Sheff JG et al. suggested that a different approach to inhibitor development may be fruitful. [Read the Full Post]

Calreticulin-mutant proteins induce megakaryocytic signaling to transform hematopoietic cells and undergo accelerated degradation and Golgi-mediated secretion

232 views | Aug 31 2018

Han L et al. demonstrated the potency of CALR mutants to drive expression of megakaryocytic differentiation markers such as NF-E2 and CD41 as well as Mpl. Furthermore, CALR mutants undergo accelerated protein degradation that involves the secretory pathway and/or protein glycosylation. [Read the Full Post]

The antibiotic polymyxin B exhibits novel antifungal activity against Fusarium species
