Insulin-like growth factor II (IGF-II) is believed to be involved in the development of the fetus. Northern and dot-blot analysis of RNA isolated from different sheep tissues at various stages of development were undertaken, revealing that the ovine IGF-II gene is expressed as a multitranscript family (6.0, 5.1, 5.0, 4.7, 3.8, 2.9, 2.3, 1.9, 1.6, 1.3 kb). Evidence that the ovine IGF-II gene may be regulated in a developmental, tissue-specific, co-ordinate or independent manner is presented. The developmental profile of IGF-II gene expression correlates with plasma levels (Mesiano et al. (1989) Endocrinology 124, 1485-1491), and suggests that the rapid fall in plasma concentration at term can be attributed to regulation at the transcriptional level. With the exception of the kidney, IGF-II expression was down-regulated at birth in all tissues examined. As in man but not rat, an adult liver-specific transcript was detected and attributed to different 5' untranslated regions in the fetal and adult IGF-II mRNAs. The finding of IGF-II transcripts in all tissues examined supports evidence from other species of autocrine/paracrine roles for IGF-II in the development of the fetus.
