Listeria pathogen may be key to understanding cancer development

A research team including University of Central Florida Microbiology Professor Keith Ireton is using the bacterial pathogen Listeria Monocytogenes to understand the mechanisms of cell growth and cancer development.

Indian medicinal plant effective in blocking blood-vessel and tumor growth

Researchers at the University of Kentucky have advanced research of a natural product found in an Indian medicinal plant that has shown effectiveness in blocking blood-vessel and tumor growth.

Novel cellular mechanism that may guide cell movement and possibly cancer cell invasion

Scientists have long thought that microtubules, part of the microscopic scaffolding that the cell uses to move things around in order to hold its shape and divide, originated from a tiny structure near the nucleus, called the centrosome.

Stress and Alzheimer's disease

Subjecting mice to repeated emotional stress, the kind we experience in everyday life, may contribute to the accumulation of neurofibrillary tangles, one of the hallmarks of Alzheimer's disease, report researchers at the Salk Institute for Biological Studies.

Scientists have captured on video the intracellular version of a postal delivery service

Reporting in the journal Biochemical and Biophysical Research Communications (BBRC), bioengineering researchers at UC San Diego published videos of a key message-carrying protein called paxillin moving abruptly from hubs of communication and transportation activity on the cell surface toward the nucleus.

First comprehensive profile of cell movement

Researchers at the University of California, San Diego (UCSD) School of Medicine have developed new technology which, combined with proteomics, the large-scale study of the structure and function of proteins and their functions, has allowed them to map an extensive network of the signaling proteins that control cell movement.

Important step towards a spatially and temporally quantifiable model of the cell

Cell membranes are like two-dimensional fluids whose molecules are distributed evenly through lateral diffusion.

Cell structures exhibit novel behaviors, mimic red blood cells and liquid crystals

Researchers at the University of Pennsylvania and Yale University have manipulated the internal, structural components of cells, creating a set of simulated cellular structures with novel mechanical properties, including one that acts like a red blood cell and another that mimics the soft, elastic behavior commonly found in novel synthetic materials called liquid crystal elastomers.

Researchers create roadmap to integrin activation

Calling it an important technical advance in the study of the complex receptors and pathways of the body's cellular system, researchers at the University of California, San Diego (UCSD) School of Medicine have reconstructed the signaling pathways that impact activation of a receptor that is critical to the control of bleeding and to the thrombosis that occurs in heart attacks and strokes.

Study shows how the plague bacteria Yersinia pestis causes disease

The bacteria responsible for the plague and some forms of food poisoning "paralyze" the immune system of their hosts in an unexpected way, according to a new study in the September 8, 2006 issue of the journal Cell.

Research illustrates BAG3 protein's importance in maintaining mature skeletal muscle

Muscle cells that should grow stronger with use instead self-destruct when a protein called BAG3 isn't around, researchers have shown.

Mechanics of atherosclerosis

Atherosclerotic narrowing and hardening of coronary arteries typically appear first at vessel branches, and a study in the October issue of Cellular Signalling reports that the type of mechanical stretching found at those branches activates a cellular protein known to damage cells.

Bedsores and bald hides: novel roles revealed for a "scaffolding" protein

A protein long thought to provide only mechanical support for keeping cells and tissues from literally falling apart turns out to have much wider utility.

Inhibiting cell process may give cancer drug a boost

A molecule that interferes with the internal scaffolding that shapes the cell may kill cancer cells, retard the growth of tumors and give a boost to a common chemotherapy drug, according to findings appearing in the May 3 issue of the European Journal of Cancer.

Cause and treatment for aggressive head and neck cancer may have been found

Researchers report that they have found a potential molecular cause for the aggressive growth and spread of human head and neck squamous cell carcinoma, a highly malignant form of cancer with a very high death rate.

Scientists gain greater understanding of how embryos differentiate left from right

Researchers at the Forsyth Institute have discovered a new mechanism responsible for early left/right patterning, the process by which organs locate themselves on the left or right side of the body.

Penn researchers study link between potassium and sodium channels aiming at new treatments for neurological diseases

Researchers at the University of Pennsylvania School of Medicine have discovered the mechanism that facilitates how two ion channels collaborate in the control of electrical signals in the brain.

Researchers identify protein essential for the maintenance of synapses

Nerve cells store and transmit information via special contact sites called synapses. Synapses also play a role in determining what we remember and what we forget.

Fear gene discovered

In the Nov. 18 issue of Cell, researchers report the discovery of a gene that controls the ability to react with appropriate fear to impending danger.

Scientists gain better understanding of how repetitive stretching of endothelial cells that line arteries can make them healthy and resistant to vascular diseases

UCSD researchers stretched cells in a workout chamber the size of a credit card to gain a better understanding of how repetitive stretching of endothelial cells that line arteries can make them healthy and resistant to vascular diseases.
