Reinforced learning

AI masters tightrope walk of cancer treatment dosage

Using a new approach called 'reinforced learning', researchers have taught an artificial intelligence (AI) to responsibly choose the right amount of chemo- and radiotherapy for glioblastoma patients. The technique, which is insprired by behavioural psychology, has given the AI the ability to master the tightrope walk between effective tumor shrinkage and the medications' severe side effects.

AI approach to help myeloma patients

A multidisciplinary team of researchers from the National University of Singapore (NUS) has developed an artificial intelligence (AI) technology platform that could potentially change the way drug combinations are being designed, hence enabling doctors to determine the most effective drug combination for a patient quickly. Applying the platform towards drug resistant multiple myeloma, a type of…

High-fat diet can cause pancreatic cancer – but there's hope

A high-fat diet may promote the growth of pancreatic cancer independent of obesity because of the interaction between dietary fat and cholecystokinin (CCK), a digestive hormone. In addition, blocking CCK may help prevent the spread of pancreatic tumors to other areas of the body (metastases). The new findings are published ahead of print in the American Journal of Physiology—Gastrointestinal…

Switching sides

How cancer cells 'brainwash' their foes

It doesn’t often happen that army generals switch sides in the middle of a war, but when cancer is attacking, it may cause even a gene that acts as the body’s master defender to change allegiance. Researchers at the Weizmann Institute of Science have discovered that this gene’s betrayal can occur in more ways than previously appreciated – and might even return the renegade cells to their…

Growing brain cancer in a dish

Austrian researchers have accomplished an astounding feat: They created organoids that mimic the onset of brain cancer. This method not only sheds light on the complex biology of human brain tumors but could also pave the way for new medical applications.

Acute myeloid leukaemia

Researchers draw AML ‘family trees’ in patients treated with enasidenib

For the first time, a team of international researchers have mapped the family trees of cancer cells in acute myeloid leukaemia (AML) to understand how this blood cancer responds to a new drug, enasidenib. The work also explains what happens when a patient stops responding to the treatment, providing important clues about how to combine enasidenib with other anti-cancer drugs to produce…

Typical mutation in cancer cells stifles immune response

The exchange of a single amino acid building block in a metabolic enzyme can lead to cancer. In addition, it can impair the immune system. It thus blocks the body’s immune response in the battle against the mutant molecule and also impedes immunotherapy against brain cancer. This finding opens new insights into cancer development and progression and it also suggests that rethinking antitumor…

MRI advances approach the realm of precision medicine

MRI has developed rapidly over the past decade in Poland, where clinicians are combining MRI with PET and CT to highlight tumour growth or regression and perfusion. ‘The fact that MRI offers new software and programmes means we can diagnose pathologies more precisely and make a diagnosis faster than a few years ago,’ explained Poland’s national advisor on radiology and diagnostic imaging…

Computer algorithm maps cancer resistance to drugs

New methods of studying the evolution of treatment resistance in head and neck cancer are being developed by researchers at the Johns Hopkins Kimmel Cancer Center. The scientists wanted to examine how cancers acquire resistance to treatment over time and whether those changes could be modeled computationally to determine patient-specific timelines of resistance.

Could senescence be the key to stopping cancer?

Canadian researchers have found a promising way to stop tumour cells from multiplying. In disrupting the composition of ribosomes, the team from Université de Montréal (UdeM) discovered a direct molecular mechanism to stop cancer cells from proliferating, which is called senescence. Their results have been published in Nature Cell Biology. 
“Ribosomes are complex machines composed of both…

Breaking through a tumor's defenses

Babraham Institute researchers have shown that some tumours use not one but two levels of protection against the immune system. Knocking out one level boosted the protective effects of the second and vice versa. The research demonstrates that a two-pronged approach targeting both cell types simultaneously may offer a promising route for the development of new cancer immunotherapies.

Gas embolotherapy

Blowing bubbles for cancer treatment

Recently, scientists have explored another version of embolization, called gas embolotherapy. During this process, the blood supply is cut off using acoustic droplet vaporization (ADV), which uses microscopic gas bubbles induced by exposure to ultrasonic waves. A team of researchers from China and France has discovered that these bubbles could also be used as potential drug delivery systems.

New function assessment

Measuring immune cell response within minutes

T cells fight pathogens and tumors: Researchers from the Universities of Tübingen and Lübeck present a simple and fast method to rapidly assess their function. Due to its simplicity, reliability and versatility, it could be broadly implemented for basic research and in the clinical setting. Methods so far to test T-cell response were technically cumbersome and time-consuming and therefore only…

New method shows 3D images of cancer cells in the body

Making tumour cells glow: Medical physicists at Martin Luther University Halle-Wittenberg (MLU) have developed a new method that can generate detailed three-dimensional images of the body's interior. This can be used to more closely investigate the development of cancer cells in the body. The research group presents its findings in "Communication Physics", a journal published by the…

Tumor-like spheres to help discover smarter cancer drugs

Cancer is a disease often driven by mutations in genes. As researchers learn more about these genes, and the proteins they code for, they are seeking smarter drugs to target them. The ultimate goal is to find ways to stop cancer cells from multiplying out of control, thereby blocking the growth and spread of tumors. Now researchers from The Scripps Research Institute are reporting an innovative…
