Epidermal growth factor receptor (EGFR) is a protein on the surface of cells that receives signals telling the cell to grow. Mutations in the EGFR gene are known to drive a number of cancers, including non-small cell lung cancer. For patients with common EGFR mutations, known as “classical mutations,” EGFR inhibitor treatments are available and effective. But such targeted therapies have not been developed for patients with atypical mutations, often leaving chemotherapy as the only treatment option.

We are delighted to announce that Damon Runyon-HHMI Fellow Tyler Starr, PhD, of Fred Hutchinson Cancer Research Center, has been named a 2021 STAT Wunderkind. This award, granted annually to “the best early-career researchers in health and medicine in North America,” recognizes Tyler’s exceptional promise in the study of viruses and our immune systems.

Breast cancer is the most common cancer diagnosed in women worldwide, and an estrogen receptor known as ERα plays a critical role in more than 70% of these cancers. In healthy cells, when bound to estrogen, ERα activates a signaling pathway that controls cell growth, proliferation, and survival. In breast cancer, an abnormal variant of ERα sends this pathway into overdrive. For patients with ERα-positive breast cancer, estrogen-blocking hormone therapies like tamoxifen can prolong survival. Up to half of these patients will acquire resistance, however, creating an urgent need for novel treatment strategies targeting ERα.

Myeloproliferative neoplasms (MPNs) are cancers that arise when a mutated blood stem cell begins to produce too many red blood cells, white blood cells, or platelets. A number of mutations can drive MPNs, and studies have demonstrated that different mutations result in different clinical outcomes. For example, between the two most commonly mutated genes, JAK2 and CALRJAK2-mutated MPNs tend to be the more aggressive cancers.

As cancer cells evolve in response to treatment or other environmental pressures, a patient may end up with a highly diverse population of cancer cells circulating throughout their body. In these cases, a single biopsy from the tissue where the cancer originated is not enough to fully understand the cancer’s genome or how best to target it. Liquid biopsies are thus increasingly used to study circulating tumor cells (CTCs) in the blood, with single-cell CTC sequencing emerging as the next step in unraveling the mysteries of disease progression and treatment response.

Sometimes, while investigating one question, scientists learn the answer to an entirely different one. Some of the most significant medical breakthroughs have begun with open-ended curiosity: insulin, for example, was discovered after two German doctors removed a dog’s pancreas in 1890 to better understand its role in digestion.

September 8, 2021

Because cancer cells proliferate at a higher rate than normal cells, they require more energy than normal cells, and thus need to rewire the cell’s energy-producing processes to meet this excessive demand. Think of spoiled Veruca Salt in Charlie and the Chocolate Factory rerouting the chocolate bar supply directly to her father’s factory, where his workers unwrapped them faster than any normal child could, expediting her discovery of a Golden Ticket.

August 27, 2021

One way to determine how successfully a patient’s cancer treatment has eradicated the disease is to check the bloodstream for free-floating DNA originating from tumor cells, also known as circulating tumor DNA (ctDNA). The detection of ctDNA can serve as a powerful prognostic tool, allowing clinicians to assess the effectiveness of treatment and predict the likelihood of disease recurrence.

Pancreatic cancer, which will affect an estimated 60,430 Americans this year, is notoriously hard to treat. Chemotherapy and immunotherapy drugs sometimes work at first, but often the tumors develop resistance and continue to grow. This makes it one of the most lethal types of cancer, with the average five-year survival rate after diagnosis hovering around 10%.

August 23, 2021

A range of genetic disturbances can result in the same type of cancer, the way an off-tasting dish might result from any number of bad ingredients or missteps in the preparation process. Often, variation in clinical features—tumor appearance, location, behavior—is what defines cancer subtypes, while the genetic origins of each subtype remain unclear. But to make sense of this variation, and thus refine diagnosis and develop more precise treatments, researchers must trace these clinical features back to their genetic origins.

August 14, 2021

Clear cell renal cell carcinoma (ccRCC), which accounts for over 75% of kidney cancer diagnoses, gets its name from how the tumor cells look under a microscope. Their clear appearance, as if the tissue were studded with air bubbles, is due to an accumulation of cholesterol in the cells. Studies have shown that ccRCC cells contain at least twice as much cholesterol as normal kidney cells, and in some cases up to 35 times more. How this accumulation occurs and how it contributes to cancer progression, however, is poorly understood.

July 12, 2021

Researchers at Stanford University have discovered sugar-bound RNA strands protruding from the cell surface, challenging the long-held assumption that these two types of molecules are kept separate within the cell. These newfound “glycoRNAs,” identified by former Damon Runyon Fellow Ryan Flynn, MD, PhD, may serve an important role in immune signaling. A shock to biologists across disciplines, this finding has particular significance in the world of cancer research, as the development of effective immunotherapies hinges on our understanding of how the immune system is activated.


July 7, 2021

Immune checkpoint blockades are remarkably effective at exposing tumor cells to immune system attack, but only in the minority of patients with highly mutated tumors. While a high number of genetic mutations may seem like a bad thing, more mutations mean tumors produce more antigens, making them more recognizable to immune T-cells, and thus more susceptible to immunotherapy. In a groundbreaking report, Damon Runyon alumni Robert K. Bradley, PhD, and Omar Abdel-Wahab, MD, offer proof of concept that introducing errors in the short-lived RNA—rather than permanent DNA damage—still causes tumors to present antigens on their cell surface, stimulating immune response. The hope is that drugs that induce such RNA errors could be used in combination with checkpoint blockades to shrink therapy-resistant tumors.

