We have investigated the transcription of IGF-I and IGF-II genes in the adult rat eye. Each eye was dissected into cornea, lens, sclera + choroid + pigment epithelium, and neural retina. Total cellular RNA was isolated from each of these tissues. Northern blot analysis using rat coding region cDNA probes revealed the presence of IGF-I and IGF-II specific transcripts in the retina and the sclera but not in the lens and cornea. Retina demonstrated the highest level of IGF-I and IGF-II expression. Our results suggest autocrine and paracrine effects of the IGFs and their possible involvement in normal eye physiology as well as in the pathogenesis of certain eye diseases.
