Mechanism of Cdo-induced Wnt suppression during neuronal differentication

4174 views | Nov 28 2014

Jeong et al. found that Wnt signaling is negatively regulated by Cdo, a Shh multifunctional co-receptor which is highly expressed in the central nervous system, in order to promote neuronal differentiation. [Read the Full Post]

Quickly switching of spindle checkpoint states is due to negative feedback at kinetochrores

4089 views | Nov 27 2014

Nijenhuis et al. found this phenomenon arises due to localized negative feedback of spindle assemble checkpoint (SAC) signal, which ensure kinetochres switch SAC signalling OFF rapidly. [Read the Full Post]
