Village Walk for Cancer Research
The biochemistry department participated in the 18th Annual Village Walk for Cancer Research in Hot Springs Village. The walk is a fundraiser for cancer research at WPRCI. Funds from last years walk are currently funding a project addressing drug resistance in lymphoma in Samantha Kendrick‘s lab. Also walking were Stephanie Byrum, Alicia Byrd, and Tung-chin Chiang.

Allie Davis and Binyam Belachew receive white coats
Allie Davis, a graduate student in Dr. Paul Miller’s lab, and Binyam Belachew, a graduate student in Dr. Kevin Raney’s lab received their white coats at the UAMS Graduate School’s annual Research Induction Ceremony celebrating Ph.D. candidates who have successfully passed their qualifying exam in the past year. Congratulations Allie and Binyam!
Allie Davis Elected to Two Professional Groups
Allie Davis, a graduate student in Dr. Grover Paul Miller’s lab has recently been elected to two different groups.
Allie was elected to serve on the International Society for the Study of Xenobiotics (ISSX) New Investigator Group. This group comprises promising new investigators (predoctoral, postdoctoral, and new to their careers) that recruit and retain new ISSX members and promote interaction and collaborations between new members and more experienced members to ensure a lively and diverse group for many years to come. Currently, the new investigator group is writing up a conference proceedings paper that covers the ISSX international meeting from this past July.
Allie was also selected to serve on the Drug Metabolism Reviews (DMR) editorial board. Being a predoctoral student, access to many editor friends and colleagues she’s met at conferences and events will help her to learn the editorial process. Allie was selected for this group because she is a promising new investigator who has shown that she is willing and able to communicate and collaborate with scientists across many branches with varying degrees of experience.
Congratulations Allie!
Graduate Student Explores Potential of Handheld DNA/RNA Sequencers in Outbreaks
By Amy Widner
Imagine there’s an outbreak of an infectious disease. Could health officials on the ground harness the power of new handheld DNA and RNA sequencers to monitor outbreaks in real-time and quickly contain them?
This question lies at the heart of research published in the journal Infection, Genetics and Evolution by UAMS Biochemistry and Molecular Biology track graduate student Duah Alkam. She and her advisers from the College of Medicine Department of Biomedical Informatics and the Department of Microbiology and Immunology collaborated with the Arkansas Department of Health to look at specimens collected during a 2016 mumps outbreak in Northwest Arkansas.
It took the Human Genome Project 13 years to complete the first sequence of a human genome in 2003. As sequencers became available for purchase, they were large, expensive and slow.
![Alkam holding tech in palm of hand](https://news.uams.edu/wp-content/uploads/2019/09/Duah-Alkam_9509-375x249.jpg)
That has changed. Alkam used a device called the Oxford Nanopore Technologies MinION to sequence each sample in a matter of hours. To offload the data, she simply connected the MinION through a USB port to a laptop.
“You see results on your computer in real time,” Alkam said. “It’s fast, affordable and simple. The idea is that something like this might be useful during an outbreak, especially in a rural setting. If you can quickly identify a strain, you’re that much closer to understanding the origin of the outbreak, which may help contain it and protect the at-risk population.”
The new challenge for scientists is how to interpret the massive amount of data produced by these powerful sequencers. That is where the relatively new field of biomedical informatics comes in.
“Biomedical informatics allows us to look at genomes within a matter of hours and compare them, pinpointing connections and what might be important about these datasets,” Alkam said. “In this way, biomedical informatics is sort of the bridge between raw data and relevant information.”
In this case, Alkam was able to determine the unique characteristics of the specific variation of the mumps virus that was behind the 2016 outbreak. They used a computational technique called immunoinformatics to plot a “family tree” of sorts for the virus.
“We found that it was very similar to a strain that started an outbreak in Massachusetts around the same time in 2016, and it was also related to another strain that spread in Washington state, which may suggest that all three outbreaks originated from the same strain.”
While Alkam’s experiment was not conducted during an active outbreak, she and her advisers believe the results demonstrate great promise for the technique to be applied in the real world. Earlier in 2019, other scientists in the Department of Bioinformatics collaborated with researchers around the world for the first demonstration that the MinION could be used for the rapid genetic sequencing of multiple human viruses.
“The possibility of infectious disease outbreaks in health care settings and communities is something that unites us across the globe. We’re all vulnerable,” said Se-Ran Jun, Ph.D., Alkam’s adviser for the project and an assistant professor in biomedical informatics. “So at UAMS, it’s exciting each time we demonstrate how we can harness the power of new sequencing technology, big data science and analytics, and high performance computing in biomedical informatics to offer solutions.”
The project was funded with a grant to Jun from the UAMS for Translational Research Institute.
Alkam is a student in the UAMS Graduate School’s Graduate Program in Interdisciplinary Biomedical Sciences (GPIBS). Her other advisers are David Ussery, Ph.D., a professor in the Department of Biomedical Informatics; and Mark Smeltzer, Ph.D., a professor in the Department of Microbiology and Immunology.
