An Apoptosis-inducing Isoform of Neu Differentiation Factor (NDF) Identified Using a Novel Screen for Dominant, Apoptosis-inducing Genes
Apoptosis is a genetically programmed series of events that results in cell death. As a consequence, it is difficult to identify dominant genes that play a role in this process using genetic selections in conventional cell culture systems. Accordingly, we have established an efficient expression screen to isolate dominant, apoptosis-inducing genes. The assay is based on the apoptotic morphology...
متن کاملNeu Differentiation Factor (NDF), a Dominant Oncogene, Causes Apoptosis In Vitro and In Vivo
Neu differentiation factor (NDF, also called neuregulin) is a potent inducer of epithelial cell proliferation and has been shown to induce mammary carcinomas in transgenic mice. Notwithstanding this proliferative effect, we have shown that a novel isoform of NDF can induce apoptosis when overexpressed. Here we report that this property also extends to other NDF isoforms and that the cytoplasmic...
متن کاملApoptosis-inducing factor
Although the seminal paper by Kerr, Wyllie and Currie (Kerr et al., 1972), who coined the word ‘apoptosis’, stated that only nuclei but not cytoplasmic organelles would undergo major modifications in the dying cell, recent evidence suggests that no cellular compartment is spared (Ferri and Kroemer, 2001). Mitochondria are particularly affected early during the apoptotic process, and they are no...
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 کاملDominant cell death induction by extramitochondrially targeted apoptosis-inducing factor.
The complete AIF cDNA comprising the amino-terminal mitochondrial localization sequence (MLS) and the oxidoreductase domain has been fused in its carboxyl terminus to enhanced green fluorescent protein (GFP), thereby engineering an AIF-GFP fusion protein that is selectively targeted to the mitochondrial intermembrane space. Upon induction of apoptosis, the AIF-GFP protein translocates together ...
