VCU researchers home in on microRNA processing for new cancer therapies

More than a decade of research on the mda-7/IL-24 gene has shown that it helps to suppress a majority of cancer types, and now scientists are focusing on how the gene drives this process by influencing microRNAs.

Newly designed molecule could benefit people with Friedrich's Ataxia

Skin cells taken from patients with a rare genetic disorder are up to ten times more sensitive to damage from ultraviolet A radiation in laboratory tests, than those from a healthy population, according to new research from the University of Bath.

Metabolic plasticity helps metastatic cancer cells survive hostile environments

When metastatic cancer cells need to avoid a threat, they simply reprogram themselves. Rice University scientists are beginning to get a handle on how they survive hostile environments.

Enzyme that breaks down amino acids plays key role in promoting cellular senescence

Permanently arrested cell growth is known as "cellular senescence", and the accumulation of senescent cells may be one cause of aging in our bodies. Japanese researchers have discovered that a certain enzyme in our bodies promotes cellular senescence by producing reactive oxygen species.

Synthetic compound from flaxseed can improve heart function in mice with sepsis

Sepsis is a life-threatening systemic inflammatory condition that develops in response to infection. One of its major complications is cardiovascular dysfunction, in which deterioration of the heart muscle, driven by decreased energy production resulting from reduced oxygen and nutrient supplies, frequently ends in organ failure.

The impact of maternal diabetes on fetal heart development

Congenital heart disease is the most common birth defect. And even with remarkable advances in care, it remains the leading cause of non-infectious death in infants.

Researchers discover how mitochondria deploy a powerful punch against disease-causing bacteria

The constant battle for dominance between disease-causing bacteria and our immune systems has led to the evolution of some crafty warfare tactics on both sides.

Scientists develop micron-sized spheres that catch and destroy contaminants in water

Rice University scientists have developed something akin to the Venus' flytrap of particles for water remediation.

Short high-intensity exercise may be as beneficial as longer moderate exercise

A new study has shown that performing high-intensity interval or sprinting exercise for a few minutes may be equally as beneficial as exercising at a moderate-intensity level for longer periods.

Mitochondrial pathway found to be involved in breast cancer

Researchers have discovered a molecular pathway that controls the movement of mitochondria within breast cancer cells and influences invasiveness.

Targeting pathway controlling mitochondria may reduce cancer invasiveness

Targeting a pathway that controls the movement of mitochondria, the powerhouses of all cells, could reduce cancer invasiveness and resistance to radiotherapy.

BAP1 protein serves as tumor suppressor gene in kidney, eye, bile duct and mesothelioma cancers

Researchers at The University of Texas MD Anderson Cancer Center have shown how BRCA-associated protein 1 (BAP1) serves as a tumor suppressor gene in kidney, eye, bile duct, mesothelioma and other cancers by regulating a form of cell death called ferroptosis, opening up a potential new area of therapy research.

Researchers develop near-infrared fluorophores-based PDT to cure cancer with less side effects

A KAIST research team developed near-infrared fluorophores-based photodynamic therapy that reduced the downside of existing PDTs.

Researchers find ATM protein that can trigger production of antioxidants

One reason we're supposed to eat a variety of colorful fruits and vegetables is because they contain nutritious compounds called antioxidants.

Protein complex that helps shape destiny of developing T cells identified

Like a mentor helping medical students choose between specialties, a protein complex helps shape the destiny of developing T cells, St. Jude Children's Research Hospital scientists have reported.

Novel smart probe may improve post-surgical outcomes for cancer patients

A new Tel Aviv University study explores a novel smart probe for image-guided surgery that may dramatically improve post-surgical outcomes for cancer patients.

Cancer cells co-opt pain-sensing 'neural channel' to increase tolerance against oxidative stress

Anyone who's taken a bite of a sandwich with too much spicy mustard or a piece of sushi with too much wasabi can attest to the tear-inducing sensation these condiments can cause. These loud warnings to the nervous system of exposure to potentially harmful chemicals are triggered by TRPA1, a calcium channel protein sometimes referred to as the "wasabi receptor."

Researchers uncover role of ROS in clearing dead cells

If dead cells accumulate in the body, they can contribute to inflammation and pre-dispose individuals to multiple chronic inflammatory conditions such as rheumatoid arthritis, cardiovascular diseases, Crohn's disease or lupus by uncharacterized pathways.

Finding new drug target for common form of lung cancer

Research by Rutgers Cancer Institute of New Jersey investigators has identified novel functions of the superoxide dismutase 1 (SOD1) enzyme providing support that it could serve as a therapeutic target in the most common type of lung cancer.

EXD2 enzyme facilitates protein production in mitochondria

Researchers from the Genomic Instability and Cancer Laboratory at Institute for Research in Biomedicine (IRB Barcelona) have identified a key role for EXD2 in protein production in the mitochondria, the cellular organelles responsible for the majority of energy generation.
