New key mechanism in cell division discovered

Scientists at the IFOM-IEO Campus have revealed the function of a protein that is indispensable for passing on an accurate copy of the genome from mother to daughter cells. This study, published in Cell, opens up new avenues of research to reduce the toxicity of chemotherapy in the treatment of cancer.

Research reveals workings of anti-HIV drugs

Using ingenious molecular espionage, scientists have found how a single key enzyme, seemingly the Swiss Army knife in HIV's toolbox, differentiates and dynamically binds both DNA and RNA as part of the virus's fierce attack on host cells. The work is described this week (May 7) in the journal Nature.

Scientists discover how reverse transcriptase molecules interact with the HIV genome

Using ingenious molecular espionage, scientists have found how a single key enzyme, seemingly the Swiss army knife in HIV's toolbox, differentiates and dynamically binds both DNA and RNA as part of the virus' fierce attack on host cells. The work is described this week in the journal Nature.

Genetic tag team orchestrates the cell cycle

By surveying the activity of thousands of genes at several different time points, researchers at the Duke Institute for Genome Sciences & Policy have uncovered new evidence that a network of influential genes act as a kind of genetic tag team to orchestrate one of the most fundamental aspects of all life: the cell cycle.

Discovery of DNA variations in chromosome 6 that gives rise to neuroblastoma

Using advanced gene-hunting technology, an international team of researchers has for the first time identified a chromosome region that is the source of genetic events that give rise to neuroblastoma, an often fatal childhood cancer.

Superbug genome sequenced

The genome of a newly-emerging superbug, commonly known as Steno, has just been sequenced. The results reveal an organism with a remarkable capacity for drug resistance. The research was carried out by scientists at the Wellcome Trust Sanger Institute near Cambridge and the University of Bristol.

New chemicals shield 'genome guardian'

Cancer Research UK scientists have discovered a potent group of chemicals that protect p53 - a major anti-tumour gene - from destruction, a study published in Cancer Cell* today (Monday) reveals.

FGFR2 gene increases susceptibility to breast cancer

Much work has been done to identify genetic variations that predispose women to breast cancer. Previous work showed that variants in the gene called fibroblast growth factor receptor 2 (FGFR2) were associated with increased risk of the disease, but how these variants translated into increased risk was unknown.

Most comprehensive kinome collection

Scientists from University of Helsinki, Institute of Molecular Medicine in Finland and OriGene Technologies joined effort in creating the most comprehensive kinome collection of nearly all predicted human protein kinases, including the functional kinases and their kinase-deficient counterparts. Equipped with this collection, the authors successfully identified novel kinase regulators in Hedgehog signaling pathway and in activation of Karposi's Sarcoma herpesvirus.

Whole-organ genomic survey depicts journey from normal to malignant cell

Whole-organ maps that superimpose genetic information over the terrain of cancerous bladders chart the molecular journey from normal cell to invasive cancer, an international research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports online at the journal Laboratory Investigation.

Drinking patterns in adolescents may be set after only a few exposures to alcohol

Scientists at Duke University Medical Center have shown a connection between early drinking patterns and a tendency to be a heavy drinker in adulthood, in a study of adolescent rats.

Researchers report the cloning of a key group of human genes, the protein kinases

Although the human genome has been sequenced, research into mechanism of action of genes has been hampered by the fact that most human genes have not been isolated.

First sequence-based map of large-scale structural variation across the human genome

A nationwide team of researchers, funded in part by the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), has produced the first sequence-based map of large-scale structural variation across the human genome. The work, published today in the journal Nature, provides a starting point to examine how such DNA variation contributes to human health and disease.

Human protein may offer novel target for blocking HIV infection

A research group supported by the National Institutes of Health (NIH) has uncovered a new route for attacking the human immunodeficiency virus (HIV) that may offer a way to circumvent problems with drug resistance. In findings published today in the online edition of the Proceedings of the National Academy of Sciences, the researchers report that they have blocked HIV infection in the test tube by inactivating a human protein expressed in key immune cells.
