Description

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

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..

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

Calpain activation in apoptosis.

M K Squìer et al.

Journal of cellular physiology, 159(2), 229-237 (1994-05-01)

Programmed cell death is an active process wherein the cell initiates a sequence of events culminating in the fragmentation of its DNA, nuclear collapse, and disintegration of the cell into small, membrane-bound apoptotic bodies. Examination of the death program in

Calpain inhibitors and serine protease inhibitors can produce apoptosis in HL-60 cells.

Q Lu et al.

Archives of biochemistry and biophysics, 334(1), 175-181 (1996-10-01)

Recent investigations indicate that proteolysis is an important event in generation of the apoptosis phenotype. Although various proteases have been suggested to be candidates for this proteolysis, the results from different laboratories are inconsistent. In the present studies, HL-60 cells
