concept deals with a new chemotheraputic target in cancer treatment, said Dr. Vincent E. Sollars, an associate professor of biochemistry and biology at Marshall.

“It’s a great way for me and the students to get involved in some research I’ve wanted to do for some time,” Sollars said. “We’re targeting leukemia specifically with this grant, but the this could have ramifications on all types of cancers.”

Over the course of the three-year project, Marshall University anticipates involving eight students from undergraduate, master’s and doctoral academic programs, as well as students enrolled in the med school.

Sollars said the medical school also will hire a full time technician through the grant.
