New inhibitor has potential as cancer drug
Laboratory experiments have previously shown that cancer cells overproduce an enzyme, heparanase, which splits the body's own polysaccharide heparan sulfate into shorter fragments. view more (2007-10-23)
A new system for collaboration in cell communication
Investigators from the Institute of Research in Biomedicine (IRB Barcelona) have identified a new signalling mechanism among cells in the fruit fly, Drosophila melanogaster. view more (2007-06-27)
A resetting signal keeps circadian rhythm on track in Drosophila fruit flies
A Brandeis University study published this week in Nature shows for the first time that a molecular signal maintains coherence among brain clock cells that regulate daily activity of Drosophila melanogaster (fruit flies). view more (2005-11-10)
Cell survival depends on chromosome integrity
As part of a large National Institutes of Health-funded Technology Centers for Networks and Pathways project, Johns Hopkins researchers have discovered protein machinery important for cells to keep chromosomes intact. view more (2006-07-10)
A miR boost enables acute leukemia cells to mature
A new study by Ohio State University cancer researchers shows that boosting the level of a molecule called miR-29b in acute myeloid leukemia (AML) cells can reverse gene changes that trap the cells in an immature, fast growing state of development. view more (2009-04-03)
DFG remains skeptical of the cloning of human cells
According to a paper published in the journal Stem Cells, an American group has succeeded in inserting cell nuclei from human skin cells into human enucleated oocytes and to stimulate these new cells to undergo cell division in the laboratory. view more (2008-01-23)
Hope For New Meningitis Vaccine
Research performed by scientists at the School of Biomedical and Molecular Sciences, University of Surrey and the Health Protection Agency (Porton Down, Salisbury) provides hope for developing a new meningitis vaccine that will protect children against all groups of meningococcus. Published in the journal, Infection and Immunity, the research... view more... (2004-01-05)
Genome research centre opens on University of Sussex campus
Eight teams of cancer researchers have moved into the first research laboratory to be built on the University of Sussex campus for 30 years. Researchers in the purpose-built Genome Damage and Stability Centre are working on the human body's most precious possessions - genomes - which contain the genetic blueprint that tells every part of the body... view more...

Schizophrenia risk highest in small ethnic groups
The rate of schizophrenia among people from non-white ethnic groups rises as the proportion of these groups fall in the local population, finds a study in this week's BMJ. view more (2001-12-05)
Penn study points to new direction for pancreas cell regeneration
Replacing faulty or missing cells with new insulin-making cells has been the object of diabetes research for the last decade. Past studies in tissue culture have suggested that one type of pancreas cell could be coaxed to transform into insulin-producing islet cells. view more (2007-04-04)
Human Cytomegalovirus May Be Involved In Colorectal Cancer (p 1557)
Preliminary findings of a study in this week's issue of THE LANCET suggest that a common human virus may play a part in the cellular processes involved in the development of colorectal cancer. Colorectal cancer is the second most frequent cause of death from cancer in many developed countries; most tumours arise sporadically with no clear cause... view more... (2002-11-13)
Caring for older people with dementia
The plight of older people from ethnic minority groups who develop dementia and how to ensure they get what they need from the NHS was discussed by psychologists from across the UK when they met at the Annual Conference of the Psychologists Special Interest Group Working with Older People (PSIGE) today, Friday 12 July, at King Alfred’s... view more...

Great potential for new success in Swedish stem cell research
Swedish stem cell researchers are in a good position to become even more successful than in recent years. This can be achieved by improving the collaboration between research groups, and by increasing the number of researchers in the field through, for example, the introduction of "come-home" grants for those who have been abroad.... view more...

Human ES cells progress slowly in myelin's direction
Scientists from the University of Wisconsin, USA, report in the journal Development the successful generation from human embryonic stem cells of a type of cell that can make myelin, a finding that opens up new possibilities for both basic and clinical research. view more (2009-04-09)
Potential preventative therapy for Type 1 diabetes
Scientists believe they may have found a preventative therapy for Type 1 diabetes, by making the body's killer immune cells tolerate the insulin-producing cells they would normally attack and destroy, prior to disease onset. view more (2009-04-29)
Press conference - Public Perspectives on Human Cloning
Scientists have spoken about cloning; regulatory bodies are considering their positions; Ministers will in due course give their pronouncements - but what does the public feel about cloning? The truth is that the public have grave worries about a future society in which reproduction can occur without the need for men. view more (1998-12-01)
Children's peer victimization -- a mix of loyalty and preference
New research into childhood prejudice suggests that loyalty and disloyalty play a more important role than previously thought in how children treat members of their own and other groups. view more (2007-11-12)
Silenced genes as a warning sign of blood cancer
In many types of cancer, parts of the genetic material of tumor cells are switched off by chemical labels called methyl groups. This kind of methyl labeling ranges among the epigenetic changes that do not change the sequence of DNA building blocks. view more (2009-08-05)
SIRT1 takes down tumors
Yuan et al. have identified another anti-cancer effect of the "longevity" protein SIRT1. By speeding the destruction of the tumor promoter c-Myc, SIRT1 curbs cell division. view more (2009-04-13)
Redefining obesity's health risks
The body mass index (BMI) has long been the yardstick in deciding who is at risk because of their weight. BMI is essentially a measure of density, identifying 'under-' and 'over-weight' risk groups. view more (2009-10-20)
