Specialized procedure saves a young woman's ability to walk
Through interdepartmental collaboration, a young woman's quality of life and ability to walk were restored following the laparoscopic removal of a rare, benign tumor of neurological origin in the lesser pelvis, known as a schwannoma (also called a neurinoma). In the Central and E
New role of PTGES3 uncovered in liver cancer growth and immune evasion
A research team led by Prof. Wang Hongzhi at the Hefei Institutes of Physical Science, Chinese Academy of Sciences, has found a novel role of prostaglandin E synthase 3 (PTGES3) in liver cancer, revealing how it drives both tumor growth and immune suppression.
Intracellular mechanisms promote tumor survival during hypoxia
Northwestern Medicine scientists have, for the first time, described the underlying mechanisms that regulate how cells rapidly change gene expression in response to hypoxia, a key feature of many treatment-resistant tumors, according to a recent study published in Science Advance
New therapeutic target for cancer identified by revealing how cancer 'hijacks' blueprint f
Anti-angiogenic therapies targeting VEGF have been widely used in cancer treatment, yet their long-term efficacy remains limited. Tumor vascular endothelial cells (TECs) exhibit high adaptive plasticity, enabling them to resist treatment and sustain tumor growth, but the molecula
Family of drugs used for treating muscular dystrophy could improve brain tumor treatment
Family of drugs used for treating muscular dystrophy could improve brain tumor treatment
A drug from the same family licensed for use in patients with Duchenne muscular dystrophy and blood cancer could transform the treatment of meningioma—the most common form of primary brain tumor in adults. Scientists at the Brain Tumor Research Center of Excellence at the Univers
Cancer cell 'degraders' target two proteins at once to defeat treatment resistance
Cancer cell 'degraders' target two proteins at once to defeat treatment resistance
Researchers from two Technion faculties have jointly developed a new compound and demonstrated its effectiveness against aggressive tumor cells.
Kidney cancer gene reveals an unexpected weakness and a new path for treatment
A common genetic mutation that helps some kidney cancers survive may also expose an unexpected weakness, one that MUSC Hollings Cancer Center researchers hope to transform into a new treatment strategy. In a study published in Cancer Research, Aguirre de Cubas, Ph.D., and colleag
AI-guided pathology analysis can help predict immunotherapy response in rare cancers
Researchers from The University of Texas MD Anderson Cancer Center demonstrated that an artificial intelligence (AI)-based analysis of tumor biopsies can predict responses to immunotherapy in a study of patients with rare cancers, published in the Journal for ImmunoTherapy of Can
New mechanism behind breast cancer metastasis uncovered
New mechanism behind breast cancer metastasis uncovered
Researchers at Umeå University show that the protein METTL3 helps breast cancer cells spread. By regulating the release of molecules, METTL3 makes it easier for tumors to invade surrounding tissue and form metastases. The discovery reveals a previously unknown function of METTL3
A portable ultrasound system could make reliable breast imaging more accessible
For people at high risk of developing breast cancer, yearly mammograms may not be enough to detect tumors early. To make earlier diagnosis easier, an MIT team has developed portable detectors based on ultrasound, which could be used much more frequently.
Investigators report promising results from Phase II trial of targeted therapy for rare bi
Results of the ongoing eNRGy trial, a single-arm, multicenter, global Phase II clinical trial evaluating zenocutuzumab in solid tumors positive for Neuregulin 1 (NRG1) gene fusions, reported manageable side effects and clinically meaningful efficacy—including a near doubling of p
Discovery could help prevent cancer drug resistance before it starts
Cancer cells are quick to develop resistance to anti-tumor drugs. New research by scientists from the University of California, Davis, shows how cancers adapt to evade a class of anti-tumor drugs called BET inhibitors and offers hope for more effective therapies.
