A novel, abundant sodium channel expressed in neurons and glia

Department of Cellular and Structural Biology, University of Colorado Health Sciences Center, Denver 80262, USA.
A novel, voltage-gated sodium channel cDNA, designated NaCh6, has been
isolated from the rat central and peripheral nervous systems. RNase
protection assays showed that NaCh6 is highly expressed in the brain, and
NaCh6 mRNA is as abundant or more abundant than the mRNAs for previously
identified rat brain sodium channels. In situ hybridization demonstrated
that a wide variety of neurons express NaCh6, including motor neurons in
the brainstem and spinal cord, cerebellar granule cells, and pyramidal and
granule cells of the hippocampus. RT-PCR and/or in situ hybridization
showed that astrocytes and Schwann cells express NaCh6. Thus, this sodium
channel is broadly distributed throughout the nervous system and is shown
to be expressed in both neurons and glial cells.
