Scientists find mechanisms controlling metastasis of breast cancer cells

When cancer cells dissociate from the original tumor and migrate via the blood stream to colonize distant organs, is the main cause of cancer death.

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.

Phase II study of TroVax vaccine in patients with metastatic colorectal cancer

A therapeutic cancer vaccine has shown effectiveness when given alongside chemotherapy to patients with metastatic colorectal cancer in a phase II trial, according to researchers at Oxford BioMedica (UK) Ltd.

Cell injury caused by brushing may help keep gums healthy

One way regular brushing may help keep gums firm and pink is, paradoxically, by tearing open cells, researchers have found.

Drugs designed to disable enzyme TOPK could have anti-cancer benefits

Working with human colorectal cancer cells, a University of Minnesota team, led by cancer biologists Zigang Dong and Ann Bode, has found the potential culprit among a network of enzymes that relay signals inside cells to regulate such functions as cell growth, cancer development and programmed cell death.

Imaging technique accurate in aneurysm detection and therapy planning

Multidetector computed tomography (MDCT) angiography is highly accurate in depicting intracranial aneurysms, according to a study published in the August issue of Radiology.

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.

Novel bioreactor to repair vocal chords

Damaged or diseased vocal cords can forever change and even silence the voices we love, from a family member's to a famous personality's.

New findings on how brain processes visual information

Neuroscientists have long believed that vision is processed in the brain along circuits made up of neurons, similar to the way telephone signals are transferred through separate wires from one station to another.

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.

Essential fatty acid intake drops as alcohol consumption increases, particularly among men

Essential fatty acids (EFAs) are just that; an "essential" part of the total fat intake necessary for a healthy human diet. Most EFAs come from plants, but some are animal-sourced.

Nicotine rush hinges on sugar in neurons

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

New understanding of how anaesthetics work in the brain

An important clue to how anaesthetics work on the human body has been provided by the discovery of a molecular feature common to both the human brain and the great pond snail nervous system, scientists say today.

New method of adult stem cell therapy to grow cornea stem cells

A new method of adult stem cell growth, designed in the Area of Cellular Therapy of the University Clinic (University of Navarra), has demonstrated its efficacy for its capacity to grow cornea stem cells.

Insights into side effects of HIV protease inhibitors

UCLA scientists, along with collaborators from Purdue University, have demonstrated that HIV protease inhibitors, crucial drugs for HIV treatment block a cellular enzyme important for generating the structural scaffolding for the cell nucleus.

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.

Structural basis for synthesis of inflammatory mediators by human leukotriene C4 synthase

Researchers at Karolinska Institutet in Sweden have managed to elucidate the crystal structure of a human membrane protein - LTC4 synthase - which has a major influence on the development of asthma.

Eye lens and nose cells for smelling have same origin

A team of researchers at Umeå University in Sweden have discovered a unique mechanism by which the same signal molecule determines the formation of the both the lens of the eye and the olfactory cells of the nose.
