Pictilisib (GDC-0941)

Combination of rapamycin and PI-103 leads to the suppression of AKT phosphorylation (phospho-specific western blot). Mel-Juso and 518A2 cells were treated with GDC-0941 from 0.05–1 μmol/L alone and in combination with rapamycin (50 nmol/L) for 24 hours. Control treatment was with DMSO.

Growth inhibition induced by the FGFR inhibitor BGJ398 and the PI3K inhibitors alone or in combination. AN3CA (A-C), JHUEM2 (D-F) and MFE296 (G-I) cells were treated with the indicated doses of BGJ398, GDC-0941 a n d BYL719 alone or in combination for 96 hours and an Sulforhodamine B (SRB) assay was subsequently performed. Data are presented as a percentage of the control, in which cells were treated with 0.1% (v/v) DMSO. Points represent the mean of three independent experiments (each performed in triplicate). Error bars represent the standard error of the mean (SEM) and lines were fitted using non-linear regression analysis. Interaction of BGJ398 and GDC-0941(redcircles) or BYL719(blacksquares) in AN3CA(C), JHUEM2(F) and MFE296(I). Median effect analysis was used to evaluate the interaction between the inhibitor combinations. Horizontal dotted lines indicate the boundaries for each interaction classification.

TGF-β induces mTORC2 activation. ( A ) NMuMG cells were treated with TGF-β for the indicated times before lysis and immunoblotting. (B ) NMuMG cells were treated or not with TGF-β for the indicated times, in the presence or absence of SB431542 or LY294002. Cell lysates were subjected to anti-Rictor immunoprecipitation, and the immunoprecipitates were subjected to in vitro kinase assays using kinase-inactive Akt1 as a substrate, before immunoblotting of the kinase reactions, immunoprecipitates and cell lysates. The left panels are from the same gel, without differential exposure. ( C ) NMuMG cells were treated or not with TGF-β or insulin for the indicated times, in the presence or absence of SB431542 or GDC-0941. The kinase activity of mTORC2 was then assessed as in B. The top panels are from the same gel, without differential exposure. (D) NMuMG cells were treated or not with TGF-β for the indicated times, in the presence or absence of SB431542 or LY294002. Cell lysates were subjected to immunoprecipitation using Rictor antibody, and/or immunoblotted.

Effects of LY294002 and GDC-0941 on the high-glucose-induced plasma membrane translocation of DGK δ1. (A, C) HEK293 cells were transfected with pAcGFP-DGKδ1 or pAcGFP-C1 vector. After being glucose-starved for 2.5 h and the subsequent pretreatment with (A) 10 μM LY294002 (Sigma-Aldrich) or (C) 1 μM GDC-0941 (Selleck Chemicals) for 30 min, the cells were incubated with or without high glucose (25 mM) for 5 min. The cells were fixed with 3.7% formaldehyde and observed using confocal laser-scanning microscopy. Scale bar = 10 μm. (B, D) After treatment with (B) LY294002 or (D) GDC-0941, the percentages of cells exhibiting the translocation of AcGFP-tagged DGK δ 1 to the plasma membrane were scored. More than 20 cells ex-pressing AcGFP-tagged DGK δ1 were counted in each experiment. The results are the means ± S.D. of three independent experiments. The statistical significance was deter-mined using Student's t -test (** P < 0.01, *** P < 0.005)

We treated all of drugs in T47D which has a PI3KCA H1044R mutation with the concentration shown below for 1 hour and performed western blot analysis using antibodies to phospho-AKT(SERINE 472), and total AKT.

PI3K pathway signaling in GDC-0941 and MK-2206 treated MCF-7 derivatives with PIK3CA or  AKT1 mutations. Cells were grown in medium containing 5% FBS and treated with vehicle or increasing concentrations of GDC-0941 (0 nM, 50 nM, 100 nM, and 400 nM) or MK-2206 (0 nM, 100 nM, 250 nM, 1000 nM). After 24 hours of drug treatment, lysates were prepared and equal amounts of protein were load ed onto SDS-PAGE gels and blotted with the indicated antibodies.
