Beschreibung

Application

Calpain Inhibitor I have been used:

• as a component of protease inhibitor cocktail for gel shift analysis
• for treating HeLa cell cultures
• for inhibition of 26 S proteasome in 26 S proteasome inhibition assays

Biochem/physiol Actions

Can initiate apoptosis in HL-60 cells[1] but blocks dexamethasone-induced apoptosis in thymocytes and cycloheximide-induced apoptosis in metamyelocytes.[2] Inhibits cyclin B degradation and arrests the cell cycle at G₁/S and at meta-/anaphase.[3] Blocks induction of nitric oxide synthase by LPS in macrophages.[4]

Calpain Inhibitor I inhibits tumor necrosis factor-induced (TNF-induced) cleavage of Poly (ADP-ribose) polymerase (PARP) and calpastatin in apoptosis. It also inhibits oxygen/glucose deprivation (OGD) induced cleavage of caspase-12 and Bcl-xL..
