    Customer Validation
     Transient hyperglycemia accompanied by ephemeral hyperinsulinemia induced by IR and IGF1R inhibition with OSI-906. C57BL/6J mice are subjected to a 16-hour fast and OSI-906 (45 mg/kg) or a vehicle (Solutol HS-15) is administered orally 1 hour before injection with either saline, 10 units of insulin, or 1 mg/kg of IGF-1 via the inferior vena cava. The liver and epididymal fat are collected 70 and 120 seconds after injection, respectively.

     OSI-906 inhibits p-IGF1R and IGF1R signaling factors in breast cancer cell-lines. 3 × 105 ER-positive MCF7 and ER-negative are plated per well of a 6-well plate and cultured for 24 h and subsequently treated with the OSI-906 (0.1, 0.4 and 1.6 μM) and/or SKI-II (4 μM) for 24 h. Protein lysates are collected and 20 μg of protein is used for immunoblot analysis to measure changes to IGF1R signaling and SphK1 steady-state protein expression levels.

    Customer Validation
     Expression of Sema4D and PlexinB1 in various oral squamous cell carcinoma cell lines following the addition of IGF-I. Notably, the addition of IGF-I resulted in increased expression of Sema4D, particularly in HSC-2 and SAS cells. This increase was suppressed when IGF-I was administered in the presence of inhibitors targeting its receptor or downstream signaling pathways. No changes in PlexinB1 expression were observed following the addition of IGF-I.

    Customer Validation
     OSI-906 inhibits insulin receptor-mediated signaling in HEK293 cells. The cells are deprived of serum for 2 hours, stimulated for 5 min with 1 μM i nsulin in the presence or absence of 200 nM OSI-906 in serum-free medium. Cell extracts are subjected to immunoprecipitation and immunoblotting, as indicated.
