Harnessing the power of light to transform Organ-on-a-chip technology is the focus of new research by Sean Moore, MD and his research team. Dr. Moore, a professor and researcher in the Department of Pediatrics, is directing a project to combine Organ-on-a chip (OOAC) technology with bioluminescence to create a novel instrument allowing for real-time measurement of complex physiology in living cells. The new research is made possible through a $100,000 grant recently awarded to the Moore Lab by The Jefferson Trust.
Organ-on-a-chip technology represents a major step forward in preclinical research by more accurately reflecting human physiology. This technology more fully recreates the dynamic forces and physiology of the human body to create robust models which can accelerate the development of new medical treatments.
However, gathering data from the chips can be extremely challenging. Currently, detecting bioluminescence requires removing chips from the OOAC instrument and placing them into a separate device that lacks flow and stretch. This disruption makes real-time measurements impossible and increases risk of contamination.
Moore and his research team, Vinicios (Vini) Alves da Silva, PhD and Samir Muhammad and Georgia Brousseau, fourth-year UVA undergraduate students studying biomedical engineering, seek to combine OOAC with microphotomultiplier tubes to allow for real-time measurement of complex physiology. Through recombinant DNA technology, researchers engineer luciferase into the cells of humans to track the expression of individual genes and proteins. This luciferase produces light (think fireflies in the early evening) when exposed to compounds called “luciferins.”
Moore’s team plans to harness the power of bioluminescence to create a novel instrument (called OrChiD-Bio: Organs-on-a-Chip with Integrated Detection of Bioluminescence) that will allow scientists to detect bioluminescence in living cells implanted into organ-on-a-chip devices.
By adding integrative capabilities to OOAC systems, OrChiD-Bio will enhance their power as a biotechnology tool for precision medicine. According to the Moore team, “The future is bioluminescent!”
Moore Lab Becomes a GOLD Certified Green Lab!
We are thrilled to announce that this past year the Moore Lab became a certified Green Lab and was awarded with a gold medal, the highest level for this certification. This recognition resulted from a series of actions implemented by team Moore Lab to reduce the scientific research footprint and became a more sustainable place.
WHY BECOME A GREEN LAB?
While often overlooked, academic research labs are a significant contributor to greenhouse gas emissions, pollution, waste, and natural resource depletion. For example, laboratories typically consume 5 to 10 times more energy and at least four times more water per square foot than do office buildings. In a correspondence published in the journal Nature, it was estimated that bio-scientific research is responsible for 1.8% of total global plastic production! Academic labs just like ours go through a lot of consumables and throw away 12 billion pounds of plastic every single year! While some of this waste is hazardous, much of it isn’t and we can reduce our footprint by recycling much of the plastic used in labs.
The understanding shared in our lab is that science was meant to ameliorate human life and contribute to making a world better for everyone. With this understanding, it is not possible to pursue high-quality research while blinding ourselves to our footprint. By committing to environmental responsibility, our lab is taking ownership over its impact on the environment.
Our scientific track record has contributed to understanding how a bad environment could negatively affect the lifetime of children worldwide. And once it was said, knowledge brings responsibility, and becoming a certified green lab is another way of contributing to the betterment of the lives, not only of those children that are already here, but also of those that one day will come.
CAN MY LAB BE A GREEN LAB?
Yes! Your lab can be Green! We encourage you to pursue this certification. The Green Lab is a nonprofit that can work with any kind of lab, including labs in private institutions. The certification program helps labs evaluate and address their environmental impact, focusing on specific key areas.
Any of UVA’s research laboratories can participate in this program. Using this online certification form, labs are asked to document their sustainable actions and work with the Green Labs Specialist to learn how to make headway in new areas. You can learn more about previously certified labs in this article.

Moore Lab Attends the Freston Conference in Washington, D.C.
After many months of safety precautions due to COVID-19, the Gastroenterology and related organoid community reassembled in early October at the Freston Conference, hosted at the Madison Hotel in wonderful D.C.
Attendee and Moore lab Post-Doc Deiziane Viana was invited to give a presentation on S. typhimurium infection and circadian rhythm, while staff scientist Arabinda Mandal presented in a poster session on isolated Neurospheres and characteristics from the LMMP (longitudinal muscle myenteric plexus).
In their free time, the lab experienced the National Harbor Ferris Wheel (with a sunset), The Smithsonian Natural History Museum, and authentic Sichuan cuisine at Panda Gourmet.
The insights and techniques brought back will add layers of value to the current ‘Organ on a Chip’ method as well as current developing methods for high throughput/high content organoid screening protocols. Thanks to all the members of the community who were responsible for adding this value in their attendance and participation! #Gastrosquad
The Moore Lab is participating in the Shut the sash Challenge!
Did you know an open fume hood can use as much energy as 3.5 homes, but significant savings can be achieved by keeping them closed when not in use?
Join us in this free competition: https://virginia.az1.qualtrics.com/jfe/form/SV_8zYqjyuP32ScBeK
Here is some additional information from UVA Sustainability about the Shut the Sash Challenge!
Shutting your chemical fume hood sash reduces lab occupants’ potential for exposure to harmful chemicals. Additionally, this single action can help limit the loss of conditioned air, therefore yielding significant energy savings; an open chemical fume hood can use as much energy as three and a half homes. For these reasons, the American National Standards Institute and American Industrial Hygiene Association consider it “good work practice” to keep the sash shut when the hood is not in use.
Participating in UVA Sustainability’s annual Shut the Sash competitions each October is great way to remind researchers, old and new, that shutting the sash enhances safety while reducing your carbon footprint. Raffle-winning teams will receive a prize. You can click here to register for the 2022 Shut the Sash Challenge!

