New Discoveries and Honors

A tissue biopsy, in which a section of skin is surgically removed for microscopic evaluation, has long been the most effective means of diagnosing skin cancer. But biopsies are invasive and time-consuming procedures, with patients often waiting days for results, developing scars, or forgoing biopsy altogether and opting to “wait and see.” Given that one in five Americans will develop skin cancer in their lifetime, this is a dilemma many of us have experienced firsthand.

Immunotherapies to treat pancreatic cancer—a disease with a nearly 90 percent mortality rate—have been the subject of intensive research efforts in recent years, largely because they have succeeded where other treatment approaches have failed. New developments in mRNA vaccines, immune-enhancing therapies, and combination immunotherapy-chemotherapy regimens have marked a new era in pancreatic cancer treatment. But still, for many patients, nothing seems to work.

Just as the study of a growing plant or animal must take into account its environment, cancer researchers must look beyond a tumor to understand how the surrounding tissue impacts its development. In the case of gliomas, the most common and aggressive type of brain tumor, this means looking at neurons—what signals they emit, and how these signals may play a role in brain tumor progression.  

Renal cell carcinoma ranks among the top ten most common cancers globally, with the clear cell subtype (ccRCC) accounting for the majority of metastatic cases. While some ccRCC tumors respond to immunotherapy treatment, it is often difficult to predict which patients will benefit.

Only about one percent of the human genome contains what we recognize as protein-coding genes: DNA sequences that are transcribed into RNA sequences and then translated into proteins. Much of the intervening space between genes consists of mobile DNA sequences, known as transposable elements, which have the ability to “copy and paste” themselves throughout the genome.

Metastatic pancreatic cancer is often resistant to chemotherapy-based treatments, and clinicians do not currently have a good way to predict whether a patient’s cancer will respond or not. At the Abramson Cancer Center of the University of Pennsylvania, former Damon Runyon-Rachleff Innovator Gregory L. Beatty, MD, PhD, and his colleagues are seeking to uncover the factors that determine response so that patients and clinicians can make better informed treatment decisions.
