Pancreatic cancer cells operate a recycling program that would be the envy of any municipality — but the only beneficiaries are the cells themselves. All cells in the body recycle minerals and nutrients, removing them from storage and breaking them down them for re-use. But in cancer cells, this process, known as autophagy — literally, … Read more
To understand the genesis of the bone marrow transplant field, go back to the detonation, in 1945, of the first nuclear weapons and the shadow of the Atomic Age. The search for ways to rescue the blood-forming and immune systems of individuals exposed to high doses of radiation provided the impetus for donor bone marrow … Read more
Logic said that drugs known as PARP inhibitors would work as well — and perhaps even better — in breast cancer marked by BRCA gene mutations than in ovarian cancer carrying the same abnormalities. Clinical results said otherwise. Patients with relapsed, BRCA-mutated ovarian cancer survive longer, overall, with PARP inhibitor treatment than any other therapy. … Read more
An exercise-related hormone, irisin, administered to animals with a model of Parkinson’s disease reduced nerve degeneration and symptoms associated with the progressive movement disorder, say scientists from Dana-Farber and Johns Hopkins Medicine. About one million people in the United States, and 10 million people worldwide are living with Parkinson’s, which is characterized by tremors, slowed … Read more
Of all the mutated, blundering, havoc-wreaking genes in cancer cells, few are more ubiquitous than TP53. The gene, which in its normal, capable form is nicknamed the “guardian of the genome,” is found in a flawed form in almost every type of cancer, including up to half of all lung, ovarian, and colorectal cancers and … Read more
Discovered only about a decade ago, a key actor in the immune system called STING has become a hot target of research aimed at improving cancer immunotherapy. STING (stimulator of interferon genes) has been called a “master regulator” of the innate immune response against cancer. When activated by substances called agonists, STING turns on genes … Read more
Technically speaking, a tyrosine kinase is an enzyme that transfers a compound called a phosphate group from ATP — a molecule that stores energy — to a specific area on cell proteins. It helps transmit the signals that cause cells to grow and divide and to perform specific functions in the body such as burning … Read more
Two major obstacles once stood in the way of exploring the basic biology of diffuse midline glioma in children. And one of them was the brain itself. The cancer, a subtype of high-grade glioma, forms in some of the most critical parts of the brain, in regions that control such basic functions as breathing, swallowing, … Read more
With its deep experience in studying the rare, often lethal cancer known as NUT carcinoma, Dana-Farber Brigham Cancer Center attracts patients and families, some from far away. Unfortunately, NUT carcinoma is so rapidly aggressive that “sometimes patients get to Dana-Farber and become too sick to proceed with treatment,” which speaks to the urgent need for … Read more
Like a fugitive from justice, cancer cells stake their survival on their ability to remain inconspicuous. In many cases, however, they are decked out in molecules – called tumor-associated antigens and neoantigens – that shout “cancer!” to the immune system and prompt a potent antitumor response. But tumor cells have other means of dodging an … Read more
The results of the phase 2 clinical trial would have been impressive even if they didn’t involve a particularly stubborn form of cancer. In the trial, led by Dana-Farber’s Jonathan Schoenfeld, MD, MPH, 29 patients with locally advanced squamous cell cancer of the oral cavity were treated with one or two immune checkpoint inhibitors — … Read more
Picture a floor strewn with broken crockery, hastily and haphazardly pieced back together, and you’ll have a sense of the chromosomal chaos inside many cancer cells. In a phenomenon known as chromothripsis, a chromosome or piece of chromosome shatters and reassembles almost randomly, mangling its genetic information. It’s a common feature of cancer cells, found … Read more
While some racial and ethnic groups have been underrepresented in clinical trials of therapies for lung cancer, breast cancer and other malignancies, researchers speculated that the situation might be different for adult leukemia trials. The unique features of the disease — the speed with which it needs to be treated after diagnosis, the delivery of … Read more
Even as science has removed all doubt about the link between environmental factors like tobacco smoke and lung cancer, the role of genetics in people’s risk of the disease has been much harder to pin down. A study by Dana-Farber investigators provides new evidence that, in people with lung cancer, genetic ancestry can influence the … Read more
In an era when targeted therapies are often effective against multiple types of cancer, the U.S. Food and Drug Administration’s accelerated approval of a two-drug therapy for solid tumors carrying a specific mutation in the BRAF gene is a prime example of this trend. For patients with glioma brain cancer that harbors the mutation, the … Read more
Scientists are stepping up efforts to deploy natural killer (NK) cells — the body’s first responders against infected and malignant cells — to combat cancer. Treatment using NK cells from healthy donors has shown promise, but currently successes have been limited and the cells lack staying power in the body. While some researchers are working … Read more
CAR T cells’ superpower is to identify cancer-related targets on the surface of tumor cells and order an attack on those cells. But they lack anything resembling X-ray vision to detect nefarious protein targets within tumor cells. That shortfall has limited their effectiveness in diseases like acute myelogenous leukemia (AML), in which tumor cells display few surface … Read more
For many years, the human genome was viewed as a book of life in which sections of great eloquence and economy of expression were interspersed with vast stretches of gibberish. The legible sections contained the code for making cell proteins; the other regions, representing about 90% of the entire genome, were dismissed as “junk DNA,” … Read more
Results of several phase 3 trials and dozens of other studies led by Dana-Farber researchers were presented online and in person June 3-7 at the 2022 Annual Meeting of the American Society of Clinical Oncology (ASCO), the world’s largest clinical cancer research meeting. Some of the research reports presented by Dana-Farber investigators include: Improved progression-free … Read more
The cells in our body replicate themselves in a tightly regulated series of steps and molecular checkpoints that act as gatekeepers. A set of proteins called cell cycle kinases, including CDK1, CDK4, and CDK6, control various phases and timing of the process so that cells divide and replicate only when needed, and under strict control. … Read more
