Chelerythrine induces apoptosis through a Bax/Bak-independent mitochondrial mechanism.
Although murine embryonic fibroblasts (MEFs) with Bax or Bak deleted displayed no defect in apoptosis signaling, MEFs with Bax and Bak double knock-out (DKO) showed dramatic resistance to diverse apoptotic stimuli, suggesting that Bax and Bak are redundant but essential regulators for apoptosis signaling. Chelerythrine has recently been identified as a Bcl-xL inhibitor that is capable of trigge...
متن کاملPyruvate induces mitochondrial biogenesis by a PGC-1α independent mechanism
Oxidative cells increase mitochondrial mass in response to stimuli such as changes in energy demand or cellular differentiation. This plasticity enables the cell to adapt dynamically in order to achieve necessary oxidative capacity. However, the pathways involved in triggering mitochondrial biogenesis are poorly defined. The present study examines the impact of altering energy provision on mito...
متن کاملPerfluorooctanesulfonate (PFOS) Induces Apoptosis Signaling and Proteolysis in Human Lymphocytes through ROS Mediated Mitochondrial Dysfunction and Lysosomal Membrane Labialization
Perfluorinated compounds (PFCs) such as perfluorooctanesulfonate (PFOS) are stable chemicals that accumulate in biological matrix. Toxicity of these compounds including immunotoxicity has been demonstrated in experimental models and wildlife. Although limited number of studies examined the effects of PFOS on human lymphocytes but so far no research has investigated the complete mechanisms of PF...

متن کاملHydrogen peroxide induces apoptosis in HeLa cells through mitochondrial pathway.
Cervical cancer is the most common cancer amongst females in India and is associated with high risk HPVs, reactive oxygen species (ROS), and excessive inflammation in most cases. ROS in turn affects the expression of pro- and anti-apoptotic proteins. The objective of the present study was to elucidate the effect of hydrogen peroxide (H(2)O(2)) on apoptotic signaling molecules in vitro. HeLa cel...
