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.

New mechanism for regulating differentiation discovered in human embryonic stem cells

Jul 15, 2019

Researchers in the Center for Cancer Research have discovered a new mechanism involving a nuclease complex called the RNA exosome that represses differentiation of human embryonic stem cells. This represents the first time this mechanism has been studied in these cells. Read more...

Gene-regulating microRNAs gain control over hundreds of new genes with common sequence modification

Jul 11, 2019

MicroRNAs have an enormous influence over what happens inside cells. By blocking the activity of specific sets of genes, they help control virtually every known biological pathway and process. Disruptions in microRNAs have been linked to many diseases, and understanding how these molecules function, which genes they control and how they themselves are regulated are high priorities in cancer research.  Read more...

Gastrointestinal tumors harbor T cells that recognize patients’ unique tumor antigens

Jun 25, 2019

CCR scientists, led by Steven A. Rosenberg, M.D., Ph.D., have determined that many common gastrointestinal tumors bear mutations capable of eliciting an immune response, suggesting that immunotherapy could be an effective way to treat these common cancers.  Read more...

Research shows long noncoding RNA influences expression of key HIV receptor

Jun 24, 2019

New research from the Center for Cancer Research has identified a long noncoding RNA that influences the expression of CCR5, a receptor that HIV uses to infect immune cells. The finding points to the molecule as a potential marker that indicates a patient’s susceptibility to the virus. Read more...

Akt protein kinase pathway regulates key step in the initiation of cilia formation

Jun 13, 2019

CCR investigators have discovered that activating the Akt protein kinase pathway stabilizes the binding of the WDR44 protein to the Rab11 protein. This prevents Rab11 from binding to the Rabin8 protein, thereby blocking cilia formation. When Akt is inactive, though, Rab11 instead is bound by FIP3, enhancing its binding to Rabin8, which helps initiate cilia formation. Since abnormalities in cilia formation are associated with a number of types of cancer, these findings point to several potential targets for cancer therapy.   Read more...

Bacterial compound targets cancer-promoting RNA

Jun 10, 2019

Screening more than 3,000 natural products identified a compound that stops the growth of cancer cells by targeting a growth-promoting microRNA. Read more...

Cyclophosphamide works in an unexpected way to curb graft-vs-host disease in mice

May 7, 2019

For years it has been assumed that cyclophosphamide helps reduce the severity of graft-versus-host disease by eliminating alloreactive T cells, but new evidence reveals a different reason.  Read more...

Multiple myeloma

Majority of patients with advanced multiple myeloma respond to CAR T-cell therapy targeting an anti-B-cell maturation antigen in a phase I trial

May 2, 2019

A phase I clinical trial of 33 patients infused with a CAR T-cell therapy using T cells genetically engineered to express an anti-B-cell maturation antigen (BCMA) CAR showed that 85 percent of patients had the burden of their advanced multiple myeloma cut by half or more.  Read more...
