Scientists at Huntsman Cancer Institute at the University of Utah report today the development of new models to study molecular characteristics of tumors of the lung and pancreas that are driven by mutations in a gene named NTRK1. The findings were published today in the journal Cell Reports.
In an analysis of how regulators review pesticides for their potential to cause cancer, researchers at Silent Spring Institute identified more than two dozen registered pesticides that were linked with mammary gland tumors in animal studies. The new findings raise concerns about how the US Environmental Protection Agency (EPA) approves pesticides for use and the role of certain pesticides in the development of breast cancer.
Number of macrophages in tumor tissue enables prognosis of lung tumor progression.
20 percent of the middle-aged UK South Asian population may have a very severe vitamin D deficiency, a new study in the British Journal of Nutrition reports. Such deficiency can lead to health problems such as osteomalacia (softening of the bones) and other chronic diseases.
The mechanism unveiled triggers a mutation fog, causing hundreds of mutations in each tumor, which spread through the genome of lung, head-and-neck and breast cancers. Researchers from the Genome Data Science Lab have identified the antiviral APOBEC3A enzyme as the major cause of this new type of hypermutation. Published in Nature Genetics, the study shows how the mutation fog process generates many oncogenic "cancer driver" mutations, thus accelerating tumour development.
Researchers from Josep Carreras Leukemia Research Institute participate in an international study that confirms for the first time that mutation of the two TP53 gene's copies is associated with a worse prognosis in myelodysplastic syndromes, a group of blood cancers a more frequent in elderly population. The results of this study have been published in Nature Medicine journal and represent an advance in the diagnosis and treatment of this type of hematological cancer.
* Patients with glioma - a very common type of tumour originating in the brain - see improvement in survival rates with combined treatment of radiotherapy plus temozolomide * Researchers found a novel mechanism on how tumours evade chemotherapy through genomic rearrangements of the MGMT DNA repair gene * This finding is potentially relevant for updating the methods used to monitor temozolomide efficacy. Genomic rearrangement could be a marker to be detected in blood samples and help make therapeutic decisions
Changes in the number of patients with newly identified cancer before and during the COVID-19 pandemic in the United States are examined in this observational study.
A potentially safer, more effective chemotherapy treatment for patients with blood-related cancers, such as leukemia, who need a particular bone marrow transplant procedure is under study at the University of Arizona Health Sciences. The procedure is known as a haploidentical (half-matched) bone marrow transplantation, or "haplo-BMT," providng an alternate source of stem cells for patients needing a bone marrow transplant but unable to find a perfect or near-perfect donor match for human leukocyte antigens.
A test which detects changing levels of tumour fragments in the blood may be an easy, non-invasive and quick way to predict who will benefit from immunotherapy, a treatment option for advanced cancers.
