    mTORC1 regulates KPNA2 transcription but not S6K1- and 4E-BP1-dependent translation. KPNA2 abundances in response to S6K1 inhibition are detected by Western blot analysis in WT and TSC2−/− MEFs.

    Description

    PF-4708671 is a potent cell-permeable S6K1 inhibitor with a Ki of 20 nM and IC50 of 160 nM.

    IC50 & Target

    S6K1

    160 nM (IC50)

    S6K1

    20 nM (Ki)

    S6K2

    65 μM (IC50)

    In Vitro

    PF-4708671 inhibits the activity of full-length S6K1 in vitro with a Ki of 20 nM, and S6K1 isolated from IGF1-stimulated HEK293 cells with an IC50 of 0.16 μM, and only inhibits very weakly the closely related S6K2 isoform (IC50 of 65 μM). PF-4708671 inhibits RSK1 (IC50 of 4.7 μM) and RSK2 (IC50 of 9.2 μM) over 20-fold less potently than S6K1. PF4708671 inhibits MSK1 (IC50 of 0.95 μM) 4-fold more weakly than S6K1[1]. HCT116 cells are treated with (i) vehicle (DMSO), (ii) OSI-906 (5 μM), (iii) PF-4708671 (10 μM), and (iv) OSI-906 (5 μM)+PF-4708671 (10 μM) for various amounts of time. HCT116 cells treated with OSI-906 alone (closed square) or PF4708671 alone (open circle) slightly inhibit cell growth. In contrast, proliferation in HCT116 cells is significantly inhibited after a 2-day treatment with the combination of OSI-906 and PF-4708671 (closed circle). A similar result is also observed when SW480 cells are treated with the combination of OSI-906 and PF-4708671. Colony formation also significantly reduces in OSI-906+PF-4708671-treated cells comparing with vehicle, OSI-906 alone, or PF-4708671 alone treated HCT116 or SW480 cells[2].

    In Vivo

    The tumor growth rate in mice treated with the combination of OSI-906+PF-4708671 is significantly slower than that of OSI-906 alone (P=0.0189) or PF4708671 alone (P=0.0165) treated mice. The average tumor volume in the OSI-906+PF-4708671-treated mice is approximately 50% of that in mice treated with OSI-906 (P=0.0056) or PF-4708671 alone (P<0.001) at the end of a 15-day treatment[2].

    Cell Assay
    [2]

    GEO, HT29, SW480, and HCT116 cells are used. The effects of OSI-906 or the combination of OSI-906 and PF-4708671 on cell proliferation is determined with XTT and clonogenic assays. XTT assays are performed using the Cell Proliferation Kit II (XTT). For clonogenic assays, cells (1×103 cells/well) are seeded on a 6-well plate and subsequently treated with drugs (OSI-906 5 μM, PF-4708671 10 μM). After 1 week of incubation, cells are stained with 1% crystal violet, and the number of colonies is counted and recorded[2].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [2]

    Mice[2]
    Five- to 6-week-old female athymic nude mice (Hsd:Athymic Nude-Foxn1nu) are randomly assigned to the following groups (5 mice/group). For injection of HT29-L and HT29-P cells, mice are treated with vehicle (25 mM tartaric acid) or OSI-906 (30 mg/kg) for 12 days. For injection of HCT116 cells, mice are treated with (i) vehicle (25 mM tartaric acid); (ii) OSI-906 alone (30 mg/kg); (iii) PF-4708671 alone (60 mg/kg); and (iv) OSI-906 (30 mg/kg)+PF-4708671 (60 mg/kg) and treated with drugs orally for 14 days. Vehicle and OSI-906 are given once per day and PF-4708671 is given once every other day. Twenty-four hours after the last treatment, the mice are sacrificed and the tumor weights were measured[2].
