New drug combination promising for treating aggressive breast cancer in brain

Carey K. Anders, MD (Damon Runyon Clinical Investigator '12-'15), and C. Ryan Miller, MD, PhD (Damon Runyon Clinical Investigator '09-'12) of UNC Lineberger Comprehensive Cancer Center, Chapel Hill, and colleagues, reported that they identified a drug treatment strategy that can improve survival for a particularly aggressive breast cancer sub-type (triple negative breast cancer) after it has spread to the brain. They demonstrated, in a mouse model of this cancer, that a combination of the drugs carboplatin and a PARP inhibitor improved survival.

Blocking cellular mechanism may make chemotherapy more effective

Maximilian W. Popp, PhD (HHMI-Damon Runyon Fellow '12-'15) and colleagues at the University of Rochester, Rochester, discovered that stopping a cellular quality-control mechanism can make chemotherapy more effective. This mechanism is called NMD (nonsense-mediated mRNA decay). The researchers found that exposing breast cancer cells to a molecule that inhibits NMD prior to treatment with doxorubicin, a drug used to treat leukemia, breast, bone, lung and other cancers, speeds cancer cell death.

Genetics underlying rare blood cancer identified

Eirini Papapetrou, MD, PhD (Damon Runyon-Edward P. Evans Foundation Innovator '13-'16) of Icahn School of Medicine at Mount Sinai, New York, reported the results of a technique called cellular reprogramming that takes mature blood cells from patients with myelodysplastic syndrome (MDS) and reprograms them back into stem cells to study the genetic origins of MDS. MDS is a rare blood cancer that can progress into acute leukemia; its causes are not well understood.

Metformin and Vitamin D3 show promise in colorectal cancer prevention

Li Li, MD, PhD (Damon Runyon Clinical Investigator '01-'06), of Case Western Reserve University, Cleveland, and colleagues, demonstrated that a combination of the diabetes drug metformin and vitamin D3 work together to prevent colorectal cancer in two animal models. They plan to advance these findings to develop clinical trials in humans. These results were reported in the journal Cancer Prevention Research.

American Association for Cancer Research names recipient of prestigious award

William C. Hahn, MD, PhD (Damon Runyon Fellow '98-'99) of the Dana-Farber Cancer Institute, Boston, will be honored with the 39th annual AACR-Richard and Hinda Rosenthal Memorial Award. He is being recognized for his seminal contributions to the understanding of the mechanisms underlying cancer initiation, maintenance, and progression. His work has defined new paradigms and has provided a foundation for novel therapeutic approaches that are being tested in the clinic. He will receive the award at the AACR Annual Meeting 2015 in April.

Genome-wide screen gives insight on cancer metastasis and tumor evolution

Sidi Chen, PhD (Damon Runyon-Dale F. Frey Scientist ‘15, Damon Runyon Fellow '12-'15) and Feng Zhang, PhD (Damon Runyon-Rachleff Innovator '12-'14), of the Broad Institute and MIT’s David H. Koch Institute for Integrative Cancer Research, Cambridge, used CRISPR-Cas9 gene-editing technology to systematically target every gene in the genome in an animal model. The study revealed genes involved in tumor evolution and metastasis, including some well-known tumor suppressor genes as well as novel genes not previously linked to cancer.

New pathway for slowing BRCA tumor growth

Agnel Sfeir, PhD (Damon Runyon-Rachleff Innovator ‘13-‘15) and colleagues at New York University School of Medicine, New York, reported that inhibiting the action of a particular enzyme called polymerase theta, or PolQ, dramatically slows the growth of tumor cells containing BRCA1 and BRCA2 genetic mutations. This could have an impact on breast and ovarian cancers. The findings were published in the journal Nature.

Identification of two genes that trigger ovarian cancer

Terry Magnuson, PhD (Fellowship Award Committee Member), William Y. Kim, MD (Damon Runyon Clinical Investigator ‘09-‘14), and colleagues at the University of North Carolina, Chapel Hill, created the first mouse model of ovarian clear cell carcinoma using data from The Cancer Genome Atlas. Specific types of mutation of the genes ARID1A and PIK2CA gave rise to ovarian cancer 100 percent of the time.

Nanoparticles for detecting cancer cells

Moritz F. Kircher, MD, PhD (Damon Runyon-Rachleff Innovator ‘14-‘16) and colleagues at Memorial Sloan Kettering Cancer Center, New York, reported development of a new type of nanoparticle called “nanostars,” which accumulate in tumor cells and scatter light, making the tumors easily visible with a special camera. The nanoparticles cannot enter noncancerous cells in the body, so only the cancer cells light up.

New connection established between cell metabolism and stem cell identity

Lydia Finley, PhD (Damon Runyon Jack Sorrell Fellow ‘13-‘17) of Memorial Sloan Kettering Cancer Center, New York, and colleagues, demonstrated that stem cells can rewire their metabolism to enhance a mechanism that helps them avoid committing to a specific fate; in turn, this improves stem cells’ ability to renew themselves. She showed that the nutrients a stem cell uses, and how it uses them, can contribute to a cell’s fate by influencing gene expression through epigenetic modifications.
