TLDR
It is demonstrated that betanin induces apoptosis in K562 cells through the intrinsic pathway and is mediated by the release of cytochrome c from mitochondria into the cytosol, and PARP cleavage.

Rapid colorimetric assay for cellular growth and survival: Application to proliferation and cytotoxicity assays

TL;DR: A tetrazolium salt has been used to develop a quantitative colorimetric assay for mammalian cell survival and proliferation and is used to measure proliferative lymphokines, mitogen stimulations and complement-mediated lysis.
Journal ArticleDOI

Mitochondria and apoptosis

TL;DR: A variety of key events in apoptosis focus on mitochondria, including the release of caspase activators (such as cytochrome c), changes in electron transport, loss of mitochondrial transmembrane potential, altered cellular oxidation-reduction, and participation of pro- and antiapoptotic Bcl-2 family proteins.
Journal ArticleDOI

Mitochondrial control of cell death

TL;DR: In many instances, permeabilization of mitochondrial membranes is a rate-limiting step of apoptotic or necrotic cell demise, which has important consequences for the pathophysiology of cell death, as well as for its pharmacological control.
Journal ArticleDOI

Mitochondria as the central control point of apoptosis

TL;DR: The current view of the mechanisms that lead to the efflux of many proteins from mitochondria during apoptosis and the role played by Bcl-2 family proteins in the control of this event are summarized.
