Abstract
In order to determine whether striatal enkephalinergic neurons were affected by reversible focal ischemia, we have investigated the expression of the preproenkephalin (PPA) messenger by in situ hybridization (ISH) combined with TUNEL staining to display apoptosis in the same rat brain sections. Our data demonstrated a massive reduction of the number of PPA-mRNA containing neurons concomitant with the emergence of apoptotic cells. However, double-labeled neurons (ISH- and TUNEL-positive cells) were not detected, suggesting that either disruption of mRNA precedes DNA fragmentation or ischemia leads to a long lasting reduction of mRNA(s) without damage.
