Studies that did not test the peptide alone2

In this study, IGF-1 LR3 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 LR3.

  1. 01LabNot a test of IGF-1 LR3 aloneIn vitro (cells)Efficacy outcome

    In human bronchial and tracheal epithelial cells, all analyzed growth factors, including the IGF-I analogue LongR3 IGF-I, significantly improved the rate of scratch closure.

    In plain wordsIn cells, every growth factor tested, including LongR3 IGF-I, sped up the closing of a scratch in lung airway cells.

    Summary
    All growth factors that were analyzed significantly improved the rate of scratch closure in bronchial and tracheal epithelial cells (p < or = 0.05).

    Human epithelial cell lines from the nasal, bronchial, and tracheal regions were analyzed for their response to IGF-I and IGF-II, in a confluent monolayer scratch assay.
    Summary · context
    Consequently, the analogues LongR3 IGF-I, Des1-3 IGF-I and Arg3 IGF-I were investigated also because of their lower affinity for the IGFBPs, while still retaining unaffected affinity for the IGF-I receptor.

    In this study, IGF-1 LR3 was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking IGF-1 LR3.

  2. 02LabNot a test of IGF-1 LR3 aloneIn vitro (cells)Efficacy outcome

    In human airway epithelial cells, the IGF-I analogues (LongR3, Des1-3 and Arg3 IGF-I) did not significantly improve scratch closure compared with IGF-I.

    In plain wordsIn cells, the IGF-I analogues, LongR3 IGF-I among them, did not close scratches better than IGF-I.

    Summary
    The IGF-I analogues did not significantly improve scratch closure compared with IGF-I, despite the presence of IGFBP-3 in nasal, bronchial, and tracheal epithelial cells.
