Bypassing Stem Cells: Adult Skin Cells Turned Into Muscle Cells And Vice Versa
Thursday, April 30th, 2009Researchers are now able to reprogram human adult skin cells into other cell types in order to decipher the elusive mechanisms underlying reprogramming. To demonstrate their point, they transformed human skin cells into mouse muscle cells and vice versa.
Schizophrenia And Manic-depressive Disorder: Genetic Variant Impairs Communication Within Brain
Thursday, April 30th, 2009For some time now it has been known that certain hereditary factors enhance the risk of schizophrenia or a manic-depressive disorder. However, just how this occurs had remained obscure. Researchers are now able to answer this question, at least for one common genetic variant: this impairs the interoperation of certain ...
Recycler protein helps prevent disease
Thursday, April 30th, 2009(European Molecular Biology Laboratory) Researchers at the European Molecular Biology Laboratory and Heidelberg University, Germany, have now uncovered the first step in the recycling of a crucial molecular tag which ensures the instructions encoded in our genes are correctly carried out. The study, published this week in the journal Cell, ...

Thursday, April 30th, 2009(University of Toronto) A team of scientists from Canada, Spain and the United States has identified a key gene that allows plants to defend themselves against environmental stresses like drought, freezing and heat.
Gene test determines risk of heart surgery complications
Thursday, April 30th, 2009(Helmholtz Association of German Research Centres) Genetic differences can explain why some patients undergoing heart surgery later experience shock and kidney complications, according to a study by researchers at the Charite-Universitatsmedizin Berlin, the Max-Delbruck-Center for Molecular Medicine Berlin-Buch in Germany and the Austin Hospital in Melbourne, Australia. The results indicate ...
