Genomic screen identifies 273 human proteins required for HIV propagation

In some ways, HIV resembles a minimalist painter, using a few basic components to achieve dramatic effects.

Genetic evolution of tumours according to their growth dynamics.

A study co-directed by the Universidad Complutense de Madrid and La Paz hospital in Madrid identifies a protein of high expression in cells located at the tumour boundary that could play an essential role in the evolution of tumours and their invasive potential.

Chemical first found on Easter Island could treat tuberous sclerosis

A new study has shown promising results in fighting a severe genetic disorder which can create tumours throughout the body.

Asf1, the protein that oversees DNA replication and packaging in the cell

At the Institut Curie, the CNRS team of Genevieve Almouzni has just discovered how the protein Asf1 ensures the correct (re)organization of duplicated DNA. During DNA replication, all the information in the mother cell must be transmitted to the daughter cells.

Scientists identify cells that promote formation of lethal lung metastases

Cancer patients usually ask what can be done after a primary tumor has already spread, or metastasized, to other organs.

Body's immune system uses common molecule to recognize prostate tumors

In experiments with mice, researchers have found that the body's immune system can use a surprisingly common molecule to recognize prostate tumors.

Discovery of gene variant that raises autism risk

Scientists have found a variation in a gene that may raise the risk of developing autism, especially when the variant is inherited from mothers rather than fathers.

New way to boost red blood cell numbers

A common treatment for anemia a deficiency in red blood cells (rbcs) caused by their insufficient production, excessive destruction, or excessive loss is administration of recombinant erythropoietin (Epo), a hormone that stimulates the production of rbc precursors by the bone marrow.

A few more pieces for the puzzle that is Alzheimer’s disease

Alzheimer's disease (AD) affects as much as 10% of the world population above 65 years of age but after years of research it is still not understood exactly how the disease appears and, even less, how to treat it.

Does cholesterol have any benefits?

If you're worried about high cholesterol levels and keeping heart-healthy as you get older, don't push aside bacon and eggs just yet. A new study says they might actually provide a benefit.

Small pieces of ribonucleic acid prevent spread of breast cancer

Howard Hughes Medical Institute researchers have identified small pieces of ribonucleic acid (RNA) that suppress the spread of breast cancer to the lungs and bone.

Morphotek announces agreement for development of antibodies to treat prostate cancer

Morphotek, Inc., a subsidiary of Eisai Co., Ltd., has announced that it has signed a Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute (NCI) for the development of therapeutic antibodies to a cancer-associated protein identified by NCI researchers.

Huntington's disease problem starts early

The damaging effects of the mutated protein involved in Huntington's disease take place earlier in cell life than previously believed, said researchers from Baylor College of Medicine in Houston in a report that appears in the current edition of the journal Neuron.

New phenylketonuria (PKU) treatment offered at Hayward Genetics Center

No pizza. No ice cream. No hotdogs and definitely no hamburgers. What sounds like a list of banned food for someone trying to lose weight is actually a way of life for children with a rare metabolic disorder, phenylketonuria (PKU), which prevents digestion of an essential amino acid found in most meats, eggs, dairy products, nuts and breads.
