For the first time UFZ study describes the effects of prenatal environmental stressors on the regulation of microRNAs The Leipzig Helmholtz Center for Environmental Research has gained new insights on the influence of tobacco smoke in utero. For the first time, it could be demonstrated with smoking pregnant women and their children, how exposure to tobacco smoke affects the development of human immune system on molecular level. The focus thereby was on microRNA – a short, single-stranded...

Biologists Show RNA Molecule Protects Stem Cells During Inflammation
2013-05-22 09:37:34

California Institute of Technology When infections occur in the body, stem cells in the blood often jump into action by multiplying and differentiating into mature immune cells that can fight off illness. But repeated infections and inflammation can deplete these cell populations, potentially leading to the development of serious blood conditions such as cancer. Now, a team of researchers led by biologists at the California Institute of Technology (Caltech) has found that, in mouse models,...
