University of Texas at Dallas scientists have demonstrated that the growth rate of the majority of lung cancer cells relates directly to the availability of a crucial oxygen-metabolizing molecule. In a preclinical study, recently published in Cancer Research, biologist Dr. Li Zhang and her team showed that the expansion of lung tumors in mice slowed when…

Treating breast tumors with two cancer drugs simultaneously may prevent endocrine resistance by attacking the disease along two separate gene pathways, scientists at the University of Illinois found in a new study. The two drugs used in the study, selinexor and 4-OHT, caused the cancer cells to die and tumors to regress for prolonged periods,…

11,000 people are predicted to die from acute myeloid leukemia (AML) in 2019, according to the American Cancer Society. The cancer starts in the bone marrow. There, mutated genes fail to prevent blood cells from replicating again and again and again, growing tumors. Chemotherapy helps two out of three patients achieve remission. And recently, drug…

A consortium of researchers led by Georgetown Lombardi Comprehensive Cancer Center investigators have completed the largest analysis of a new gene fusion they believe is responsible for development of a wide spectrum of cancer types. They say their studies show that errant gene fusions in neuregulin-1 or NRG1, which are present in about 0.2 percent…

Every year more than 1.7 million women all over the world are diagnosed with breast cancer, with the disease ending fatally for around half a million patients. In the fight against breast cancer, research is being done into novel therapeutic approaches that are designed to target cancer cells more precisely and also activate the tumor-associated…

There could be new treatments on the horizon for diffuse intrinsic pontine glioma, or DIPG, a devastating form of brain cancer that afflicts young children and is currently incurable. Recent experiments in animal models of the disease have identified an experimental drug that effectively destroys DIPG cells. And a team of Rockefeller scientists just figured…

Experimenting with mice, Johns Hopkins researchers report they have successfully used positron emission tomography (PET) scans to calculate in real time how much of an immunotherapy drug reaches a tumor and what parts of a cancer remain unaffected. The technique uses PET imaging of a synthesized radiolabeled protein that locks on to tumor cells, letting…

Researchers have identified two new nuclear medicine tracers that make it easier to diagnose and potentially treat cancer. A proof-of-concept investigation, published in the March issue of The Journal of Nuclear Medicine, reports that 68Ga-FAPI positron emission tomography/computed tomography (PET/CT) provides high-contrast images with quality equal to or better than that of the standard 18F-FDG…

Princeton University researchers are gaining new insights into the causes and characteristics of diseases by harnessing machine learning to analyze molecular patterns across hundreds of diseases simultaneously. Demonstrating a new tool now available to researchers worldwide, the team of computer scientists and biologists has already uncovered and experimentally confirmed previously unknown contributions of four genes…
