Four Kalamazoo College students attended at the 2014 Experimental Biology Meeting: Amanda Bolles ’14, Chemistry; Rina Fujiwara ’15, Chemistry; Virginia Greenberger ’14, Chemistry; and Michael Korn ’14, Biology. Experimental Biology is a joint meeting of six different societies including the American Association for Biochemistry and Molecular Biology (ASBMB) as well as societies for physiology, nutrition, pharmacology, pathology, and anatomy. The meeting provides a great opportunity for students to present their work and attend a variety of engaging scientific talks. More than 15,000 scientists attended the event in San Diego, Calif.

Bolles and Fujiwara presented their research findings during the Undergraduate Poster Competition and during the regular scientific session for ASBMB. Their research involves recent work completed in the laboratory of Professor of Chemistry Laura Furge. That work has shown that two different (but related) compounds inactivate P450 3A4, an enzyme in the liver and intestine that metabolizes (or processes) a major pharmaceutical drug. The titles of the Bolles and Fujiwara posters were, respectively, “5-Fluoro-2-[4-[(2-phenyl-1H-imidazol-5-yl)methyl]-1 piperazinyl]pyrimidine is a mechanism based inactivator of CYP3A4” and “Mechanism-based inactivation of human CYP3A4 by a piperazine-containing compound.” The ASBMB competition includes posters of some 300 students from a variety of college and universities across the country. One grand prize award was presented to a student in each of four research categories (bioenergetics/protein structure, cell biology/developmental biology, DNA/gene regulation, and immunology/microbiology/neurobiology). Bolles won the $500 grand prize in the bioenergetics/protein structure category and was recognized the next day before an audience of hundreds of scientists, educators, and students at the award lecture for outstanding contributions to education. Bolles’s presentation derived from her Senior Individualized Project (SIP), which will be published later this year along with results from co-author Fujiwara.

Greenberger conducted her SIP research in the laboratory of Professor of Chemistry Regina Stevens-Truss. The abstract she presented at the meeting was titled “Bacterial Action of Novel Cationic Peptide Sequences.” As more antibiotic resistance is observed in patients, new sources of antibiotics are being investigated, including short peptide sequences. Greenberger’s work in the Truss lab was aimed at determining the antibiotic activity (and the precise mechanisms of action that yielded the activity) of two newly studied peptide sequences.

Dr. Furge also presented a poster in the ASBMB regular scientific session based on work started last year by Parker de Waal ’13. The work began as part of a course assignment in Furge’s “Advanced Biochemistry” course and grew into an elegant computational study of structural differences between select variants of the drug-metabolizing enzyme P450 2D6. de Waal used molecular dynamics methods to show how subtle differences in the enzyme structure can help explain differences in the metabolizing abilities of the enzymes. The study is being completed by Kyle Sunden ’16. While in San Diego, Furge spent an afternoon at the Skaggs School of Pharmacy at the University of California-San Diego discussing the implications and approach of the study with other scientists in this field.

Korn attended the American Physiological Society (APS) portion of the Experimental Biology meeting. He presented the results of his SIP work (conducted in the laboratory of Dr. Christopher Mendias at the University of Michigan) in the APS Student Poster Competition. Korn’s abstract received the David Bruce Outstanding Undergraduate Abstract Award. The title of his presentation was “Simvastatin reduces myosteatosis following chronic skeletal muscle injury.”

The future is promising for all four of these outstanding student researchers. In the fall, Bolles will enter the University of Michigan Graduate Program in Biomedical Sciences; Greenberger will matriculate to the chemistry department at Pennsylvania State University to begin work on her Ph.D; Korn will attend the University of Michigan Medical School; and Fujiwara will complete her SIP with Furge this summer. She plans to attend graduate school after her June 2015 graduation from K.

Professors Furge and Truss are both members of the ASBMB and attend the annual meeting each year. Truss also directs a National Science Foundation (NSF)-funded workshop for area high school science teachers in connection with the annual ASBMB meeting. This year’s workshop attracted more than a dozen local teachers who learned science and teaching strategies to use in their classrooms. Attendees at the workshop are also eligible for mini-grants to support further development of their teaching after the workshop. A recent article describes the impact of this workshop (which is in its fourth year).

In other meeting news, the Ruth Kirschstein Diversity in Science Award was given jointly to President Freeman Hrabowski III and Professor Michael Summers of University of Maryland-Baltimore County. Professor Summers was the SIP mentor to Erran Briggs ’14 and has worked closely with Professor Truss on the Professional Development and Minority Affairs Committees of ASBMB. Professor Summers also visited K’s campus in 2010 as a Howard Hughes Medical Institute Guest Scholar Lecturer. Given the connections, and important work of Summers and Hrabowski, Professor Truss arranged for Bolles, Fujiwara, and Greenberger to interview Summers for Kalamazoo College’s Arcus Center for Social Justice Leadership’s Praxis Center. Following the interview, Summers treated the students and Truss to lunch overlooking the San Diego Harbor marina! Notes from the interview will be posted on the Praxis website.

