Potential new ways to prevent smoking-related cellular damage

In the current issue of PLoS One, researchers show how a poorly understood and previously unsuspected mechanism may be the key to understanding how life-style associated forms of oxidative stress, such as exposure to cigarette smoke, damage cells in the lungs.

How cells change the pace of their steps

Scientists at UC San Diego have discovered how cells of higher organisms change the speed at which they move, a basic biological discovery that may help researchers devise ways to prevent cancer cells from spreading throughout the body.

Discovery of pathway that controls cell size and division

Organisms precisely regulate cell size to ensure that daughter cells have sufficient cellular material to thrive or to create specific cell types: a tiny sperm versus a gargantuan egg for example.

Discovery of key HIV protein which makes cell membranes bend more easily

Carnegie Mellon University scientists have made an important discovery that aids the understanding of why HIV enters immune cells with ease.

Nicotine rush hinges on sugar in neurons

As with other questions involving good sensations, the answer appears to be sugar.

Protein km23 - potential target for ovarian cancer treatment

A traffic cop protein in the cell may have an even more important role: transporting a messenger protein that tells components in the nucleus to stop cell growth.

Protein dysferlin critical for resealing heart muscle cell membranes

During vigorous exercise, heart muscle cells take a beating. In fact, some of those cells rupture, and if not for a repair process capable of resealing cell membranes, those cells would die and cause heart damage (cardiomyopathy).

Genetic mutation that may alter response to cancer therapeutics found

Researchers from Eli Lilly & Company and the Phoenix-based Translational Genomics Research Institute (TGen) today announced finding a novel recurring mutation of the gene AKT1 in breast, colorectal and ovarian cancers.

New model for signal transduction in cells

Among the key communication systems within a cell is the Wnt signaling pathway, which regulates embryonic development and whose deregulation can also contribute to cancer development.

Scientists discover a new line of communication between nervous system cells

In a host of neurological diseases, including multiple sclerosis (MS) and several neuropathies, the protective covering surrounding the nerves - an insulating material called myelin - is damaged.

New insight into the mechanism by which glial cells recognize and myelinate axons

In a host of neurological diseases, including multiple sclerosis (MS) and several neuropathies, the protective covering surrounding the nerves - an insulating material called myelin - is damaged.

RNA polymerase points to new targets for drug design

Researchers at UAB (University of Alabama at Birmingham) have new information on the structure of a key enzyme in bacteria that could lead to improved antibiotics and less antibiotic resistance.

Why the cold hurts - research has implications for pain relief

Freeing knotted shoelaces with fingers that are frozen stiff is extremely difficult and can even be painful.

New targets for Leishmaniasis

A comparison of three parasite species that cause Leishmaniasis has identified a small number of genes, many new to biology, that will provide a framework to target the search for new treatments.

Alzheimer's-associated enzyme beta-secretase can disrupt neural activity in the brain

An enzyme involved in the formation of the amyloid-beta protein associated with Alzheimer's disease can also alter the mechanism by which signals are transmitted between brain cells, the disruption of which can cause seizures.

Scientists extend life of fruit fly

In a triumph for pests, scientists have figured out how to make the fruit fly live longer.

New contributor to aggressive cancers

Mutations in the cell adhesion molecule known as integrin alpha 7 (integrin 7) lead to unchecked tumor cell proliferation and a significantly higher incidence in cancer spread, or metastasis, in several cancer cell lines, report researchers at the University of Pittsburgh School of Medicine in a study published in the Journal of the National Cancer Institute.

HIV uses pathways to infect cells

Like hobos on a train, HIV, the virus that causes AIDS, uses a pre-existing transport system to leave one infected cell and infect new ones, Hopkins scientists have discovered.

Molecular motors may speed nutrient processing

Matthew Tyska, Ph.D., recalls being intrigued, from the first day of his postdoctoral fellowship in 1999, with a nearly 30-year-old photograph.

Potential therapeutic target for autoimmune vasculitis

A potential therapeutic target for autoimmune vasculitis has been identified by researchers of the Franz Volhard Clinic for Cardiovascular Diseases (FVK) of the Charity – University Medicine Berlin/HELIOS-Klinikum and the Max Delbruck Center for Molecular Medicine (MDC) Berlin-Buch.
