Each year, Danielle Benoit leaves her Therapeutic Biomaterials Lab at the University of Rochester to host the Annual Benoit Laboratory Lemonade Stand at the Rochester and Brighton public markets.

Benoit and her students serve lemonade and explain their work on childhood cancer therapies as part of a national effort organized by Alex’s Lemonade Stand Foundation, which has helped fund her research.

“Most people don’t realize that treating cancer in children is much different from treating cancer in adults,” says Benoit, an assistant professor of biomedical engineering. “At the same time, funding for childhood cancer research is woefully miniscule, compared to the money that goes into studying adult cancers.”

Benoit’s community outreach is one reason she is the recipient of the 2016 Young Engineer of the Year Award from the Rochester Engineering Society. The award recognizes outstanding achievement in and contributions to the profession by young engineers in the Rochester region and promotes the importance of engineering practice to society.

Benoit, who joined the University in 2010, is an international leader in developing therapeutic biomaterials with applications in bone and salivary gland regeneration and treating dental caries and childhood cancers.

“Her work is creative, and transformative,” says Diane Dalecki, chair of the Department of Biomedical Engineering. “She is a true and creative engineer, applying principles of classical chemical engineering and materials science to new biomedical applications in medicine.”

This has resulted in numerous patents; several federal, state, foundation and industry grants – including a prestigious National Science Foundation Faculty Early Career Development (CAREER) Award -- and such professional awards as the 2015 Young Innovator Award in Cellular and Molecular Bioengineering.

Benoit also is “an outstanding educator, dedicated to training the next generation of engineers,” Dalecki says. Benoit teaches a core biomaterials course for undergraduates and courses in biomaterials and drug delivery for graduate students. She annually mentors students working on senior design projects and undergraduates who participate as Xerox fellows in a summer research program.

"Danielle is an outstanding faculty member, whose research in new biomaterials will have a large impact on therapeutics for a number of diseases and whose teaching and service demonstrate her dedication to the educational and outreach missions of the Hajim School," says Wendi Heinzelman, dean of the school.

Benoit's community outreach also includes inviting an elementary school class to her laboratory each year for a day of learning and hands-on experimentation. “Importantly, Dr. Benoit always involves her whole lab in these events, thereby instilling the importance of community outreach to the next generation of engineers in training,” Dalecki says.

Fifth graders visit Benoit Lab for demonstration and hands-on testing

A local entrepreneur club comprised of fifth graders interested in science and the business aspects of science recently contacted the Benoit lab after conducting one of the outreach experiments the lab shared online. The module demonstrates diffusive drug delivery through hydrogels, and they were interested in conducting another hands-on demonstration alongside the scientists behind the activity. Professor Benoit invited them to the Benoit Lab, where they met with lab members, took a mini tour, attended a presentation on hydrogel mechanics, and did some hands-on mechanical testing of hydrogels. The takeaway: gels made with lower weight percents are softer, and gels made with higher weight percents are stiffer, allowing us to tailor hydrogel constructs for our desired tissue engineering applications.

Ken Sims of Benoit Lab receives NRSA funding

Ken Sims, a PhD student working in the lab of Danielle Benoit, has received funding from the Ruth L. Kirschstein National Research Service Award (RRSA) Individual Predoctoral Fellowship program (F31).

His project is titled, "Engineered pH-Responsive Nanoparticle Drug Delivery to Inhibit Oral Biofilm Formation," and addresses the issue of tooth decay, which affects over two-thirds of children and nearly all adults worldwide and results in billions of dollars of direct and indirect healthcare costs each year. Most current treatment options involve topically applied drugs that provide little to no protection against tooth decay. The study will focus on designing a drug delivery system capable of penetrating dental plaque and releasing antibacterial drugs specifically where cavities develop: the acid covered tooth enamel surface. This research may lead to a new promising, clinically relevant therapeutic approach to prevent tooth decay and other oral diseases.

Teamwork toward a ‘Perfect Bullet’ for Leukemia

Wednesday, January 25, 2017

Imagine that a drug is “oil” and the human body is “water.” A conduit would be needed to steer cancer drugs through the body to selectively target cancer cells, wherever they reside.

If a budding Wilmot Cancer Institute investigation pans out, a nanoparticle-based delivery system might be exactly the conduit that scientists have been looking for, the trio of young researchers say.

Danielle Benoit, Ph.D., associate professor in the Department of Biomedical Engineering, Rudi Fasan, Ph.D., associate professor of Chemistry, and Ben Frisch, Ph.D., a research assistant professor in the Department of Medicine, Hematology/Oncology, are working together to improve the treatment of acute myeloid leukemia (AML), one of the deadliest types of blood cancers because it often relapses after initial therapy.

They each bring a different scientific discipline and a distinct role to the project. Fasan develops new drugs and new methods to make them more effective. In this case, he discovered and modified a small-molecule anti-cancer drug derived from a natural plant source related to the magnolia tree. After testing several different chemical forms of the compound, he is studying the correct potency and ability to precisely destroy cancer cells.

Professor Benoit’s nano-delivery system can transcend the barriers that sometimes prevent drugs from reaching their target. Nanoparticles are microscopic materials that act as a bridge between different structures—in this case the nanoparticles are designed to encapsulate an oily drug compound and make it more compatible with the body’s water. Her system also packages the drug with peptides (amino acids) that direct the treatment into the bone marrow, where leukemia takes root.

Getting to the root of the disease is important. Years ago, scientists discovered that leukemia most likely relapses because a subset of cells, known as leukemia stem cells, can dodge standard chemotherapy. Mature leukemia stem cells hide in the bone marrow in a quiet state, until they resurge. Wiping out these stem cells is the key to improving the treatment for a disease that can be very aggressive.

So far, scientists have not been able to target leukemia stem cells directly in the bone marrow, says Frisch, who studies the bone marrow environment for clues as to why blood cancers flourish there. His role is to take Fasan’s new drug, which will be loaded into Benoit’s nano-delivery system, and conduct experiments in cell cultures and mice to find out if the system is effective at binding to cancer cells.

“By using the proper materials to enhance drug delivery,” Benoit adds, “it could potentially revolutionize cancer treatment.”

The team won a 2016-17 University Research Award. Funded annually by UR President Joel Seligman, the money goes to scientists with projects that have a high probability of receiving additional external funding. They received $75,000 to generate data to compete for larger grants from the National Cancer Institute, the Leukemia and Lymphoma Society, and the Leukemia Research Foundation.

“The idea is to have a perfect bullet,” Fasan says. “A very nice feature of this collaboration is that we can take advantage of complementary expertise and run with it.”
