Zhang Y et al. indicated that Nedd4-2 may serve as a potential therapeutic target for the treatment of PD. [Read the Full Post]

Carcinoma-associated fibroblasts affect sensitivity to oxaliplatin and 5FU in colorectal cancer cells

467 views | May 23 2018

Gonçalves-Ribeiro S et al. showed that STAT3 or P38 inhibition provides a promising strategy for overcoming microenvironment-mediated resistance. Conversely, pharmacologic AKT inhibition induces an antagonistic effect that relieves a cMET and STAT3-mediated compensatory feedback that might explain the failure of AKT inhibitors in the clinic so far. [Read the Full Post]
