How Wafik El-Deiry's Revolutionary Discoveries Earned the Prestigious Kuwait Prize
In the relentless battle against cancer, a disease that claims millions of lives annually, rare moments of breakthrough discovery fundamentally alter our understanding and approach to treatment.
One such transformative moment occurred when Dr. Wafik El-Deiry, then a young researcher at Johns Hopkins University, made a discovery that would forever change how scientists view the body's innate defense mechanisms against cancer. For his groundbreaking work elucidating critical pathways that suppress tumor growth, Dr. El-Deiry was awarded the 2009 Kuwait Prize in Applied Sciences for "Cancer Diseases"—one of the highest honors in the scientific community recognizing exceptional contributions to medical research 1 5 .
This prestigious award, sometimes called the "Arab Nobel Prize," recognizes Dr. El-Deiry's seminal discoveries regarding the p53 tumor suppressor protein and its far-reaching effects on cancer cell behavior. His work not only unveiled fundamental mechanisms by which our bodies fight cancer but also paved the way for entirely new classes of cancer therapeutics 2 7 .

At the heart of Dr. El-Deiry's award-winning work lies a protein known as p53, often called "the guardian of the genome." This remarkable protein acts as a master regulator within our cells, constantly monitoring for DNA damage and preventing mutated cells from multiplying.
Before Dr. El-Deiry's crucial contributions, scientists understood that p53 was important in preventing cancer—mutations in the p53 gene are found in nearly half of all human cancers—but they didn't fully understand how it worked at a molecular level.
This breakthrough identification of p53's binding sequence opened the floodgates for cancer research, allowing scientists to identify numerous genes that are directly controlled by p53 and that execute its tumor-suppressing functions. Among the most important of these genes would be discovered just one year later—a gene called p21 that would provide a critical missing link in our understanding of how cells respond to damage.
In 1993, building on his previous discovery of p53's binding site, Dr. El-Deiry made what many consider his most significant contribution to cancer biology: the identification of p21 (WAF1) as a direct target of p53 and a central regulator of cell cycle progression 1 2 .
The experimental approach that led to this discovery exemplifies scientific ingenuity:
The paper announcing the p21 discovery, published in the journal Cell, would become one of the most highly cited original research articles ever published in that prestigious journal 1 .
p21 was the first cyclin-dependent kinase inhibitor discovered in mammals, opening an entirely new field of study.
The results of these experiments were nothing short of revolutionary. Dr. El-Deiry and his team demonstrated that when p53 detects DNA damage, it activates the p21 gene, producing p21 protein that then slams the brakes on the cell cycle by inhibiting CDKs 2 7 .
The significance of this discovery cannot be overstated. It revealed a key mechanism by which conventional cancer therapies like chemotherapy and radiation work—by causing DNA damage that activates the p53-p21 pathway, ultimately stopping cancer cells from dividing.

While the discovery of p21 was monumental, Dr. El-Deiry didn't stop there. In 1997, he made another crucial discovery that would further expand our understanding of how p53 protects against cancer—this time connecting it to our immune system's ability to eliminate cancerous cells.
His laboratory identified TRAIL Death Receptor 5 (DR5) as another direct target of p53 1 7 . This receptor sits on the surface of cells and, when activated by immune cells, triggers a self-destruct program (apoptosis).
Dr. El-Deiry's work showed that when cells experience DNA damage, p53 not only activates p21 to halt cell division but also increases DR5 on the cell surface, essentially marking damaged cells for destruction by immune cells called natural killer cells 3 .
This discovery had important therapeutic implications. Dr. El-Deiry and others recognized that activating the DR5 pathway could potentially be harnessed as a cancer treatment. His subsequent work focused on understanding how to leverage this discovery for patient benefit, including developing compounds that could activate this death pathway specifically in cancer cells 1 3 .
Discovery of TRAIL receptor DR5 as p53 target created a crucial link between DNA damage response and immune surveillance of cancer.
The true impact of basic scientific research is measured not only by its advancement of knowledge but also by its ability to improve human health.
Dr. El-Deiry's work exemplifies this translation from laboratory discovery to clinical application. His identification of the p53-DR5 connection led him to search for compounds that could activate this pathway to treat cancer.
In 2007, Dr. El-Deiry's laboratory conducted a functional cell-based phenotypic drug screen that identified a small molecule called TIC10 (later renamed ONC201) that potently activated the TRAIL pathway and showed efficacy against multiple cancer types in animal models 3 6 .
The development of ONC201 (now called dordaviprone) represents a classic example of how basic research can lead to unexpected clinical breakthroughs. When ONC201 entered clinical trials in 2014, it showed remarkable effectiveness in a subset of patients with diffuse midline gliomas carrying H3K27M mutations—a particularly aggressive form of brain cancer 3 .

The Kuwait Prize in Applied Sciences recognized not just a single discovery but the cumulative impact of Dr. El-Deiry's work on our understanding and treatment of cancer diseases. His discoveries have fundamentally shaped modern cancer biology and therapy development, with implications that continue to unfold today.
Beyond his specific discoveries, Dr. El-Deiry has made substantial contributions to the scientific community through his leadership roles. He has served as:
Throughout his career, Dr. El-Deiry has maintained a dual role as both laboratory scientist and practicing oncologist, specializing in colorectal cancer treatment 1 5 . This unique perspective has allowed him to directly appreciate the challenges faced by cancer patients while working to develop new solutions through basic research.
Wafik El-Deiry's journey from deciphering the fundamental language of p53 to developing new therapies for cancer patients exemplifies the incredible potential of basic scientific research to transform medicine. His work reminds us that today's "impractical" basic research often becomes tomorrow's life-saving therapy.
The Kuwait Prize in Applied Sciences rightly recognizes not only the individual achievements of an exceptional scientist but also the broader value of supporting fundamental scientific inquiry. As Dr. El-Deiry's career demonstrates, investing in basic research—the kind that seeks to understand biological processes at their most fundamental level—pays dividends far beyond what can be predicted at the outset.
As we continue to face the challenges of cancer, with over 2 million new cases and 600,000 deaths expected in the US in 2025 alone 3 , the need for continued innovation has never been greater. The legacy of Dr. El-Deiry's work serves as both an inspiration and a reminder that supporting basic scientific research remains our most powerful strategy in the ongoing fight against cancer.
