Combination immunotherapy targets cancer resistance

Cancer immunotherapy drugs have had notable but limited success because in many cases, tumors develop resistance to treatment. But researchers at Yale and Stanford have identified an experimental antibody that overcomes this problem by targeting a wider range of immune cells linked to tumor growth. Existing cancer immunotherapies act on only a […]

Improved method of engineering T-cells to attack cancer

Using CRISPR genome editing, the team took the genetic engineering of killer T-cells one step further by removing their non-cancer specific receptors and replacing them with ones that would recognise specific cancer cells and destroy them. Dr Mateusz Legut from Cardiff University, who led the study while undertaking a Cancer […]

How Disposable Diapers Can Improve Measurements of Tumor Growth

Catching cancer early can make all the difference for successful treatment. A common screening practice measures tumor growth with X-ray computed tomography (CT), which takes a series of cross-section images of the body. Before they are used in clinics, researchers test multiple CT imaging techniques with standard objects called “phantoms,” […]

Cell-weighing method could help doctors choose cancer drugs

Doctors have many drugs available to treat multiple myeloma, a type of blood cancer. However, there is no way to predict, by genetic markers or other means, how a patient will respond to a particular drug. This can lead to months of treatment with a drug that isn’t working. Researchers […]

Dynamic Differences

Since it first evolved in the common ancestor to multicellular animals some one billion years ago, the p53 family of genes has played the role of genomic guardian for countless organisms. So essential is its task—to protect the DNA of cells from damage and stress—that some form of p53 can […]

Cell Mapping Initiatives Aim to Uncover Hidden Pathways of Disease

Nevan Krogan, PhD, is a mapmaker, but the object of his exploration is not any newfound continent or alien world. Instead, he and his colleagues map cells. Rather than cities, towns and interstates, these maps show proteins, genes, and the shifting, convoluted network of interactions between them. Learning to read […]

‘Mini liver tumours’ created in a dish for the first time

Scientists have created mini biological models of human primary liver cancers, known as organoids, in the lab for the first time. In a paper published in Nature Medicine, the tiny laboratory models of tumours were used to identify a new drug that could potentially treat certain types of liver cancer. Primary liver cancer […]

Study reveals why testicular cancer responds to chemo

Cornell researchers have taken a major step toward answering a key question in cancer research: Why is testicular cancer so responsive to chemotherapy, even after it metastasizes? Professional cyclist Lance Armstrong, for example, had testicular cancer that spread to his lung and brain, yet he made a full recovery after […]

A Step Toward Diabetes Immunotherapy

Harvard Medical School researchers at Boston Children’s Hospital have reversed type 1 diabetes in mice by infusing blood stem cells pretreated to produce more of a protein called PD-L1, which is deficient in mice and people with type 1 diabetes. The stem cells curbed the autoimmune reaction in cells from […]

Targeting cancer without destroying healthy T-cells

The team of researchers, working with biopharmaceutical company Autolus Ltd, have discovered a method of targeting the cancer without destroying healthy T-cells, essential to the immune system. Lymphomas arise when immune cells, called lymphocytes, that protect us against germs, become cancerous. There are two types of lymphocytes: B-cells and T-cells. […]

Study reveals how drug could derail synapse loss in Alzheimer's disease

A recent multi-centre study, led by King’s College London and the University of Manchester, has established that synapse loss in Alzheimer’s disease is driven by a specific signalling pathway. This pathway is called the Wnt-planar cell polarity (PCP) signalling pathway and it may be pivotal to the progressive neurodegeneration seen […]

Discovery suggests better way to treat certain prostate cancers, lymphomas

Certain prostate cancers and lymphomas have a major genetic weakness that doctors can exploit to help save patients’ lives, researchers at the University of Virginia School of Medicine have discovered. The weakness makes the subset of cancers particularly vulnerable to chemotherapy and radiation therapy, suggesting that those approaches should be […]

How cells detect, mend DNA damage may improve chemotherapy

The busy world inside a cell is directed by its DNA blueprint. When the blueprints are altered, cells can sicken, die or become cancerous. To keep DNA in working order, cells have ways to detect and mend damaged DNA. Now, researchers at Washington University School of Medicine in St. Louis […]
