Miglustat shows promise for cystic fibrosis

Miglustat is a drug currently under phase 2 clinical trials on patients suffering from cystic fibrosis (1). Its potential for treating the disease was discovered in 2006 thanks to the work of Frédéric Becq's team at the Institute of Cell Physiology and Biology (CNRS/Université de Poitiers), funded by the associations Vaincre la Mucoviscidose, MucoVie66, La Pierre Le Bigaut and ABCF2.

Research reveals major genetic differences between blood and tissue cells

Research by a group of Montreal scientists calls into question one of the most basic assumptions of human genetics: that when it comes to DNA, every cell in the body is essentially identical to every other cell. Their results appear in the July issue of the journal Human Mutation.

Skin cancer researchers throw new light on tumour growth

Three researchers from the Dermatology Research Foundation at the University of Sydney have identified a compound produced by certain fatal skin cancer tumours, providing new hope for developing treatments.

New insight into apoptosis

A study by Nanyang Technological University (NTU)'s Assistant Professor Li Hoi Yeung, Assistant Professor Koh Cheng Gee and their team have made an important contribution to the understanding of the process that cells go through when they die. This process known as 'apoptosis' or programmed cell death, is a normal process in the human body which removes perhaps a million cells a second.

Cells use import machinery to export their goods as well

In the bustling economy of the cell, little bubbles called vesicles serve as container ships, ferrying cargo to and from the port - the cell membrane. Some of these vesicles, called post-Golgi vesicles, export cargo made by the cell's protein factory.

Handle with care: Telomeres resemble DNA fragile sites

Telomeres, the repetitive sequences of DNA at the ends of linear chromosomes, have an important function: They protect vulnerable chromosome ends from molecular attack.

MicroRNAs hold promise for treating diseases in blood vessels

A newly discovered mechanism controls whether muscle cells in blood vessels hasten the development of both atherosclerosis and Alzheimer's disease, according to an article published online today in the journal Nature.

Harnessing nanoparticles to track cancer cell changes

The more dots there are, the more accurate a picture you get when you connect them. Cancer researchers adopting that philosophy have developed a new imaging technology that could give scientists the ability to simultaneously measure as many as 100 or more distinct features in or on a single cell. In a disease such as cancer, that capability would provide a much better picture of what is going on in individual tumor cells.

Protein regulates movement of mitochondria in brain cells

Scientists have identified a protein in the brain that plays a key role in the function of mitochondria - the part of the cell that supplies energy, supports cellular activity, and potentially wards off threats from disease.The discovery, which was reported today in the Journal of Cell Biology, may shed new light on how the brain recovers from stroke.

New discovery on Huntington's disease

Researchers at the University of Illinois at Chicago College of Medicine have discovered how the mutated huntingtin gene acts on the nervous system to create the devastation of Huntington's disease. The report of their findings is available in Nature Neuroscience online.

Discovery of key gene in deadly inflammatory breast cancer

Aggressive, deadly and often misdiagnosed, inflammatory breast cancer (IBC) is the most lethal form of primary breast cancer, often striking women in their prime and causing death within 18 to 24 months.

Researchers discover how prion protein damages brain cells

Scientists at the National Institutes of Health have gained a major insight into how the rogue protein responsible for mad cow disease and related neurological illnesses destroys healthy brain tissue.

Stopping type 1 diabetes damage with vitamin C

Researchers at the Harold Hamm Oklahoma Diabetes Center have found a way to stop the damage caused by Type 1 diabetes with the combination of insulin and a common vitamin found in most medicine cabinets.

Gene activity reveals dynamic stroma microenvironment in prostate cancer

As stroma - the supportive framework of the prostate gland - react to prostate cancer, changes in the expression of genes occur that induce the formation of new structures such as blood vessels, nerves and parts of nerves, said researchers at Baylor College of Medicine in a report that appears in the current issue of the journal Clinical Cancer Research.

Research identifies 3D structure of key nuclear pore building block

The genome of complex organisms is stashed away inside each cell's nucleus, a little like a sovereign shielded from the threatening world outside.

Stopping fatty change in heart cells

Heart failure is one of the world's most frequent causes of death - caused by conditions such as diabetes and obesity. With people who are overweight, the heart has to do more work in order to pump the blood through the circulatory system and this causes an increase in blood pressure.

Scientists create pig stem cells

Scientists have managed to induce cells from pigs to transform into pluripotent stem cells - cells that, like embryonic stem cells, are capable of developing into any type of cell in the body. It is the first time in the world that this has been achieved using somatic cells (cells that are not sperm or egg cells) from any animal with hooves (known as ungulates).

Activated stem cells in damaged lungs could be first step toward cancer

Stem cells that respond after a severe injury in the lungs of mice may be a source of rapidly dividing cells that lead to lung cancer, according to a team of American and British researchers.
