IGFBP-1 and IGFBP-2 mRNAs are increased in the livers of streptozotocin-diabetic rats. A corresponding increase is observed in transcription of the IGFBP-1 but not the IGFBP-2 gene, indicating that the increase in steady-state levels of IGFBP-2 mRNA is a post-transcriptional effect. IGFBP-1 and IGFBP-2 mRNAs also differ in the rapidity of their response to insulin treatment: hepatic IGFBP-1 mRNA is normalized within 1 h, IGFBP-2 mRNA decreases more slowly. These differences suggest that IGFBP-2 may provide more chronic adaptation to metabolic change than IGFBP-1.

UI	MeSH Term	Description	Entries
D007328	Insulin	A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).

D007336	Insulin, Isophane	An intermediate-acting INSULIN preparation with onset time of 2 hours and duration of 24 hours. It is produced by crystallizing ZINC-insulin-PROTAMINES at neutral pH 7. Thus it is called neutral protamine Hagedorn for inventor Hans Christian Hagedorn.

D002467	Cell Nucleus	Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)	Cell Nuclei,Nuclei, Cell,Nucleus, Cell

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
