Novel therapeutic strategy shows promise against pancreatic cancer

Pancreatic cancer is notoriously difficult to cure or even treat. Now, a new strategy has succeeded in making pancreatic tumors visible to the immune systems of mice and vulnerable to immune attack, reducing cancer metastases by 87%.

Could diet modification make chemotherapy drugs more effective for patients with pancreatic cancer?

The findings of a new study suggest that a ketogenic diet — which is low in carbohydrates and protein, but high in fat — helps to kill pancreatic cancer cells when combined with a triple-drug therapy. In laboratory experiments, the ketogenic diet decreased glucose (sugar) levels in the tumor, suggesting the diet helped starve the cancer. In addition, this diet elevated ketone bodies produced by the liver, which put additional stress on the cancer cells.

Bone marrow cancer: Potential drug targets

New research finds that patients with ASXL1-mutant chronic myelomonocytic leukemia — an uncommon type of cancer of the bone marrow — have distinctive epigenetic changes that can activate harmful genes and cause the cancer to grow faster. The ASXL1 genetic mutation also can transform the disease into the more aggressive acute myeloid leukemia.

Researchers put a spotlight on aggressive cancer cells

Metastases in cancer are often caused by a few abnormal cells. These behave more aggressively than the other cancer cells in a tumor. Researchers are now on a method to detect these cells.

Treating cancer with light-sensitive nanoscale biomaterials

Treating cancer and other diseases with laser light is not currently considered routine, but new approaches using nanoparticles show some promise in improving existing techniques. Researchers review the status of the field and by combining photothermal therapy or photodynamic therapy with nanomaterials, they have been able to apply these types of phototherapies while also delivering drugs to sites in the body that are otherwise inaccessible. It is also possible to combine PTT and PDT into a single treatment, creating an even more powerful treatment method.

Spider silk can stabilize cancer-suppressing protein

The p53 protein protects our cells from cancer and is an interesting target for cancer treatments. The problem is, however, that it breaks down rapidly in the cell. Researchers have now found an unusual way of stabilizing the protein and making it more potent. By adding a spider silk protein to p53, they show that it is possible to create a protein that is more stable and capable of killing cancer cells.

Laser flashes for cancer research

Irradiation with fast protons is a more effective and less invasive cancer treatment than X-rays. However, modern proton therapy requires large particle accelerators, which has experts investigating alternative accelerator concepts, such as laser systems to accelerate protons. Such systems are deployed in preclinical studies to pave the way for optimal radiation therapy. A research team has now successfully tested irradiation with laser protons on animals.

New hope for treatment of infant cancer that has puzzled researchers for decades

New research has begun to unravel the mystery of why a particular form of leukaemia in infants has defied efforts to improve outcomes, despite significant improvements in treating older children. Scientists have now found subtle differences in the cell type that causes B acute lymphoblastic leukaemia (B-ALL) that may help to explain why some cases are more severe than others.
