Top: IgG IP (IgG), mTOR IP, ETV7 IP, Raptor IP, or Rictor IP of Karpas-299 cell lysate immunoblotted for mTOR, ETV7, Raptor, or Rictor. Bottom: Immunoblot of IgG IP (IgG), mTOR IP (mTORC1/2/3), ETV7 IP (mTORC3), Raptor IP (mTORC1), or Rictor IP (mTORC2) of Karpas-299 lysate incubated with recombinant GST-tagged P70S6K peptide after preincubation with vehicle (−) or rapamycin/FKBP-12 (+) (top blot), vehicle (−) or OSI-27 (+) (middle blot), and vehicle (−) or AZD-8055 (+) (bottom blot) was probed for p-P70S6KThr389. GST was used as a loading control.
