    2 context sentences
    Summary · context
    SH-SY5Y human neuroblastoma cells express IGF receptors, IGFs and IGF binding proteins (IGFBPs), and provide a model for studying the role of the IGF system in human neuronal development.
    Summary · context
    We investigated the effect of IGF-I and des(1-3)IGF-I on the motility of SH-SY5Y cells by a cell migration assay based on the assessment of the number of cells which migrated across 8 microm pore size membranes and around an agarose drop.

    Summary
    Treatment of cells with these agents for 24 h resulted in a significant increase (IGF-I by 70% and des(1-3)IGF-I by 90%; P<0. 0001) in cell motility relative to control conditions.

Studies that did not test the peptide alone1

In this study, IGF-1 DES (des(1-3)IGF-I) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking IGF-1 DES (des(1-3)IGF-I).

  1. 03LabNot a test of IGF-1 DES (des(1-3)IGF-I) aloneIn vitro (cells)Mechanism

    Type 1 IGF receptor antibody reduced des(1‑3)IGF-I-induced SH-SY5Y cell motility by 70%.

    In plain wordsIn cells, a receptor-blocking antibody reduced movement induced by des(1‑3)IGF-I compared with peptide alone.

    Summary
    Addition of monoclonal antibody against type 1 IGF receptor (alpha-IR3), significantly (P<0.05) reduced the cell motility induced by IGF-I (by 30%) and des(1-3)IGF-I (by 70%).