Travel to ASBMB for Bolles, Fujiwara, and Greenberger was supported by grants from the Provost Office, the Heyl Foundation (Greenberger), and the ACSJL. Korn’s travel to the meeting was sponsored by grant funds from his SIP advisor and the University of Michigan. Furge and Truss were supported by the Hutchcroft Endowment as well as their NIH and NSF grants, respectively. Next year’s Experimental Biology Meeting will occur in Boston, Mass.

The Bees’ Needs

Rachel Mallinger

The power of science in large part is the power of great storytelling. When the stories lead into mystery … well, that’s when science continues, generating more stories and encountering more mysteries. The University of Wisconsin-Madison’s Genetics/Biotech center harnesses the power of stories during a public series called Wednesday Nite @ The Lab, occurring every Wednesday, 50 times a year. Attendance is high, and K alumna Rachel Mallinger ’05 will be the featured presenter on Wednesday, March 26. Her topic: “Wisconsin’s Wild Bees: Who Are They, What Do They Do, and Why Should We Conserve them?” Rachel earned her B.A. in biology at K, her M.S. in entomology and agroecology (UW-Madison) and is currently pursuing her Ph.D. in entomology at UW-Madison. Wisconsin has more than 500 species of native wild bees, and their contributions to pollination are becoming more and more important as honey bee populations decline. Mallinger’s talk will focus on effect of land use change and farm management on the abundance and diversity of wild bees. “I will also discuss the role of wild bees in crop pollination, and address whether or not they can fulfill our food needs,” she wrote. Mallinger wants to learn more about the roles of insects in agricultural ecosystems and how insects can be managed to enhance the sustainability of farming. She currently studies wild bees and pollination services within fruit orchards. She enjoys working with farmers, experimenting in her own vegetable garden, and cross-country skiing during the winter. At K, Rachel studied abroad in Thailand, and she also mentored a SIP student supervised by Ann Fraser, associate professor of biology. According to Fraser, that student is now applying to Ph.D. programs to work on wild bees. “That will make at least four grads in the last eight years who have done to work on wild bees,” adds Fraser. “I’ll be working with three students this summer on another bee project (looking at the impacts of honey bees on wild bees), and a student organization on campus is starting work on constructing ’buzz boxes’ on campus to improve foraging and nesting habitat for wild bees. Maybe,” grins Fraser,” we need a new college mascot.” The hornet’s probably safe for now.

Research Sheds Light on Liver Cancer Pathway

Posted on

Diane DeZwaan ’05 is conducting cancer research in the Department of Anatomy and Cell Biology at the University of Iowa Carver College of Medicine. She is one of the authors of a research article whose impact of has been much larger than expected. The article, which appears in the journal PLOS/Genetics, is titled “The Stress-Regulated Transcription Factor CHOP Promotes Hepatic Inflammatory Gene Expression, Fibrosis, and Oncogenesis.” Her research provides evidence of a chain of events that leads to the formation of liver cancer (hepatocellular carcinoma, or HCC), the third most common cause of cancer death worldwide. Liver cancer is most commonly caused by viral hepatitis, alcoholism, or obesity, all of which activate cell stress in the liver. DeZwaan’s research may be the first that links  elements of this stress response–specifically the expression of a stress-regulated transcription factor called CHOP–to the appearance of cancerous tumors in the liver.  The research also showed that exposure (in mice) to a tumor-causing agent when CHOP is absent results in fewer tumors and less cell death. The findings of the research establish CHOP as a biological marker for liver cancer and showed its importance in promoting liver tumor formation. It’s possible that the genesis of tumors by CHOP is a common feature of liver cancer. The research raises intriguing questions that require additional research, which may lead to important new insights into the development of liver cancer. The editors of the magazine were so taken by the potential of the work that they contributed a perspectives article (“The Integrated Stress Response in HCC: Not Just CHOPped Liver”) on it. Television and print media outlets in Iowa have published stories on DeZwaan’s research. As an undergraduate at K DeZwaan majored in biology, studied abroad in Australia, and played on the Hornet basketball team.

