Physiological and induced neuronal death are not affected in NSE-bax transgenic mice

Abstract

Bax, a family member of the survival protein Bcl-2, is expressed in the nervous system during development and throughout adulthood. Bax deficiency has been demonstrated to prevent developmental and trophic factor deprivation-induced neuronal death. To further clarify the role of Bax in naturally occurring neuronal death and in neuronal death following apoptotic stimuli, we generated several lines of transgenic mice expressing the human Bax protein specifically in neurons, under the control of the neuron-specific enolase promoter. Transgene expression was first detected around E10.5 and E12.5, depending on the transgenic line. The total number of ganglion cells in the retina and of pyramidal ..
