Haitian cholera pathogen closely related to 'El Tor O1' variant from South Asia

Scientists from Pacific Biosciences of California, Inc. and Harvard Medical School have successfully employed single molecule, real-time (SMRT™) DNA sequencing technology to rapidly characterize the pathogen responsible for the recent deadly cholera epidemic in Haiti. Published online Thursday in the New England Journal of Medicine, the results provide the first whole genome sequence analysis and most detailed genetic profile to date of the Haitian Vibrio cholerae outbreak strain.

Study compares efficacy of two treatments for iron overload caused by chronic transfusion therapy

Monthly blood transfusions combined with daily medication to remove the resulting excess iron remains the best approach for reducing the risk of recurrent strokes in young patients with sickle cell anemia, according to a preliminary analysis of a multicenter trial that includes St. Jude Children's Research Hospital.

Personal environment influences effects of genes and risk of disease

Personalized medicine centers on being able to predict the risk of disease or response to a drug based on a person's genetic makeup. But a study by scientists at Washington University School of Medicine in St. Louis suggests that, for most common diseases, genes alone only tell part of the story.

Drugs that target DNA in later-stage cancers could be effective in treating breast tumors

Breast cancers that arise sporadically, rather than through inheritance of certain genes, likely start with defects of DNA repair mechanisms that allow environmentally triggered mutations to accumulate, according to researchers at the University of Pittsburgh School of Medicine, Magee-Womens Hospital of UPMC and the University of Pittsburgh Cancer Institute.

Overexpression of microRNA 125b can cause leukemia: Research

Whitehead Institute researchers have shown in mouse models that overexpression of the microRNA 125b (miR-125b) can independently cause leukemia and accelerate the disease's progression. Their results are published in this week's online edition of the Proceedings of the National Academy of Sciences (PNAS).

Research on fruit flies reveal novel human pain gene

While it has become clear in recent years that susceptibility to pain has a strong inherited component, very little is known about actual "pain genes" and how they work. In the November 12th issue of Cell, researchers at Children's Hospital Boston and their collaborators report on a novel human pain gene. People with minor variations in this gene showed clear differences in susceptibility to acute heat pain and chronic back pain.
