Expression of IGF-II and H19 mRNA in the neonatal rat during normal maturation and after dexamethasone administration
in Journal of Molecular EndocrinologyABSTRACT
In this study, the expression of IGF-II and H19 was examined in the liver, skeletal muscle and choroid plexus of the neonatal rat during normal maturation and after the administration of dexamethasone. If the two genes share common regulatory elements as postulated by an enhancer competition system, their patterns of expression should remain similar throughout maturation and after treatment with dexamethasone. In the liver, down-regulation of IGF-II and H19 during maturation and after dexamethasone administration was shown. This is consistent with the hypothesis that IGF-II and H19 are regulated by common enhancers. In the secretory cells of the choroid plexus, where expression of IGF-II is known to be biallelic, IGF-II was expressed in both untreated and dexamethasone-treated animals, regardless of age, whereas H19 expression was not detectable. This is consistent with the postulate that only one gene from each allele can be engaged by the enhancers. In skeletal muscle, H19 continues to be expressed in the adult after IGF-II is switched off suggesting that IGF-II can also be regulated independently of H19.
Journal of Molecular Endocrinology is committed to supporting researchers in demonstrating the impact of their articles published in the journal.
The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
