in order to study the possible role of gene transcription in this process , expression of four individual rnas was investigated in the gerbil brain after 5 min of global cerebral ischemia by in situ hybridization with the following nucleic acid probes : plasmid pmr100 ( ribosomal rna sequences ) , plasma pag82 ( cytochrome c oxidase sequences ) , plasmid p629 ( amyloid a4 precursor protein of alzheimer 's disease , pre-a4 protein ) , and plasmid phf beta a-1 ( beta-actin sequences ) .
