1 RESULTS: Pretreatment with sorafenib enhanced bortezomib-induced apoptotic cell death by restoring bortezomib"s ability to inactivate Akt in PLC/PRF/5 cells. Sorafenib heparan sulfate proteoglycan 2 Homo sapiens
2 Notably, sorafenib with bortezomib increased PP2A activity in PLC/PRF/5 cells without altering protein levels of PP2A complex or the interaction between PP2A and Akt proteins. Sorafenib heparan sulfate proteoglycan 2 Homo sapiens
3 Finally, sorafenib plus bortezomib significantly suppressed PLC/PRF/5 xenograft tumor growth, down-regulated P-Akt expression, and up-regulated PP2A activity. Sorafenib heparan sulfate proteoglycan 2 Homo sapiens
