Activation of mitochondria and release of mitochondrial apoptogenic factors by betulinic acid.
Different classes of anticancer drugs may trigger apoptosis by acting on different subcellular targets and by activating distinct signaling pathways. Here, we report that betulinic acid (BetA) is a prototype cytotoxic agent that triggers apoptosis by a direct effect on mitochondria. In isolated mitochondria, BetA directly induces loss of transmembrane potential independent of a benzyloxycarbony...
متن کاملDifferentiation-dependent sensitivity to apoptogenic factors in PC12 cells.
We have investigated the role of the mitochondrial pathway during cell death following serum and nerve growth factor (NGF)/dibutyryl cyclic AMP (Bt(2)cAMP) withdrawal in undifferentiated or NGF/Bt(2)cAMP-differentiated PC12 cells, respectively. Holocytochrome c, Smac/DIABLO, and Omi/HtrA2 are released rapidly following trophic factor deprivation in PC12 cells. Bcl-2 and Akt inhibited this relea...
متن کاملCardiomyocyte mitochondria as targets of humoral factors released by remote ischemic preconditioning
INTRODUCTION Remote ischemic preconditioning (RIPC) reduces myocardial infarct size, and protection can be transferred with plasma to other individuals, even across species. Mitochondria are the end-effectors of cardioprotection by local ischemic conditioning maneuvers. We have now analyzed mitochondrial function in response to RIPC. MATERIAL AND METHODS Plasma from pigs undergoing placebo or...
متن کاملPhysicochemical characterization of cytostatic factors released from human monocytes.
Cultured human monocytes released cytostatic activity upon in vitro activation with lymphokines and lipopolysaccharide. This activity was mainly due to the presence of two different cytostatic factors, termed CstF I and II, which were separated by ion-exchange chromatography. At neutral pH, CstF I bound to the weak anion exchanger DEAE-Sephacel but not to the weak cation exchanger CM-Sepharose,...
متن کاملDifferential action of iodine on mitochondria from human tumoral- and extra-tumoral tissue in inducing the release of apoptogenic proteins.
Iodide is actively concentrated in the thyroid gland for thyroid hormone biosynthesis. Excess iodine has been observed to induce apoptosis in thyrocytes and mammary cells. The mechanism of iodine induced apoptosis is poorly understood. Among various cell organelles, mitochondria is known to provide conducive environment for the organification of iodine, i.e. iodination of different proteins. Mi...
