Pharmaceutical SH2 domain–containing protein tyrosine phosphatase 2 inhibition suppresses primary and metastasized liver tumors by provoking hepatic innate immunity
Sign Up to like & getrecommendations! Published in 2022 at "Hepatology"
DOI: 10.1002/hep.32555
Abstract: Background and Aims: SH2 domain–containing protein tyrosine phosphatase 2 (Shp2) is the first identified pro‐oncogenic tyrosine phosphatase that acts downstream of receptor tyrosine kinases (RTKs) to promote Ras–extracellular signal–regulated kinase signaling. However, this phosphatase was… read more here.
