Wedekind lab research featured on the cover of JBC “The Year in JBC: 2020" issue

Friday, February 12, 2021

Congratulations to Shashank Chavali, Dr. Sachitanand Mali, Dr. Jermaine Jenkins, Dr. Rudi Fasan, and Dr. Joseph Wedekind for being featured on the cover of JBC “The Year in JBC: 2020" issue. Their recent research article, published in the Journal of Biological Chemistry (JBC) December 4, 2020 issue, titled “Co-crystal structures of HIV TAR RNA bound to lab-evolved proteins show key roles for arginine relevant to the design of cyclic peptide TAR inhibitors” has been selected as the representative ‘RNA’ article for 2020 retrospective collection called “The Year in JBC: 2020.”

The cover art below, shows a collage of fluorescence complementation experiments between the [4Fe-4S]-transferring NFU1 and potential partners (performed by Roland et al.), crystal structure overlays of HIV-1 TAR RNA with lab-evolved TAR-binding proteins (reported by Chavali et al.), nonmelanized yeast cells (explored by Chrissian et al.) and a cryo-EM structure of STEAP1, now thought to function as a ferric reductase in heterotrimer form (reported by Oosterheert and Gros). Artwork created by EJ Marklin.

Lynne Maquat Awarded 2021 Wolf Prize in Medicine

Tuesday, February 9, 2021

Lynne Maquat

 

Lynne E. Maquat, Ph.D., the founding director of the Center for RNA Biology at the University of Rochester, was honored with the 2021 Wolf Prize in Medicine. The acclaimed international award is given to outstanding scientists from around the world for achievements that benefit mankind. 

Maquat was selected for “fundamental discoveries in RNA biology that have the potential to better human lives.” She has spent her career deciphering the many roles that RNA plays in sickness and in health, and is well known for her discovery of nonsense-mediated mRNA decay or NMD. One of the major surveillance systems in the body, NMD protects against mistakes in gene expression that lead to disease. Maquat’s lab also revealed that NMD helps our cells adjust to changes in development and in their environment, and more rapidly respond to certain stimuli.

Maquat shares the award with Joan Steitz, Ph.D., Sterling Professor of Molecular Biophysics and Biochemistry at Yale School of Medicine and Adrian Krainer, Ph.D., St. Giles Foundation Professor and Cancer Center Deputy Director of Research at Cold Spring Harbor Laboratory. Steitz and Krainer were also honored for discoveries in RNA biology.

The Wolf Foundation, which celebrates exceptional achievements in the sciences and the arts, is based in Israel, where Maquat’s quest to unravel the intricacies of NMD began. In 1980 she traveled to Jerusalem to retrieve bone marrow samples from four children suffering from thalassemia major, the most severe form of the inherited blood disorder thalassemia. Maquat wanted to learn why the children’s marrow contained no beta-globin protein, which is necessary for the oxygen-carrying function of red blood cells. Her 1981 breakthrough manuscript, “Unstable beta-globin mRNA in mRNA-deficient beta0 thalassemia,” published in Cell, was the first to reveal the role of NMD in human cells and how it can lead to disease.

“Lynne’s work on nonsense-mediated mRNA decay is the bedrock of an ever-growing body of research on how mRNAs are monitored and regulated,” said Mark B. Taubman, M.D., dean of the University of Rochester School of Medicine and Dentistry. “Her dedication to her science and to the field of RNA biology has opened the door to the development of RNA-based therapeutics for a wide range of disorders that you can’t reach with conventional drugs. We’re thrilled that her contributions are being recognized with this prestigious award.”

RNA secured its place in the public eye in 2020 with the development and approval of multiple mRNA COVID-19 vaccines. Years of research by Maquat, Steitz and Krainer helped set the stage for the rapid development of these vaccines.

The J. Lowell Orbison Endowed Chair and Professor in the Department of Biochemistry and Biophysics at the University of Rochester School of Medicine and Dentistry, Maquat is the recipient of several other significant honors, including:

Winners of the Wolf Prize are selected annually by an international jury committee of the Wolf Foundation; prizes are awarded regardless of religion, gender, race, geographical region, or political view. The official announcement of this year’s prize by the President of the State of Israel, Reuven Rivlin, was made on February 9, 2021.

Beneath the Surface of Fragile X Syndrome: Study Sheds Light on What’s Happening in Nerve Cells

Monday, January 25, 2021

A new study shows that many abnormalities in fragile X syndrome cells are related to glitches with one of the body’s major quality control systems. Published in Nature Cell Biology, the research provides fresh insight into the molecular mechanisms of the disorder and a pathway to search for potential treatments.

Fragile X syndrome occurs when individuals don’t make the fragile X protein known as FMRP, which is needed for normal brain development. Currently, little is known about how the loss of this crucial protein leads to the intellectual disability and severe learning problems characteristic of the disease.

Rochester researchers found that many irregularities in cells that lack FMRP are due to misregulated nonsense-mediated mRNA decay, or NMD. Discovered by RNA biologist Lynne E. Maquat, Ph.D., NMD is like a molecular guide that helps our cells make smart decisions that (in most cases) improve cellular function and contribute to good health. For example, NMD helps our cells adjust to changes in development and in their environment, and more rapidly respond to certain stimuli.

Through a series of cellular analyses, Maquat’s team discovered that NMD influences a wide range of genes throughout the brain, including genes that govern motor control and cognitive processes related to attention, learning and language. They also found that when FMRP is absent from cells, as it is in people with fragile X syndrome, nonsense-mediated mRNA decay shifts into overdrive.

New Research Funding Initiative to Support Young Investigators

Friday, January 15, 2021

Thanks to a partnership between pediatric researchers and the GCH Advancement division, a new funding initiative will seek to provide $25,000 – matched with grant funds – to support individual young investigators who are undertaking pediatric research.

These young investigators would be tenure-track assistant professors or post-doctoral fellows who already have a PhD degree and are on the path to obtain a tenure track position. This type of “seed” funding will be critical for fostering the careers of young researchers at URMC and could potentially pay dividends for institutional growth in the long-term, according Tom Mariani, PhD, professor of Neonatology and director of research for the Department of Pediatrics.

“In addition to funding discovery and innovation which could potentially save millions of lives, the career development of one investigator can be leveraged many times over to merit additional external funding, creation of new labs, and stimulate economic growth in the Rochester community.”

Alan Wood, owner of the Realty company RE/Max Plus and supporter of GCH, and Lynne Maquat, PhD, endowed chair and professor in the Departments of Biochemistry and Biophysics, Oncology, and Pediatrics, developing this funding idea after Wood and his children visited Maquat’s Fragile X Syndrome lab this Fall. Fragile X Syndrome is the most common single-gene cause of autism and intellectual disability, and Wood’s family got a thorough education on the scope of Maquat’s work, which is examining disease-causing mutations in children, and what those mutations do to gene expression via RNA production.

“My children loved getting first-hand experience touring the lab and seeing real-world visualizations of the work Maquat and her team are doing. Wearing lab coats and gloves, they isolated genetic material from bananas, which turn out to have more genetic material than us humans,” said Wood.

Wood will be leading the effort to develop the program and secure funding. Donors who sponsor a young investigator will be able to establish a relationship to learn more about their research as it evolves.

“We have several talented young researchers in the Department of Pediatrics,” said Maquat, “providing early support for their career is a long-term goal. The results won’t be immediate, but over time, this support will build the foundation for discovery that will improve kids’ lives.”
