Aspirin is associated with a reduction in the risk of developing several cancers of the digestive tract, including some that are almost invariably fatal, such as pancreatic and liver cancers.
Scientists at Sanford Burnham Prebys have found a new way to kill pancreatic cancer cells by disrupting their pH equilibrium. The study, published in Cancer Discovery, reports how depleting an ion transport protein lowers the pH to a point that compromises pancreatic cancer cell growth. Pancreatic cancer cells—like all cancer cells—have a constant need for energy to support their growth and…
A team of Cardiff University scientists has switched from researching cancer to work that could help towards a vaccine for coronavirus. The team at the School of Medicine usually work on reprogramming viruses so they can target and kill cancer - but are now focusing their efforts to help in the fight against the new virus which is gripping the world. Dr Alan Parker and his team, whose work on…
The causes of 40 percent of all cases of certain medulloblastoma – dangerous brain tumors affecting children – are hereditary. These are the findings of a recent genetic analysis carried out by scientists from the Hopp Children's Cancer Center (KiTZ), the European Molecular Biology Laboratory (EMBL) and numerous colleagues around the world, which have just been published in the scientific…
Researchers have developed the first blood test that can accurately detect more than 50 types of cancer and identify in which tissue the cancer originated, often before there are any clinical signs or symptoms of the disease. In a paper published in the leading cancer journal Annals of Oncology, the researchers show that the test, which could eventually be used in national cancer screening…
A group of researchers led by Leif Schröder from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) have found a way to detect metastases in certain types of cancer in the brain at an early stage, using only minimal amounts of contrast agent. To this end, the team uses a synthetic molecule that helps to detect the formation of new blood vessels, producing much more sophisticated…
Novel advanced imaging biomarkers are being developed in a series of studies at several UK centres that may lead to the earlier assessment of treatment response to glioblastoma (GBM) and a better survival rate. Through a number of clinical trials – and the application of artificial intelligence (AI) to retrospective data sets – the aim is to highlight approaches that will enable clinicians to…
Could the ability of cancer cells to quickly alter their genome be used as a weapon against malignant tumours? Researchers at Uppsala University have succeeded in developing a substance that has demonstrated promising results in experiments on both animal models and human cancer cells. The study is published in the journal Nature Communications.
Cancer cachexia often occurs in cancer patients in an advanced state. This metabolic wasting syndrome leads to severely reduced muscle mass and fat tissue, which cannot be reversed by nutritional support. Furthermore, muscle regeneration is affected during cancer cachexia due to impaired muscle stem cell function. A problem that also occurs often in the aging process. Cancer cachexia is…
The human immune system can recognize and eliminate not only germs but also cancer cells. This is why treatments with weakened germs can help the immune system in its fight against cancer. Researchers at the Max Planck Institute for Infection Biology in Berlin have genetically modified the tuberculosis vaccine BCG in a way that it stimulates the immune system more specifically. Consequently, the…
Magnetic resonance imaging (MRI) usually measures the magnetic moment of the hydrogen atomic nuclei arising from the spin. However, scientists at the German Cancer Research Centre (DKFZ) are investigating the spin of other nuclei for imaging: ‘X-nuclei imaging has a large potential for MRI imaging as the x-nuclei play an important part in many physiological processes,’ according to doctor and…
Liquid biopsy offers a new dimension to detection and stratification of cancer – yet the technique also faces hurdles and challenges in becoming a mainstream diagnostic approach that will help facilitate more personalised treatments. A critical challenge lies in identifying the extremely low concentrations of the bio-analytes of CTC (circulating tumour cells), ctDNA (circulating tumour DNA) and…
More than half of all cancer patients undergo radiation therapy and the dose is critical. Too much and the surrounding tissue gets damaged, too little and the cancer cells survive. Subhadeep Dutta and Karthik Pushpavanam, graduate students working in the lab of Kaushal Rege, Professor at Arizona State University in Tempe, and collaborators at Banner-M.D. Anderson in Gilbert, Arizona, developed a…
