Within all our cells lies two meters of DNA, highly ordered in a structure of less than 10 micro meters in diameter. Special proteins called histones act as small building bricks, organising our DNA in this structure. Preservation of the structure is necessary to maintain correct function of our genes, making histones detrimental for maintaining a healthy and functional body. The research group of Associate Professor Anja Groth from BRIC, University of Copenhagen, has just elucidated a...

The disparity in stroke-related deaths among black and white children dramatically narrowed after prevention strategies changed to include ultrasound screening and chronic blood transfusions for children with sickle cell anemia, according to research presented at the American Stroke Association's International Stroke Conference 2012. Before stroke prevention efforts changed in 1998, black children were 74 percent more likely to die from ischemic strokes than white children. This gap is in...

Young infants and toddlers with sickle cell anemia who received the drug hydroxyurea were no more likely to have cellular genetic damage than those who received a placebo or inactive medicine, said researchers from Baylor College of Medicine in Houston and St. Jude Children's Research Hospital in Memphis, Tenn., yesterday at the American Society of Hematology's annual meeting in San Diego, Calif. These findings provide further evidence of the safety of hydroxyurea for children with sickle...

New research in the FASEB Journal suggests that EPO poses a risk to blood vessels in the brain and body Erythropoietin or EPO might be considered a "performance enhancing" substance for athletes, but new research published online in The FASEB Journal (http://www.fasebj.org) shows that these enhancements come at a high cost--increased risk of vascular problems in the brain. According to the study, short- or long-term use of EPO raises blood pressure by constricting arteries, which reduces...

New gene editing technique would heal patients with their own cells Researchers at the Salk Institute for Biological Studies have developed a way to use patients' own cells to potentially cure sickle cell disease and many other disorders caused by mutations in a gene that helps produce blood hemoglobin. The technique uses cells from a patient's skin to generate induced pluripotent stem cells (iPSCs), which are capable of developing into various types of mature tissues -- including...

A team of researchers from the Johns Hopkins Children´s Center, Vanderbilt University and elsewhere have demonstrated that high blood pressure and anemia together put children with sickle cell disease (SCD) at serious danger for symptomless or so-called “silent” strokes, although either condition alone also signaled high risk. The results are part of an ongoing NIH-funded international multicenter trial, believed to be the largest study of its kind to date in children with...

Malaria Parasite Discovery May Lead To Vaccine

[ Watch the Video ] Researchers have revealed a new discovery in understanding how a malaria parasite invades human red blood cells. The team from the Wellcome Trust Sanger Institute said they found that the parasite relies on a single receptor on the red blood cell's surface to invade. Malaria kills about a million people every year, most of them being children in Africa under the age of five. The blood stage of the parasite's lifecycle starts when it invades human red blood...

Laboratory study at University of Michigan Health System shows increasing TR2/TR4 expression can lead to higher fetal hemoglobin levels in sickle cell patients A University of Michigan Health System laboratory study reveals a key trigger for producing normal red blood cells that could lead to a new treatment for those with sickle cell disease. The study, conducted in mice, appears in this week's early edition of the Proceedings of the National Academy of Sciences, and holds promise for...

Professor Qin Wenbin from BaoTou Medical College first identified the hemoglobin (Hb) A2 phenomenon 30 years ago. His first paper on this phenomenon was published in Acta Biochimica et Biophysica Sinica, in Chinese, in 1981. Subsequent research investigating its mechanism was published in Chinese in the Chinese Biochemical Journal and Progress in Biochemistry and Biophysics in 1991 and more recently in Electrophoresis, in 2010. Using electrophoretic methods, he discovered that Hb is...