Research Published on Alzheimer’s Molecules

Posted on

Biology professors Jim Langeland ’86 and Blaine Moore join one K student and three K alumni as authors of an important paper that will soon be published in the journal Molecular Biology and Evolution. The co-authors are Nathalie Botezatu ’14, Maddie Gillentine ’13, Ashley (Boehmke) Benson ’08, and Kyle Wilson ’08. All were (or are) biology majors at K, and in the case of some, the scientific work—which describes the evolution of key molecules involved in Alzheimer’s disease—was part of a Senior Individualized Project (SIP). The work is groundbreaking in at least two ways. First, it approaches Alzheimer’s disease from an evolutionary perspective. And second, it illustrates a particular niche approach to research that the scientific environment at K is well positioned to pull off.

“The experiments that culminated in this paper began in 2007 with the SIP work of Benson and Wilson,” says Langeland. “The six-year duration shows that science can take a long time to come to fruition.” That duration derives, in part, from the complementary expertise of the two collaborating labs—Langeland’s expertise in gene evolution and Moore’s background in Alzheimer’s disease research and experience with cellular expression of proteins.  According to Langeland, for most of the larger labs the exigency of understanding Alzheimer’s in order to development treatments for it may not favor such an extended timeline or evolutionary approach. Indeed, Moore says, “Most researchers in the Alzheimer’s field are exclusively focused on inhibiting the production of protein fragments that have been linked to the progression of the disease. One of the exciting aspects of this project was the chance to take a broader view of the proteins involved in the disease process.”

A broader view allows for unique approaches (suggesting that time and creativity are the two pillars of the particular niche approach to research for which K is so well-equipped). Six years ago Langeland decided to investigate the evolution of two molecules associated with Alzheimer’s—APP and BACE. BACE acts like a scissors to cut (or cleave) APP. The excess accumulation of one of the “cut pieces” (a.k.a. products or substrates, this particular one known as A-Beta) is linked to the development of the disease. Benson and Wilson sought answers to how far back on the evolutionary tree of life these molecules could be found. Turns out that APP is nearly a billion years old. BACE (and its cleavage effect) is much younger, about 500 million years old. Just down the hall, Moore’s lab had been studying the regulation of enzymes that produce A-Beta, and had well-developed systems for expressing Alzheimer’s proteins and analyzing cleavage products. Put the two together and you have a unique project that would have been unlikely at a larger institution or medical school.

The principle of natural selection suggests that BACE’s action on APP is vital to life in ways we don’t yet understand, according to Langeland. The A-Beta substrate may be some kind of mistake that natural selection is unable to “correct” because Alzheimer’s expresses so late in human lifetimes, usually long after reproductive success has been achieved. Moore says, “It’s essentially a wrong place, wrong time phenomenon. The APP substrate evolves the A-Beta motif, then comes in cellular contact with preexisting BACE. The result is a devastating disease process that is most likely an accidental by-product of some normal, as yet unknown, cellular process.”

Moore and his lab (including Gillentine and Botezatu) conducted an elegant experiment to confirm the importance of the BACE molecule. They expressed the BACE molecule from an organism—in this case a primitive marine dweller called amphioxus—that diverged from the human evolutionary branch some 750 million years ago. Amphioxus has no A-Beta. Then, Moore’s group discovered that amphioxus BACE nevertheless acts as a scissors to the human APP molecule. The result adds evidence to the biological importance (albeit unknown) of BACE’s cleaving action.

According to Langeland, an evolutionary approach to diseases may suggest molecular targets for treatment intervention, and, just as important, the limitation of a non-nuanced approach to potential targets.

The paper is titled “Asynchronous Evolutionary Origins of A-Beta and BACE-1.” The work was supported, in part, by a Great Lakes Colleges Association (GLCA) New Directions Initiative Grant, a program that supports professional growth of mid-career liberal arts faculty, with particular emphasis on projects outside traditional boundaries.

Seven K representatives accept Green Generation Customer of the Year award
Consumers Energy (CE) named Kalamazoo College as its 2013 Green Generation Customer of the Year. From left are Binney Girdler, K associate professor of biology; Emma Dolce ′14, sustainability intern; Katie Ray ′14, sustainability intern; Paul Manstrom, K associate vice president for facilities management; Lisa Gustafson, CE business customer care director; Thomas Shirilla, CE business account manager; and Kevin Linders, CE senior corporate account manager.

[Sept. 27, 2013] Consumers Energy has named Kalamazoo College its “Green Generation Customer of the Year” in recognition of the College’s overall sustainability effort and its voluntary participation in this renewable energy program.

The 1,450-student liberal arts and sciences college located midway between Detroit and Chicago purchases 720,000 kilowatt-hours (KWh) of renewable energy annually from Consumers Energy, enough to supply 8 percent of the College’s total electrical usage.

