Scientists deconstruct cell division

The last step of the cell cycle is the brief but spectacularly dynamic and complicated mitosis phase, which leads to the duplication of one mother cell into two daughter cells.

Discovery of mechanism that may explain Parkinson's and other neurological disorders

Studying just eight families worldwide, the international team of researchers have discovered a genetic defect that results in profound depression and parkinsonism in a disorder known as Perry syndrome.

Potential gene target for treatment of common hearing, vertigo and balance problems

A UCLA study shows for the first time how microscopic crystals form sound and gravity sensors inside the inner ear.

Key factor in brain development revealed, offers insight into lissencephaly

In the earliest days of brain development, the brain's first cells - neuroepithelial stem cells - divide continuously, producing a population of cells that eventually evolves into the various cells of the fully formed brain.

Tug of war in the cells

Transport processes in the cells of our body resemble the transport of goods on the roads.

Alzheimer's molecule is a smart speed bump on the nerve-cell transport highway

Researchers at the University of Pennsylvania School of Medicine discovered that proteins carrying chemical cargo in nerve cells react differently when exposed to the tau protein, which plays an important role in Alzheimer's disease.

Mutations in a protein called dynein may cause inherited neuropathy

Mutations in a protein called dynein, required for the proper functioning of sensory nerve cells, can cause defects in mice that may provide crucial clues leading to better treatments for a human nerve disorder known as peripheral neuropathy, which affects about three percent of all those over age 60.

Discovery of new cellular mechanism behind Lou Gehrig's disease

University of Kentucky researchers have discovered a new cellular mechanism that may better explain what causes amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's Disease.

Discovery may change thinking on how viruses invade the brain

A molecule thought crucial to ferrying the deadly rabies virus into the brain, where it eventually kills, apparently isn't.

Myosin VI can act as molecular transporter

Myosin VI has been thought to be a monomer, but Park et al. show that full-length myosin VI can be a dimer, and can walk processively on actin. By increasing the concentration, a greater and greater fraction dimerizes in vitro, and walks processively on actin.

New clue to the causes of neurodegenerative diseases

Scientists funded by the Medical Research Council (MRC), the Wellcome Trust, BBSRC - the Biotechnology and Biological Sciences Research Council and the EU have made an important discovery about the mechanisms underlying degenerative brain diseases.

Molecular motors cooperate in moving cellular cargo

Researchers using an extremely fast and accurate imaging technique have shed light on the tiny movements of molecular motors that shuttle material within living cells. The motors cooperate in a delicate choreography of steps, rather than engaging in the brute-force tug of war many scientists had imagined.

Single abnormal cell can duplicate to form cancerous tumors

Researchers at the University of Pittsburgh have identified how a single aberrant cell can duplicate to form cancerous tumors, suggesting a specific protein mechanism as a target for the treatment of cancer, they report in a paper titled "Spindle Multipolarity Is Prevented by Centrosomal Clustering," published in the Jan. 7 issue of Science.

New target to stop breast cancer growth

Two proteins that normally help cells move from place to place and are made in large quantities in breast cancer cells work together to promote the survival and spread of breast cancer, according to a new study by scientists at The University of Texas M. D. Anderson Cancer Center.
