Localization of calcitonin and calcitonin gene-related peptide mRNAs in rat parafollicular cells by hybridocytochemistryM Zabel and H Schafer Institut of Pathology, University of Hamburg, Federal Republic of Germany. By use of appropriate fragments of CT DNA or a CGRP DNA and SP6 polymerase system, we produced anti-sense RNA probes labeled with biotinylated 11-UTP. The labeling and specificity of the RNA probes were confirmed using dot-blot hybridization. By use of hybridocytochemistry, CT mRNA and CGRP mRNA were localized in all parafollicular cells in control and dihydrotachysterin-pre-treated rats. We concluded that all parafollicular cells simultaneously produce both CT mRNA and CGRP mRNA, either under control conditions or after stimulation by dihydrotachysterin-induced hypercalcemia.
