Whitehead Institute researchers have identified a previously unrecognized layer of genetic regulation that is necessary for the generation of undesirable white fat cells. When this regulation is disrupted, white fat cells are unable to accumulate lipid droplets or mature from their precursors. "We're trying to figure out what the mechanism is–what it takes to make fat cells," says Whitehead Founding Member Harvey Lodish, who is also a professor of biology and a professor of...

Malaria in pregnancy causes a range of adverse effects, including abortions, stillbirths, premature delivery and low infant birth weight. Many of these effects are thought to derive from a placental inflammatory response resulting from interaction of infected red blood cells with the placental tissue. In a study published in the latest issue of the journal PLOS Pathogen, a researchers' team led by Carlos Penha-Gonçalves at the Instituto Gulbenkian de Ciência (IGC),...

Sickle-shaped red blood cells target and destroy tumor cells and blood vessels The genetic mutation that causes sickle cell anemia also turns red blood cells into potent tumor killers and may offer a new way to treat some cancers that are resistant to existing treatments, according to research published January 9 in the open access journal PLOS ONE by David S. Terman of Jenomic Research Institute and colleagues from Duke University and other institutions. The mutation that causes sickle...

Convergent Evolution Linked To Adaptation To High Altitudes

April Flowers for redOrbit.com - Your Universe Online A shared biological adaptation enables highlanders in both Tibet and Ethiopia to thrive in the low oxygen of high altitudes. A new study from Case Western Reserve University reveals that the ability to pass on this trait, however, appears to be linked to different genes in the two groups. The shared adaptation is the ability to maintain relatively low levels of hemoglobin for high altitudes. Hemoglobin is the oxygen-carrying protein...

Researchers at Duke University Medical Center may finally have discovered why people with sickle cell disease get milder cases of malaria than individuals who have normal red blood cells. In a finding that has eluded scientists for years, Duke researchers discovered that genetic material in red blood cells may help alter parasite activity via a novel mechanism that alters parasite gene regulation. "One of the most interesting findings in our study is that the human microRNA (very small...

A team of scientists from Albert Einstein College of Medicine in Bronx, NY, has developed methods to increase the production of red blood cells from stem cells, a discovery that could dramatically boost the blood supply available for transfusions. In the latest issue of STEM CELLS Translational Medicine, researchers Eric Bouhassira, Emmanuel Oliver, and Caihong Qiu published data on a promising new method of growing red blood cells in the lab. Durham, NC (PRWEB) August 02, 2012 A team of...

Eltrombopag, a drug that was designed to stimulate production of platelets from the bone marrow and thereby improve blood clotting, can raise blood cell levels in some people with severe aplastic anemia who have failed all standard therapies. About one-third of aplastic anemia cases do not respond to standard therapy, a combination of immune-suppressing drugs. Although bone marrow stem cell transplantation is an option for some, patients without a matched donor have few treatment options....
