Getting old? Slowing down? Blame inefficient mitochondria

In mitochondria, the fuel is oxidised and builds up a pressure of hydrogen ions (protons). These force through molecular turbines and enable the cell to generate ATP, an energy unit that can be used throughout the cell.

Gene silencing and microRNA discovery

One of the body's primary strategies for regulating its genome is a kind of targeted gene silencing orchestrated by small molecules called microRNAs, or miRNAs.

Mitochondria and apoptosis research

The story of how mitochondria are recruited during times of stress to choreograph apoptosis--the cell's dance of death--is a story that fails to tell which particular set of steps the cells use most often, according to investigators at St. Jude Children's Research Hospital and the La Jolla Institute of Allergy and Immunology (San Diego, CA).

New insights that advance the current model of protein motility and muscle contraction

Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it "walks" along other proteins, revealing new structural insights that advance the current model of protein motility and muscle contraction.

African-American women with mitochondrial DNA variant are at increased risk of breast cancer

African-American women who carry the 10398A mitochondrial DNA allele are 60 percent more likely to develop invasive breast cancer than African-American females without that genetic marker, according to research published in the September 1 issue of "Cancer Research."

UCI study helps identify one reason why women have lower stroke risk than men

Estrogen's role as an inhibitor of toxic-free radicals in cerebral blood vessels may be a key reason why premenopausal women have a lower stroke risk than men.

Protein Sirt1 points to new therapies for type 2 diabetes

Opening the possibility of new therapies for type 2 diabetes, researchers at Washington University School of Medicine in St. Louis have found that a protein called Sirt1 enhances the secretion of insulin in mice and allows them to better control blood glucose levels. Their study appears in the August 17 issue of Cell Metabolism.

Decline in energy production by mitochondria appears to be a key problem leading to insulin resistance

A detectable decline in energy production by mitochondria - the organelles that are the cell's furnace for energy production - seems to be a key problem leading to insulin resistance, and thus to type 2 diabetes, according to studies by Howard Hughes Medical Institute researchers.

Researchers shed light on the brain cell damage caused by Alzheimer's disease

The researchers hope that by gaining a better understanding of the disease's cellular impacts, progress can be made towards developing a treatment. The research is reported in the current edition of the Journal of Alzheimer's Disease, published by IOS publishers.

Sildenafil prevents anti-cancer drug induced heart damage

Virginia Commonwealth University researchers have found that the popular impotence drug Viagra prevents damage to the heart from a potent chemotherapeutic agent frequently used in the treatment of breast cancer, leukemia and sarcomas.

Genetic manipulation cuts nerve damage, boosts life span

A novel genetic manipulation significantly extends the life spans of flies by reducing the amount of wear and tear suffered by nerve cells in adults, according to new work published in Cell Metabolism. The findings support the idea that therapies designed to protect the adult nervous system by curbing the production of damaging free radicals might effectively increase longevity in other animals, including humans, the researchers said.

Link between diabetes and obesity

Scientists at Washington University School of Medicine in St. Louis used genetically modified mice to uncover a potentially important link between diabetes and obesity.

Special imaging study shows failing hearts are energy starved

Using magnetic resonance spectroscopy (MRS) for the first time to examine energy production biochemistry in a beating human heart, Johns Hopkins researchers have found substantial energy deficits in failing hearts.

Research breakthrough in treatment of TB and MDR-TB

FASgen Inc.'s compound, FAS20013, has emerged from an intense multi-year program of pre-clinical studies that clearly validate its potential as an ideal new drug for the treatment of tuberculosis and MDR-TB, the disease caused by organisms that are resistant to the drugs now commonly used to treat TB. Initial clinical trials in both TB and MDR-TB are scheduled for later this year.

Study on first new potential drug for tuberculosis in 40 years

454 Life Sciences, a majority-owned subsidiary of CuraGen Corporation, announced today that its proprietary whole genome sequencing technology was used by scientists at Johnson & Johnson Pharmaceutical Research & Development L.L.C. (J&JPRD) to help understand the basis of tuberculosis drug resistance.

Scientists have identified a novel anti-tuberculosis (TB) compound

Scientists at Johnson & Johnson Pharmaceutical Research and Development have identified a novel anti-tuberculosis (TB) compound that works better and faster than the current standard of care in mouse models of TB infection.

A gallery of highly-specific, gene and protein “mug shots” of cancer types would be a powerful for oncologists

Doctors would like to diagnose malignancies rapidly by matching them with highly-specific genetic “mug shots” based on the presence of characteristic mRNAs or proteins. This kind of specificity would facilitate screening and early detection, and would potentially allow targeted treatments specific to each type of cancer

Novel enzyme in sperm is essential for spontaneous and independent movement

A study led by scientists at the University of North Carolina at Chapel Hill has found that a novel enzyme in sperm is essential for spontaneous and independent sperm movement as well as male fertility.

Uncoupling proteins in the human heart

Results of a study in this week’s issue of THE LANCET suggest that respiratory uncoupling and reduced substrate availability might lead to energy deficiency in heart failure.

Zetia co-administered with Fenofibrate significantly reduced LDL ("bad") cholesterol in mixed hyperlipidemia patients

Results from a new study showed that coadministration of Zetia (ezetimibe) and fenofibrate significantly reduced LDL ("bad") cholesterol (LDL-C), non-high density lipoprotein cholesterol (non-HDL-C) and apo B1 in patients with mixed hyperlipidemia and high LDL cholesterol when compared to fenofibrate alone.
