Abstract
To determine which thyroid receptor (TR) isoforms are expressed during oligodendrocyte differentiation, we studied the expression of the mRNAs encoding two alpha (alpha 1 and alpha 2) and one beta (beta 1) TR isoforms in a bipotential oligodendrocyte-type 2-astrocyte (O-2A) progenitor cell line (CG-4) as well as in rat O-2A progenitor cells and oligodendrocytes. O-2A progenitor cells expressed only TR alpha-mRNAs, whereas oligodendrocytes and type 2-astrocytes also expressed TR beta 1-mRNAs. The differential expression of alpha 1 and beta 1 TRs suggests specific functions for both types of TRs during oligodendrocyte differentiation. We present evidence for a possible role of TR alpha 1 in the effect of thyroid hormones on the proliferation of CG-4 cells maintained as progenitor cells.Entities:
