Berberine Induces Caspase-Independent Cell Death in Colon Tumor Cells through Activation of Apoptosis-Inducing Factor
Berberine, an isoquinoline alkaloid derived from plants, is a traditional medicine for treating bacterial diarrhea and intestinal parasite infections. Although berberine has recently been shown to suppress growth of several tumor cell lines, information regarding the effect of berberine on colon tumor growth is limited. Here, we investigated the mechanisms underlying the effects of berberine on...
متن کاملApoptosis-inducing factor is involved in the regulation of caspase-independent neuronal cell death
Caspase-independent death mechanisms have been shown to execute apoptosis in many types of neuronal injury. P53 has been identified as a key regulator of neuronal cell death after acute injury such as DNA damage, ischemia, and excitotoxicity. Here, we demonstrate that p53 can induce neuronal cell death via a caspase-mediated process activated by apoptotic activating factor-1 (Apaf1) and via a d...
متن کاملvital functions of apoptosis inducing factor (aif)
in many models of programmed cell death, the mitochondrial protein aif translocates to the nucleus, where it induces the chromatin condensation and dna degradation. however, today it is well established that this flavoprotein is bifunctional. in addition to its lethal function in the nucleus of dying cells, aif plays a vital bioenergetic role in healthy ones by regulating mainly the activity of...

متن کاملPossible contribution of apoptosis-inducing factor (AIF) and reactive oxygen species (ROS) to UVB-induced caspase-independent cell death in the T cell line Jurkat.
We analyzed the mechanism of UVB-induced cell death using the Jurkat T cell line. Apoptosis was assessed by measuring phosphatidylserine (PS) externalization, caspase activity, the decrease in mitochondrial membrane potential (Delta Psi m), nucleosomal DNA fragmentation, and morphological changes such as chromatin condensation. The mitochondrio-nuclear translocation of apoptosis-inducing factor...
