摘要

The Brn-3 sub group of POU family transcription factors has three members:- Brn-3a, Brn-3b and Brn-3c, all of which are expressed in distinct but overlapping groups of neuronal cells in the developing and adult nervous systems. Although these factors are closely related to one another, they have distinct functions. Thus, Brn-3a activates the expression of a number of different genes expressed in neuronal cells whereas Brn-3b represses their expression and inhibits activation by Brn-3a. These stimulatory effects of Brn-3a are paralleled by its ability to stimulate neurite outgrowth by neuronal cells and to protect them from apoptosis/programmed cell death. Thus Brn-3a may be of potential use in a gene therapy approach to human neurological diseases which involve either a failure of neurite outgrowth, such as spinal injury, or excessive neuronal cell death such as Alzheimer's or Parkinson's diseases.
