Leaky membranes: Another sign of old age

As parts of us age, even the membrane bound nuclei , which house the genetic instructions for life that are "written" in our DNA, begin to show considerable wear and tear, suggests a new report in the January 23rd issue of the journal Cell, a Cell Press publication.

Stem cells could be used for personalized cancer treatment

Using cancer cells from an ovarian cancer patient and human embryonic stem cells, Israeli researchers have created a cancerous tumor in a mouse that mimics the way the tumor would develop in the patient's body.

New cellular clues to understanding cancer

In the 13th January print edition of the journal Current Biology, Instituto Gubenkian de Ciencia researchers provide insight into an old mystery in cell biology, and offer up new clues to understanding cancer.

Stem cells may 'ignite' bowel cancer development

Cancer Research UK scientists have discovered for the first time that stem cells could be the root cause of bowel cancer, according to a study published in Nature.

Mouse model shows blood stem cells in action

Over a period of five years, scientists at the Johannes Gutenberg University Mainz have managed to create a genetically modified mouse in which the activity of the blood stem cells can be tracked.

Biologist provides new theory on mechanisms that control molecular motors

Biologists have known for decades that cells use tiny molecular motors to move chromosomes, mitochondria, and many other organelles within the cell, but no one has been able to understand what "steers" these engines to their destinations.

Scientists create first functional stem-cell niche model

Like it or not, your living room probably says a lot about you. Given a few uninterrupted moments to poke around, a stranger could probably get a pretty good idea of your likes and dislikes, and maybe even your future plans.

New discovery on cell division could improve chemotherapies for cancer

Researchers from the Ludwig Institute for Cancer Research at the University of California, San Diego School of Medicine have identified a key step required for cell division in a study that could help improve therapies to treat cancer.

New insights into cell division

Biologists have discovered a mechanism that is critical to cytokinesis -- nature's completion of mitosis, where a cell divides into two identical daughter cells.

Dormant stem cells for emergencies

Many specialized cells, such as in the skin, intestinal mucosa or blood, have a lifespan of only a few days.

Discovery of new mechanism for cell division

A Swedish research group, partly financed by NWO, has discovered a new mechanism for cell division in a microorganism found in extremely hot and acidic conditions.

Scientists discover an important new layer of regulation in the cell division cycle

A Florida State University College of Medicine research team led by Yanchang Wang has discovered an important new layer of regulation in the cell division cycle, which could lead to a greater understanding of the way cancer begins.

Researchers reveal a new aspect of tumor development

The DNA in our cells is constantly under assault from oxygen, the sun's radiation and environmental stresses.

Protein enzyme BubR1 provides new understanding of processes behind cancer-cell survival and drug-resistance

A study of how one protein enzyme, BubR1, helps make sure chromosomes are equally distributed during mitosis might explain how the process of cell division goes so awry in cancer, according to researchers from Fox Chase Cancer Center.

Novel cell division mechanism discovered

A novel cell division mechanism has been discovered in a microorganism that thrives in hot acid. The finding may also result in insights into key processes in human cells, and in a better understanding of the main evolutionary lineages of life on Earth. The study is published today in the online version of the journal of the American National Academy of Sciences, PNAS.

Newly discovered mechanism can explain the Beckwith-Wiedemann syndrome

Researchers from Uppsala University have discovered a mechanism that silences several genes in a chromosome domain. The findings, published in today's on-line issue of Molecular Cell, have implications in understanding the human disorder Beckwith-Wiedemann syndrome.

A fitness test for DNA

Unusually high levels of physical exertion do cause oxidative stress, but this does not result in any long-term damage to DNA. This is just one of the many outcomes revealed by an extraordinary research project funded by the Austrian Science Fund FWF that are now published. As part of this project, 42 male athletes took part both in a triathlon and an extensive biomedical study, which examined numerous physiological values parameters during the period from two days before to 19 days after the triathlon.

Australian researchers reveal how cancers become more aggressive

A team of Australian scientists have discovered how some cancers are able to mutate into more aggressive and potentially fatal cancers in the human body.

11 Aug 2008

Cancer survival secrets discovered by Australian researchers

A team of Monash University researchers has uncovered the role of a family of enzymes in the mutation of benign or less aggressive tumours into more aggressive, potentially fatal, cancers in the human body.

Statins have unexpected effect on pool of powerful brain cells

Cholesterol-lowering drugs known as statins have a profound effect on an elite group of cells important to brain health as we age, scientists at the University of Rochester Medical Center have found. The new findings shed light on a long-debated potential role for statins in the area of dementia.
