Surprising signal to control male fertility

by Koh - Sperm cells mature during their transit in the epididymis and thus acquire their ability to fertilize ova. Scientists from the German Cancer Research Center (DKFZ) in Heidelberg and the Institute of Molecular Biology in Mainz have now discovered that signaling molecules of the Wnt family of proteins coordinate this maturation process. A surprising finding is that Wnt signaling, which is extremely important in embryonic development and also in the development of diseases, acts upon spermatozoa in a way that differs from the known one. ...

A Precision Medicine Approach to Nanomedicine: New Method Developed to Predict Response to Nanotherapeutics

Many nanotherapeutics are currently being tested in clinical trials and several have already been clinically approved to treat cancers. But the ability to predict which patients will be most responsive to these treatments has remained elusive. Now, a collaboration between investigators at Massachusetts General Hospital (MGH) and Brigham and Women’s Hospital (BWH) has led to a new approach that uses an FDA-approved, magnetic nanoparticle and magnetic resonance imaging (MRI) to identify tumors most likely to respond to drugs delivered via nanoparticles. ...

Discovery: Molecular Mechanism at Root of Familial Amyloidosis and Other Diseases

(Boston)—A team of local researchers has proposed a molecular mechanism that may be responsible for the development of life-threatening diseases called amyloidoses. The best known of such diseases is Alzheimer’s disease (AD), but there are many others that are receiving increased scrutiny, in part because of mounting evidence linking them to atherosclerosis and aging. ...
