Connexin43 (cx43) mRNA and protein were quantified in seven brain regions u
sing RNase protection assays and Western blotting from postnatal day 3, 10,
and 17, and adult Sprague-Dawley rats. Increases in cx43 mRNA abundance pr
eceded strong increases in cx43 protein in the cerebral cortex, hippocampus
, hypothalamus, and striatum, whereas smaller postnatal increases were seen
in the cerebellum, brain stem, and olfactory bulbs. (C) 1999 Elsevier Scie
