Scientists identify dangerous 'two-faced' protein crucial to breast cancer spread and growth

Two critical properties of cancer cells are their ability to divide without restraint and to spread away from the primary tumor to establish new tumor sites.

Scientists discover how certain antibiotics kill bacteria

A series of genetic clues led a team of Boston University biomedical engineers to uncover exactly how certain antibiotics kill bacteria.

Discovery explains how insulin prompts fat and muscle cells to absorb glucose

A PhD student at Sydney's Garvan Institute of Medical Research has uncovered an important piece in the puzzle of how insulin works, a problem that has plagued researchers for more than 50 years.

By imaging live cells, researchers show how hepatitis C replicates

The hepatitis C virus is a prolific replicator, able to produce up to a trillion particles per day in an infected person by hijacking liver cells in which to build up its viral replication machinery.

Study specifies chemical pathway for ions through the cell membrane

Life ultimately depends on the traffic of tiny charged particles through porous proteins studding the membrane surrounding every cell. In research published in Nature, scientists at The Rockefeller University have for the first time mapped a stepping-stone pathway of amino acids that these charged particles, or ions, follow across cell membranes.

Scientists image transfer of antibodies from mother's milk, to baby's gut

The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. Those antibodies, donated by transfer across the placenta before birth or via breast milk after birth, help shape a baby's response to foreign pathogens and may influence the later occurrence of autoimmune diseases.

New rapid test for rare leukemia

A new twist on a well-known cell sorting technique may allow physicians to diagnose rare leukemias in hours instead of weeks, according to a study by researchers at the Stanford University School of Medicine and UC-San Francisco.

Effectiveness of Mediterranean diet confirmed for chronic disease prevention

It is effective in chronic diseases such as cardiovascular diseases, cancer, diabetes, hypertension or osteoporosis. Experts have insisted that it is possible to prevent 80% cardiovascular diseases and 40% different types of cancer through diet, physical exercise and other healthy habits. Scientists of the UGR are specifically analysing how cells react against aggressions which cause pancreatic alterations and result in cancer.

New discovery on growth factor - breakthrough for cancer research

A research team at the Ludwig Institute and Uppsala University has discovered an entirely new signal path for a growth factor that is of crucial importance for the survival and growth of cancer cells.

New cutting edge laser technology provides view into body's chemical messenger system

Researchers at The University of Nottingham have developed a unique technology that will allow scientists to look at microscopic activity within the body's chemical messenger system for the very first time, live as it happens.

Century old rule of chemistry overturned - major implications for drug delivery

A new study by research chemists at the University of Warwick has challenged a century old rule of pharmacology that defined how quickly key chemicals can pass across cell walls. The new observations of the Warwick researchers suggest that the real transport rates could be up to a hundred times slower than predicted by the century old "Overton's Rule". This could have major implications for the development and testing of many future drugs.

ICMT enzyme shows potential as target in treating blood cancer

A discovery by a research team with the Sahlgrenska Academy at Gothenburg University in Sweden may lead to new treatments for blood cancer and other diseases. By stopping the production of a specific enzyme, ICMT, researchers were able to alleviate disease symptoms in mice with blood cancer.

Stanford develop method to overcome multiple drug resistant diseases

Many drugs once considered Charles Atlases of the pharmaceutical realm have been reduced to the therapeutic equivalent of 97-pound weaklings as the diseases they once dispatched with ease have developed resistance to them.

Some bacteria steal iron from their human hosts - discovery could lead to new ways to fight tuberculosis

Like their human hosts, bacteria need iron to survive and they must obtain that iron from the environment. While humans obtain iron primarily through the food they eat, bacteria have evolved complex and diverse mechanisms to allow them access to iron.

microRNA may influence development of alcohol tolerance

In recent years, a class of small molecules known as microRNAs have been found to play an important role in regulating gene products in most animal and plant species.

How anti-depressants and cocaine interact with brain

In a first, scientists from Weill Cornell Medical College and Columbia University Medical Center have described the specifics of how brain cells process antidepressant drugs, cocaine and amphetamines. These novel findings could prove useful in the development of more targeted medication therapies for a host of psychiatric diseases, most notably in the area of addiction.

Tethered bilayer membrane may unlock secrets of early-stage Alzheimer's

Researchers at the National Institute of Standards and Technology (NIST) and three collaborating institutions are using a new laboratory model of the membrane surrounding neurons in the brain to study how a protein long suspected of a role in early-stage Alzheimer's disease actually impairs a neuron's structure and function.
