Kent Hunter’s circadian gene research highlighted across national news

Sep 23, 2016

Kent Hunter’s research on breast cancer metastasis and the circadian gene has been covered by Reuters, Fox News and New Scientist. His research suggests that changes to the gene involved in regulating circadian rhythms could influence the metastasis of breast cancer. Hunter is the Deputy Chief of CCR’s Laboratory of Cancer Biology and Genetics.

High levels of potassium inside tumors suppress immune activity

Sep 15, 2016

Nicholas P. Restifo, a senior investigator in CCR’s Surgery Branch and his team have discovered that an abundance of potassium inside tumors dampens immune responses, helping the tumors evade the body’s defenses. In animal experiments, genetically equipping immune cells rid themselves of potassium made them more effective at fighting cancer. The finding, published September 14, 2016, in the journal Nature, suggests a tactic for improving the effectiveness of cancer immunotherapies.  Learn more...

Targeting DNA repair proteins shown to prevent and shrink tumors

Sep 13, 2016

Andre Nussenzweig, NIH distinguished investigator and chief of the Laboratory of Genome Integrity, collaborated with a team to find new therapies for patients with Acute Myeloid Leukemia (AML). The team discovered that targeting the DNA repair proteins ATM/ATR kinases worked to prevent tumor formation and reduce tumors in established cancers in mouse models. Read more…

Study finds gene expression classifier for early stage squamous cell carcinoma

Sep 7, 2016

Senior Investigator and Chief of the Laboratory of Human Carcinogenesis Curt Harris has published a new study on squamous cell carcinoma and developing biomarkers that can identify high-risk early stage lung cancer patients. The group presents a prognostic classifier based on gene expression that can be used as a tool to guide clinical decisions. Learn more...

Study finds remarkable synergy between immunotoxins and actinomycin D

Sep 7, 2016

Ira Pastan, a senior investigator and co-chief of the Laboratory of Molecular Biology, together with a team of researchers, published a new study in PNAS evaluating Actinomycin D and the immunotoxin RG7787. Actinomycin D is a strong inhibitor used for treating many cancers, and the researchers found that when combined with RG7787, they acted together to kill a variety of cancer cell lines and shrink tumors in mice. These data strongly support the use of Actinomycin D to enhance immunotoxin action in humans. Read more…

Tumor DNA in blood may signal response to T-cell transfer immunotherapy

Sep 2, 2016

A pilot study by Steven Rosenberg (Surgery Branch) and Mark Raffeld (Laboratory of Pathology) suggests that tumor DNA circulating in the blood of patients with cancer might be a biological marker for determining, soon after the treatment has started, whether a form of immunotherapy is likely to work for a given patient.

Distinguished investigator Shiv Grewal discusses heterochromatin assembly

Sep 2, 2016

Shiv Grewal, an NCI Distinguished Investigator and Chief of the Laboratory of Biochemistry and Molecular Biology, has spent most of his career researching heterochromatin and how it effects cell differentiation and adaptation. He has discovered that RNA plays a large role in targeting heterochromatin assembly and can be used as a targeting mechanism. He discusses those findings and what they mean for cancer research with Proceedings of the National Academy of Sciences of the United States of America.  Learn more...

CCR researcher finds oxygen can impair cancer immunotherapy in mice

Aug 25, 2016

Dr. Nicholas Restifo and his colleagues have identified a mechanism in mice by which anticancer immune responses are inhibited within the lungs, a common site of metastasis for many cancers. This mechanism involves oxygen inhibition of the anticancer activity of T cells. Inhibiting the oxygen-sensing capability of immune cells, either genetically or pharmacologically, prevented lung metastasis. Read more…

Seeking to unlock the genomic keys to ovarian cancer