“Sustainability is a strong focus at Kalamazoo College. Receiving this award lets us know that others recognize our commitment to the environment and that gives us reason to be proud,” said Paul Manstrom, K’s associate vice president for facilities management. “We began purchasing electricity through the Green Generation program as part of a project to renovate the Hicks Student Center on campus to standards developed by the U.S. Green Building Council, earning the first LEED Silver certification in southwest Michigan in the process. We’ve found that participating in Green Generation has been a great fit for us.”

Kalamazoo College has been a Green Generation participant since January 2009. It’s one of the Top 10 participants in the Green Generation program, having purchased more than 2.5 million KWh of renewable energy since enrolling. The recently-completed Athletics Field House and the Arcus Center for Social Justice Leadership (currently under construction) will be the two “greenest” buildings on campus, furthering the college’s sustainability credentials.

“It’s with great enthusiasm we single out the achievements of Kalamazoo College in supporting renewable energy efforts in Michigan,” said Thomas Shirilla, Consumers Energy’s program manager for Green Generation. “K’s leadership in this voluntary program is commendable. It demonstrates commitment to and optimism for Michigan’s future.”

Past Green Generation customer of the year recipients are Irwin Seating, Grand Rapids Community College, University of Michigan – Flint, Dow Corning, City of Grand Rapids, and Wolverine Worldwide.

Consumers Energy’s Green Generation program has nearly 17,000 customer-participants and was the first voluntary renewable energy program in Michigan. It was launched in 2005 following authorization by the Michigan Public Service Commission. More than 100 organizations are enrolled in the Green Generation program.

Green Generation has led to the development of several renewable energy projects in the state, including the Michigan Wind 1 park in the Thumb region. Other Green Generation projects include biomass facilities located near Birch Run, Lennon, and Marshall. Consumers Energy also purchases electricity for the program generated by wind turbines near Mackinaw City. All of the projects are located in Michigan’s Lower Peninsula and all sources are Green-e certified as renewable.

The Green Generation program offers Consumers Energy’s electric customers an opportunity to support renewable energy by enrolling in the voluntary program and paying a small premium. Program information is available at .

Kalamazoo College (www.kzoo.edu) was founded in 1833 in Kalamazoo, Michigan. It is the oldest college in Michigan and among the 100 oldest institutions of higher learning in the United States. K is a nationally recognized liberal arts and sciences college with nearly 1,450 students and the creator of the K-Plan that emphasizes rigorous scholarship, experiential learning, leadership development, and international and intercultural engagement. Kalamazoo College does more in four years so students can do more in a lifetime.

Consumers Energy, Michigan’s largest utility, is the principal subsidiary of CMS Energy (NYSE: CMS), providing natural gas and electricity to 6.6 million of the state’s 10 million residents in all 68 Lower Peninsula counties.

Healthy Body May Mean Healthy Bacteria

Posted on

Rob Dunn ’97 is extensively quoted (and his best-selling book cited, The Wild Life of Our Bodies: Predators, Parasites, and Partners That Shape Who We Are Today) in an article by Nancy Churnin that appeared in the Dallas Morning News’ “Dallas News Life.” The article, “Be nice to your bacteria and they’ll be nice to you, doctors say,” notes a growing belief among experts that good health is strongly influenced by the ecology of the multitudes of bacteria that reside in our bodies and in our natural environment. It cites examples of probiotic treatment, or the introduction of bacteria as a therapeutic measure to restore the balance of bacterial populations in the body. It is a fascinating read, and Dunn is at his curious K best, equating excitement with the new found extent of all we don’t know. Dunn is a scientist and professor at North Carolina State.

The Art of a Scientist

Posted on

Kalamazoo College alumnus Dan Van HornWhen Dan Van Horn ’50 earned his degree in biology, focusing on ornithology, at Kalamazoo College, he came to science with an eye for art. A visit to the Indiana Dunes during his college years intrigued Van Horn, drawing his eye to plant life, but also to the resident birds. Alongside biology, Van Horn studied watercolor painting, but after graduating and going into military service, he switched from watercolor to photography.

Van Horn went on to graduate school to earn a master’s and then his doctoral degree in zoology at the University of Colorado. He was a professor of biology at several colleges and universities, later also a founding member of the University of Colorado-Colorado Springs biology department shortly after the branch opened in 1966. Since retiring from teaching, he has immersed himself in art again, winning many awards. He is a signature member of four national watercolor societies, and in 2013, Van Horn was selected for the American Watercolor Society’s 146th Annual Exhibition. The show is traveling to many venues across the United States throughout 2013.

Van Horn lives in Colorado Springs, Colorado, with his wife, but because he grew up in Chicago, many of his watercolors feature that city.
