Nobel Laureate Carolyn R. Bertozzi, PhD, to receive 2023 AACR Award for Outstanding Achievement in Chemistry in Cancer Research

2023-03-15
(Press-News.org) PHILADELPHIA – The American Association for Cancer Research (AACR) will honor Nobel Laureate Carolyn R. Bertozzi, PhD, with the 2023 AACR Award for Outstanding Achievement in Chemistry in Cancer Research during the AACR Annual Meeting 2023, April 14-19 in Orlando, Florida.

Bertozzi is the Anne T. and Robert M. Bass Professor of Chemistry in the School of Humanities and Sciences and a professor (by courtesy) of chemical and systems biology and of radiology at Stanford University, an investigator with the Howard Hughes Medical Institute, and the Baker Family Director of Sarafan ChEM-H. Bertozzi is being recognized for advancing basic and translational cancer research through bioorthogonal chemistry and chemical glycobiology.

The AACR Award for Outstanding Achievement in Chemistry in Cancer Research was established by the AACR and its Chemistry in Cancer Research Working Group in 2007 through the support of GlaxoSmithKline to recognize the importance of chemistry to advancements in cancer research. The award recognizes outstanding, novel, and significant chemistry research that has led to important contributions in basic cancer research; translational cancer research; cancer diagnosis; the prevention of cancer; or the treatment of patients with cancer. Such research may include, but is not limited to, chemical aspects of carcinogenesis; chemical biology; drug discovery and design; imaging agents and radiotherapeutics; metabolomics and mass spectrometry; proteomics; and structural biology.

Bertozzi is credited with inventing the field of bioorthogonal chemistry, which has enabled the development of numerous experimental approaches in biological research, including innovative imaging methods, chemoproteomics, and in vivo drug targeting. Historically, chemical reaction conditions have been difficult to control in living cells. To overcome this challenge, Bertozzi hypothesized that chemical reactions could be specifically designed to occur in living organisms by carefully selecting reaction partners instead of attempting to manipulate reaction conditions. Her early research was focused on combining metabolic labeling with bioorthogonal chemistry, demonstrating that this approach allowed for targeted interrogations of biological systems. This fundamental advancement sparked a revolution in the manipulation and understanding of biological systems. However, this method often resulted in off-target reactions in cellular environments with ketone and aldehyde groups. In turn, Bertozzi developed a modified technique that avoided such issues. Now known as copper-free click chemistry, this technology is widely used by researchers worldwide for drug discovery and therapeutic development efforts.

Further advancements by Bertozzi to biorthogonal chemistry approaches have enabled large-scale production of highly stable antibody-drug conjugates, a class of therapeutics being utilized for the treatment of cancer. Advancements to this technology have led to the clinical testing of TRPH-222, a CD22-targeting antibody-drug conjugate for relapsed and refractory B-cell lymphoma. Bertozzi’s inventions have also led to the establishment of site-specific protein modification technologies, which are now used for the clinical development of antibody-drug conjugates and the preclinical development of antibody-enzyme conjugates for cancer immunotherapy.

In addition to her click chemistry work, Bertozzi discovered that tumor-associated glycans promote immunosuppression by engaging Siglec receptors on immune cells. She has been heralded for engineering antibody-sialidase conjugates, which represent a new class of therapeutically relevant molecules for the selective cleaving of immunosuppressive glycans from tumor cell surfaces. Since Siglec receptors are found on multiple types of immune cells, this strategy has the unique potential to unleash stronger antitumor immune responses than first-generation immunotherapies. Underscoring the translational impacts of this work, an antibody-sialidase conjugate is currently being evaluated in phase I clinical trials.

In addition to receiving the 2022 Nobel Prize in Chemistry, Bertozzi has been honored with numerous awards throughout her brilliant career, including the Welch Award in Chemistry (2022), the University of Pittsburgh Dickson Prize in Medicine (2022), the Dr. H.P. Heineken Prize for Biochemistry and Biophysics (2022), the Wolf Prize in Chemistry (2022), the American Association for the Advancement of Science Lifetime Mentor Award (2022), the Wistar Institute Helen Dean King Award (2022), STAT News STATUS List (2022), the Society for Glycobiology President’s Innovator Award (2020), the Nagoya Medal (2020), the Chemistry for the Future Solvay Prize (2020), the National Academy of Sciences John J.

Study offers a potential strategy to improve T cell therapy in solid tumors

2023-03-15
PHILADELPHIA – A new approach that delivers a “one-two punch” to help T cells attack solid tumors is the focus of a preclinical study by researchers from the Perelman School of Medicine at the University of Pennsylvania. The findings, published in the Proceedings of the National Academy of Sciences (PNAS), showed that targeting two regulators that control gene functions related to inflammation led to at least 10 times greater T cell expansion in models, resulting in increased antitumor immune activity and durability. CAR T cell therapy was pioneered at Penn Medicine by ...

Uncovering the ritual past of an ancient stone monument in Saudi Arabia
2023-03-15
A comprehensive analysis of an archaeological site in Saudi Arabia sheds new light on mustatils—stone monuments from the Late Neolithic period thought to have been used for ritual purposes. Melissa Kennedy of the University of Western Australia, Perth, and colleagues, in conjunction with The Royal Commission for AlUla present these findings in the open-access journal PLOS ONE on March 15, 2023. Built around 7,000 years ago, mustatils are rectangular, low-walled, stone structures that range from 20 to 600 meters in length. Researchers first discovered them in the 1970s, and more than 1,600 mustatils have now been discovered, primarily concentrated in northern ...

Estrogen possible risk factor in disturbed heart rhythm

Estrogen possible risk factor in disturbed heart rhythm
2023-03-15
The sex hormone estrogen has a negative impact on heartbeat regulation, according to an experimental study from Linköping University, Sweden, published in Science Advances. Estrogen impact seems to interact with hereditary changes causing a heart disease disturbing the heart’s rhythm, while other endogenous substances may have a protecting effect. In a lifetime, the heart beats around 2.5 billion times. Each heartbeat is triggered by an electrical impulse that causes the heart muscle to contract in a very well-coordinated movement. ...

Radar images record potential volcanic activity on Venus

2023-03-15
Researchers have identified evidence they interpret as active volcanism on the surface of Venus, according to a new analysis of radar images from the Magellan spacecraft. The images reveal a vent that changed shape on Venus, which they believe points to ongoing volcanic activity there. Many volcanoes have been identified on the surface of Venus, but evidence of recent volcanic activity on the planet has been lacking. As a result, it was unknown whether the prominent volcanic features of Venus’ geologically young surface are a product of ongoing active volcanism ...

Resilient bug-sized robots keep flying even after wing damage

Resilient bug-sized robots keep flying even after wing damage
2023-03-15
Bumblebees are clumsy fliers. It is estimated that a foraging bee bumps into a flower about once per second, which damages its wings over time. Yet despite having many tiny rips or holes in their wings, bumblebees can still fly. Aerial robots, on the other hand, are not so resilient. Poke holes in the robot’s wing motors or chop off part of its propellor, and odds are pretty good it will be grounded. Inspired by the hardiness of bumblebees, MIT researchers have developed repair techniques that enable a bug-sized aerial robot to sustain severe damage to the actuators, or artificial muscles, that power its wings — but to still fly effectively. They optimized these artificial muscles ...
