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...

Scientists Discover New Possible Therapy For Sickle Cell Anemia
2011-10-14 06:12:19

Scientists, funded by the National Institutes of Health, have discovered a way to turn on the mechanism that creates fetal hemoglobin. Fetal hemoglobin is in the human body during the fetal stage of life up to around 3 to 6 months after birth. Scientists have known for years that increased levels of fetal hemoglobin reduce the onset of the misshapen blood cells that cause the symptoms of sickle cell anemia; symptoms include pain, strokes, organ dysfunction and premature death. The...

  The blood from woolly mammoths–those extinct elephant-like creatures that roamed the Earth in pre-historic times–is helping scientists develop new blood products for modern medical procedures that involve reducing patients' body temperature. The report appears in ACS' journal Biochemistry. Chien Ho and colleagues note that woolly mammoth ancestors initially evolved in warm climates, where African and Asian elephants live now, but migrated to the cold regions of...

A thalidomide analog is shaping up as a safe, worthy opponent of sickle cell disease, Georgia Health Sciences University researchers report. Much like hydroxyurea, the only Food and Drug Administration-approved therapy for sickle cell, pomalidomide increases production of fetal hemoglobin which, unlike its adult counterpart, cannot take on the destructive sickle shape. In stark contrast, pomalidomide also preserves bone marrow function actually increasing proliferation of the cells that make...
