Computer science sheds light on animal development

By applying the techniques of computer engineering to a mechanistic diagram describing the development of the Nematode C. elegans, a group of researchers in Switzerland has been able to tease out what laboratory experiments have not how and when the crucial cross-talk between cellular signaling pathways takes place in order to determine the fates of individual cells.

Celecoxib offers promise for premature babies

Scientists have found evidence that the cox-2 inhibitor celecoxib, a common pain reliever used to treat arthritis, may offer a new way to reduce the risk of the most common cause of brain damage in babies born prematurely.

Some NSAIDs may be better suited to treating cancer

Until recently, nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin and celecoxib (sold as Celebrex), were being hailed as promising cancer prevention drugs.

Quest for effective HIV vaccines present new possibilities, challenges

A vaccine that prevents HIV infection remains an important goal in the fight against AIDS, but the current top HIV vaccine candidates may not work in this way, say scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH).

Health effects of isoflavones and breast cancer

Are soy products healthy additions to a person's diet, safe alternatives to hormone-replacement therapy or cancer-causing agents" The answer, according to University of Illinois food science and human nutrition professor William Helferich, is, "It depends."

Researchers identify the cancer stem cell for rhabdomyosarcoma

As published in the June 1 issue of Genes & Development, Dr. Leonard Zon (Children's Hospital Boston) and colleagues have identified the cancer stem cell for rhabdomyosarcoma, the most common soft-tissue sarcoma of childhood.

Nutrition and heredity genetically linked

A challenging goal in biology is to understand how the principal cellular functions are integrated so that cells achieve viability and optimal fitness under a wide range of nutritional conditions.

Important new gene-silencing mechanism

Genes provide the instructions used by the individual cells to produce the many different proteins that make up the body.

Clearer view of synaptic plasticity

Scientists are keenly studying how neurons form synapses--the physical and chemical connections between neurons--and the "pruning" of neural circuits during development, not least because synaptic abnormalities may partially underlie many developmental and neurodegenerative diseases.

New findings on microRNAs

Over 30% of our genes are under the control of small molecules called microRNAs.

Implanting dopamine generators in brain cells improves Parkinson's in monkeys

Implanting dopamine generators (dopaminergics) in brain cells has produced improvement in the symptoms in Parkinson's, according to the results of tests carried out with monkeys by the Navarra University Hospital, led by Dr Mar'a Rosario Luquin Piudo, neurologist at the Hospital and at the other Navarra University-based medical centre, CIMA (the Research Centre for Applied Medicine).

Culture techniques can significantly affect cell growth and function

When it comes to growing cells in a lab, technique matters. A new Brown University study shows that nerve cells grown in three-dimensional cultures use 1,766 genes differently compared to nerve cells grown in standard two-dimensional petri dishes.

Increase in fatal car crashes involving young women

Automobile crashes remain the leading cause of death for adolescents and young adults, compounded by the effects of alcohol and failure to use seatbelts.

Promoter hypermethylation is common in breast cancer

Cancer epidemiologists at the University at Buffalo have identified specific genes that are most likely to become cancer promoters when exposed to a process called DNA promoter hypermethylation.

Project aims to develop stem cell lines that genetically match human patients

These lines would allow scientists to better study conditions ranging from diabetes to Parkinson's disease, and they would provide the basis for potential patient-specific stem cell treatments.

Yin Yang 1 regulates early B cell development

A new paper in the May 15th issue of Genes & Development reveals how a protein called Yin Yang 1 regulates early B cell development.

Study revises dynamin's role in nerve cell function

An unexpected finding on how nerve cells signal to one another could rewrite the textbooks on neuroscience, says a collaborative team of researchers at Weill Cornell Medical College and Yale University.

Cancer cells can be killed by a new cancer drug that is triggered by a laser light

Their paper describes how these new photosensitizer drugs can only be activated by light once they have been localized in the target tumour cells. For the first time Zheng and Wilson have demonstrated that tumour cells can be selectively attacked using a PDT.

Model of proline dehydrogenase created

Researchers at the University of Missouri-Columbia recently created a model of proline dehydrogenase, an important cancer-preventing enzyme in the human body, and analyzed how it works.
