John Lueck

Joanne Ladolcetta, a freelance writer based out of San Francisco, wanted to put together information to help address circulating fears and misconceptions about the recently FDA approved COVID-19 mRNA vaccines. She reached out to friends Bryant Johnson (Cartoonist) and John Lueck (Researcher at the University of Rochester Medical Center) to tackle some of the most common vaccine questions. The collaboration resulted in an approachable informative write-up with creative illustrations and helpful links to provide readers the ability to do a deeper dive into the generation and application of the novel COVID-19 mRNA vaccines.

The US Food and Drug Administration recently approved emergency use authorization for a COVID-19 vaccine developed by Pfizer and the German pharmaceutical company BioNTech.

The vaccine made history not only because it reported a 95 percent efficacy rate at preventing COVID-19 in clinical trials, but because it is the first vaccine ever approved by the FDA for human use that is based on RNA technology.

"The development of RNA vaccines is a great boon to the future of treating infectious diseases," says Lynne Maquat, the J. Lowell Orbison Distinguished Service Alumni Professor in biochemistry and biophysics, oncology, and pediatrics at Rochester and the director of Rochester's Center for RNA Biology.

COVID-19, short for "coronavirus disease 2019," is caused by the novel coronavirus SARS-CoV-2. Like many other viruses, SARS-CoV-2 is an RNA virus. This means that, unlike in humans and other mammals, the genetic material for SARS-CoV-2 is encoded in ribonucleic acid (RNA). The viral RNA is sneaky: its features cause the protein synthesis machinery in humans to mistake it for RNA produced by our own DNA.

For that reason, several of the leading COVID-19 vaccines and treatments are based on RNA technology.

A contingent of researchers at the University of Rochester study the RNA of viruses to better understand how RNAs work and how they are involved in diseases. This RNA research provides an important foundation for developing vaccines and other drugs and therapeutics to disrupt the virus and stop infections.

"Understanding RNA structure and function helps us understand how to throw a therapeutic wrench into what the COVID-19 RNA does—make new virus that can infect more of our cells and also the cells of other human beings," Maquat says.

In the past few decades, as scientists came to realize that genetic material is largely regulated by the RNA it encodes, that most of our DNA produces RNA, and that RNA is not only a target but also a tool for disease therapies, "the RNA research world has exploded," Maquat says. "The University of Rochester understood this."

In 2007, Maquat founded The Center for RNA Biology as a means of conducting interdisciplinary research in the function, structure, and processing of RNAs. The Center involves researchers from both the River Campus and the Medical Center, combining expertise in biology, chemistry, engineering, neurology, and pharmacology.

With the recent acquisition of Nobel Prize-winning technology and two new grants, Wilmot Cancer Institute researchers are streamlining their investigations into a malignant blood disease known as MDS, working toward discovering targeted therapies.

Laura Calvi, M.D., and Clara Kielkopf, Ph.D., are leading collaborative teams that will be using a device at the University of Rochester Medical Center — a cryo-electron microscope — that has ushered in a new era in biochemistry. The microscope allows scientists to see 3D snapshots and more details of living molecules than ever before, down to near-atomic resolution, to understand disease and uncover new ways to design drugs. The developers of the technology were awarded the Nobel Prize in Chemistry 2017.

Calvi and Kielkopf each received Edward P. Evans Foundation awards totaling $1.2 million for this project. Evans grants go to scientists seeking a cure for myelodysplastic syndromes (MDS), which originates in the bone marrow and disrupts healthy blood cell formation. MDS often leads to leukemia.

The Kielkopf lab will use the cryo-electron microscope to obtain 3D views of recurrent MDS mutations as guides for targeting molecular therapies. The modern microscope is the first of its kind in the Rochester region, Kielkopf said, and will be accessible to all UR researchers through the Electron Microscopy Shared Resource Laboratory. She is a professor of Biochemistry and Biophysics in the Center for RNA Biology.

We are thrilled to announce that Professor David Mathews, MD, PhD, was honored at this year's School of Medicine Opening Convocation by being installed as the first Lynne Maquat Distinguished Professor in RNA Biology in the School of Medicine and Dentistry. The professorship was awarded by Dr. Mark Taubman, Dean of the School of Medicine and CEO of the University of Rochester Medical Center. The Convocation was held virtually this year and can be viewed at the link below.

Prof. Clara Kielkopf has been awarded an EvansMDS research grant to use the new, state-of-the-art cryo-electron microscope at the U of R Medical Center EM facility. The Kielkopf group will use this revolutionary technique to study 3D structures of mutant U2AF1-splicing complexes in human malignancies. The title of the EvansMDS grant is: "Cryo-Electron Microscopy Structures of Mutant U2AF1-Containing Ribonucleoproteins Associated with Myelodysplastic Syndromes". This grant was made possible by our new Talos cryo-EM.

This week's URMC Research Heroes featured the Maquat lab's Tatsuaki Kurosaki, PhD, and Shuhei Mitsutomi, MS, who were recognized today for their work on SARS-CoV-2.

Both Tatsuaki and Shuhei have worked as members of the Maquat Lab (Center for RNA Biology and the Department of Biochemistry & Biophysics) during the sequestration on SARS-CoV-2, collaborating with a lab at Harvard to determine the mechanism by which the virus inhibits human-cell nonsense-mediated mRNA decay (NMD) so as to express and replicate its RNA efficiency.

From Tatsuaki: "Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes the coronavirus disease 19 (COVID-19) pandemic, is a novel enveloped RNA virus carrying a large (~30 kb) positive-sense single-stranded RNA genome. Although human cells innately have an RNA surveillance pathway called nonsense-mediated mRNA decay (NMD) that generally protects cells from infection by many different types of viruses, little is known about how SARS-CoV-2 inhibits NMD to proliferate in human cells. We hope that our research helps to elucidate the molecular mechanisms of SARS-CoV-2 proliferation in human cells, eventually contributing toward the development of therapeutic strategies to combat COVID-19."

Viruses like the coronavirus that causes COVID-19 are able to unleash their fury because of a devious weapon: ribonucleic acid, also known as RNA.

A contingent of researchers at the University of Rochester study the RNA of viruses to better understand how RNAs work and how they are involved in diseases. As COVID-19 continues to spread around the globe, RNA research provides an important foundation for developing antiviral drugs, vaccines, and other therapeutics to disrupt the virus and stop infections.

"Understanding RNA structure and function helps us understand how to throw a therapeutic wrench into what the COVID-19 RNA does—make new virus that can infect more of our cells and also the cells of other human beings," says Lynne Maquat, professor of biochemistry and biophysics at the University of Rochester Medical Center and the director of Rochester's Center for RNA Biology.

In the past few decades, as scientists came to realize that genetic material is largely regulated by the RNA it encodes, that most of our DNA produces RNA, and that RNA is not only a target but also a tool for disease therapies, "the RNA research world has exploded," Maquat says. "The University of Rochester understood this."

In 2007, Maquat founded the Center for RNA Biology as a means of conducting interdisciplinary research in the function, structure, and processing of RNAs. The center involves researchers from both the River Campus and the Medical Center, combining expertise in biology, chemistry, engineering, neurology, and pharmacology.

While much of the research across the University has been put on pause, labs that are involved in coronavirus research remain active.

"Our strength as a university is our diversity of research expertise, combined with our highly collaborative nature," says Dragony Fu, an assistant professor of biology on the River Campus and a member of the Center for RNA Biology. "We are surrounded by outstanding researchers who enhance our understanding of RNA biology, and a medical center that provides a translational aspect where the knowledge gained from RNA biology can be applied for therapeutics."