Selection bias occurs when those chosen to participate in a study are not representative of the target population, limiting how much we can trust the study results. In order to quantify this selection bias, researchers have come up with a metric known as the diagnosis-to-treatment interval (DTI), which measures treatment urgency among trial participants. DTI, however, is not an ideal metric for selecting trial participants, as non-biological factors like access to medical care also influence the amount of time between diagnosis and treatment. Finding a biological basis for DTI would offer a more objective measure of clinical urgency, and thus be more useful in mitigating selection bias.


June 21, 2021

After successfully reversing leukemia development in mice and human cell lines, former Damon Runyon-Lilly Clinical Investigator Scott Armstrong, MD, PhD, and his lab at Dana-Farber Cancer Institute are testing a novel therapeutic approach in clinical trials, open to patients as young as one month old. The drug, known as SNDX-5613, is currently being evaluated as a treatment for acute myeloid leukemia (AML), but may one day be used to prevent the cancer from developing in the first place.

June 18, 2021

The American Society of Clinical Oncologists hosted their annual meeting this past weekend (June 4th-8th, 2021), giving oncology professionals from around the globe the chance to present cutting-edge research on new cancer therapies, ongoing clinical trials, and standards of patient care. Among the studies presented were those of several former and current Damon Runyon Clinical Investigators, whose research unites lab inquiry with clinical application.

One of the many ways tumor cells evade capture by the immune system is by presenting proteins on their surface that signal “don’t touch me” to immune T-cells. These proteins are called immune checkpoints. Therapies that block them—known as immune checkpoint blockades (ICB)—are remarkably effective, but they only work for a minority of cancer patients. In search of more widely beneficial immunotherapies, Damon Runyon Physician-Scientist Gabriel Griffin, MD, and colleagues at the Broad Institute of MIT and Harvard are investigating other mechanisms of immune system evasion to target in combination with ICB. Specifically, they have set out to find epigenetic regulators—proteins that turn genes “on” and “off”—that play a role in helping cancer cells avoid detection.

Prostate cancer (PCa), second only to skin cancer in prevalence among American men, has multiple subtypes defined by which key gene was mutated early in disease progression. Molecular analysis of PCa tumors has illuminated these subtype-defining genetic events, yet it remains unclear how these early alterations influence later genetic events and, eventually, result in different clinical outcomes. While molecular characterization often guides treatment decisions in breast and other cancers, more clarity is needed about these pathways for PCa subtyping to be clinically relevant. At Weill Cornell Medicine, Damon Runyon Clinical Investigator Chris Barbieri, MD, PhD, and colleagues are leading this charge.

While some cancers are known to be caused by mutations in key genes, genetic mutation does not always tell the full story. Epigenetic changes—which do not affect the DNA sequence itself, but rather the degree to which a gene is expressed—can play an important role in cancer as well. Such is the case with acute lymphoblastic leukemia (ALL), the most common form of cancer in children, which has a low incidence of genetic mutation but often coincides with abnormal epigenetic behavior.

May 5, 2021

There are two types of genes that, if mutated, can lead to cancer. One set of genes directs cell growth – a mutation in one of these genes can cause cells to grow uncontrollably, like a gas pedal stuck to the car floor. The other set of genes function as the “brakes,” telling cells when to slow down, correct replication mistakes, or undergo apoptosis (programmed cell death). These are called tumor suppressor genes, and as the name implies, a disruption in their function can allow the growth of tumors.

Established by an Act of Congress in 1863, the National Academy of Sciences (NAS) is the body of distinguished researchers “charged with providing independent, objective advice to the nation on matters related to science and technology.” Election to membership is among the highest honors a scientist can receive. This year, three Damon Runyon alumni join the NAS ranks, bringing the total number of Damon Runyon alumni in NAS to 89.


April 28, 2021

By the time patients experience symptoms, their tumors contain a genetically diverse collection of cancer cells, each with an accumulation of mutations. If we could better understand the sequence of events that leads from a single mutation to a heterogeneous population of tumor cells, earlier detection and intervention might be possible. However, attempts to trace this evolution where it has already occurred (in model organisms, immortalized cell lines, or patient samples) face significant challenges.


April 23, 2021

The KRAS gene, responsible for encoding a protein that serves as an “on/off” switch for cell growth, is one of the most commonly mutated genes in cancer. The frequency and nature of its mutation differ across cancer types, however, with the highest occurrence of mutation found in cancers of the colorectum, pancreas, lung, and blood plasma.


April 5, 2021

The tumor, once an indistinct mass of heterogeneous cells, is gaining single-cell resolution. Until recently, even distinguishing between healthy cells and malignant cells within a tumor sample presented a challenge.


March 11, 2021

Nearly all human cancers, and particularly blood cancers, involve dysregulated gene expression – the wrong genes are switched on or the right ones are switched off. The molecule responsible for switching genes on and off is called a transcription factor. Identifying which transcription factor is misbehaving and how is often the key to developing effective cancer treatments.


February 22, 2021

A new study demonstrates the staying power of the immune response generated by a personalized cancer vaccine called NeoVax, which works by targeting specific proteins on each patient’s tumor cells to activate the body's immune system against the cancer.


January 28, 2021

Pancreatic cancer is one of the most difficult forms of cancer to treat effectively. Standard courses of chemotherapy drugs often come up short for patients, leading to a dismal 5-year relative survival rate of just 10%. And while the past few years’ transformative breakthroughs in immunotherapy have drastically improved the prognosis for many patients diagnosed with other forms of cancer, most pancreatic cancers have proved frustratingly resistant to immunotherapy alone.
