In a new study, researchers at the University of Michigan Rogel Cancer Center uncovered a gene that is overexpressed in mutated IDH1. Studies in human cells and a novel mouse model both show that this gene, called ZMYND8, plays a critical role in the radiation resistance. When they knocked down the gene, the glioma cells became responsive to radiation treatment.

New UCLA-led research suggests that antiretroviral drugs called TAF and TDF directly reduce energy production by mitochondria, structures inside cells that generate the power that cells use to function. Both drugs led to reduced cellular oxygen consumption rates, a measure of the ability of the mitochondria to produce energy, compared with controls.

Columbia Engineering neuroscientists identified a specific neural mechanism in the human brain that tags information with emotional associations for enhanced memory. The team demonstrated that high-frequency brain waves in the amygdala, a hub for emotional processes, and the hippocampus, a hub for memory processes, are critical to enhancing memory for emotional stimuli. Disruptions to this neural mechanism, brought on either by electrical brain stimulation or depression, impair memory specifically for emotional stimuli.
A tendency for one or both spouses to avoid or withdraw from tough conversations could set up married couples for emotional distress, bad feelings about their relationship, chronic inflammation and lowered immune function, new research suggests.
COVID-19 is changing household behaviors related to how we are exposed to various household chemicals linked to poor health outcomes.
A new study led by scientists at La Jolla Institute for Immunology (LJI) shows how ideal antibodies against SARS-CoV-2 hit their marks. Now scientists are looking at how we might harness their power in new antibody therapeutics and even more effective COVID-19 vaccines.
Columbia Nursing ranks first among U.S. nursing schools in NIH research funding for FY 2022.
It’s ‘lights out’ for antibiotic-resistant superbugs as next-generation light-activated nanotech proves it can eradicate some of the most notorious and potentially deadly bacteria in the world.
A specific colonization of microbes in the reproductive tract is commonly found in women with ovarian cancer, according to a new study from Mayo Clinic's Center for Individualized Medicine. The discovery, published in Scientific Reports, strengthens evidence that the bacterial component of the microbiome — a community of microorganisms that also consists of viruses, yeasts and fungi — is an important indicator for early detection, diagnosis and prognosis of ovarian cancer.
UC San Diego scientists discover a molecular pathway critical to the initiation of pancreatic tumors. The findings may inspire new chemotherapeutic drugs targeting early stages of tumor formation and spread.
In the past decade, researchers have begun to appreciate the importance of a two-way communication that occurs between microbes in the gastrointestinal tract and the brain, known as the gut–brain axis.
Humans and chimpanzees differ in only one percent of their DNA. Human accelerated regions (HARs) are parts of the genome with an unexpected amount of these differences.
A new study led by Cedars-Sinai and the University of California, San Francisco (UCSF), has determined that altering a cellular process can lead stem cells—cells from which other cells in the body develop—to die or regenerate.
