Differentiation-dependent expression of transgenes in engineered astrocyte cell lines

Neuroscience Letters

Abstract

The utility of transgenes for both basic and applied studies has been augmented by the recent advent of versions that can be regulated by the addition of suitable activators. However, still more convenient would be transgenes whose expression responded appropriately to endogenous signals. The promoter of the glial fibrillary acidic protein (GFAP) gene is a candidate for this role in the central nervous system (CNS) since the GFAP gene is specifically expressed in astrocytes in the CNS and its activity is upregulated in response to almost any CNS injury. As a feasibility study, we isolated a C6 rat glioma cell line stably transfected with a lacZ reporter gene driven by the gfa2 human GFAP promoter fragment. We find that the activity of the transgene indeed responds to an environmental signal, forskolin, that induces astrocyte-like differentiation of C6 cells. We also isolated a C6 line carrying a transgene in which the gfa2 promoter directs expression of a cDNA for tyrosine hydroxylase (TH), the rate-limiting enzyme for catecholamine synthesis. This transgene should be of considerable interest for gene therapy for Parkinson's disease. We show that in this cell line both TH mRNA and protein are upregulated by forskolin. Finally, ...Continue Reading

Astrocytes in Parkinson Disease

Parkinson's disease (PD) is a neurodegenerative disorder caused by the progressive loss of dopaminergic neurons. Some PD-genes may be associated with astrocyte dysfunction. Discover the latest research on astrocytes in Parkinson's disease here.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.