A surprising discovery about a rare form of childhood brain cancer suggests a new treatment approach for that cancer – and potentially many others. Researchers at the University of Virginia School of Medicine have determined that the supposedly simple cancer, called medulloblastoma, forms an unexpectedly intricate network to drive its growth. Some tumor cells actually turn into another type of…
A new method to detect cancer in its early stages using a targeted MRI contrast agent that binds to proteins has been identified by a team of researchers led by Georgia State University Regents’ Professor Jenny Yang. In their study, published in the journal Science Advances, Yang and her colleagues at Georgia State and Emory University describe a newly identified biomarker for detection of…
Eric Prossnitz, PhD, from the University of New Mexico Health Services and his team hope to help 93 million obese Americans fight their fat. In a paper published in Science Translational Medicine, they reported that G-1, a cancer-fighting compound they discovered some years ago, reduces fat in obese mice. Although G-1 is currently in phase 1 clinical trials for cancer, Prossnitz and his team are…
Researchers discover a novel checkpoint in immune cells with the potential to treat the cancer cell microenvironment. The recognition of bacterial infections or foreign substances is mediated and controlled by the human immune system. This innate and adaptive immune system comprises the most important metabolic and cellulare processes to fight against infections and other diseases. Paradoxically,…
In their quest to find new and better methods to make cancer cells more susceptible to treatment, Karin Lindkvist and her research group at Lund University in Sweden are looking into the world of molecules, using the X-rays at the MAX IV laboratory. The researchers believe that limiting the cells' access to sugar will make cancer cells more sensitive to treatment. Many of the cancer treatments…
T cells play a huge role in our immune system's fight against modified cells in the body that can develop into cancer. Phagocytes and B cells identify changes in these cells and activate the T cells, which then start a full-blown program of destruction. This functions well in many cases – unless the cancer cells mutate and develop a kind of camouflage that let them escape the immune system…
Researchers at Cardiff University have discovered a new type of killer T-cell that offers hope of a “one-size-fits-all” cancer therapy. T-cell therapies for cancer - where immune cells are removed, modified and returned to the patient’s blood to seek and destroy cancer cells - are the latest paradigm in cancer treatments. The most widely-used therapy, known as CAR-T, is personalised to each…
How can the treatment of soft tissue sarcomas, these particularly resistant and aggressive forms of cancer, be improved and better personalized? An international team led by Wolf Hervé Fridman with researchers from Inserm, Sorbonne Université and Université de Paris at the Cordeliers Research Center, in collaboration with the French League against cancer and Institut Bergonié, has shown that…
A team of researchers from the National University of Singapore (NUS) has discovered a new personalised tool to detect cancer, predict patient survivability and how well a cancer patient would respond to immunotherapy. This tool is a specially-designed cancer 'scorecard' to be used with the standard blood test for cancer (also known as liquid biopsy). This 'scorecard', which the team termed as…
A study led by scientists from Cornell University provides important new insights into a common and deadly type of gastric cancer. Incidence of this cancer, called gastric squamous-columnar junction (SCJ) cancer, also known as gastroesophageal cancer, rose 2.5 times in the United States between the 1970s and 2000s, while cases of all gastric cancers have decreased by more than 80% since the…
Doctors have used focused ultrasound to destroy tumors in the body without invasive surgery for some time. However, the therapeutic ultrasound used in clinics today indiscriminately damages cancer and healthy cells alike. Most forms of ultrasound-based therapies either use high-intensity beams to heat and destroy cells or special contrast agents that are injected prior to ultrasound, which can…
Using a computer algorithm, scientists at Uppsala University have identified a promising new treatment for neuroblastoma. This form of cancer in children, which occurs in specialised nerve cells in the sympathetic nervous system, may be life-threatening. In the long term the discovery, described in the latest issue of the scientific journal Nature Communications, may result in a new form of…
