Study uncovers one way that p53 acts to prevent cancer cell invasion

The tumor suppressor p53 does all it can to prevent oncogenes from transforming normal cells into tumor cells by killing defective cells or causing them to become inactive.

Researchers examine how diabetes drug can benefit cancer patients

For several years, a class of anti-diabetic drugs known as biguanides, has been associated with anti-cancer properties. A number of retrospective studies have shown that the widely used diabetes drug metformin can benefit some cancer patients.

Researcher discover new chemical class that attacks two key cancer cell building block targets

Imagine cutting down the growth of cancer cells at their earliest stages to halt tumor growth. Research conducted by leading cancer metabolism researchers at Stony Brook University, Paul M. Bingham, PhD, and Zuzana Zachar, PhD, is showing promise in this approach with their clinical investigation of a new class of compounds that disrupt cancer cell mitochondrial metabolism.

Researchers unravel function of proteins involved in cell metabolism

UCPs or uncoupling proteins are present in mitochondria, the powerhouse of each cell in the body. The functions of most of the five known UCPs remain mysterious (UCP2-UCP5), whereby only the distinct function for UCP1 has thus far been discovered.

Metabolic profiling of liver cells suggests new treatments for cirrhosis patients

In a new study that could help doctors extend the lives of patients awaiting liver transplants, a Rice University-led team of researchers examined the metabolic breakdown that takes place in liver cells during late-stage cirrhosis and found clues that suggest new treatments to delay liver failure.

Procellera technology enhances cell migration in in-vitro laboratory testing

Procellera – the world's first wireless microcurrent generating dressing that produces electrical fields through its matrix of microcell batteries – was found to significantly enhance cell migration in in-vitro laboratory testing, according to groundbreaking research led by The Ohio State University Wexner Medical Center Professor Chandan K. Sen. Professor Sen is also the Director of the Comprehensive Wound Center at Ohio State.

New research uncovers abnormal molecular signaling pathways for kidney failure

Prevention and reversal of chronic kidney disease is an urgent public health need. The disease affects 1 in 10 Americans, is debilitating and deadly, and existing drugs, at best, offer only mild delay in progression to end-stage kidney failure.

Long-term physical activity improves cardiovascular health by targeting heart cells' powerhouses

Whether lifting weights in a gym or just walking around the block, exercise has many benefits, such as helping people lose weight and build stronger muscles. Some studies suggest that it may reduce the risk of developing cancer and other diseases.

Study offers new avenue to pursue in quest for desperately needed treatments for ALS

St. Jude Children's Research Hospital scientists led a study showing that mutations in a gene responsible for amyotrophic lateral sclerosis (ALS) disrupt the RNA transport system in nerve cells.

New super-resolution microscopy method could spot dozens of distinct types of biomolecules

A new microscopy method could enable scientists to generate snapshots of dozens of different biomolecules at once in a single human cell, a team from the Wyss Institute of Biologically Inspired Engineering at Harvard University reported Sunday in Nature Methods.

Vitamin C and E supplements blunt endurance training

Vitamin C and E supplements may blunt the improvement of muscular endurance - by disrupting cellular adaptions in exercised muscles - suggests a new study published today [3 February] in The Journal of Physiology.

Parkin and PINK1 function in vesicular trafficking pathway regulates mitochon-drial quality control

Scientists from the Montreal Neurological Institute and Hospital in Canada have discovered that two genes linked to hereditary Parkinson's disease are involved in the early-stage quality control of mitochondria.

Longer reads: Connecting with patients; obesity origins; children with chronic disease

I'd never [before] been encouraged to sit at a patient's bedside -; to stop hurrying for even a moment. Our medical teachers put a premium on accuracy and efficiency, which became conflated with speed.

New dye more effective in detecting, measuring cardiolipin in cell membranes

A team that includes Dartmouth College researchers has discovered a new way to detect cardiolipin, a key indicator of heart diseases and some genetic disorders.

Study shows direct link between metabolism in brain cells and ability to signal information

A new study by scientists at McGill University and the University of Zurich shows a direct link between metabolism in brain cells and their ability to signal information. The research may explain why the seizures of many epilepsy patients can be controlled by a specially formulated diet.

Study compares relative rate of molecular evolution between humans and chimps with their lice

A new study compares the relative rate of molecular evolution between humans and chimps with that of their lice. The researchers wanted to know whether evolution marches on at a steady pace in all creatures or if subtle changes in genes - substitutions of individual letters of the genetic code - occur more rapidly in some groups than in others.

Cardiotoxicity of doxorubicin is mediated through mitochondrial iron accumulation

Doxorubicin is a widely used as a component of chemotherapy regimes; however, the use of doxorubicin is associated with severe cardiotoxicity. It is unclear exactly how doxorubicin promotes cardiotoxicity, but it has been proposed that doxorubicin-associated cardiomyopathy develops as the result of reactive oxygen species (ROS) production and iron accumulation.

MitoQ antioxidant reverses MS-like disease in animal

Researchers at Oregon Health & Science University have discovered that an antioxidant designed more than a dozen years ago to fight damage within human cells significantly helps symptoms in mice that have a multiple sclerosis-like disease.
