In Vitro	GDC-0941 and docetaxel reduce tumor cell viability by 80% or greater in the breast cancer cell lines than single-agent treatment. GDC-0941 inhibits Akt phosphorylation and downstream targets of Akt signaling such as pPRAS40 and pS6 in Hs578T1.2 (PI3Kα wild-type), MCF7-neo/HER2 (PI3Kα-mutant), and MX-1 (PTEN-null) tumor models. GDC-0941 decreases the time of docetaxel-induced mitotic arrest prior to apoptosis[1]. GDC-0941 shows a high efficacy of antitumor activity in two gefitinib-resistant non-small cell lung cancer (NSCLC) cell lines, A549 and H460. GDC-0941 is highly efficacious in combination with U0126 in inducing cell growth inhibition, G0-G1 arrest and cell apoptosis. H460 cells with activating mutations of PIK3CA are relatively more sensitive to GDC-0941 than A549 cells with wild-type PIK3CA[3]. GDC-0941 reduces PI3K pathway activity in both cell lines, illustrated by decreased pAK. GDC-0941 significantly reduces secreted VEGF detected in the medium after hypoxic/anoxic exposure in all cells[4].
In Vivo	GDC-0941 (150 mg/kg, p.o.) leads to tumor stasis in MCF7-neo/HER2-bearing animals model. GDC-0941 and docetaxel result in tumor regressions during the treatment period leading to enhanced antitumor responses[1]. Tumours in the GDC-0941-treated mice show a marked non-linear shrinkage, and when the GDC-0941 treatment ceased, the tumours in the test cohort mice grow again[2]. GDC-0941 (25 or 50 mg/kg) reduces tumor growth and PI3K and HIF-1 pathway activity in eGFP-FTC133 tumor-bearing mice[4].
Cell Assay	Cells are treated at EC50 concentrations of GDC-0941, docetaxel, or both for 4 or 24 hours and lysed in 1×Cell Extraction Buffer supplemented with protease inhibitors and Phosphatase Inhibitor Cocktails 1 and 2. Protein concentrations are determined using the Pierce BCA Protein Assay Kit. For immunoblots, equal amounts of protein are separated by electrophoresis through NuPAGE Bis-Tris 10% gradient gels, transferred onto polyvinylidene difluoride membranes using the Criterion system, and probed with monospecific primary antibodies. Specific antigen-antibody interactions are detected with IRDye 680 or IRDye 800 infrared secondary antibodies using a LI-COR imaging system[1].
Animal Admin	Mice[1] Female nu/nu mice are inoculated subcutaneously with MCF7-neo/HER2 or MX-1 breast cancer cells. When tumors reach a mean volume of 200 to 250 mm3, animals are size-matched and distributed into groups consisting of 10 animals per group. Docetaxel formulated in 3% EtOH, 97% saline is administered intravenously once weekly. GDC-0941, formulated in MCT (0.5% methylcellulose, 0.2% Tween-80) is dosed orally and daily. MAXF1162 is an HER2+/ER+/PR+ patient-derived breast cancer tumor xenograft model established by directly implanting tumors subcutaneously from patient to NMRI nu/nu mice. Tumor volume is calculated. Tumor sizes are recorded twice weekly over the course of a study.