Moore Lab Secures Funding to Study SARS-CoV2 Infection in Intestinal Organoids
The Moore Lab was recently awarded funding through the Bill and Melinda Gates Foundation to study enteric infections with SARS-CoV-2, the cause of coronavirus disease-19 (COVID-19). Influenza-like symptoms ranging from mild disease to severe lung injury dominate, yet symptoms occur in multiple other organs, notably the gastrointestinal tract. The virus utilizes the host angiotensin-converting enzyme 2 (ACE2) as its receptor and to understand the tissue tropism of SARS-CoV-2, multiple research groups have recently applied organoid approaches, demonstrating SARS-CoV-2 directly infects capillary, kidney and intestines—highlighting the spread of the virus throughout the body and multisystemic manifestations of illness.
Among the host factors associated with COVID-19, age and nutritional status are among the greatest risk modifiers of clinical outcomes. Importantly, no organoid studies have yet been performed on tissue from donors in low-resource settings, which tend to have both younger populations and a higher prevalence of undernutrition. We propose to leverage a repertoire of small intestinal organoids from undernourished Pakistani children with environmental enteric dysfunction (EED), healthy U.S. children, and healthy adults.
The main goals of the work are to: (1) Understand the impact of SARS-CoV-2 on ACE2 signaling and nicotinamide (NAD) metabolism, (2) Understand the impact of SARS-CoV-2 in enteroids derived from healthy children vs. children with environmental enteric dysfunction (EED) and determine the impact of nutritional deficiency states on enteroid metabolism and SARS-CoV-2 replication, (3) Understand the impact of SARS-CoV-2 in adults vs. young children on intestinal epithelial metabolism and viral replication. Gabe Henson (PhD Student in the Moore Lab) and Brett Moreau (TUMI Data Scientist and BSL3 expert) will partner together to complete these aims.
(Image: Vero E6 cells treated with either media alone (control) or media+SARS-CoV-2 for 48h. Dramatic cell death is observed, with the control cells still alive, attached, and confluent; the virus treated cells have ~50% of cells floating/dying.)

Microbiome directed prevention of parenteral nutrition associated with liver injury in the NICU.

Ajay Kumar, PhD
We are pleased to announce that Dr. Ajay Kumar, helped in a tremendous way, to secure the receipt of funding for the submission to the iTHRIV Pilot Translational and Clinical Studies (PTC) Program and the iTHRIV leadership. The title of his proposal is “Microbiome directed prevention of parenteral nutrition-associated with liver injury in the NICU. Parenteral nutrition (PN) is a lifesaving nutritional intervention in premature infants with delayed tolerance of oral or enteral feeds. PN-associated liver disease or cholestasis (PNAC) is a frequent complication of PN, with high morbidity and associated healthcare costs. Lipid sparing strategies and alternative lipid formulations mitigate the risk and severity of PNAC in the NICU, however, these approaches are often used as reactive countermeasures–once the liver injury has already occurred. The central theme of this proposal is to leverage the microbiome to predict–versus simply react to–PNAC, thereby setting the stage to prevent PNAC in high-risk children. To that end, we propose pilot studies to elucidate the role of the gut microbiome in PNAC and identify microbiome signatures predictive of PNAC. Through an established iTHRIV UVA-Inova collaboration, we have for the first time identified blooms of gram-negative bacteria (Klebsiella, Veillonella, Enterobacter, and Enterococcus) in the stool of 4 sets of premature twins discordant for PNAC. Importantly, clinical NICU infections with gram-negative bacteria are known risk factors for PNAC; however, the ability to predict PNAC based on a subclinical bloom of these bacteria in neonatal stools has not yet been fully explored. Further, no definitive chain of causality between these blooms and PNAC has been established. These knowledge gaps warrant further exploration in both neonates and preclinical models. Hence, our goals are two-fold: 1) Establish a microbiome-based prediction algorithm for PNAC to facilitate early intervention, 2) Determine the degree to which transplantation of PNAC-associated microbiota from infants to germ-free mice confers susceptibility to PNAC. If successful, these pilot studies will provide compelling preliminary data for comprehensive collaborative project proposals between the Departments of Pediatrics at UVa, Inova, Carillion, and VCU and UVA Biomedical Engineering.

Bill & Melinda Gates Foundation Award
Gregory Medlock, MD
Research Associate
Greg was recently awarded a Phase I Grand Challenges Exploration grant from the Bill & Melinda Gates Foundation. Through this $100,000, 18-month award, we will devise an approach to improve the biomanufacturing of gut microbes for use in probiotic formulations. This goal will be met by designing co-cultures (multiple strains grown together) that produce bacterial biomass more efficiently than the monoculture systems traditionally used. To enable the design of these efficient communities, we will experimentally profile the metabolism of 10 gut microbes across many environments to learn what they consume in order to grow and produce as a result of growth. These data will be coupled with algorithms from the computational geometry field to assign the gut microbes to bioreactors that will optimize their metabolic cooperation with other strains. We will test whether these cooperative, engineered communities produce biomass more efficiently than each of the strains grown alone. By pairing computational modeling with data-driven approaches, we hope to create a system for efficiently growing probiotics anywhere in the world that is optimized based on the resources that are available.
