HIV infecting healthy cell

Unlocking the key to HIV persistence

Dec 2, 2019

Even though antiretroviral therapies have allowed many people to live long lives, ridding the body of HIV completely has been an elusive goal ever since the discovery in the 1980s that HIV causes AIDS. New research from the Center for Cancer Research shows that proviral DNA sequences and their integration at specific sites could provide clues for researchers developing drugs to eradicate AIDS.  Read more...

Mitochondrial shape in pancreatic cancer

Computational analysis leads to potential new drug combination for pancreatic cancer

Nov 20, 2019

A computer analysis has been able to predict that low levels of asparagine, an amino acid required for protein synthesis, combined with the shutdown of a stress response pathway can lead to reductions in the fitness of a tumor. These combined findings could potentially lead to new combination therapies to treat aggressive tumors, such as those found in pancreatic cancers. Read more...

Diversity of liver cancer cells can impede tumors’ response to immunotherapy

Oct 3, 2019

New research from the NCI’s Center for Cancer Research shows that understanding the impacts of cellular diversity on liver tumors’ microenvironment suggests ways to make immunotherapy effective for more patients.   Read more...

Advanced imaging technology reveals pulsed hormone release regulates gene transcription

Sep 19, 2019

Using advanced microscopic imaging technology, CCR investigators have correlated a pulsed pattern of hormone release with bursts of transcription, the process in which the genetic information encoded by DNA is written into RNA. They are the first researchers to observe this process at a gene-specific level. Read more...

3D structure of a melanoma cell

Tumor composition of melanoma indicates potential responses to immunotherapy

Sep 13, 2019

The number of genetic mutations in a tumor is thought to influence how well melanoma may respond to immunotherapy, but new research in mice and supported by preliminary human data reveals that the diversity of mutations within a tumor may be a better indicator of response to therapy. Read more...

FDA grants breakthrough therapy designation for new CAR T-cell therapy for B-cell acute lymphoblastic leukemia

Sep 10, 2019

In August 2019, the U.S. Food and Drug Administration granted breakthrough therapy designation to an experimental immunotherapy being developed in the Center for Cancer Research (CCR) for the treatment of B-cell acute lymphoblastic leukemia (ALL), a type of blood cancer. The designation will advance CCR’s development and testing of an immunotherapy for children and young adults whose B-cell ALL is resistant to CD19-targeted immunotherapies.  Read more...

Contour maps created from glucose and lactate signals

Researchers develop a new imaging technique to measure cancer metabolism

Sep 3, 2019

CCR researchers have developed a new technique to show metabolism from MRI images by reducing the amount of noise in those images, resulting in significantly improved quality. This breakthrough enables researchers to see biochemical processes, paving the way for a deeper understanding of tumors and potentially improved diagnosis and treatment. Read more...

Human breast tumor cells arrested in the blood vessels of zebrafish larvae

Tumor cells in transparent fish reveal physical and molecular factors that determine metastasis sites

Aug 21, 2019

CCR researchers used zebrafish to discover that particular sites colonized by migrating tumor cells are determined by both the physical architecture of tissue and the cells’ molecular compatibility with their microenvironment. Read more...

Cervical cancer cells

FDA grants breakthrough therapy designation of new TIL therapy for advanced cervical cancer

Aug 16, 2019

In May 2019, the FDA granted breakthrough therapy designation to a tumor-infiltrating lymphocyte (TIL) therapy technology known as LN-145 to treat advanced cervical cancer based on data presented by CCR collaborator Iovance Biotherapeutics.  Read more...

In patients with severe chronic lymphocytic leukemia, B cells get stuck in hyperactive mode

Aug 5, 2019

Analyzing how cancer cells respond to stress signals could help clinicians assess the severity of disease in patients with chronic lymphocytic leukemia, according to new research from the Center for Cancer Research, Memorial Sloan Kettering Cancer Center and the National Heart, Lung and Blood Institute.
