  1. 01LabIn vitro (cells)Efficacy outcome

    In bovine granulosa cells grown without anchorage, the IGF-I analogue (LR3IGF-I) at 100 ng ml-1 significantly increased DNA synthesis.

    Summary
    Both IGF-I (100 ng ml-1) and IGF-II (100 ng ml-1) and their respective analogues, as well as insulin, all at the same concentration, significantly increased DNA synthesis as determined by [3H]thymidine incorporation (n = 5).

    Summary · context
    but not that stimulated by the analogue, LR3IGF-I, which has low affinity for IGFBPs.
    Summary · context
    The effects of insulin-like growth factors (IGFs) and insulin-like growth factor binding protein 1 (IGFBP-1) on the replication of such cells was investigated by isolating granulosa cells from follicles (3-5 mm diameter) from cyclic cows and culturing them in soft agar-methylcellulose solution.

Studies that did not test the peptide alone1

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

    In bovine granulosa cells, IGFBP-1 did not inhibit the cell division stimulated by LR3IGF-I, unlike that stimulated by IGF-I and IGF-II.

    In plain wordsIn cow granulosa cells, IGFBP-1 did not block the cell division caused by LR3IGF-I, but it blocked that caused by IGF-I and IGF-II.

    Summary
    IGFBP-1 significantly inhibited cell division stimulated by IGF-I (P < 0.001) and IGF-II (P < 0.001), but not that stimulated by the analogue, LR3IGF-I, which has low affinity for IGFBPs.
