ANF mRNA is detected by the polymerase chain reaction technique in the chorioidea and bodies but not in the retina of the rat eye.
Specific proANF mRNA was demonstrated by the polymerase chain reaction (PCR) technique in ciliary body and chorioidea tissue extracts but not in the retina of the rat eye. However, immunoreactive (IR) ANF was detected in all of these tissues by a specific and sensitive radioimmunoassay (RIA). Since ANF seems to be involved in the maintenance of intraocular pressure, the regulation of ANF gene expression in these distinct eye tissues could be an important factor in the pathogenesis of glaucoma.
