Two years of research create lasting impact for Nigerian visiting scholar
By Sarah Rubinstein | Bond LSC Michael Arowolo is a visiting professor in the lab of Dong Xu, a Bond LSC principal investigator. | photo by Braiden Wade, Bond LSC The African proverb “it takes a village to raise a child” can especially apply in science where that village includes mentors like Dong Xu, a Bond Life Sciences Center principal investigator, who has trained hundreds of students and collaborators. Michael Arowolo, is among those mentored, having spent the past two years in Xu’s lab as a visiting scholar. In August, he will take that experience with him to…

You shall not pass: the basic science of blocking HIV
Marc Johnson, associate professor of molecular microbiology and immunology at the Bond Life Sciences Center, studies viruses such as HIV. | photo by Jennifer Lu, Bond LSC Nineteen colorful foam flowers decorate the walls of Marc Johnson’s office, a memento from his lab members when they “redecorated” while he was out of town. Each flower is labeled in bold Sharpie with the names of viruses and viral proteins that his lab studies—MLV, RSV, Gag, Pol, to name a few. One flower stands out, marked in capital letters: H-I-V. Johnson, an associate professor of molecular microbiology…

Putting down roots
Plant scientist Ruthie Angelovici joins the Bond Life Sciences Center By Jennifer Lu | MU Bond Life Sciences Center Ruthie Angelovici Ruthie Angelovici clearly remembers her big eureka moment in science thus far. It didn’t happen in a laboratory. It wasn’t even her experiment. At the time, Angelovici was in college studying marine biology. She had spent a year going on diving trips to figure out whether two visibly different corals were polymorphs of the same species, or two separate species. A simple DNA test told her the answer in one afternoon. “That’s the day I decided…

Five things you wanted to know about epigenetics (But were afraid to ask)
What the heck is it, anyway? Epigenetics involves changes in how your genes work. In classical genetics, traits pass from generation to generation in DNA, the strands of genetic material that encode your genes. Scientists thought alterations to the DNA itself was the only way changes could pass on to subsequent generations. So say you lost a thumb to a angry snapping turtle: Because your DNA hasn’t changed, your children won’t be born with smaller thumbs. Classic. Things get way more complicated with epigenetics. It turns out that some inherited changes pass on even though they…

“Mutant seeds” blossom in the pollen research field
A mutant arabidopsis model nearing pollination. Mutant arabidopsis models under lamps in Shuqun Zhang’s lab. Three-month-old mutant arabidopsis models are used to study the function of pollen. The thought of pollen dispersed throughout the air might trigger horrific memories of allergies, but the drifting dander is absolutely essential to all life. Science has long linked this element of reproduction with environmental conditions, but the reasons why and how pollen functions were less understood. Now lingering questions about the nuanced control of plants are being answered. “Pollen is a very important part of the reproductive process and…

The only thing you need to read about Ebola today: An expert Q&A
Jingyou Yu, a graduate student, does cell surface staining in Shan-Lu Liu’s virology lab. The staining illuminates cell marker expressions in experiments that deduce how viruses spread once they are contracted. | Paige Blankenbuehler News headlines seem to feverishly spread as if they were a pandemic of the brain. Ebola hemorrhagic fever has been the most talked about disease of the year, appearing in thousands of headlines across the world since May. Through the noise of misinformation and sensationalism, fundamental information about the pandemic becomes harder to distinguish. In an interview with Decoding Science on Tuesday, Shan-Lu Liu, MD,…

Viruses as Vehicles: Finding what drives
Graduate students Yuleam Song and Dan Salamango inoculate a bacteria culture in Johnson’s lab. The inoculation takes a small portion of a virus and multiplies the sample, allowing researchers to custom-make viruses. By Madison Knapp | Bond Life Sciences Center summer intern Modern science has found a way to turn viruses —tiny, dangerous weapons responsible for runny noses, crippling stomach pains and worldwide epidemics such as AIDS— into a tool. Gene therapy centers on the idea that scientists can hijack viruses and use them as vehicles to deliver DNA to organs in the body that…

Researchers flex new muscle in SMA drug development
By Paige Blankenbuehler Lauren and Claire Gibbs share contagious laughter, ambition and a charismatic sarcasm. Both are honor students at Shawnee Mission East High School in a Kansas City suburb. They also share a neuromuscular disease called spinal muscular atrophy (SMA), designated as an “orphan disease” because it affects fewer than 200,000 people in the U.S. However, the landscape for individuals with SMA is quickly changing with the development of new drugs. More than 7 million people in the United States are carriers (approximately 1 in 40) of the so-called “rare” neurodegenerative disease, SMA. Lauren,17 (left) and Claire, 16 (right),…

Hearing danger: predator vibrations trigger plant chemical defenses
Experiments show chewing vibrations, but not wind or insect song, cause response As the cabbage butterfly caterpillar takes one crescent-shaped bite at a time from the edge of a leaf, it doesn’t go unnoticed. This tiny Arabidopsis mustard plant hears its predator loud and clear as chewing vibrations reverberate through leaves and stems, and it reacts with chemical defenses. Plants have long been known to detect sound, but why they have this ability has remained a mystery. University of Missouri experiments mark the first time scientists have shown that a plant responds to an ecologically relevant sound in its environment. “What…

Nerve cell communication mechanisms uncovered, may lead to new therapeutic approaches for neurodegenerative diseases
Story by Madison Knapp/ Bond Life Sciences summer intern Simple actions like walking, swallowing and breathing are the result of a complex communication system between cells. When we touch something hot, our nerve cells tell us to take our hand off the object. This happens in a matter of milliseconds. This hyperspeed of communication is instrumental in maintaining proper muscle function. Many degenerative diseases affecting millions of people worldwide result from reduced signaling speed or other cellular miscommunications within this intricate network. Michael Garcia, investigator at the Christopher S. Bond Life Sciences Center and associate professor of biology at…

SoyKB: Leading the convergence of wet and dry science in the era of Big Data
Yaya Cui, an investigator in plant sciences at the Bond Life Sciences Center examines data on fast neuron soybean mutants that are represented on the SoyKB database. The most puzzling scientific mysteries may be solved at the same machine you’re likely reading this sentence. In the era of “Big Data” many significant scientific discoveries — the development of new drugs to fight diseases, strategies of agricultural breeding to solve world-hunger problems and figuring out why the world exists — are being made without ever stepping foot in a lab. Developed by researchers at the Bond Life…

New screening tool gives scientists more control over genetic research
A tangled spool of yarn represents DNA, while the fingers holding the section represent the insulators just added by MU researchers to improve a scientific, screening tool. | Paige Blankenbuehler Here’s a scenario: You are trying to find a lost section of string in the world’s most massively tangled spool of yarn. Then try cutting that section of yarn that’s deeply embedded in the mess without inadvertently cutting another or losing track of the piece you’re after. For researchers, this problem is not unlike something they encounter in the study of genetic information in the tangled…
